High power lights that illuminate all night tend to consume a lot of power which results in large electricity bills. Sensors that detect movement 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 Security Sensors or Security detector is used together with a lighting fixture. Sensors that detect movement Miami Beach Coral Gables.

Picking a motion sensor can be tricky. There are dozens of different makes and models on the market, and they come in all shapes and sizes. Sensors that detect movement Miami Beach Coral Gables. If you’re using an outdoor sensor, you want something that will be able to hold up to all kinds of weather, whereas if you’re using a sensor inside, you may want something discreet that won’t clash with your decoration. Motion sensors also have different detection area sizes and different alert types. Sensors that detect movement Miami Beach Coral Gables.

What is Security detector and Security detection?

A Security detector or Security Sensors 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 Security of humans and is used for both safety and security purposes. Sensors that detect movement Miami Beach Coral Gables.

Security detection is such a process, where a special Sensors is used for detecting changes of different objects (mostly humans) in the Sensors detection range that can either be an outdoor or an indoor area. The most basic Security 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 Security detectors from infrared, optical to radio wave and others, and each of these types are used for specific occasions. Sensors that detect movement Miami Beach Coral Gables. For example, infrared Sensors monitor changes in infrared wave or heat in the observable area and turns on a light,  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 Sensors detects changes in microwave field and signals the system that there is a moving object in the room. Video cameras can also be used for Security detection by algorithmically comparing images, when someone walks into the room the picture and pixels changes and special algorithm can detect these changes.

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

More advanced Security Sensors are used in many new technologies, such as gaming consoles, smartphones, robotics and others. Sensors that detect movement Miami Beach Coral Gables.

Besides previously mentioned applications, Security detectors are often used together with lights and lighting systems both for security and safety purposes. Sensors that detect movement Miami Beach Coral Gables. When a person walks by an area which is monitored by the Security Sensors, the light is automatically turned on at the moment, when a Security is detected. Security activated lights are often used together with security cameras and s in security systems. Sensors that detect movement Miami Beach Coral Gables.

The most popular type of Security lights is Security activated flood light. These lights are used for both safety and security purposes. Sensors that detect movement Miami Beach Coral Gables. Security 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 desired place, and at the same time Security 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 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. Sensors that detect movement Miami Beach Coral Gables.

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

Types of Security detectors

Security detectors can be categorized in three types – active, passive and combined Sensors. Each of these Sensors respond to different actions and each are used in different situations. Sensors that detect movement Miami Beach Coral Gables.

Active Sensors

Active Sensors use technique that sends signals or waves across the room or other place, where the Sensors 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. Security detector is able to understand these changes and send an electrical signal to the  system, light or other type of device that is connected to the Security detector. Active Sensors are used to detect any kind of Security in detection range, which means that wind moved tree branches could be regarded as movement and detected by the Sensors, which then could trigger the outdoor lighting. Sensors that detect movement Miami Beach Coral Gables.Active Sensors 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  systems and are used for indoor lighting systems. Sensors that detect movement Miami Beach Coral Gables. Active Security Sensors are not the best solution for outdoor lighting as movement of random objects such as wind-blown things, smaller animals and even larger insects can be detected by the active Sensors and lightning will be triggered. Sensors that detect movement Miami Beach Coral Gables.

Passive Sensors

Passive Sensors or PIR Sensors (passive infrared Sensors) in opposite to active Sensors 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 Sensors. Sensors that detect movement Miami Beach Coral Gables. Passive Sensors 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 temperature above absolute zero, most from humans). When a human walks into the detection area of a passive Sensors, it detects heat emitted from that human and triggers  or turns on the light. Sensors that detect movement Miami Beach Coral Gables. These Sensors would not be effective if they could get activated by a small animal or insect that moves in the detection range, however most passive Sensors can be adjusted to pick up Security of object with certain level of emitted heat, for example adjusting the Sensors to pick up movement only by humans. Sensors that detect movement Miami Beach Coral Gables.

Combined (Hybrid) Sensors

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

Active, passive or combined Sensors for outdoor and indoor lighting

When looking at Security activated flood lights you may have come across a fact that there are very few manufacturers that indicate what type of Security Sensors is used for the light. However, this is because the largest part of lights (especially outdoor lights) has passive infrared Security Sensors. Sensors that detect movement Miami Beach Coral Gables. And if you think more, it makes a lot of sense that passive Security Sensors that use heat emitted from a human are a lot better suited for lighting than active Sensors that sends and receives signals and detects changes in wave lengths. Active Security Sensors can be found in some indoor lights and they are not the best solution for outdoor lighting as movement of random objects such as wind-blown things, smaller animals and even larger insects can be detected by an active Sensors. Sensors that detect movement 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.

If you see that Security activated light is commercialized as „PIR Sensors light” or „Light with a PIR Security Sensors” you can be sure that this type of light uses a passive Security Sensors. Sensors that detect movement Miami Beach Coral Gables.

