Scale Up to 32 Cameras on One NVR

This 32-channel NVR handles a full security setup without breaking a sweat. Connect up to 32 IP cameras simultaneously and manage them from one interface. The built-in 16-port PoE switch powers cameras directly — no separate switch, no extra cabling, no added cost. Ideal for small businesses, warehouses, and multi-zone residential properties.

AI That Finds What Matters

AcuSense technology brings smart AI to 4 channels. Face detection lets you instantly locate a person in hours of footage. Virtual tripwire and intrusion detection trigger alerts only when someone crosses a defined boundary — not when a leaf blows by. Motion Detection 2.0 filters out false alarms from animals, rain, and shadows, so you review less and act faster.

4K Recording with 75% Less Storage

Record in ultra-high 12MP resolution and see every license plate and face clearly. Smart H.265+ compression cuts storage usage by up to 75% compared to H.264, so your 64TB of HDD space goes further. Four bays give you room to expand — up to 16TB per drive. That means weeks of continuous footage without constant drive swaps.

Plug-and-Play with Any ONVIF Camera

This NVR is not locked to one brand. It works with any ONVIF-compliant IP camera, so you can mix and match hardware based on budget and coverage needs. The 1.5U form factor fits standard server racks, and the 100-240V power supply handles any US outlet. Set it up, add cameras, and start recording in minutes.
