Scout’s door panels have more functions than Scout’s door sensors. Both devices are basically contact sensors. The sensor itself is attached to the door or the door frame and a magnet is attached to the opposite side. When the magnet moves, the sensor sends you an alert. However, the Scout door panel also features a siren and an RFID scanner for keyless entry to your home. Typically, you would install a door panel at your home’s main entrance and install access sensors on other doors and windows throughout the house.