What a PIR detector is?

A PIR is a passive infrared Security Sensors. It detects infrared energy, which is in a form of a temperature that is radiated from body of humans, animals and other objects. A PIR Sensors can detect Security in certain distance and angle, so PIR Sensors have different working areas. Sensors that detect movement Miami Beach Coral Gables.

PIR Sensors are simple electronic devices and their only job is to detect changes of infrared radiation in form of a heat from detection area. Infrared light moves electrons in the Sensors, which are captured and amplified in an electrical signal. This signal then is used to alert the  system or trigger a Security light to start illuminating. PIR Sensors structure is pretty simple and consumes little energy and most basic Sensors cost just few bucks, so they are widely used in security systems for homes and businesses as well as indoor and outdoor lights and lighting systems, and also are used in robotics and other industries. Sensors that detect movement Miami Beach Coral Gables.

A PIR Security detector

PIR Sensors can have different adjustable settings. For example, some Security detectors can be set to respond to energy in varying temperatures. For example a PIR Sensors can be set to respond only to 10-12 μm (micrometer or micron) radiation, which is the average from a human body. Sensors that detect movement Miami Beach Coral Gables.This way the Sensors will not detect Security of smaller animals like dogs and cats. Some Sensors are so sensitive that they can pick up a heat emitted from birds and larger bugs and the light is turned on after Security detection.

In what application PIR detectors are used?

Sensors that detect movement Miami Beach Coral Gables

PIR Sensors same as active Sensors are mostly used in security  systems to detect thieves and trespassers. Sensors that detect movement Miami Beach Coral Gables. There are even some special pet immune Security Sensors that are used in indoor  systems and can be set to ignore animals at specific weight. PIR Sensors are often used together with active microwave Sensors in security systems, to prevent false s triggered by one or other Sensors. Sensors that detect movement Miami Beach Coral Gables.

Besides  systems, PIR Sensors are often used in Security activated lights. This includes both indoor and outdoor lights. Sensors that detect movement Miami Beach Coral Gables. PIR detectors are very popular combination with outdoor flood lights, as they tend to consume lot of energy because of their brightness, and a Security Sensors helps to save energy and money by turning the light on only when a Security is detected in front of the light. PIR Sensors are also used in solar lighting. Solar lights work on batteries that get charged in day by sunlight and power the light at night. Based on the size of the battery lights can provide continuous illumination from couple of minutes to few hours and larger lights can even work for all night. To prolong the illumination period solar lights are often equipped with a Security Sensors. With help of a Security Sensors lights that have batteries with capacity of less than an hour or even less than a half an hour can provide illumination for all night if used in an area, where the light needs to be turned on just few times at night, for example, when used as a front door light. Sensors that detect movement Miami Beach Coral Gables.

From what parts PIR Sensors consists?

The basis of all PIR Sensors is practically the same, only few parts such as lenses are different, which is why there are PIR Sensors with wider and shorter detection ranges as well as different sensitivity settings. Sensors that detect movement Miami Beach Coral Gables.

The PIR Security detector consists of such parts:

PIR Sensors – The PIR Sensors is the part which is responsible for measuring the infrared light emitted from an object in its detection area. Sensors that detect movement Miami Beach Coral Gables.The Sensors is protected from outer factors such as humidity by a metal casing. On top of the casing there is a small surface with infrared-transmitting material under which is the infrared Sensors. Sensors that detect movement Miami Beach Coral Gables. The Sensors (usually there are two Sensors) generates electricity from the infrared radiation or heat.

Lens – The lens is what can be seen from the outside of the detector. Lens is much wider than the Sensors and its job is to bend light and focus it on the infrared Sensors. Lens is made from a plastic which allows light with certain wavelengths to reach the Sensors under the plastic cover. Sensors that detect movement Miami Beach Coral Gables. The large lens is made from multiple smaller Fresnel lenses, which can capture more light on a smaller lens surface than regular lenses. Lens also protects the Sensors from outer objects like dust getting to the Sensors. To sum up, lens of the Security detector is responsible for couple of tasks:

Focus the light on the infrared Sensors, so it can cover much larger area;

Filter the light to capture the right wavelengths, for example to detect movement only by humans and not by smaller animals;

Protect the Sensors from outer impacts and objects.

Electric circuit – This consists of some resistors, capacitors, chips and adjusters. There can be couple of adjusters inside a Security detector light:

Sensitivity adjuster – regulates a detection range of the Sensors;

Timer to set the time of how long the light needs to illuminate after Security has been detected by the Sensors;

Timer to set the time of how long the light needs to be turned off after no further movement is detected. Sensors that detect movement Miami Beach Coral Gables.

How PIR detects Security?

