How to Install a Motion Detector Home Alarm System

Choose the features you want for your alarm system, and purchase the one that best matches your needs. Features such as remote calling, monitoring, extra detectors, indoor/outdoor use and wider coverage areas are all available. A remote key fob allows you to control the unit from inside the bedroom, so if you want to wander downstairs at night for a drink of milk you won't trigger it yourself.

Walk around the home and see where a motion detector makes sense. A small home may only choose one that covers a central area where anyone would have to pass through when entering the home. A two-story home with multiple entrances may install an extra one on a corridor leading to the bedrooms, or for the stairs leading to the upper level.

Attach the motion detecting unit to the wall at the height recommended by the manufacturer. The detectors almost always either have a small screw or attach with a latch and hoop tape. If you have a pet and the unit comes with a pet shield, this will cut down on false alarms. Pet shields do not work as well with cats that climb within the coverage area.

Set the alarm trigger for enough time to allow you to open the door and turn off the alarm before the alarm goes off. Program the unit with any numbers to call if that option is available. Pick a password that is easily remembered but unlikely to be guessed by anyone else. Avoid common ones such as pet's or children's names.

Test the unit after it is installed. Walk along the path and check how soon it picks up your presence. If you want to change it to a slightly different pick-up location, now is the time to do so.
