5.3.4 Protocol Management
To assign a specific port for accessing NVR via the web browser, please enable the
option “Specify HTTP port number” and enter the port number. The default setting is
80.
RTP (Real-time Transfer Protocol) is a standardized packet format for delivering
real-time audio and video data of network cameras over the Internet. The real-time
data transfer is monitored and controlled by RTP (also RTCP). The default setting is
6100-6199. If your network cameras use different RTP ports, please enable “Specify
RTP port range” and enter the port numbers.
Note: Make sure you have opened the ports you set on the router or firewall to
ensure normal monitoring and recording.
