Executive Product Architectural Overview
The XRN-3220B4/KME sits at the center of an IP surveillance architecture rather than operating as a simple storage appliance. Its job is to ingest camera streams, maintain reliable recording, index event data, present live and recorded video, expose controlled remote access, trigger downstream actions and preserve evidential footage across a storage design that may contain many disks. For enterprise buyers, this distinction matters because recorder sizing must account for far more than the headline channel count. Thirty-two cameras can represent a modest office deployment using low-to-medium bitrates, or a highly demanding critical-site environment using multi-megapixel cameras, analytics metadata, high frame rates and long retention periods. The XRN-3220B4 is designed to give system integrators sufficient headroom for such demanding scenarios by combining a 32-channel ceiling with recording bandwidth that reaches 520 Mbps in supported distributed or RAID operating modes.
The recorder supports H.265, H.264 and MJPEG, allowing it to coexist with different stream types and migration stages. H.265 is typically preferred where compatible because storage consumption and network load can be materially lower than older compression methods for a given visual target, although actual savings vary by scene movement, lighting, camera settings and encoder implementation. Camera input support spans resolutions up to 32 MP. This does not mean every channel can necessarily be viewed at the maximum resolution and frame rate simultaneously on every local display layout; decoding and live-view composition are separate resource considerations. Hanwha specifies local display modes that include 32 MP at 15 fps in H.265, 12 MP at 30 fps in H.265, 8.3 MP across four channels at 30 fps, 1080p across sixteen channels at 30 fps and 720p across thirty-two channels at 30 fps. These published limits help surveillance designers distinguish recording capacity from simultaneous local decoding requirements.
Storage architecture is one of the XRN-3220B4/KME’s strongest enterprise attributes. The chassis contains sixteen SATA bays with hot-swap capability and supports up to 10 TB per validated drive, for a raw non-RAID total of up to 160 TB. In production surveillance deployments, raw capacity should never be confused with usable protected capacity. RAID 5 and RAID 6 are supported, with the manufacturer documenting two arrays of up to eight drives each. The chosen RAID level, drive count and filesystem behavior reduce usable space, while camera bitrate and retention policy determine how quickly that space fills. RAID is designed to improve storage availability during disk failure scenarios; it is not an archive, backup or substitute for evidence export procedures. Where longer retention or centralized storage is needed, the recorder also supports iSCSI storage, enabling a properly engineered external storage target to become part of the design.
Operational continuity extends beyond disks. N+1 failover support allows a surveillance architecture to incorporate recorder redundancy, subject to proper system design, supported configurations and deployment planning. Automatic Recovery Backup is also supported. For sites with business-critical monitoring—such as distribution centers, control rooms, campuses, financial offices or public-sector facilities—these functions can be more important than nominal channel count because the goal is to reduce the impact of recorder outages and maintenance events. Hot-swap disk access further supports serviceability by reducing the need for extended chassis downtime when replacing a failed supported drive.
The network and integration layer is equally relevant. Three RJ-45 1 GbE interfaces are provided for LAN/WAN connectivity. The recorder supports IPv4 and IPv6 plus protocols such as TCP/IP, UDP/IP, RTP, RTSP, NTP, HTTPS, SNMP and ONVIF Profile S, while Hanwha SUNAPI supports integration within the manufacturer ecosystem and with compatible third-party platforms. Viewer options include WAVE, SSM, Webviewer, Wisenet Viewer and Wisenet mobile. Security features include IP address filtering, user access logs, 802.1X, TLS, encrypted device certificates, signed firmware and integrated TPM support. These capabilities enable a security team to place the recorder inside a broader identity, certificate, segmentation and monitoring framework rather than treating the NVR as an isolated edge device.
In the UAE, environmental and facilities planning must also be deliberate. The published operating temperature is 0°C to 40°C with 20% to 85% relative humidity. This is equipment-room guidance, not an invitation to place the recorder in an unconditioned external cabinet exposed to summer heat. Rack design should consider airflow, dust control, UPS-backed power, cable management and service clearance. The chassis measures approximately 440 × 132 × 571.1 mm and weighs around 14 kg without HDDs. Once sixteen drives are installed, rack loading and rail or shelf selection should account for the additional mass. FourTeck can help buyers translate these technical limits into a bill of materials that includes appropriate drives, rack placement, network uplinks, display requirements, power continuity and integration assumptions before the purchase order is finalized.
