Hi, I have a security system installed in my house. I would like to connect 2 or 3 wireless cameras to it so that I can get the entire view of the house. I believe connecting cameras would allow me to record videos and monitor my house from any part of the world. Is it possible to connect multiple cameras to an existing home security system? Is there any other requirements or specifications to connect the cameras? Pls post your replies. Thanks in advance!!
