What are the types of motion proximity sensors?

Passive Infrared (PIR)

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensor's range. They are small, inexpensive, low-power, easy to use and don't wear out. 

Microwave

A microwave motion sensor uses electro-magnetic radiation. It emits waves which are then reflected back to the receiver. 

Dual technology motion sensors

Dual Technology sensors are smart solutions that can help reduce energy waste and provide an additional level of convenience for occupants. They work using a combination of PIR and Ultrasonic technology. 

Where can these proximity motion sensors be used?

Motion sensors are very useful and highly recommended when it comes to security and energy efficiency. They can be used for anti-theft alarms and security cameras, activating these devices when it senses motion in the vicinity. It can be an energy saver by shutting off lights in a building when it senses no motion anymore, which is used regularly in office buildings or restrooms. 

How is motion detected using PIR sensors?

A PIR sensor detects the infrared light radiated by a warm object. It consists of pyro electric sensors which introduce changes in their temperature (due to incident infrared radiation) into electric signals. When infrared light strikes a crystal, it generates an electrical charge.

Do motion sensors have cameras?

Video motion sensors combine video cameras with advanced signal processing. Some recordable motion sensors start recording when they sense motion. Cameras controlled by motion sensors can save you memory storage.

What is the ideal placement for motion sensors?

Placing the motion sensors in the correct position and location is an important aspect. They work best when placed high up to cover a large amount of area. They also function by detecting a fluctuation in heat and therefore it is not ideal to place it near a heating station or windows on a sunny day.  It is not ideal to place it near a door or window, since it can create false alarms if there are slight alterations in infrared energy over time.