Enterprise Business Value & ROI Benefits
Recording Performance
Up to 520 Mbps recording bandwidth in supported modes gives designers meaningful headroom for high-resolution and higher-frame-rate camera fleets. Business value comes from being able to consolidate demanding streams into a recorder platform sized for modern IP surveillance rather than splitting cameras prematurely across multiple undersized recorders. Correct bitrate modelling remains essential because camera count alone does not predict load.
Storage Resilience
Sixteen hot-swap bays and RAID 5/6 give administrators flexibility to balance capacity, fault tolerance and serviceability. For operations teams, this can reduce disruption associated with individual drive failures and makes scheduled maintenance more practical. The commercial benefit is strongest when the array is paired with compatible surveillance drives, health monitoring and defined replacement procedures rather than treated as unmanaged bulk storage.
Security Architecture
TPM, signed firmware, TLS, 802.1X and access logging help security teams integrate the NVR into enterprise hardening policies. These controls do not replace segmentation, credential governance or patch management, but they reduce dependence on weak perimeter-only assumptions and support a more defensible recorder deployment for regulated and security-sensitive environments.
Operational Continuity
N+1 failover support and Automatic Recovery Backup provide building blocks for higher-availability recording architectures. A correctly designed failover plan can reduce the exposure created by a single recorder outage, improving continuity for sites where missing footage could create operational, investigative or compliance consequences.
Investigation Efficiency
Time, event, text, bookmark and smart-search workflows, plus AI search when used with compatible Hanwha AI cameras, can shorten the path from incident report to relevant footage. Faster retrieval can reduce the labor spent manually scrubbing timelines and can help security teams respond more consistently to operational events.
Integration Flexibility
ONVIF, SUNAPI, SNMP, web access and supported Hanwha viewing platforms allow the recorder to participate in broader monitoring environments. This matters to buyers replacing legacy systems because a recorder purchase is rarely isolated; cameras, VMS clients, monitoring stations, networks, storage and alerting procedures must work together.
Return on investment in surveillance should be evaluated through risk reduction, administration time, evidence availability, system uptime and avoided redesign rather than a simplistic lowest-price comparison. A recorder with sufficient throughput, storage serviceability and integration options can reduce future forklift upgrades when camera resolutions or retention demands rise. Conversely, over-sizing storage without a defined retention policy wastes capital. FourTeck therefore recommends that buyers document camera count, codec, average and peak bitrate, recording schedule, retention target, RAID policy and expected growth before comparing commercial proposals.
Hardware & Technical Architecture Highlights
Hanwha identifies the XRN-3220B4 platform as using a 12th-generation Intel processor architecture. In a surveillance recorder, processing resources are shared across recording services, local decoding, indexing, search, event processing, web access and system management. This is why recorder performance should be understood as a set of simultaneous workload ceilings rather than as a single CPU specification. The design supports up to 520 Mbps transmission bandwidth and up to 200 Mbps playback bandwidth, with simultaneous playback capabilities that vary between local and remote clients. System architects should reserve headroom for playback and administrative activity instead of sizing the recorder exactly to the theoretical incoming maximum.
The storage backplane supports sixteen SATA devices and hot-swap operation. The manufacturer specifies supported HDD capacity up to 10 TB per drive and two RAID arrays, each with up to eight HDDs, for RAID 5 or RAID 6. RAID 5 uses single-parity protection while RAID 6 uses dual parity; RAID 6 therefore sacrifices more raw capacity but tolerates two concurrent disk failures within the array. For sixteen-drive surveillance designs, RAID 6 may be considered where rebuild exposure and large-capacity disks increase operational risk, although the final layout should follow the customer’s resilience requirements, validated drive list and retention target.
