AI That Finds What Matters

This NVR uses AcuSense technology to separate people and vehicles from false alarms. Motion Detection 2.0 filters out leaves, rain, and shadows so you only get alerts that matter. Face detection lets you search recordings by face picture and instantly locate a specific person across all connected cameras.

Record 32 Cameras in 4K Clarity

Handle up to 32 IP cameras simultaneously with 256 Mbps incoming bandwidth. The unit records in resolutions up to 12MP, so you capture license plates and facial details with sharp clarity. Smart H.265+ compression reduces storage requirements by up to 75% compared to standard H.264, letting you keep more footage on the same drives.

Built for Installers and IT Managers

The 1.5U chassis fits neatly into standard server racks or equipment rooms. Dual Gigabit Ethernet ports allow for camera traffic separation or link aggregation. HDMI output delivers 4K resolution to your monitor, and the unit supports 16-channel simultaneous playback for quick forensic review.

Expandable Storage That Scales With You

Four SATA bays accept drives up to 16TB each, giving you a maximum of 64TB on-board storage. That is enough for weeks of continuous recording across a full 32-camera deployment. Add or swap drives without special tools, and manage recording schedules per camera to balance retention with storage capacity.
