I'm not sure if anyone else has this problem but I've recently bought 4 of ip2m-841b wireless cameras only to find that when enabling the microphone feature of the camera that I don't hear any sounds coming from my camera. On one of the cameras the microphone works but the other 3 don't. I can here the sounds coming from the camera though just that the talkback doesn't work.
Does anyone else have this problem? Do I have a defective product? Thanks for any replies.