Video output architecture includes two HDMI connectors. HDMI 1 supports up to 3840 × 2160 at 30 Hz, while HDMI 2 supports 1920 × 1080 at 60 Hz. Clone and expanded display modes enable operators to present different monitoring layouts across two displays. This can be useful in guard rooms where one screen carries a primary multi-camera matrix while another displays selected incidents, playback or secondary live views. Local display decoding limits must still be respected; recording a high-resolution stream and decoding many high-resolution streams simultaneously are separate operations.
Physical interfaces include three 1 GbE RJ-45 ports, eight alarm inputs, four alarm outputs, one 3.5 mm audio output and four USB ports consisting of two front USB 2.0 and two rear USB 3.0 connections. Network audio is supported across 32 channels with G.711, G.726 and AAC, and two-way audio communication is supported. Alarm I/O can bridge digital surveillance events with physical security infrastructure such as sensors, relay-driven devices or audible indicators, subject to correct electrical design.
The embedded Linux operating environment minimizes dependence on a general-purpose desktop operating system and supports appliance-style administration. Security controls include IP filtering, user-access logging, TLS, 802.1X network authentication, encrypted device certificates rooted in the Hanwha trust chain, signed firmware and TPM. A TPM can protect cryptographic material and support device trust functions, but secure deployment still depends on changing default credentials, applying firmware updates, restricting management access, separating camera traffic where appropriate, synchronizing time, limiting outbound connectivity and monitoring logs.
Thermal and electrical architecture must be respected in rack design. The published operating range is 0°C to 40°C and 20% to 85% relative humidity. Maximum power consumption is approximately 265 W with sixteen HDDs, and the unit accepts 100–240 VAC ±10% at 50/60 Hz. In a UAE equipment room, UPS capacity should account for the recorder, installed drives, network switches, displays and any PoE infrastructure separately because the XRN-3220B4 does not provide an integrated camera PoE switch. Cooling should be calculated for the full rack load, not the recorder alone.

Sizing begins with stream mathematics. For each camera, define the main-stream codec, average bitrate, expected peak bitrate, frame rate, resolution and hours recorded per day. Multiply the aggregate average bitrate by the required retention period, then add RAID overhead, filesystem allowance and practical free-space reserve. Event-only recording can greatly extend retention in low-activity scenes but may be unsuitable where continuous evidential coverage is mandated. Scene complexity also matters: entrances, roads, trees, crowds and low-light noise can increase bitrate relative to quiet indoor scenes. Where AI cameras are used, confirm that desired metadata and search functions are supported by the selected camera firmware and recorder software.
The phrase “up to 160 TB” describes raw non-RAID capacity with sixteen supported 10 TB drives, not guaranteed available video retention. A RAID 6 design, for example, reserves capacity for dual parity within each array. Buyers should also confirm the manufacturer’s current HDD compatibility list rather than assuming any SATA disk is suitable. Surveillance drives are designed for continuous write workloads, but exact models and firmware should still be validated. For projects requiring retention beyond internal storage, iSCSI can extend architecture options, but network throughput, storage latency, failure domains and recovery procedures must be engineered together.
Configuration, Sizing & Deployment Workbench
Model the real stream mix
List every planned camera, its recording resolution, frame rate and codec. Record average and peak bitrates rather than relying on megapixel count. Reserve headroom for future cameras, firmware behavior and scenes that become more complex over time. The 32-channel ceiling and 520 Mbps maximum recording capability should both be respected.
Translate policy into capacity
Define whether the organization needs 7, 30, 60, 90 or more days of footage and whether retention is continuous or event-based. Storage should be calculated from real bitrate assumptions, then adjusted for RAID overhead. Identify footage classes that need export or legal preservation outside the rolling recorder pool.
Select RAID and failover deliberately
Choose RAID 5 or RAID 6 according to availability requirements and usable-capacity trade-offs. Large arrays can take substantial time to rebuild after a failure, so spare-drive policy and monitoring matter. Where recorder outage cannot be tolerated, evaluate N+1 failover and test procedures under realistic network conditions.
