Choose countryThe NVR4232-4KS3 is a network video recorder for 32 IP camera channels, supporting resolutions up to 12 MP. It offers a local graphical interface and web operation, with mobile access from iOS and Android devices.
Analytics and recording
Recorder-based SMD Plus operates on 4 channels, using secondary human and motor vehicle filtering to reduce false alarms caused by leaves, rain and lighting changes. Camera-based face detection, face recognition, perimeter protection and SMD Plus are each specified for 6 channels. These camera-based functions depend on the connected cameras' capabilities.
- Video output: HDMI up to 3840 × 2160 in simultaneous output mode, plus a separate VGA port.
- Playback: up to 16 channels, including event and tag playback.
- Storage: 2 SATA ports, supporting up to 20 TB per disk; this limit varies with ambient temperature.
- Backup: to a USB device or over the network.
Connections and performance
Connections include Gigabit Ethernet, RCA audio input and output, 4 alarm inputs and 2 alarm outputs. With AI enabled, incoming and recording bandwidth are each 80 Mbps; with AI disabled, they are 160 Mbps and 128 Mbps respectively. Power requirements are 12 VDC, 4 A.
