Specifcations: Length: 69MM Width: 48MM Air Pressure Wireless Intruder Alarm Around 1 in 50 households were victims of domestic burglary last year in the UK. It's impossible to completely eliminate the chances of it happening to you, but there are some measures you can take to deter burglars from targeting your home. One form of deterrent is our Portable Air Pressure Alarm, it's a high tech security device that constantly monitors the air pressure inside any closed space up to 1000 square feet. If the worst was to occur and an intruder opens a door or window causing the air pressure to change, an alarm will sound. Once the compact alarm is set, you can continue to freely move within your home as the movement of pets and people don't set off the alarm. It can be used in homes, business, hotels or within your dorm. There are three sensitivity settings available, high, medium and low.
