Hello all...I am in the process of finalizing a nice little CCTV security system. I have 6 cameras and in addition to that, I have installed 3 motion sensors that plug into my Alarm Inputs in my DVR. Question...I can disarm the Alarm in my DVR menu, but I was wondering if there is a Keypad, similar to a Security Keypad, that I could wire in that I could disarm the sensors instead of having to go to my DVR each time?
