The equipment of the anti-theft alarm system is  generally divided into: front-end detector, alarm controller.  The alarm controller is a host (like the host of a computer), which is used to control the processing of wired/wireless signals, the detection of system failures, the power supply, signal input, signal output, built-in dialer, etc. The alarm controller is indispensable in an anti-theft alarm system. Front-end detectors include: door magnetic switch, glass break detector, infrared detector and infrared/microwave dual discriminator, emergency button.

The anti-theft alarm system refers to a device that causes an alarm when an illegal intrusion into the prevention zone occurs. It is used to signal the occurrence of a dangerous situation. The anti-theft alarm system uses detectors to arm important locations and areas inside and outside the building. It can detect illegal intrusion in time, and promptly warn relevant personnel when it detects an illegal intrusion. For example, door magnetic switches, glass break alarms, etc. can effectively detect intrusion from outside, and infrared detectors can sense the activities of people in the building. Once an intrusion occurs, the time and location of the intrusion can be recorded in time, and an alarm signal can be sent out through the alarm device.

Magnetic switch: 

The door sensor switch is composed of a dry reed switch and a magnetic strip, which can be divided into wired/wireless door sensors. Generally used in doors and windows. As long as the distance between the magnetic strip and the reed tube is less than 20mm, there will be an alarm signal output.

Glass break detector:

The glass break detector uses the piezoelectric effect of the piezoelectric ceramic sheet (the piezoelectric ceramic sheet will generate electric charge on its surface when it is twisted and deformed under the action of external force), and can be made into a glass break intrusion detector. Effective detection of high-frequency glass breaking sounds (10k～15kHZ), and strong suppression of sound signals below 10kHZ (such as speaking and walking). The frequency and intensity of glass breaking acoustic emission are related to the thickness and area of the glass. According to the different working principles, glass break detectors can be roughly divided into two categories: one is a voice-activated single-technology glass break detector, which is actually a frequency-selective function (bandwidth 10 to 15KHz) with a special purpose ( A sound-activated alarm detector that can drive out the high-frequency signals generated when the glass is broken. The other type is dual-technology glass break detectors, which include voice-activated-vibration type and infrasound-glass-breaking high-frequency sound type. It is generally applicable to ATM machines of banks, and other glass is anti-damage.

Infrared Detectors:

Infrared detector is a kind of radiant energy converter, which is mainly used to convert the received infrared radiant energy into electric energy, heat energy and other forms of energy that are convenient for measurement or observation. According to the energy conversion method, infrared detectors can be divided into heat detection There are two types of photon detectors and photon detectors. The working mechanism of thermal detectors is based on the thermal effect of incident radiation causing a change in a certain electrical characteristic of the detector, while photon detectors are based on the photoelectric effect generated by the interaction between the incident photon stream and the detection material. Specifically, the detector responds to the change in the number of free carriers (i.e., electrons and/or holes). Since this change is caused by the change in the number of incident photons, the response of the photon detector is proportional to the number of absorbed photons. The response of the heat detector is proportional to the energy absorbed.

-Infrared & Microwave Detector with Intelligent anti-pet functions.

They have a wide range of applications, such as infrared alarms installed indoors, which will output signals as long as there are people or moving objects.

Smoke & Heat detector

The energy conversion process of thermal detectors includes: thermal resistance effect, thermal volt effect, thermopneumatic effect and pyroelectric effect. The energy conversion process of photon detector includes: photovoltaic effect, photoconductive effect, photoelectromagnetic effect and light emission effect.

Emergency button:

Emergency button: It is a relatively simple device among anti-theft devices. It is a switch. There is a normally open/closed output, and when the switch value changes, it will output an alarm signal to the host.

Indoor / Outdoor Strobe Siren:

- Alarm indicator:

Alarm indicator light: It is an output device. When the alarm host processes the output to be processed by the alarm signal, the connected alarm indicator light will work.

- Audible alarm:

When the alarm host receives the alarm signal, it will output it through the sound and light alarm. At this time, the sound and light alarm will flash and buzz at the same time.
