free home security systems
Components are easy to move around without damaging your walls, and you can take the system with you to your next home, which is a welcome feature. The keypad, also available in black or white and powered by four standard AA batteries, sees the biggest
design improvement, with a 2. 5 inch LCD replacing a tiny monochrome screen. Nicely sized, round backlit rubber buttons replace
the tiny oval ones on the old keypad. A proximity sensor is a nice touch, illuminating the keypad for nighttime use. The larger screen also makes the system setup process much easier, since you just pair all the components using easy step through menus on the display.
