You just installed a security camera that is connected to your SOHO router and communicates on port 4150. You can't see the video stream from your computer or another computer after setting up the camera. What did you forget to do?

Since the camera uses port 4150 for communication, the port needs to be open and port forwarding needs to be set up so that your remote connection can reach the camera by using that port via the router. You can access the camera's video stream from a computer connected to the same router, which proves that the camera is connected properly to the router. Since the firewall is an essential component of the security of your network, disabling it is not a good idea.
