Rating of the best motion sensors for alarms for 2020

Motion detectors are capable of covering and keeping under observation vast spaces, which is why they are widely used to protect premises of various types - residential, industrial premises, shopping malls, educational institutions and other facilities and enterprises. The motion sensor is an integral part of security alarms, has a moderate cost, easy to install and operate. The detectors do not require constant maintenance, while they are able to operate continuously for a long time.

The design of the device allows you to cover a large sector, depending on the range, vertical and horizontal viewing angles. If a moving object enters the area monitored by the detector, a relay is triggered, which in turn triggers an alarm - a siren sound, a searchlight is turned on, an alarm signal, and in certain cases, a striking device is launched.

Types of motion sensors

Manufacturers offer many different modifications of this type of equipment, performing one function, but differing in their principle of operation.

1. Infrared (thermal).
2. Ultrasonic (acoustic).
3. Microwave (radio frequency).

Thermal, or infrared, sensors have a high sensitivity PIR sensor capable of instantly detecting infrared radiation from an animal or person. The angle of the detection zone of a moving object reaches 120 degrees, the range is from 10 to 15 meters.

• the ability to adjust the sensitivity;
• affordable cost;
• the product is completely safe for children and animals.

• reacts to inanimate warm objects (heating and lighting devices), as well as to pets and simply to the sun's rays.

Ultrasonic, or acoustic detectors, in their principle of operation, resemble a sound locator. Sound vibrations, inaccessible to human hearing, emitted by the generator, are reflected from moving objects. After that, the vibration frequency changes. Due to the difference in frequencies arriving at a special receiver, a signaling device is triggered.

• high sensitivity;
• quick response.

• small radius of the detection area;
• the product is not recommended for use in rooms where pets are present - sound vibrations are available for perception by animals.

Microwave or radio frequency detectors work the same way as acoustic ones (Doppler effect), but in this case, the generator transmits microwave radiation, not sound. When the frequency of the radiation reflected from the detected object changes, an additional device is triggered.

• covers large spaces;
• high sensitivity - the device is able to detect a moving object through a wall.

• the appliance consumes a lot of energy.

Motion detectors designed for perimeter protection are somewhat different in technical design from those listed above. The design of such sensors is highly reliable, capable of continuous operation regardless of weather conditions and air temperature. These detectors are immune to external interference and rarely show false alarms. The monitored space can have a complex configuration, a large area, or consist of several sections of different areas, therefore, detectors of the following types are used to protect such territories:

• Seismic;
• Infrared;
• Magnetic;
• Laser, or beam.

Seismic detectors record soil vibrations, vibration that is generated during the movement of a person or animal. The devices are used in certain natural and temperature conditions - the frozen ground makes it difficult for devices of this type to work.

Infrared are popular and widespread due to their low price, strength and durability of the structure, as well as ease of installation. Adjustment of IR detectors allows you to increase or decrease the sensitivity of the device, as well as to limit or completely prohibit the response to objects with a small weight and a small mass.

Magnetic devices record changes in the magnetic field in the controlled area. But, due to their low sensitivity, devices of this type are of low popularity.

Laser (beam) detectors have proven to be the most reliable devices. The construction of outdoor laser detectors consists of a transmitter and a receiver, and the beam is invisible to the naked eye. When an object crosses the laser beam, the receiver detects its disappearance, after which an alarm is triggered.

Laser beams pass through several levels at once, they cannot be seen, which means that it is impossible to pass unnoticed through such a sensitive and complex security system. Laser detectors operate over long distances between transmitter and receiver (on average 200 meters). The device is configured to exclude alarms for insignificant short beam interruptions that can be caused, for example, by falling leaves.

Also, it is worth taking a closer look at autonomous (wireless) IR motion sensors. Detectors of this type are an independent security device used when it is impossible to install a standard security alarm. Such a device is powered by a battery, and communication with the main device occurs via a radio channel.

Stand-alone sensors are multifunctional, easy to install, and capable of transmitting signals over long distances. Such a device can be placed anywhere in the room, without worrying about hiding the cable lines, as is the case with wired detectors. Therefore, such a device is suitable for monitoring rooms, the design of which must not be disturbed. Also, autonomous devices are suitable for the protection of small premises, for example, for a garage, a summer residence, a garden house.

Also, the stand-alone sensor has a connector for connecting an additional device, for example, a magnetic contact sensor that detects the opening of the door. Complex models of wireless detectors can be additionally equipped with the following:

1. GSM module - sends an SMS message to the owner of the protected premises;
2. Temperature detector - acts as a fire detector;
3. Siren - loudly announces an invasion;
4. Microphone - allows you to listen to the protected area;
5. Photo or video camera - make photo and video filming, allow for covert surveillance of the room.

There are indoor and outdoor wireless motion detectors. The latter have a durable, sealed body, reliably protected from negative environmental influences (rain, snow, fog, low and high temperatures). Outdoor units are usually mounted on the swivel brackets that come with the main unit. This mount allows you to choose the best viewing angle.

How to choose a motion sensor?

Equipment for the protection of premises must comply with the conditions of the controlled space:

• infrared sensors are suitable for the protection of an apartment, house or office;
• for the room in which material values ​​are stored, it is recommended to install a combined device - an IR sensor and a microwave in a single housing. This combination increases the security of the guard;
• to control a small perimeter (for example, private households), it is recommended to use a linear IR sensor. A security system of this type has a low cost, but demonstrates high efficiency.

When installing motion sensors, it is recommended to follow the instructions attached to the product and other technical documentation. It is worth noting that most devices are mounted at an angle, between walls, the mounting height is usually from 180 to 220 cm. Swivel brackets allow you to adjust the most effective angle of view of the territory. Indoor sensors must be installed so that the field of view covers all areas of possible intrusion (windows and doors).
