Because we can’t keep vigilant watch over our homes at all times, security sensors do it for us, providing 24/7 protection against anything that threatens your most important assets—home and family. There are a variety of home security sensors on the market, but they fall into three main categories:
While each of these types of sensors plays a vital role in securing your home, each fills a specific need that the others do not. In the interest of gleaning the most thorough protection of your home, it makes sense to consider incorporating a combination of the different categories of sensors, which will layer your home’s safeguards and increase your overall security exponentially.
How do Security Sensors Work?
Each type of sensor uses a different technology and within the three categories, there are varying degrees of options as well. Essentially, here is how each breaks down:
- Door and window sensors use a sensor installed on the door or window, and a magnet attached to the door or window frame. The armed sensor triggers the alarm when the door or window is opened, disturbing a simple circuit connected by a magnetic current.
- Glass break sensors rely on both acoustic (sound) detection and shock (vibration) detection. When shattered glass is detected, the alarm sounds.
- Motion sensor alarms use one or more types of detectors such as infrared, which detects heat from a person’s body, to detect motion. Motion sensors may be used indoors and outdoors to monitor “zones” and then sound an alarm when motion is detected in these protected areas.
Who are Security Sensors for?
Security sensors are known as the first line of defense when it comes to securing your home against intrusion. Yet, having only one type of security sensor may not provide optimal security. A home security system has to be prepared for any break-in scenario since an intruder’s actions and point of attempted entry are unpredictable. Consider installing one or more security sensors if you are a homeowner who:
- Wants to know if someone is approaching your home or otherwise on your property
- Wants the ability to arm all accessible points of entry—windows and doors—the number one way intruders break into residential properties
- Has several accessible glass points of entry in the home
- Wants to be alerted to any movement in entries, hallways or other, often remote areas of the home
- Is away from home all day or who travels often
- Owns a vacation home or cabin and wants it secured
- Wants to monitor the security status of the home and family members in the home or others—gardener, housekeeper, babysitter—who are coming and going
How to Choose a Security Sensor for Your Home
Beyond the peace of mind home security sensors provide as part of a home security system, they are practical, versatile, and ideal for homeowners who want to build their home security system little by little. Once immediate needs are determined, it may make sense for some homeowners to secure direct access doors and windows first, while another may prefer the protection of and exterior motion sensor. Either way is the right way if it’s satisfying an immediate home protection need. And there’s always the option to add more security sensors as home and family needs change.
