Security is among the paramount needs of any residential and commercial property. Burglars are now using various technological methods to gain access to properties. The conventional security measures efficient in the past are generally useless nowadays in keeping your property safe.
Alarm monitoring systems from Certified Fire Protection can keep intruders off your Utah property. These monitoring systems use sensors to detect intrusion, which in turn sets off the alarm. Several types of sensors are available in the market. Here are three of them:
Passive Infrared (PIR) Motion Detectors
These are the most frequently used sensors since they are affordable and practical. PIR sensors produce their energy and do not need to radiate. They detect any change in ambient temperature or body heat and set off an alarm. The infrared energy from PIR detectors does not pass through glass, so you should not worry that the alarm will be triggered because of outside changes.
These sensors use frequencies ranging from 25 kHz to 75 kHz to detect movements in a limited area. The frequencies are indistinct to human ears and are bounced off ceilings, walls, and furniture in protected rooms. Any movement in the protected area changes the sound wave frequency and triggers the alarm.
These work like ultrasonic detectors but have high-frequency radio waves rather than sound waves. The primary advantage of a microwave detector, unlike other sensors, is the ability of its radio waves to pass through walls. However, like ultrasonic detectors, they do not discriminate passersby and intruders and can be set off unnecessarily.
The technical specifications of the given sensors might slightly differ among different security service providers. In most cases, the alarm set off by these detectors is quickly relayed to your security service provider. The provider will then send the appropriate authorities to your property.
