HIK VISION 32 Camera NVR Unit With POE (Power Over Ethernet) Built In A Network Video Recorder For Up To 32 IP Cameras Only. With this Network Video Recorder, (or NVR for short) you can record and play the video and audio signal from up to 32 IP-based network cameras at up to 5MP per camera giving simply fantastic quality of image. Up to 200Mbps shared camera bandwidth, (incoming) and 160Mbps outgoing for smooth playback. A Gigabit Ethernet LAN port is fitted for the additional 16 cameras to be connected, (Please note, a POE switch will be required to do this) and this LAN port will also carry the data to the rest of the network and to the router. As this recorder has a POE switch built in to both power the cameras and handle the data streams from the cameras with a minimum of cable running, this will make for a tidy installation and also allow your network to keep traffic off of the router, this reduction to network data traffic on your main network will not impact on your network bandwidth or speed. As this will be a secure network, within a network in effect, (Cameras IP Range set from the NVR will be diffrent from your LAN IP range) so nobody will be able to access your cameras directly unless they have the login information of the NVR, so in terms of security this is very safe - no NVR password = no camera access. Due to a large number of pixels on a picture, (video stream from the cameras) digital zoom is now a truly viable option, this allows you to zoom in on an area of the picture during recording and playback whilst still recording the entire image giving an obvious advantage over optical zoom cameras that will see a smaller and smaller area the more you zoom in. Furthermore, you can transfer video and audio to an external device, which can be monitored by a remote PC or on a local monitor in full HD if required. This recorder supports ONVIF cameras and selected 360 degree fish eye hemispheric cameras also.
