Generally, there is no need to make any settings for our cameras to access the home firewall. However, if your firewall level is extremely high and the network environment is very strict such as in a Bank, in Military and in government facilities, it is usually hard for the camera to access through the firewalls, not only for our cameras, all other cameras.
Our IP Camera is able to use the following ports. Please check these ports with your router for troubleshooting.
Also, the RTSP protocol for the camera is rtsp://ipaddr:554/onvif1 , the ipaddr is the ip address of the camera.
