Q5. The NVR will not hold the maximum number of IP cameras?
Take the 16 CH NVR as an example. Some 16 CH NVR support a maximum of 120Mbps
bandwidth input. Refer to the picture below. The remaining bandwidth should be larger than
the bandwidth of the IP camera you want to add, or it would fail to add the IP camera. You
should lower the added cameras' bitrate to release the bandwidth. It is recommended to add
cameras by "Quickly Add" for batch adding.
