Manufactured by Hikvision, one of the world’s leading CCTV product manufacturers, the DS-7608NI-SP offers up to 40MB/sec bandwidth capability allowing it to record up to 4x 3MP cameras at 25 FPS. It has a 4 port in-built PoE switch allowing up to 4 channels to be connected directly to the back of the NVR. It is compatible with our Hikvision cameras as well as many other ONIF compliant brands giving true plug and play functionality. This model has programmable recording recording resolutions (up to 5MP) and frame rates allowing each camera to be configured individually. Outputs include HDMI and VGA along with a composite connector. The NVRs setup wizard automatically configures the system to monitor all cameras, recording to its hard drive when it detects movement. We include a 2TB hard drive which will give around 3 weeks recording time under normal use conditions (then it will start to over-write the oldest data).
