The pad is pressure-sensitive, and will sound an alarm when it is stepped on. It features three different chimes, and can be set for up to 120db. Installation is a snap...just lay it down at your door. You can place any existing doormat or carpet overtop of it and it'll still work just fine, so you can keep your decor how you want it without having to make aesthetic concessions to security. It has a weatherproof Ip45 rating, up to a 100-foot range, and includes a 12v battery for the mat as well as a battery-operated remote to control on/off and which mode you want to use. The mat measures 2.8 x 9.4 x 11.4 inches and weighs just one pound.
This is supposed to be available at the end of this month, for right around $27.00 US.
