What network ports does NVR software use and for what purpose (in case of firewall)? Can I change them?
There are mainly two ports NVR software will use:
- NVR communication port: defaults to 3557.
- Built-in web server port: default to 8086.
How to change ports
Open the system configuration dialog box.
Default built-in web server listen port is 8086. If you configure the listen port to zero ("0"), the web server will be turned off.
Please be noted that to make the remote live video web viewing, you are required to properly configure your firewall, if any. Two ports are needed. One is web server port, the other is NVR communication port, which defaults to 3557.
