Home Alarm Systems

In order to fully understand how infrared motion detectors work in security systems, users must first understand the function of infrared light. According to the National Aeronautics and Space...

PIR (Passive InfraRed) alarms are used to detect the heat, or heat energy, dissipated by a person moving within the detectors' field of view. The alarms also will detect dogs, cats, raccoons, or...

Someone may have suggested that you secure your home with a motion sensing device. While some may think of this as "movie" technology, people have been using contraptions to detect motion for more...

Most of us have come in contact with motion detectors at some point in our lives. They are everywhere, from the home to the grocery store. If you have visited a friend or family member's house...

Infrared motion sensors are common in many home security systems and other everyday places such as stores. Infrared motion detectors are relatively inexpensive and effective in an enclosed...

Active motion detectors send out signals to detect motion. One of the simplest types of active detectors is a beam motion detector. A beam of infrared light is directed toward a light detector....

Alarms make us feel safer in our homes and add security while we are away. Many alarms are hooked up to a central control box and can only be accessed with a security code.

Laser security systems used to be difficult to install and rarely available to anyone other than the super-rich. Now, there are dozens of different security systems on the market that utilize...

Home security systems keep your home safe by deterring intruders and automatically contacting the local authorities in the event of a breach. Some advanced systems also include carbon monoxide...

Passive infrared sensors work by measuring incoming infrared energy. They do not emit energy themselves, which is why they are called "passive." Infrared energy is released when heat is created....

There are two basic kinds of motion detector sensors. They are categorized based on how they detect motion. The first type is called an active sensor. Active sensors emit energy, usually...

Radar motion detectors emit a constant stream of microwave radiation and bounce that energy off the surroundings. The detector then compares the original signal to the reflected signal and notices...

Photoelectric detectors use an infrared light sensor to detect movement across the beam’s path. Follow these steps to determine where to install a photoelectric detector.

Photoelectric detectors use infrared light to detect an object or person passing through a beam. Follow these steps to use a photoelectric sensor as part of your home security system.
