High power lights that illuminate all night tend to consume a lot of power which results in large electricity bills. Active infrared motion detector Miami Beach Coral Gables. This is particularly true with outdoor flood lights that are bright and produce a lot of lumens. Also most solar lights aren’t able to work all night if they need to provide continuous illumination. To solve this problem a device called a Motion Detector or Motion detector is used together with a lighting fixture. Active infrared motion detector Miami Beach Coral Gables.

What are Motion detector and Motion detection?

A Motion detector or Motion Detector is a device that is used for detecting a movement in a certain range in front or around the detector. Usually it is used to detect Motion of humans and is used for both safety and security purposes. Active infrared motion detector Miami Beach Coral Gables.

Motion detection is such a process, where a special Detector is used for detecting changes of different objects (mostly humans) in the Detectors detection range that can either be an outdoor or an indoor area. The most basic Motion detectors are able to detect movement of objects in an area from 2 – 5 meters (6.5 to 16 feet) up to 20 meters (70 feet) and more.

There are different types of Motion detectors from infrared, optical to radio wave and others, and each of these types are used for specific occasions. Active infrared motion detector Miami Beach Coral Gables. For example, infrared Detectors monitor changes in infrared wave or heat in the observable area and turns on a light, Alarm or a security camera when changes in the infrared spectrum are detected. Detectors that use radio frequency detection sends out microwave signals to monitor a room and when an object walks in detection area the Detector detects changes in the microwave field and signals the system that there is a moving object in the room. Video cameras can also be used for Motion detection by algorithmically comparing images, when someone walks into the room the picture and pixels changes and the special algorithm can detect these changes.

Where are Motion Detectors used?

Motion Detectors are used together with some kind of other devices, such as security cameras, Alarm or lightings. One of the most common usages of a Motion Detector is together with an Alarm system. Active infrared motion detector Miami Beach Coral Gables. These Alarm systems are installed in both individual properties as well as commercial buildings to detect Motion of unwanted trespassers. When a burglar walks into the detection range of the Detector it automatically starts the Alarm. Motion detectors are also used together with security cameras, when Motion is detected the security camera is turned on to catch the person walking by the observed location.

More advanced Motion Detectors are used in many new technologies, such as gaming consoles, smartphones, robotics and others. Active infrared motion detector Miami Beach Coral Gables.

Besides previously mentioned applications, Motion detectors are often used together with lights and lighting systems both for security and safety purposes. Active infrared motion detector Miami Beach Coral Gables. When a person walks into an area which is monitored by the Motion Detector, the light is automatically turned on at the moment, when a Motion is detected. Motion activated lights are often used together with security cameras and Alarm in security systems. Active infrared motion detector Miami Beach Coral Gables.

The most popular type of Motion lights is Motion activated flood light. These lights are used for both safety and security purposes. Active infrared motion detector Miami Beach Coral Gables. Motion activated outdoor flood lights are used for illuminating an outdoor area at night, starting from front door illumination to large parking lots. From safety aspect, these lights help to illuminate a dark area at night, so that a person can safely walk to the desired place, and at the same time Motion detector helps to save energy by turning the light on only, when someone walks by and turning it off after the person has safely walked to the desired place. At the same time these lights can be used for security purposes to uncover a burglar from the dark and scare him away from your property. Active infrared motion detector Miami Beach Coral Gables.

Occupancy Detectors are used in indoor places to detect if there is a movement in the room and turn the light on or off accordingly. These Detectors help to save both individuals and companies a significant amount of money on electric bills each year. Active infrared motion detector Miami Beach Coral Gables.

Types of Motion detectors

Motion detectors can be categorized into three types – active, passive and combined Detectors. Each of these Detectors responds to different actions and each is used in different situations. Active infrared motion detector Miami Beach Coral Gables.

Active Detectors

Active Detectors use a technique that sends signals or waves across the room or another place, where the Detector is installed and monitors the changes in wave response time. When an object moves in the detection area, micro or other types of transmitted waves collide with the object in the room and responds back to the detector much quicker. The motion detector is able to understand these changes and send an electrical signal to the Alarm system, light or another type of device that is connected to the Motion detector. Active Detectors are used to detect any kind of Motion in detection range, which means that wind moved tree branches could be regarded as movement and detected by the Detector, which then could trigger the outdoor lighting. Active infrared motion detector Miami Beach Coral Gables.Active Detectors that use microwaves for movement detection are mostly used in such applications as automatic doors on shopping malls and similar applications, but can also be found in house Alarm systems and are used for indoor lighting systems. Active infrared motion detector Miami Beach Coral Gables. Active Motion Detectors are not the best solution for outdoor lighting as the movement of random objects such as wind-blown things, smaller animals and even larger insects can be detected by the active Detector and lightning will be triggered.

Passive Detectors

Passive Detectors or PIR Detectors (passive infrared Detector) in opposite to active Detectors does not send out anything, but sits in the corner of a wall or other place and waits for the infrared light to reach the Detector. Active infrared motion detector Miami Beach Coral Gables. Passive Detectors scan the room or area it is installed for infrared heat that is radiated from living beings (actually heat is radiated from any object with a temperature above absolute zero, most from humans). When a human walks into the detection area of a passive Detector, it detects heat emitted from that human and triggers Alarm or turns on the light. Active infrared motion detector Miami Beach Coral Gables. These Detectors would not be effective if they could get activated by a small animal or insect that moves in the detection range, however most passive Detectors can be adjusted to pick up Motion of object with a certain level of emitted heat, for example adjusting the Detector to pick up movement only by humans.

Combined (Hybrid) Detectors

Another Motion Detector type that has become popular recently is combined or dual technology Detectors that have a combination of both active and passive Detectors. It activates light or Alarm only in such occasion, when Motion is detected by both active and passive Detector. Active infrared motion detector Miami Beach Coral Gables.Combined Detectors are useful for Alarm systems to reduce the possibility of false Alarm triggers. Active infrared motion detector Miami Beach Coral Gables. The most popular type of dual technology Detectors combines a PIR and a microwave Detector. However this technology also has its downside. It cannot provide the same level of safety as separate PIR and microwave Detectors, because Alarm is triggered only when Motion is detected by both Detectors. So for example, if a burglar knows how to evade one of the Detectors, his movement is going to be detected just by one Detector, no signal will be sent to the Alarm system and it won’t be turned on.

Active, passive or combined Detectors for outdoor and indoor lighting

When looking at Motion activated flood lights you may have come across the fact that there are very few manufacturers that indicate what type of Motion Detector is used for the light. However, this is because the largest part of lights (especially outdoor lights) has passive infrared Motion Detectors. Active infrared motion detector Miami Beach Coral Gables. And if you think more, it makes a lot of sense that passive Motion Detectors that use heat emitted from a human are a lot better suited for lighting than active Detectors that sends and receives signals and detects changes in wavelengths. Active Motion Detectors can be found in some indoor lights and they are not the best solution for outdoor lighting as the movement of random objects such as wind-blown things, smaller animals and even larger insects can be detected by an active Detector. Active infrared motion detector Miami Beach Coral Gables. The light will get triggered much more times without a purpose, which will result in larger electricity consumption, will degrade light bulbs faster and may disturb you and your neighbors at night.
