The cellular radio is also used to push updates to the system. For example, the $229 SimpliSafe Foundation is a starter kit that gives you the hub, a door/window sensor, a motion sensor, and a yard sign. Additional door/window sensors go for $14. 99 each and you can order glass break detectors for $34. 99 each, smoke detectors for $29. 99 each, and water sensors for $19. 99 each. The LifeShield Essentials system goes for $199. 99 and comes with a base station, a keypad, a keychain fob, four door/window sensors, a motion sensor, a fire safety sensor, and an Asus Memo Pad 7 tablet with LifeShield software that you can use to control everything. Additional sensor pricing is similar to what you'll pay with SimpliSafe. Professional monitoring prices also vary from company to company.

emergency alarm systems

These sensors are similar to the motion detectors that turn on outdoor floodlights. That approach can cut costs, but we don’t recommend it. Motion sensors cause the majority of false alarms. Worse, they detect burglars only after they’ve entered your home. That can create a dangerous situation where you come face to face with a burglar in your hallway. Door and window transmitters are the only way to detect break ins immediately.
