specifications for standards). Refer to the picture below. The remaining bandwidth should be larger than the bandwidth of the IP camera you want
to add, or you will fail to add the IP camera. You should lower the added cameras' bitrate to lower the bandwidth. It is recommended to add
cameras using "Quickly Add" for batch adding.
