Recorders (NVR)

What is an NVR recorder?

An NVR is a Network Video Recorder , a video recorder for IP cameras . While with a DVR/XVR recorder the video signal is transmitted analogically from the camera to the recorder, and the recorder is responsible for encoding the video, with an NVR the encoding work is done by the camera, the signal is transmitted over an IP network, and the NVR stores the data on a hard drive.

What should I take into account when choosing an NVR recorder?

Manufacturer: Each manufacturer uses its own software to access the equipment from mobile, tablet, and computer. Often when you get used to a platform the ideal is not to change, and if we have several teams it is interesting that they all work under the same platform. The HiWatch and Safire devices are manufactured by Hikvision , and the X-Security devices are manufactured by Dahua , so they share a platform.

Channels: It is the maximum number of IP cameras that a device supports, how many cameras can be connected to it.

Maximum resolution: Indicates the maximum resolution of the IP cameras that we can connect to the recorder.

Bandwidth: The input and output bandwidth puts a limit on the bitrate of the cameras with which we will work, and the maximum number of simultaneous remote connections that the equipment will support.

POE ports: The POE network ports on an NVR recorder facilitate installation, since the NVR itself will power the cameras through the network cable, and if we use IP cameras from the same manufacturer as the equipment, the connection will be "plug and play".

What advantages does an NVR offer?

Among the advantages of using an NVR with IP cameras we can highlight the recording of remote cameras (cameras in several businesses with a recorder in central offices), the use of Wi-Fi IP cameras (for places that are difficult to wire, such as an elevator), or perform redundant recording in a simple way (duplicate recordings on two or more NVR recorders simultaneously).
