Motion Detectors

Motions detectors play a huge role in ensuring security and energy efficiency at your home and business. Ranging from burglar alarms to security cameras, you can find them in a wide range of options. Since there are many other options to choose from, here is the guide that will help you pick the best.

A motion detector or sensor is an electronic device or set of devices that detect movement. They are an integral part of the home and business security. It comprises three main components: a sensor unit, hardware, and an embedded computer. Motion sensors are highly in use for various purposes such as active floodlights, activate switches, triggering an audible alarm, and more. You can find both active and passive motion sensors in a wide variety of options. Active sensors comprise both transmitter and a receiver. On the other hand, the passive one does not contain a transmitter. It is often a part of a home security system. You can find motion detectors at different prices offered by different brands and sellers. On this page, we are going to explore some useful information about outdoor motion sensor alarms for sale online in the UAE.

Types of motion detectors to choose from

You can find motion detectors in many varieties like PIR, infrared, ring motion sensor, outdoor motion sensor, and more. Although, all of them function differently. Motion sensors, depending on their type, react to different situations such as movement in your room, doors, and windows. They can also activate a doorbell when someone is close to the door. It is especially helpful when you have kids. These sensors may also give you an alert whenever your kids enter areas that are restricted, like the medicine cabinet, workout room, the basement etc. Energy conservation is another feature you can avail of. Although while you buy a motion sensor alarm in the UAE, you need to keep some considerations in your mind. Towards the end, you can find some tips too that will assist you in picking the best.

PIR motion sensor

PIR motion sensor stands for passive infrared motion sensors. You must have spotted this one while you were entering a restroom or office. It usually has a white cover. They are low power, very easy to use, small and not very costly. Different motion sensors detect motion differently, and this one does it by detecting the change in temperature between the warm body and the background. Everything emits some amount of radiation, but the human body does a good amount. PIRs usually come with a pyroelectric sensor. It is good at detecting different levels of infrared radiation. About its construction, the PIR has two slots of a material that is sensitive to infrared. When it senses differential change between the two slots, it will result in a pulse. This is how it detects movement.

Ultrasonic sensors

Ultrasonic sensors may come in active and passive variants. Active ones produce ultrasonic waves. Then, they determine the waves reflecting off a moving object. Passive ones, on the other hand, are useful for particular sounds like glass breaking, metal on metal and more. You will find them very sensitive. However, they are expensive and also prone to fake motion detector alarms. Ultrasonic sensors are common as proximity sensors. You can find them in automobile self-parking technology and many other anti-collision safety systems. You can also find them manufacturing technology. They are not even influenced by an environment of gas, smoke, or other airborne particles. You can find such sensors in a wide range of options. They may vary in their features, capabilities, sizes, brands, and more factors.

Hybrid sensors

As the name suggests, a hybrid technology motion sensor works as a combination of both active and passive sensors. It means that it will activate a light or motion sensor alarm only when motion is detected by active and passive sensors both. Therefore, there will be lesser chances of false alarm triggers. However, it can be disadvantageous sometimes because the level of safety is compromised here. For example, if the intruder knows how to escape one of the sensors, he or she is all free. But if you are fed up with false alarm triggers, then this may be useful for you. You can find them in different varieties depending on your preferences and the level of security you need.
