Q5.
The DVR cannot add up to the maximum number of IP cameras?
Take the 4 CH DVR as an example. Refer to the picture below. The remaining bandwidth
should be larger than the bandwidth of the IP camera you want to add, or you 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.
