All security alarm systems that are installed at enterprises, as well as in private houses, apartments, consist of several elements. The simplest system consists of a control unit, special sensors, and an alarm unit. The latter can be both sound and light.
Sensors are the main component of any alarm system. They are able to record the movements of various objects that have fallen into the zone, which is controlled by the alarm. After they are triggered, the system begins to react and turn on a light or sound signal. What detectors are there, where can you buy them, what to look for when choosing? The editors of the site "bestx.htgetrid.com/en/" have prepared for your attention, based on the feedback and advice of many buyers, a rating of high-quality motion sensors that are used in burglar alarms in 2020.
Content
Description, device overview
Motion detectors are electronic devices that can detect a variety of movements of objects in certain viewing areas. Simply put, such devices are sensors that are able to record the movement of objects in the space visible to them, inside or outside the room.
Depending on the type of security system used, they can monitor the environment, notifying about the presence of various movements in the monitored area, or automatically initiate the start of various electrical appliances.
Where are used
Due to their functionality, such detectors have a wide range of applications. As a rule, they are most often used in a variety of security systems:
- When creating an alarm system in offices, enterprises, private houses or apartments;
- In video recording systems;
- During the creation of special systems for recognizing unauthorized entry into premises.
Sensors are often used for domestic purposes. For example, such devices are equipped with special outdoor and indoor lighting systems inside or outside the room, which react to human movement. They can also be equipped with doors designed to automatically pass (open or close) people. It should be noted that the use of sensors ensures the safety of people in cars (they are equipped with airbags).
The principle of operation and types of detectors
Ceiling or wall sensors with which the alarm is equipped, as well as various automatic systems (climate control, light on / off) operate due to the principle of recognizing various types of emitted waves. These waves are captured by the sensor and processed. Therefore, such devices are qualified depending on what types of waves they are capable of operating (catching). There are these types of detectors:
- Infrared;
- Ultrasonic;
- Photovoltaic;
- Microwave;
- Tomographic.
Modern security systems are equipped with devices that combine the combined use of a variety of technologies for recognizing moving objects. This allows the number of false alarms to be minimized.
Reference! Modern detectors are equipped with a special feature called the “animal corridor”. Thanks to this function, the sensors ignore the movement of objects, the size of which is below certain, set parameters. Thanks to the presence of this function, the number of false alarms in rooms and apartments where there are pets is significantly reduced.
Criterias of choice
Motion detectors, which are equipped with alarm systems, are able to independently emit waves, and then analyze them, capturing them after reflection. Some models work only thanks to the signals that come to them directly from the environment. Detectors, depending on their ability to initiate incoming waves, are:
- Active;
- Passive;
- Combined.
Motion detectors for signaling, by the type of their connection, are wired and wireless. When purchasing a sensor for an alarm, it is recommended to pay attention to the following technical parameters of such a device:
- Viewing angles;
- Working voltage indicator (220V or 12V);
- Relay contact type (open or closed);
- At what temperature and humidity they are able to work (especially important if it is selected for work outdoors or in rooms with a high level of moisture);
- Range of action.
The simplest and most affordable detectors are devices that work thanks to infrared radiation. However, it should be noted that microwave sensors are more reliable in terms of performance. Combined detectors are used to protect important objects.
Review of the best manufacturers
Which company is the best device, how much do they cost, which model is better to buy? On the market you can find a large number of motion sensors for signaling from a wide variety of manufacturers. Among buyers, inexpensive, budget models are very popular, which can be bought on the website and AliExpress from China or ordered online at domestic sites. The most popular manufacturers of motion sensors that are found on the domestic market are:
- Hager. Devices produced under this brand have the best quality level and affordable price. They are equipped with a special twilight switch function, so that they can be configured for different operating modes (operation during the day or at night).
- Theben. The models produced under this series are equipped with a high-quality reliable mechanism and also stand out for their modern design. They have good functionality and reasonable cost.
- Schneider Electric. A popular worldwide French manufacturer of electrical equipment. Engaged in the production of wiring and cable support products.
Best Motion Sensors for Alarm for 2020
Motion sensors are small-sized devices, so their installation can be carried out in almost any hidden place. However, it should be noted that the more powerful such a device will be, the greater will be the indicators of its dimensions.
When choosing a detector for your alarm system, you need to take into account the fact that infrared models, during operation, give the highest percentage of false alarms. However, their low cost and availability easily compensates for this disadvantage.
Devices that work thanks to microwave radiation have a bad effect on the state of living organisms. However, the advantage of such devices is that, during their operation, they are able to monitor spaces that are behind various obstacles. The most effective option for signaling is the use of combined detectors.However, their disadvantage is their high cost, weight, and size.
