Garage Door Sensor – Purpose and Types

garage-door-sensorEven though you might want to be everywhere at once, the laws of physics have limited you, so rather than spending every minute sitting in your garage to detect possible intruders, you should have a garage door sensor installed. It’s important to protect the perimeter of your home, and many people actually forget that the garage is part of that. Most homes have access directly into the home from the garage via a door. While these doors usually are able to be locked with the same keys that lock the front and back doors of the home, most people will leave them unlocked due to the hassle of going in and out through the garage every morning and evening and possibly multiple times through the day. Therefore, if someone can get into the garage, they have free and easy access to the house! For this reason, installing a garage door sensor will alert you whenever the garage is opened so that you can apprehend the intruder – or simply go and close it if you forgot to after you brought in the groceries.

The Purpose of a Garage Door Sensor

A garage door sensor’s purpose is to “sense” when something has happened in the garage – most specifically, when the door has been opened. Many sensors will react to motion, but garage door sensors primarily react to the door being opened because that is the main concern for garage entry. Once it has detected movement from the door, the sensor will transmit an alert to the homeowner so that knowledge of the movement is passed on to the person who most needs to know. The alert will be sent to your phone or your garage door monitor in whichever room you’ve placed it. This alert is just like an alarm system, which makes sense because a garage door sensor is, in essence, a garage door alarm. This system may be hooked up through the main home security system so that you can keep all notifications and alerts together.

Home Icon Set 187038405As with all home automation products, there are many types of garage door sensors. Most will feature some sort of monitor or indicator light so that you can see the status of the garage door. Some sensors can be set to recognize how long the garage door has been open, and when programmed for a certain amount of time (say, 20 minutes), they will automatically close after that point. This is ideal for those times when you forget to close the door because you were running late to work or you had to hurry in to help your toddler go to the bathroom. As far as the “alarm” part is concerned, you can set them to either send you an alert or turn on an actual alarm siren to startle intruders away. Some provide visual and audio sensing while others detect only the movement. And most garage door alarms are actually pretty affordable and run in a variety of shapes, styles, and colors.

If you’ve put together a home security system and your garage isn’t yet protected, then your security system is incomplete. Protecting the garage is a key component of home security, and having a garage door sensor will help you to accomplish that.
