The following is a new security alarm manufacturers for everyone to introduce in detail, the current use of the industry's most widely used anti-theft alarm products: infrared alarm!
working principle
Infrared alarm is a kind of instrument that judges whether someone intrudes by detecting or receiving infrared rays. It mainly consists of an alarm host and infrared detectors. According to the principle of infrared alarm, it can be divided into active and passive infrared alarms.
Active
The active infrared alarm consists of two parts: transmitter and receiver. Among them, the transmitter includes a power supply, a light source, an optical system, and the like. Under the action of the power source, the infrared light emitting diode emits an infrared beam, which is converted into parallel light by the optical system. The receiver includes optical system, amplifier, optical sensor, signal processor and other components. It is responsible for receiving the infrared light emitted by the transmitter. The photoelectric signal converts the optical signal into an electric signal, which is analyzed by the signal processor and transmitted to the alarm control. Device.
Active infrared alarms use transmitters to emit infrared light, while receivers receive infrared light to work. An infrared alert line is formed between the transmitter and the receiver. Under normal circumstances, the transmitter emits infrared light, and the receiver receives a stable light signal. Once the alarm has been intruded in the area, the infrared beam emitted by the transmitter is blocked, and the receiver receives no longer a stable light signal, but changes to some extent. This change is transmitted after analysis and processing. To alarm controller so that it sends an alarm signal.
passive
Passive infrared alarm is based on the detection of external infrared energy to determine whether someone moves. People's body temperature is generally about 37 degrees, will release the infrared wavelength of about 10μm, this infrared energy is different from the surrounding environment, once the alarm detector in its area to detect the infrared wavelength of about 10μm, after analysis and processing An alarm signal will be issued.
The main process of the analysis and processing is that the infrared light emitted by the human body is first enhanced by the Fresnel filter, and then concentrated on the infrared sensor (usually a pyroelectric element) after being enhanced, and the pyroelectric element once receives the infrared light of the human body.
Advantage
1. Appearance: beautifully designed, compact, more in line with the needs of interior decoration.
2. Features: More powerful networking features, more convenient expansion.
3. Performance: stable, reliable, lightning protection, anti-blocking, anti-spray cover, anti-damage, etc.
4. Application: diversity, suitable for burglar alarm in home, office, warehouse, laboratory and other important occasions.
3. Operation: easy to install and disarm, user-friendly operation interface, easy to use.

* Wireless detectors and alarms are wirelessly connected and transmitted for high security.
* Arbitrary settings for arming and disarming.
* Remote intercom speaker function.
* The six zone mode types are set independently.
* Emergency assistance: When you need help, you can press the emergency button on the alarm to send a distress signal.
* Event Log: Record the most recent alarm event and operation settings.
* Simple and stylish appearance.
* Automatic telephone alarm, to provide remote users with alarms and on-site monitoring recording, and accept the user's instructions for appropriate operation.
* GSM alarm: With all the functions of the traditional telephone alarm, at the same time to send alarm messages to the user's mobile phone.
Supporting facilities:
(1) One host (2) One infrared detector (3) Two remote controllers (4) One wireless door sensor (5) One power supply (6) One siren
installation method
1, pillar: The detector is mounted on a square pillar, can be "1", "Z" or curved type, the pillar must be fixed and strong, which is conducive to defense and reduce false positives.
2. Wall type: The current active infrared detector manufacturer in the anti-theft market is able to provide an infrared detector with a 180° omnidirectional angle and a pitch angle of more than 20°. It can support the probe on the outer wall or wall of a building. , directly on the fence.
(Reference drawing, specific installation needs to install the user's location may be)
Precautions
1. Infrared detectors should not be installed outdoors, but only indoors.
2. Install the position as far as possible from the ground more than 2 meters, do not directly facing the glass doors and windows, avoid facing the windows, cold heaters, stoves and other temperatures will produce rapid changes in order to avoid false positives, but also try to avoid furniture, large bonsai or other Spacer.
3. Two infrared detectors cannot be installed in the same radiation range to avoid interference caused by simultaneous triggering.
4. The infrared sensor and the moving target of the monitored position are installed tangentially. After the installation is completed, the tilt angle is adjusted, a walking test is performed, the angle is adjusted to the best sensitive state, and the induction time short-circuiter is set to the normal alert state.
Note: When the infrared detector is just turned on, it has about 5 minutes of perception time for the surrounding environment. After the infrared detector is turned on for 5 minutes, it is then armed with the remote controller. When the intruder is detected by the infrared detector, it takes several seconds. The analysis of the clock confirms the time before it can send an alarm signal to avoid false alarms and missed reports.
In recent years, the Chinese government has accelerated the development of safe cities, the scale of the security market has continued to expand, and the demand for security products has also continued to increase. Its application has also led various industries with the advancement of science and technology and has opened up a whole new journey.
