Geovision 84-SNR0412-001U 4CH 4K PoE NVR
Overview
The Geovision 84-SNR0412-001U is a 4-channel standalone network video recorder engineered for small to mid-sized security deployments. This unit handles 4K (8MP) IP camera streams natively, recording and storing video locally without requiring external servers or VMS software. It runs as a standalone appliance—power it on, connect your network cameras, and begin recording. The combination of compact footprint and local storage makes it suitable for retail locations, small offices, and distributed branch sites where you need reliable video retention without cloud dependency.
Compatibility
The 84-SNR0412-001U accepts any ONVIF-compliant IP camera over standard Ethernet. The unit integrates seamlessly with IP cameras in your existing network, including PTZ and fixed-position models. Verify your camera model supports ONVIF Profile S or T for optimal playback and remote access; most current commercial IP cameras do. Four channels allow you to record from four simultaneous camera streams at full 4K resolution without frame-rate reduction.
Installation Notes
Connect the NVR to your network switch or PoE-enabled network infrastructure using standard Cat5e or Cat6 cabling. The PoE power support (802.3af) means compatible cameras can draw power directly from the same Ethernet cable, eliminating separate power runs for each camera—a labor and cost reduction during initial wiring. Ensure your network switch can deliver sufficient PoE budget for the total camera draw (verify wattage per camera against your switch's available PoE capacity). No external power supply is required for the recorder itself; it connects to standard AC mains. Mount the unit in a secure cabinet or on a shelf away from high-traffic areas to protect storage and network connections.
Video Encoding and Storage Strategy
The recorder supports both H.265 and H.264 compression. H.265 cuts storage consumption roughly in half compared to H.264 for equivalent quality—a meaningful savings when recording four 4K streams continuously. Configure your cameras to stream H.265 if they support it; fall back to H.264 for older models. Local hard-drive storage (expandable via internal bays) retains video on-site, ensuring no dependency on internet bandwidth or cloud subscription costs.