Infrared wavelength is longer than a wavelength of a visible light, so infrared light cannot be seen by humans, but it can be captured by Security detectors. Sensors that detect movement Miami Beach Coral Gables.Not all materials that can transmit visible light like glass of windows are able to transmit infrared light. However materials such as silicon or different types of plastic are good for transmitting infrared waves and can also be used to filter the correct wavelengths of the infrared light.

A PIR Sensors detects changes in amount of infrared radiation in its detection area. Infrared radiation basically is heat coming from objects such as humans and the amount of infrared radiation mostly depends on the temperature of the object. Sensors that detect movement Miami Beach Coral Gables.

PIR Security Sensors operation

For example, when a human walks into the Sensors detection range, the temperature in that range changes from a temperature of room objects (if used indoors), which is lower, to a temperature of a human body, which is higher and when a human walks out of the detection range the temperature changes back to the temperature of room objects. Sensors that detect movement Miami Beach Coral Gables. A PIR Sensors detects these changes in temperature and transfers them into electrical signals which are passed to the  system that gets activated or turn on a light that starts to illuminate.

Advantages of Security sensing lights over regular lights

Security Sensors are common options for flood lights and solar lights. Sensors that detect movement Miami Beach Coral Gables.  They offer numerous advantages for both high powered outdoor flood lights as well as solar lights, starting from energy savings to improving the lifetime of certain parts of lighting fixtures when compared to regular lights. Here are few advantages of Security activated lights over regular lights. Sensors that detect movement Miami Beach Coral Gables.

Lower energy consumption and lower electricity costs

If you have ever owned a regular flood light, you must know how much energy such a light can consume when illuminating nonstop for all night. Sensors that detect movement Miami Beach Coral Gables. The interesting part is that in most applications we actually don’t need the light to provide continuous illumination all night long, but we need the light to be turned on in a certain situation, mostly when someone is in the area, which light should provide illumination. In these situations Security activated Sensors are very useful. Security Sensors will trigger the light only when someone is moving in its detection range and will turn the light off afterwards, this may be one or multiple times at night based on the area the Security light is installed. Obviously a light that illuminates for 8 full hours will consume a lot more electricity than the same light that will get triggered just few times at night and will illuminate for couple of hours or even less. Lower energy consumption results in lower electricity bills and based on the power and brightness of the fixture as well as the intensity of usage the savings on electricity may be colossal. And because most Security Sensors cost just few bucks and Security activated lights cost practically the same as regular lights, solar Security light will pay itself off in the first days to month of usage. Sensors that detect movement Miami Beach Coral Gables.

Solar lights

Other types of lights that benefit hugely from Security Sensors are solar lights. You will see much more Security activated solar lights than ones without a Security Sensors, and there is a good reason for that. Sensors that detect movement Miami Beach Coral Gables. Solar lights have built in batteries with varying capacities, solar lights with larger lead acid or lithium-ion batteries can provide continuous full night illumination, while medium and smaller light that have lower capacity Ni-MH or Ni-Cd batteries likely won’t be able to provide energy for longer than an hour or two. This is why most solar lights, especially solar flood lights, are equipped with Security Sensors. Sensors that detect movement Miami Beach Coral Gables. Solar lights are mostly used in such areas that do not require a nonstop illumination, but needs to be illuminated few times at night, such as front door lights that need to provide illumination for few minutes so you can safely walk to the house at night. Sensors that detect movement Miami Beach Coral Gables. Also, when used for security purposes to scare unwanted trespassers off your property, whether it is a bugler or some kind of animal in your backyard. It would not make sense to use a regular flood light that would illuminate nonstop all night in these situations. These are just some basic example how solar lights benefit from a Security Sensors. Same as with regular Security activated lights, the largest benefits from Security Sensors for solar lights is energy conservation and ability to provide longer illumination times, while running on batteries. Sensors that detect movement Miami Beach Coral Gables.

Longer lifetime for parts and bulbs

Because Security activated lights do not require to illuminate for such long periods of time as regular lights, they not only save more energy but also help to extend life span of bulbs used in the lighting fixture. Sensors that detect movement Miami Beach Coral Gables. This can be attributed to practically any light bulb (except CFL as continuous turning on and off will decrease the lifespan of the bulb), even LED diodes that have much higher life span of 25000-50000 hours and more will benefit in long run.

More practical to use in certain applications

Security activated lights are simply more practical to use in some applications than regular lights, and opposite around. Security lights will benefit in such applications that require illumination only when a person walks by a certain area or stays in that area for fixed amount of time. Security lights will also benefit areas, where it is inconvenient or impossible to install a light switch. Sensors that detect movement Miami Beach Coral Gables. Areas where Security lights proves to be useful are front door lights, staircase lights, garden and backyard lights, lights that provide illumination on sidewalks when walking by a personal house or a commercial property, lights on basements or other places with insufficient light in a house and other similar cases.