Design traffic paths
The recorder includes three 1 GbE interfaces, but the correct topology depends on camera VLANs, client traffic, iSCSI use and management policy. Do not assume every interface should simply be connected to the same broadcast domain. Coordinate switch capacity, uplink oversubscription, multicast policy, NTP and 802.1X requirements.
Define local and remote viewing
Determine whether the recorder will feed two local displays, serve remote investigators, integrate with Wisenet Viewer, SSM or WAVE, or act mostly as a recording backend. Local decoding limits differ by resolution, so design screen layouts around the operator’s real workflow rather than the number of cameras alone.
Validate rack, cooling and power
Confirm rack depth for the 571.1 mm chassis, loaded weight after disks, UPS runtime and air-conditioning capacity. The 0°C to 40°C operating range assumes a controlled technical environment. In Dubai, unconditioned cabinets can exceed safe limits quickly, so thermal planning is mandatory.
A useful procurement worksheet should capture quantity, camera count, camera models, planned resolutions, target frame rates, retention days, recording schedule, desired RAID level, remote-user count, viewing software, local monitor requirement, alarm I/O use, failover requirement, rack location, available UPS capacity and delivery site. If any of these items are unknown, FourTeck can prepare a preliminary configuration with clearly marked assumptions, then refine the bill of materials as project details become available. This approach reduces the risk of buying adequate hardware on paper but discovering during commissioning that usable storage, rack clearance or bandwidth does not match the operational target.
Industry Use Cases & Workload Scenarios
Banking & Finance
Branch and office environments often require reliable continuous recording, controlled investigator access, detailed audit trails and secure network architecture. The recorder’s TLS, access logging, 802.1X, TPM and signed firmware support can align with broader hardening standards, while hot-swap RAID storage supports serviceability. Retention policy should be defined by the organization’s internal requirements and applicable regulations.
Healthcare
Hospitals, clinics and medical campuses may need coverage across entrances, pharmacies, public corridors, loading zones and restricted areas. Thirty-two camera channels can suit departmental or building-level designs. Network segmentation and privacy governance are essential, and video access should be restricted to authorized security personnel according to organizational policy.
Government & Public Sector
Public-sector deployments can benefit from appliance-based recording, high storage density, dual displays and failover support. Procurement teams should validate approved camera models, cybersecurity baselines, required retention, evidence-export procedures and any project-specific certification or tender requirements before purchase.
Logistics & Warehousing
Warehouses combine high-motion scenes, loading bays, perimeter areas and operational investigations. Such environments can generate higher bitrates than quiet offices, making the 520 Mbps recording ceiling and 16-bay storage architecture valuable. AI-camera metadata can further accelerate searches for people or vehicles when compatible models are deployed.
Retail
Retailers can record entrances, checkouts, aisles, stockrooms and service areas while using event and text search workflows where supported. Evidence retrieval speed can matter as much as retention capacity because loss-prevention teams may investigate incidents across multiple cameras and time windows each day.
Education
Schools, universities and training campuses can use a 32-channel recorder for individual buildings, zones or smaller campuses. Dual-monitor viewing can support guard rooms, while mobile and browser access can provide authorized remote visibility. Network isolation, user permissions and privacy procedures should be planned before rollout.
Technical Feature Deep Dive 1: Processing, Throughput & Workload Performance Architecture
Surveillance recorder performance is a pipeline. Cameras encode video, the network transports it, the recorder ingests and writes it, the index tracks time and event metadata, and client sessions later decode or export the stored streams. A weakness anywhere in this chain can create dropped frames, slow playback or reduced operator responsiveness. The XRN-3220B4 is designed around a 12th-generation Intel processor platform and separates several relevant bandwidth figures. Recording can reach 520 Mbps in distributed mode and in supported RAID operating states, while normal non-distributed mode is listed up to 300 Mbps. Playback bandwidth is up to 200 Mbps. These numbers should be treated as engineering boundaries, not targets to be permanently saturated.
