Home Security Sensors: What You Need to Know

Home security systems use a variety of technologies to create a security net around your home. The majority of the components in your security system are sensors designed for a specific purpose. There are many types of sensors that you should combine to make a comprehensive security system. Here is what you need to know about the different types of security sensors. 

Magnetic Sensors

Magnetic sensors are one of the most commonly used types of sensors in home security. It places two magnetic sensors next to each other and activates the alarm when the two magnets move away from each other. These are used for entrance points like doors and windows. These sensors only work in pairs and only work when the two pieces move outside of each other’s magnetic field. 

Motion Sensors

Motion sensors are used to detect motion in an area. There are three types of sensors: passive IR sensors, tomographic motion sensors, and microwave sensors. IR sensors detect infrared light, which is radiated by most living things. Tomographic motion sensors use radio waves to detect motion. 

While you may be able to secure an area with one IR sensor, it takes a tomographic sensor and several radio receives to secure an area. Microwave sensors work the same way that tomographic sensors do, but with electromagnetic radiation. They have a long range and are not hindered by objects in the area. 

Glass Break Detectors

Glass break detectors listen for the specific sound frequencies of breaking glass. These frequencies are far out of human hearing or the ability to reproduce those frequencies by other means. For the best results, they should be placed near the window or door so that they are more likely to hear the glass breaking. 

Beam Sensors

Beam sensors are similar to the laser tripwires that you see in movies. They use an emitter to send a beam of light to a receiver, which you can use to block a doorway or entrance. If the beam is interrupted, it will set off the alarm. 

Beam sensors have the smallest coverage area of the sensor types since it only covers the space between the emitter and the receiver. There are some models that you can use outside, which is a great way to extend your perimeter outside of the home. This way, you don’t have to wait until an intruder tries to get inside to set off the alarm. 

Life Safety Sensors

Life safety sensors cover the widest array of alarms. Fire alarms (smoke detectors) are required in most homes. They can detect changes in the air, such as smoke particles or rapidly rising heat. Flood sensors can detect water building up on the floor. Carbon monoxide sensors can detect rising levels of carbon monoxide, which is odorless and colorless. Adding these sensors to your home is a great idea no matter what security system you use.
