Qolsys Wireless Door Window Sensor:

The Qolsys Wireless Door Window Sensor is a powerfully small door/window sensor that can be placed almost anywhere. It is made to work with the Qolsys IQ Panel. It also works with all 319.5MHz Wireless Security Systems.

The sensor also comes in white or brown color and it’s easy to install. You just need to enter the installation menu and click on add a sensor and then trip the sensor once or twice. The Qolsys panel will then pick up on it and ask you if you want to add it. So installation is a breeze.
