Anti-theft alarm: Who will become the market for the main battlefield in the future

The broad security alarm system can be divided into professional security alarm systems and intrusion alarm systems. Professional security alarm system refers to the alarm system used by certain specialized industries to prevent accidents or accidents that may jeopardize the safety of people and property. For example, fire alarm, anti-poisonous and harmful gas leak alarm, anti-chemical substance leak alarm, and anti-radioactive material leak alarm.

The intrusion alarm system can be further divided into the anti-theft and anti-illegal intrusion alarm systems of enterprises and public institutions according to actual needs and different alarm functions. It is mainly applicable to the integrated networked alarm system, home security alarm system, and application in the transportation of residential quarters and households. There are four anti-theft and anti-illegal intrusion alarm systems in the car anti-theft alarm system.

The anti-theft and anti-illegal intrusion alarm systems for enterprises and institutions are mainly used for anti-illegal intrusion alarms in enterprises, institutions, factories, material warehouses, financial institutions, business establishments, supermarkets, shopping malls, institutions, and key security units and high security level locations. The residential integrated networked alarm system integrates the home security alarm system and the perimeter alarm system. It uses a set of alarm management center equipment and alarm management software to uniformly manage the home security alarm system and the perimeter alarm system.

At present, the development of the alarm service industry has been further standardized, and the civilian market has gradually become the main force. Faced with increasingly higher requirements of the market and the environment, anti-theft alarm manufacturers have also been striving to carry out technological innovation and market development in addition to satisfying the basic requirements of reliable and stable products. After years of technology accumulation and market cultivation, especially the popularization and application of Internet technologies and wireless communication technologies, the further improvement of social security awareness has had a profound impact on the burglar alarm industry. Anti-theft alarm products are rapidly advancing towards networking and integration, and the civilian market has started. The business model of the alarm vendors is steadily moving toward providing products and services.

Electronic anti-theft alarm equipment can be classified as follows:

1, according to the different types of sensors can be divided into switch alarm, vibration alarm, voice alarm, infrared alarm, microwave alarm, laser alarm, video motion alarm, smoke alarm, temperature alarm and so on.

2, according to different ways of working, can be divided into active alarm (such as infrared detectors) and passive alarm (such as indoor infrared detectors).

3. According to different installation methods can be divided into: wall-mounted detectors, ceiling-mounted detectors, mounted detectors.

4, according to different alert range, can be divided into point, line, surface and space detection alarm. The point intrusion detectors include:

1) Switch intrusion detectors - magnetic gate, magnetic gate, etc.

2) Vibration intrusion detectors - vibration detectors, glass break detectors, etc.

Linear intrusion detectors include (738607852);

1) Infrared intrusion detector. It can be further subdivided into passive infrared detectors, which do not need to send signals to the detection site during work, but rely on the energy of the measured object itself to detect, such as indoor or outdoor passive infrared detectors; active infrared detectors - when working Some form of energy needs to be sent to the detection site, and a stable signal is formed on the sensor by reflection or direct radiation. When a dangerous situation occurs, the stable signal is destroyed and the signal is processed to generate an alarm signal. Such as infrared detectors on the radio, the radio detector detection distance is generally 30m, 60m, 80m, 100m, 150m, 200m (are installed in the outdoor installation detection distance) and several other files.

2) Laser intrusion detector.

The principle of the alarm is the same as that of infrared radiation detection. It is also the use of the blocking alarm function. The equipment works better in stability, but the cost is higher.

Surface intrusion detectors include:

1) Curtain detector - suitable for alerting small areas (such as windows, balconies, etc.).

2) Sensing cable - buried installation, which can change with the perimeter of the area to be guarded, forming an invisible wall, suitable for the prevention of the perimeter of a large area or complex terrain. It includes several types of vibration cables, body-sensing cables, and leaky cables.

3) Electronic fence. Electronic fences include both pulsed and electrostatic induction types.

Spatial intrusion detectors include:

1) Sound intrusion detectors (sound detectors) - devices that detect sounds such as speaking and walking. Acoustic Emission Detector - A device that emits an intrinsic sound when the object is detected (such as glass, chisel, sawing steel) and is called an acoustic emission device.

2) The microwave intrusion detector detects the movement of the intruding object using the principle that the microwave is easily reflected by the object. Some detectors use infrared and microwave technologies for detection. They are called infrared/microwave dual-mode detectors. The detectors usually have a detection range of 5 to 20 meters, an angle of about 90 to 110 degrees, and an installation height of 2.1 meters. ~2.3m.

3) The video motion detector uses a camera as a detector to monitor the protected space. When a target enters the defense area, it sends an alarm signal through intelligent analysis.
