If you’re looking for suitable devices that will enhance the security of your home, you should definitely consider buying alarm sensors. These useful devices can detect an intruder’s illicit presence at your home and inform the alarm system to switch on the sirens so that you’re instantly aware of the intrusion. As there are several types of sensors available for alarm systems nowadays, it’s important that you have sufficient information about each type before you make your purchase. That way, you’ll be able to select one that is most appropriate for your home.
The first type of alarm sensor available is called a contact sensor. Most robberies involve burglars entering from external doors and thus, it’s essential to protect all doors which lead into your home. Contact sensors use circuit breakers that are magnetic. These can be placed on the door’s edge so that whenever a burglar tries to open the door, the sensor senses the movement and activates the alarm.
Then, you’ll also find window contact sensors. These can be either wired or wireless and are made to sense when your window is closed or opened. Although, they can’t sense breaking glass, they set off the alarm system whenever a burglar breaks the contact among the sensors.
Motion sensors are another type that you can buy. These are very popular and can be classified into two categories: passive infrared sensors (PIRs) and dual-tech motion sensors. The PIRs use infrared radiation or a person’s body heat to detect motion. They come with a set of lenses to detect motion in the sensor’s field of view. Technological advancements have minimized the chances of false alarms. Dual-tech sensors, on the other hand, make use of both microwave and passive infrared technologies. These devices are specifically designed to prevent false alarms, as motion must be detected by both technologies in order it set off the alarm.
Last but not least, there are glass-breakage alarm sensors that are best used with window detectors for detecting high frequencies emitted by a breaking glass. However, these sensors are not triggered when an intruder tries to open a window and hence should be used with window sensors for complete protection.
When looking to buy an alarm system, it makes perfect sense to check with professional home security experts. They are in a better position to assess your specific needs and recommend the option that is best for you.
