I had installed a surveillance camera in my home in a village in India. I have also paid and obtained a static ip address for the same. The camera was working fine for two years and I could pan and tilt by using Guarding Expert application on ios and android devices. The Service Provider has changed and this new service provider is saying that Port 8000 is not required. We are unable to get the camera working. Earlier it was working fine with Cisco router EA 6200. We also tried with CP Link router on the Service Provider's recommendations. But still the camera is not working. Kindly provide guidance to get this camera working.