A 32-camera deployment averaging 8 Mbps per camera generates 256 Mbps of incoming recording traffic. The same channel count averaging 16 Mbps generates 512 Mbps, leaving minimal room below a 520 Mbps ceiling. This simple example demonstrates why “32 channels” cannot be used as the sole sizing metric. High-resolution cameras often use variable bitrate, and short periods of motion, rain, foliage, headlight glare or visual noise can push stream rates above typical averages. A sound design therefore uses observed or vendor-estimated peak behavior and keeps practical margin.
Decoding is another resource domain. Hanwha publishes local display combinations rather than an unlimited decoding claim. The recorder can display a 32 MP H.265 stream at 15 fps, 12 MP at 30 fps, four 8.3 MP channels at 30 fps, sixteen 1080p channels at 30 fps or thirty-two 720p channels at 30 fps in the documented modes. For a control room, the practical design may therefore use sub-streams for dense multiview and switch to the main stream when an operator opens a camera full-screen. This preserves operator visibility without forcing every tile to decode the highest-quality stream continuously.
Recording modes include normal, dual-stream, continuous or event schedules, pre/post event capture and bookmarks. These choices change both storage usage and investigation behavior. Continuous recording offers complete timelines but consumes more capacity. Event-based recording can extend retention but depends on reliable triggers and may omit context if pre-event and post-event windows are too short. Dual-stream workflows can improve remote viewing or playback efficiency. FourTeck recommends testing representative cameras and scene types when retention or bandwidth margins are narrow rather than assuming a theoretical codec ratio will hold across every location.
Technical Feature Deep Dive 2: Security, Redundancy & System Resilience
An enterprise NVR is both a security system and an IP-connected computing appliance, so its own protection must be part of the project. The XRN-3220B4 includes integrated TPM support, signed firmware, TLS, encrypted device-certificate functionality, IP filtering, 802.1X and user access logs. TPM can provide hardware-backed handling of security material, while signed firmware helps establish that software images originate from an authorized source and have not been modified. TLS protects compatible management and communication sessions in transit. 802.1X can participate in port-based network admission control when the surrounding network is configured accordingly.
None of these controls is sufficient by itself. Administrators should use unique high-strength credentials, disable unnecessary services, restrict management networks, keep firmware current, synchronize time from a trusted NTP source and review user access. Camera networks should be designed so that cameras do not have unrestricted access to corporate systems. Remote viewing should use approved secure paths instead of exposing recorder management directly to the public internet whenever possible. Logs should be incorporated into operational review procedures so that failed logins, configuration changes and service events are noticed rather than merely recorded.
Storage resilience is provided through RAID 5/6 and hot-swap disks. RAID 5 tolerates one failed drive in an array, whereas RAID 6 tolerates two. The trade-off is usable capacity: parity consumes space, and RAID 6 consumes more. Rebuilds also place sustained load on surviving disks. Large-capacity surveillance drives can require long rebuild windows, which makes the risk of a second failure relevant. For critical deployments, buyers should consider RAID 6, proactive health monitoring, compatible spare drives and a documented replacement procedure. The recorder specifies up to 520 Mbps recording even in RAID degrade or rebuild modes, but real-world operational policy should still minimize avoidable stress during degraded states.
N+1 failover extends resilience from disks to recorders. In an N+1 architecture, a standby recorder is available to assume recording responsibilities when a designated primary recorder becomes unavailable, subject to supported design constraints. This requires more than purchasing an extra chassis: network reachability, storage expectations, configuration consistency, failover triggering and recovery processes must all be planned and tested. Organizations should document who responds to a failover, how the failed recorder is repaired, how recording returns to normal and how evidence is handled across the transition.
Technical Feature Deep Dive 3: Remote Management, Telemetry & Infrastructure Integration
The XRN-3220B4 can be administered and viewed through several Hanwha ecosystem tools, including Wisenet Viewer, Wisenet mobile, Webviewer, SSM and WAVE. The platform also supports CGI through SUNAPI for compatible third-party VMS integration. This diversity lets an enterprise choose between direct recorder access, centralized security management and mobile workflows based on scale. A single-site office may rely primarily on local display and browser access, while a multi-site organization may integrate recorders into a larger management platform.
