How Infrared Detector Work in Security Systems?
- Infrared Detectors Use Infrared Light
- 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 Administration (NASA), infrared light exists in the electromagnetic light spectrum, and operates in a range of frequencies not visible to the human eye. The blanket term "infrared light" encompasses two frequency ranges, "near infrared," which operates at a frequency closer to that of visible light, and "far infrared," a range of frequencies closer to microwaves than to the visible spectrum
- Because of the higher frequency range of far infrared, the infrared light possesses thermal properties that allow it to sense and detect very subtle temperature changes, and this temperature sensory ability is what helps detect movement in a home security system.
- Infrared Detectors Monitor a Room
- In a typical home or office security environment, infrared motion detectors mount on a wall or the ceiling
- Once in place, the motion detectors use far infrared light beams to create a thermal image of the monitored area
- Because every component in a home or office---including furniture, floors, walls and fabric---has a certain heat signature, the infrared motion detector quickly develops a "normal" image of the room and its fixtures
- If this image changes, as it does when a person, animal or object enters the area under infrared monitoring, the detector's built-in circuitry identifies the image change and sends a signal to the security system's control panel.
- Heat Can Affect Infrared Detectors
- Due to the low cost and reliability of infrared detectors, according to Alarm System Reviews, the devices account for the majority of motion detectors in home security applications
- Despite the reliability of the devices, though, they are far from infallible
- Manufacturers of infrared detectors ship the devices with explicit mounting instructions that include strong warnings against placing the detectors near a heat source
- Because the devices rely on thermal imaging, a heat source like a radiator or heat pump vent can quickly change the thermal appearance of a monitored area and trigger a false alarm
- Likewise, an infrared detector mounted to face a window may sound an alarm when the sun sets or rises, or when other environmental factors cause a sudden change in ambient temperature.
- Some Detectors Use Dual Technology
- Although infrared detectors are fairly reliable and relatively inexpensive, Alarm System Reviews reports that an increasing number of infrared detectors also employ microwave technology as a secondary security measure
- In addition to the thermal properties of infrared light, these sensors employ microwaves to quickly and accurately detect movement in a room
- Every few seconds, the detector sends a burst of microwaves out across the monitored room and measures the amount of time the waves take to reflect back to the detector; if the amount of time changes between one burst and the next, the detector registers a change in the room and triggers an alarm
- By combining the far reach of microwaves with the relative reliability of infrared, these "Dual Technology" detectors offer greater reliability than their single-technology cousins
How to Choose a Home Alarm System:
Conducting Preliminary Research
- Survey your home and determine how many windows and doors you want to be 'switched,' or integrated into the home security system
- Determine possible locations for the control panel and keypads. You might find it convenient to place a keypad close to the front door. You might also want a keypad close to the bedrooms. The control panel commands the system, and the keypads allow you to program the system and turn it, or its components, on and off
- Determine how far away windows and doors are from the control panel so that you know how far wires will be routed if you choose a wired alarm system or how far a wireless system needs to communicate with sensors. Keep in mind that it is difficult to install a hard-wired security system unless your house is still under construction
- Decide whether you want a monitored security system that will be monitored 24 hours a day. The central monitoring station 'watches' your home for a monthly fee. A less expensive alternative is a basic sensor system with a dialer accessory that connects the system to your phone lines and dials preselected numbers if the house's security is breached
- Consider your lifestyle. Does anyone in the family often get up in the middle of the night for a snack? Do you have a large pet that roams the house at night? Such circumstances will influence the type of motion sensor you select and how it is installed. It may also call for you or members of your family to take trips to the keypad to prevent false alarms
Choosing the System
- Consult with a reputable home security system adviser
- Choose a system with a control panel that can monitor all the zones you have in your home. Each window or door integrated into the system is considered a zone. A basic system is capable of controlling eight zones. However, many panels permit the addition of expansion modules that allow the system to watch up to 32 zones
- Determine if the routing of the wires for a hard-wired security system might be too long. With a wired system, you will have to drill holes in walls where wires will have to be routed. If the wire run appears too long to you, choose a wireless system
- Make certain that a wireless system can perform up to the distance of the farthest zone
- Be certain that the system you choose can accept fire-protection sensors, carbon monoxide sensors and combustible-gas detectors, anti-freeze-up low-temperature switches (especially in cold climates) and water detectors. Make sure that panic buttons are or can be included
- Choose a system that is user-friendly. Make certain that inputting codes into the keypad is not a complicated process and is one that everyone in the family can learn quickly. You don't want to have to refer to the owner's manual as you input or try to interpret codes
- Work the keypad of the system you select to assure yourself that it is easy to use. Encourage all family members to work the keypad so that you will select one that everyone can use comfortably
