USED LIKE NEW Xfinity Home Security System with 3 Cameras & More! Description: This Xfinity Home Security system has served us well over the last few years. This system includes: 3 home security cameras (two are XCams and one is an XCam2), 3 window/door sesnors, a wireless keypad, a motion sensor, and all the wall fixings to make it snug against the wall. The Xcam2 is a camera in which you can talk into it and talk to others on the other end and vice cersa. The Xcams are for monitoring. We were using this entire system until a few days ago. They all work excellent in dark/night settings. From a smoke-free and pet-free home.