Remote-user limits should be included in the design. Hanwha lists up to three remote search users, ten live unicast users and twenty multicast users, with local and remote simultaneous playback limits documented separately. These figures matter when security, operations, management and investigators all expect concurrent access. Centralized VMS architecture may be preferable where many operators need to view multiple sites, because direct recorder sessions are not intended to become an unlimited enterprise distribution service.
The protocol set includes IPv4, IPv6, TCP/IP, UDP/IP, RTP over UDP and TCP, RTSP, RTCP, NTP, HTTP, DHCP, SMTP, ICMP, IGMP, ARP, DNS, DDNS, UPnP, HTTPS, SNMP, ONVIF Profile S and SUNAPI. From an infrastructure perspective, these are integration surfaces that should be explicitly governed. NTP is critical for evidential timestamp consistency. SNMP can support monitoring where compatible management systems are in use. IGMP and multicast design become relevant when multicast viewing is enabled. HTTPS should be preferred for browser management, while UPnP and automatic port exposure may be restricted by enterprise policy.
Event actions include email, push notifications, PTZ presets, alarm outputs, buzzer, monitor output, FTP, SUNAPI commands and shutdown. This allows the recorder to participate in workflows rather than just store video. An intrusion analytics event might call a PTZ preset, raise an operator display and issue a notification. A physical sensor could trigger recording changes or an alarm output. Such automation should be tested to prevent nuisance events, alert floods or ambiguous operator responses. The most effective surveillance systems pair technical event capability with clear standard operating procedures.
What Buyers Should Check Before Purchase
Recorder selection errors typically appear after installation: insufficient retention, unsupported disks, overloaded recording bandwidth, inadequate rack depth, uncontrolled remote access or monitor layouts that exceed decoding capability. A purchase request should therefore include operational assumptions, not only a model number.
01 / FIT — Configuration Fit & Model Sizing
Confirm the required number of cameras today and over the expected project life. Capture resolution, average bitrate, peak bitrate, codec and frame-rate targets for each camera class. Compare the aggregate against the recorder’s mode-specific bandwidth limits with headroom. Define whether local operators need dense 32-camera grids, frequent multi-channel playback or AI-assisted searches. If the design consistently approaches platform ceilings, consider distributing cameras across more than one recorder rather than engineering a zero-margin system.
02 / MATCH — Compatibility & Environmental Requirements
Check the current supported HDD list, camera interoperability, ONVIF requirements and desired analytics functions. Confirm rack depth, ventilation and working clearance. The recorder is rated for 0°C to 40°C, so UAE deployments require suitable conditioned technical rooms. If iSCSI will be used, validate the target platform and network path. If 802.1X is mandatory, coordinate certificates and network-authentication policy before commissioning.
03 / TERMS — Availability, Delivery & Warranty Terms
Model suffixes, regional stock, drive bundles and warranty terms can vary by supply route. Ask for a written quotation identifying the exact XRN-3220B4/KME unit, included accessories, drive configuration if any, delivery location, lead time and warranty process. Do not assume the recorder ships populated with disks unless the quotation states so. Confirm whether installation, configuration, rack mounting or commissioning services are included or separately quoted.
04 / REQUEST — Quote Preparation Data Needed
For the fastest useful quotation, send FourTeck the model, quantity, camera count, desired HDD capacity, retention days, RAID preference, delivery emirate and required date. Where the cameras are not yet finalized, provide approximate resolutions and whether recording will be continuous or event-driven. Mention failover, iSCSI, dual-monitor or central VMS requirements so the proposal can be checked for architectural completeness rather than priced as an isolated chassis.
UAE Regional Availability & Service Ecosystem
FourTeck supports surveillance procurement across the UAE with model validation, configuration review, quotation coordination and delivery planning. Availability can change with distributor inventory, regional allocation and project quantity, so current lead time should be confirmed at quotation stage. For the XRN-3220B4/KME, procurement conversations should also cover compatible surveillance HDDs, RAID design, camera count, rack environment and any requirement for local displays, external iSCSI storage or failover.
