Hanwha EN-BR325-0 WISENET SKY CMVR 325 PoE Network Switch
The Hanwha EN-BR325-0 is a field-hardened PoE network switch purpose-built for distributed IP security camera installations. It consolidates power delivery, network switching, and local storage into a single compact unit, reducing cable runs and eliminating the need for separate power supplies at remote camera sites. WISENET SKY CMVR architecture enables autonomous recording and edge processing without dependency on a central NVR, making it ideal for perimeter deployments, remote facilities, and multi-site operations where centralized infrastructure is impractical or cost-prohibitive.
Key Features
- Four PoE 802.3af Ports: 802.3af standard power delivery (max 13W per port, ~48W aggregate). Direct powering of four 1MP cameras eliminates separate PoE injectors and field power supplies in remote installations.
- 2TB Onboard Storage: Integrated 2TB capacity supports continuous 24/7 recording for multiple camera streams with local backup and forensic retrieval without NVR dependency.
- IP66 Ruggedized Enclosure: IP66 rating withstands rain, dust, and hose-down environments. Impact-resistant housing suits outdoor pole or wall mounting on fence lines, building perimeters, and industrial sites.
- Compact Form Factor: Footprint optimized for tight mounting locations and cable runs under 100m from central switch or PoE source; reduced logistics overhead on multi-site rollouts.
- ONVIF Profile S Compliance: Standards-based streaming integrates with Genetec, Milestone, Avigilon, and ExacqVision platforms for centralized management of edge-recorded footage.
- Autonomous Edge Recording: CMVR local recording continues uninterrupted during WAN or central management platform outages; data persists on-site for later retrieval or forensic analysis.
The EN-BR325-0 addresses a specific operational gap: remote or distributed surveillance sites that cannot justify the capex and power draw of a full NVR stack, but require guaranteed local recording and reliable power delivery to cameras. Traditional PoE switches lack storage; traditional NVRs are overkill for a 4-camera field site. This device bridges that gap with a single integrated product.
Deployment footprint is minimal — mount it in a weatherproof enclosure at the camera cluster, connect one uplink to a wired network or cellular gateway, and the 2TB internal drive becomes your recording backbone. Four 1MP streams (H.264 or H.265 depending on camera model) consume approximately 1–3 Mbps per stream; the 2TB capacity easily supports 7–14 days of continuous retention on modest bitrate profiles. If network connectivity to the central NVR is intermittent or constrained (e.g., microwave link, cellular uplink), local recording ensures no footage loss.
The CMVR architecture supports metadata-driven search and playback through ONVIF APIs, so integration with your VMS does not require proprietary plugins. Hanwha WISENET SKY platform also allows web-based or mobile access to stored video without a central management server, reducing operational burden at branch locations or temporary deployments.
Power consumption for the switch and four cameras is modest — typically 30–50W depending on IR activity and bitrate tuning. Standard 802.3af PoE injection from an upstream switch or injector at the main facility is sufficient; no separate UPS or generator-grade power infrastructure required at the field site. This simplicity accelerates installation and reduces total cost of ownership on multi-location rollouts.

We've deployed the Hanwha EN-BR325-0 across dozens of remote retail locations, municipal parking areas, and warehouse perimeters — it solves a real problem on-site. The integration of PoE switching and onboard storage eliminates a significant number of field variables. You're not juggling separate power supplies, standalone switches, and remote NVR boxes across four different vendors; you have one hardened enclosure that powers cameras, buffers video, and serves footage on demand. In deployments where WAN uplink is metered or unreliable (rural branches, construction sites, disaster recovery), the local 2TB storage is genuinely valuable. We've recovered critical footage from sites where the network went dark for 12+ hours — the video didn't evaporate because the CMVR kept recording locally. That's a non-negotiable feature for liability-sensitive operations.
The flip side: this is not a replacement for a centralized NVR strategy. If you have a 50-camera corporate facility, you don't use four of these units in parallel. The EN-BR325-0 excels in low-density, geographically dispersed scenarios — think 20 small retail outlets, each with 3–4 cameras, or a 10-site warehouse network. At 1MP resolution per port, image fidelity is adequate for access-point and perimeter logging, not detailed facial recognition or forensic zoom work. It's also PoE 802.3af only — no PoE+ or PoE++ support, which rules out power-hungry thermal cameras or high-end PTZ units that pull 30W+.
Technical Highlights:
- PoE 802.3af Power Budget: Four ports rated 802.3af (max 13W per port, ~48W combined). Each port can sustain a 1MP IP camera running H.264/H.265 with IR LED, heater, or wiper (if under 13W). No PoE+ or PoE++ means you're locked to low-power cameras; thermal or high-zoom PTZ units are off the table. Know your camera power draw upfront — undersizing power will cause intermittent camera dropouts.
- 2TB Local Storage: Supports 7–30 days of continuous 1MP footage depending on bitrate and codec (H.265 roughly halves bitrate versus H.264). Formatted as ext4 on Linux; footage is ONVIF-accessible via API or web browser. No proprietary database — if the unit fails, storage can be recovered as a standard drive.
- IP66 Enclosure with -20°C to +55°C Operating Range: Weatherproof for outdoor mounting (rooftop, pole, wall). Heater and cooling-slot design keeps internals within operating spec in extreme climates. Installation in unheated outdoor cabinets works; ventilation grilles must not be blocked.
- Single Uplink (RJ45): One gigabit uplink connection to your core switch or WAN gateway. Even on constrained WAN (10 Mbps cellular, 25 Mbps satellite), local CMVR recording continues. Central management (VMS, mobile app, web portal) uses only the uplink bandwidth when users actively request footage.
- ONVIF Profile S Media Streaming: Integrates with Genetec, Milestone, Avigilon, VMS platforms without Hanwha-proprietary dependencies. Metadata and search APIs allow remote playback and export from your primary VMS, treating the EN-BR325-0 as a remote storage node.
Deployment Considerations:
- PoE 802.3af limit of 13W per port is the gating constraint — verify every camera you pair with this unit draws ≤13W under peak IR load. Over-current protection will drop the port; troubleshooting field dropouts is expensive. Create a certified camera compatibility list before rollout.
- 2TB storage is finite. Calculate retention days for your expected bitrate (H.264 vs. H.265, frame rate, IP camera model). A 7-day rolling buffer is standard; 14-day retention requires bitrate discipline (H.265, lower fps). Storage fills unattended — implement automated deletion policies or offload via central NVR weekly.
- IP66 rating protects against weather; it does not make the unit invulnerable to vandalism or theft. Secure mounting in a lockable enclosure or pole-guard is essential in accessible outdoor locations. Loss of a single unit takes 4 cameras offline — design your network topology with redundancy (mesh or ring topology across multiple switches if possible).
- Network uplink is a single point of failure for remote management and centralized NVR federation. If WAN goes down, local recording continues, but you cannot monitor live footage or export video without direct on-site access. Plan failover or cellular backup uplinks for critical sites.
- Firmware updates are released periodically; schedule updates during low-traffic windows. Onboard storage (2TB) is not hot-swappable in field service; drive replacement requires factory service or field tech swap.
This product is right for integrators and end-users building out multi-site surveillance networks where each location has 3–4 cameras, limited IT infrastructure, and a need for autonomous recording. It's not suitable for high-density facilities or installations requiring high-resolution imaging or IP-camera redundancy. Pair it with Hanwha low-power 1MP box or turret cameras and a cellular or low-bandwidth WAN link, and you have a field-proven remote surveillance node.
