Bandwidth

The maximum data stream in Mbit/s that the NVR is capable of processing when recording and displaying. The throughput parameter is specified as the maximum incoming/outgoing speed, or as the sum of incoming and outgoing streams (total throughput). It is calculated in such a way that the throughput exceeds the total flow of all IP cameras connected to the DVR, and another 25–30% is put in reserve for playing video or viewing it via network access.

Max. resolution (IP)

The maximum supported resolution of IP cameras with which the NVR is technically capable of working (primarily recording). With rare exceptions, devices record in maximum resolution from all connected IP cameras. However, the limiting factor here is bandwidth (see the relevant paragraph) – depending on the shooting conditions, it may not be enough.

High resolution allows you to get a more detailed image in which fine details are better visible. On the other hand, such videos take up large amounts of disk space, and their support significantly affects the cost of the device.

CMS

Recorder compatibility with CMS tools.

CMS is a set of software designed to manage the recorder from a PC. At the same time, the capabilities of this software include not only work with one device, but also the creation of a single video surveillance system from several registrars — so that control and data output from them is carried out through one computer. Anyway, the use of CMS can greatly simplify the work with the registrar.
