I have probably what you are looking for. Don't know if there is a store in your area but the one I used is called 25/7 Protections
http://www.257protection.com. The interface between DVR-Router-phone is through IC-Realtime, and a gmail account for receiving text messages about alerts from the motion detectors around the house. I can pull up all my cameras, take still photos from afar, and operate the alarm system remotely from the phone. With a little more money you can add a speaker or microphone to speak or listen from your phone.
