What is IR beam detector?

Infrared beam sensors detect the motion of objects both in light and dark with equal reliability. The infrared sensors do not need any contact with the object to be detected.

How does an alarm beam work?

The transmitter sends an undetectable and continuous pulse of infrared light to the receiver. If an intruder or object, for example, a person, dog or falling branch, breaks the invisible beam, an alarm signal will be triggered.

How does an infrared alarm work?

Active infrared sensors work with radar technology and they both emit and receive infrared radiation. This radiation hits the objects nearby and bounces back to the receiver of the device. Through this technology, the sensor can not only detect movement in an environment but also how far the object is from the device.

What are infrared beams used for?

IR beam detectors are commonly used to detect entry through a perimeter and may be used to surround a property or asset. These are typically high-value assets, including high-end homes, industrial sites, and corporate headquarters.

How do you install a beam detector?

The beam detector can be mounted with the transmitter/receiver on one wall and the reflector on the opposite wall, or both suspended from the ceiling, or any wall/ceiling combination. In the case of the ceiling mount, the distance from the end walls should not exceed one-quarter of the selected spacing (7.5 ft.

What are the dangers of infrared waves?

Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.

Where do you put a beam detector?

Are beams good security?

“Free-standing beams are not as effective for several reasons. They are susceptible to lightening damage, they are easily triggered by pets and plant movements, and criminals can easily bypass and damage them. The whole objective of perimeter security is to stop criminals from reaching the house.

Where can you use a beam detector?

Beam type smoke detectors are mostly used in places with high ceilings like basketball courts, warehouses, movie theatres etc. Detection with optical smoke detector can be slow in these places. Because smoke has to reach the detector mounted to the ceiling.

How do you test a beam detector?

Lay the “Alarm” test filter section over the receiver lens. The alarm should sound within 15 seconds. If the detector does not alarm, check and correct the wiring, then test the unit again. If the alarm does not go off after the second test, return the beam detector for repair.

What causes motion sensor false alarms?

False Alarm Causes Direct sunlight hitting the sensor can trigger a false alarm. Heating vents located in the room. If they are located within the sensor’s field of vision, they may cause false alarms. Pets that are able to get too close to the sensor.

Where are infrared sensors used?

Application of Infrared Sensors Infrared sensors from InfraTec are used in gas warning devices, gas analysers, medical gas measurement technology, flame detectors and in contactless precision temperature measurement. These devices use the intensity measurement of infrared radiation in defined spectral ranges.

Do IR sensors work in the dark?

Since infrared energy is present and can be detected regardless of the amount of light in the environment, a PIR motion sensor will work just fine in the dark.