K1. Dubai Supply & Logistics Support
Dubai customers can request supply coordination for corporate offices, warehouses, retail facilities, hospitality environments, campuses, data rooms and Free Zone projects. FourTeck can help validate the exact recorder model, proposed disk population and basic network assumptions before quotation.

A clear bill of materials helps prevent drive-capacity or mounting issues during commissioning.
K4. Ajman & Surrounding Emirates Logistics Coverage
Ajman buyers can request hardware availability checks, project quotations and pre-sales guidance for new installations or recorder refresh projects. When replacing an older NVR, provide the existing camera models, codecs and desired retention so compatibility and capacity can be reviewed. Delivery can be coordinated to the customer, integrator or designated project location according to quotation terms.
GCC & Pan-African Supply Chain Reach
FourTeck can coordinate regional project inquiries beyond the UAE, including export quotation support, configuration validation and commercial documentation appropriate to the transaction. Cross-border supply depends on destination requirements, freight route, customs procedures and current product availability. Buyers should share destination city, quantity, required delivery window and whether HDDs or other accessories are part of the shipment.
L1. Saudi Arabia (KSA) Export & Supply Support
Saudi Arabian enterprise and integrator inquiries can be routed for model verification, storage sizing and project quotation support. Large surveillance projects should identify phased quantities, required retention and any approved-vendor or submittal requirements before commercial finalization.
L2. Qatar Market Supply Reach
Qatar buyers can request cross-border sourcing and quotation coordination for XRN-3220B4/KME deployments. Delivery terms, customs responsibility and product configuration should be stated clearly in the commercial offer, particularly where drives and accessories are supplied as a project bundle.

Related FourTeck Products & Compatible Alternatives
| Model | Positioning | When to Consider |
|---|---|---|
| Hanwha Vision XRN-3210B4 | 32-channel NVR with sixteen SATA bays and RAID 5/6, but lower recording bandwidth than the XRN-3220B4. | Consider where camera count is similar but aggregate recording throughput is comfortably lower and the commercial difference is meaningful. |
| Hanwha Vision XRN-3210RB2 | 32-channel recorder with eight SATA bays and RAID support. | Consider for projects needing fewer internal drives or shorter retention while still requiring a 32-channel architecture. |
| Hanwha Vision XRN-3210B2 | 32-channel recorder with eight SATA bays, aimed at less storage-dense designs. | Useful when capacity and redundancy requirements are modest and the project does not need the XRN-3220B4’s higher-performance profile. |
| Hanwha Vision XRN-6420B4 | Higher-channel-count platform in the same enterprise recorder family. | Consider where a single site exceeds 32 cameras or consolidation into fewer recorders is operationally preferred. Confirm exact current specifications before substitution. |
Alternative selection should be based on aggregate bitrate, internal storage requirement, RAID policy, failover strategy and operator workload rather than model hierarchy alone. A smaller recorder may be a better architectural choice when cameras are distributed across buildings or network zones, while a higher-channel model can simplify centralized sites. FourTeck can compare current Hanwha Vision options against the project camera schedule and retention requirements so that the selected recorder matches both technical needs and commercial constraints. Model availability and exact specifications can change over time, so alternatives should be revalidated at quotation stage.
Why Enterprises Choose FourTeck
Enterprise surveillance procurement benefits from technical validation before purchase. FourTeck’s role is to help buyers translate a model request into a coherent commercial configuration by checking camera count, storage expectations, drive population, delivery location and integration requirements. This reduces ambiguity in quotations and helps project teams compare like-for-like offers. Where a requirement is configuration dependent, the quotation can state assumptions instead of presenting uncertain details as fixed facts.
For the XRN-3220B4/KME, FourTeck can assist with supported-drive selection guidance, retention discussions, RAID planning, rack and power considerations, network assumptions and accessory coordination. Quote turnaround depends on project complexity and supplier confirmation, while delivery dates depend on stock and logistics conditions. Warranty support is handled according to the supplied product’s applicable terms, and buyers should retain serial numbers, invoices and project documentation for efficient service handling.
