Door Security

Garage Doors & the Garage always has one door, and modern garages also have one inside door which leads to the house. This is a common security problem in many homes that have attached garages. If you're protecting your home, your single security sensor should be inside the house, covering the doorway that leads from the garage. If you want to prevent car or other property in your garage from being stolen, you'll either need magnetic switch sensors on the outside door, or a motion sensor inside the garage. Place it at a height where the car itself won't block the sensors operating area. If the garage only has a single window, you may only need a glassbreak sensor to prevent entry.

Garage door openers can also be a security risk if they are left on the manufacturer's original settings. Make sure to program your own settings. The locks on automatic door openers are pretty solid and difficult to break through.

Front Entry Door & Front entry doors should have a deadbolt lock in addition to the regular door lock. A magnetic door contact sensor is sufficient for many front doors since the major problem for intruders is getting through the door. Without that, they aren't getting in.

Back Entry Door & Back entry doorways are the second favorite point of break-in for burglars, so this door shouldn't be neglected. It should also have a deadbolt lock in addition to a regular door lock. If there is a hallway or doorway near the back door, a motion sensor could be placed there to ensure that the traffic area is well covered. If nothing but a room exists, you could place a motion sensor on the wall facing the door.
