RTP (Real-time Transfer Protocol) is a standardized packet format for delivering real-time
audio and video data of the IP cameras on the Internet. The real-time data transfer is
monitored and controlled by RTP (also RTCP). The default setting is 6100–6299. If the IP
cameras use different RTP ports, enable ‘Specify RTP port range’ and specify the port
numbers.
Note: Make sure the ports have been opened on the router or firewall to ensure normal
monitoring and recording.
