A motion detector is an integral part of your security system, as the main device that is able to detect when someone is inside your home when they shouldn’t be. There is a variety of technologies used in detecting movement in an area. When the motion sensor is tripped, a signal is sent directly to your security system’s control panel and out to our monitoring center, alerting you and central station to a potential threat in your home.
There is a time and place for all different types of motion detectors, but the most common motion sensing feature used for security systems is a passive system that detects infrared energy. This type of technology is best for detecting a human body due to its temperature sensitivity. Humans, having a skin temperature of about 93 degrees F, radiate infrared energy with a wavelength between 9 and 10 micrometers. This radiation or energy is invisible to the human eye but is typically programmed to be sensitive to the sensors in the range of 8 to 12 micrometers.
An intruder entering the armed area is detected when the infrared energy emitted from the intruder’s body is focused by a Fresnel lens or a mirror segment and overlaps a section on the chip which had previously been looking at some much cooler part of the protected area. That portion of the chip is now much warmer than when the intruder was not present. At Doyle Security, we provide technology that not only can precisely sense this type of energy, but will also activate your security cameras to begin capturing footage so you can know exactly what is going on in your home. Utilizing the right combination of motion detectors and security features gives your home the full security coverage it needs.
