UNIVIEW NVR302-32S — 32-Channel 2-HDD Network Video Recorder
Built for Large-Scale IP Surveillance
Take control of large-scale IP surveillance with the UNIVIEW NVR302-32S, a professional 32-channel network video recorder built for demanding security installations.
Efficient, High-Capacity Recording
- 32 IP camera channels
- Up to 8MP recording
- Ultra265/H.265/H.264 compression — reduces storage and bandwidth needs
Broad Camera Compatibility
The recorder supports mainstream third-party IP cameras through ONVIF Profile S, Profile G, and Profile T, as well as RTSP protocols.
Substantial Storage
Two SATA hard-drive interfaces support up to 8TB per HDD, giving larger CCTV deployments plenty of room to store footage.
Flexible Viewing and Connectivity
- HDMI and VGA simultaneous video output
- Two Gigabit Ethernet ports
- USB connectivity
- ANR technology — keeps recording reliable if network connectivity drops
Smart, Scalable Monitoring
- Up to 16-channel synchronous playback (per the current datasheet)
- Intelligent camera-side VCA functions
- People-counting capabilities
- Smart Intrusion Prevention
Together, these make the NVR302-32S well suited to offices, retail stores, warehouses, schools, hotels, factories, and other multi-camera security installations.
