It is recommended that you change the default ports to custom/non-standard ports on your LILIN equipment before doing any port forwarding.
A basic guide for keeping your CCTV system safe online can be found here
The default ports that are required to be opened in the firewall to allow external connections are:
RTSP: 554 (Optional & not needed in most cases)
If you want to remotely connect to more than one IP camera you will need to change the HTTP ports used so each IP camera is using a unique HTTP port
Camera 1 - HTTP Port: 80
Camera 2 - HTTP Port: 81
Camera 3 - HTTP Port: 82
Please note changing the HTTP port from its default port 80 will change the URL you will need to enter when connecting to the camera. The new URL will need to follow the structure shown below:
http://<IP ADDRESS>:<PORT> E.G http://192.168.0.200:81
Failure to insure you add the http:// and the :<port> at the end of the URL may result in you not being able to connect to the camera, depending on which web browser you are using. If this is the case, we recommend you download and install LILIN's IPScan. This is available here.