This evidence-led procurement approach is particularly useful for integrators and corporate IT teams that need defensible technical submittals. The objective is not merely to ship a recorder, but to reduce the chance that the installed system fails to meet recording, retention or operational expectations because key design inputs were never captured during procurement.
Frequently Asked Questions
1. How many cameras does the Hanwha Vision XRN-3220B4/KME support?
The XRN-3220B4 supports up to 32 network-camera channels. Camera support spans resolutions from CIF up to 32 MP. The practical design must also stay within recording-bandwidth and local-decoding limits, so a 32-camera deployment should be sized using actual codec, frame-rate and bitrate assumptions rather than channel count alone.
2. What is the maximum recording bandwidth?
Hanwha specifies up to 520 Mbps recording bandwidth in distributed mode and in supported RAID normal, degraded and rebuild conditions, while normal non-distributed mode is listed up to 300 Mbps. A production design should maintain operational headroom below the applicable limit to accommodate variable bitrate peaks, playback activity and future camera changes.
3. How much internal storage can the XRN-3220B4 hold?
The recorder has sixteen hot-swap SATA bays and supports up to 10 TB per validated drive, giving up to 160 TB raw non-RAID capacity. Usable video capacity is lower when RAID is enabled and also depends on filesystem overhead. Buyers should confirm the current Hanwha HDD compatibility list before selecting drives.
4. Does the recorder support RAID?
Yes. The XRN-3220B4 supports RAID 5 and RAID 6, with the manufacturer documenting two arrays of up to eight disks each. RAID 5 offers single-parity protection and RAID 6 offers dual parity. The correct choice depends on the project’s usable-capacity target, disk-failure tolerance and operational recovery policy.
5. Can the XRN-3220B4 use external storage?
Yes. iSCSI storage is supported. External storage should be treated as part of the system architecture rather than a plug-and-play capacity extension. Network throughput, storage latency, failure behavior, switch design and supported configuration all need to be validated before deployment, especially when recording continuity is critical.
6. What cybersecurity features are built into the recorder?
Published security capabilities include IP address filtering, user-access logging, 802.1X, TLS, encrypted device certificates, signed firmware and integrated TPM support. These features strengthen device security, but enterprises should still implement network segmentation, strong credentials, firmware management, trusted time synchronization, least-privilege access and controlled remote connectivity.
7. Does it support recorder failover?
Yes. N+1 failover is supported. A complete failover design requires a compatible standby architecture, network reachability, configuration planning and operational testing. Buyers should define what happens during a recorder failure, how recording responsibility transfers and how the system returns to normal after repair rather than relying on the feature name alone.
8. What local monitor outputs are available?
The recorder provides two HDMI outputs. HDMI 1 supports up to 3840 × 2160 at 30 Hz and HDMI 2 supports 1920 × 1080 at 60 Hz. Clone and expanded layouts are available. Maximum simultaneous decoding depends on the resolution and frame rate of displayed streams, so guard-room layouts should be planned accordingly.
9. Is AI search available on this NVR?
The XRN-3220B4 supports AI search functions when used with compatible Hanwha AI cameras that provide the required object attributes and metadata. Exact search capabilities depend on camera model, firmware, recorder software and system configuration. Buyers should identify the desired analytics workflow and validate camera-to-recorder compatibility before procurement.
10. How can I get a Dubai quotation for XRN-3220B4/KME?
Send FourTeck the required recorder quantity, delivery location, camera count, desired retention period, planned HDD capacity or RAID preference, and target deployment date. If the camera schedule is available, include camera models and expected bitrates. FourTeck can then coordinate current availability, configuration assumptions, delivery terms and applicable warranty information in the commercial proposal.
Request a Hanwha XRN-3220B4/KME Procurement Quote
For an accurate proposal, provide the model and quantity, number of cameras, desired HDD capacity or retention days, RAID preference, delivery location and deployment timeframe. Add any requirement for N+1 failover, iSCSI storage, dual displays, Wisenet Viewer, SSM, WAVE integration or alarm I/O. FourTeck can use these inputs to validate the requested configuration and coordinate a Dubai or UAE commercial quotation.
