Shenzhen 5.8g radar sensor module face recognition access control system control automatic door microwave radar technology

2022-03-04 1084

Shenzhen 5.8g radar sensor module face recognition access control system controls automatic door microwave radar technology, intelligent face recognition access control system microwave radar sensor module induction control plan starts with energy saving, environmental protection and intelligent induction. When someone walks past, it can intelligently sense the presence of the human body. The Shenzhen 5.8g radar sensor module wakes up the screen and turns on the screen. It automatically turns off when there is no one with low power consumption at the ua level. The face recognition access control system collects face information through the camera. Compared with the huge face template in the background, it is confirmed that the residents of the community or floor can pass freely. That way, even if you go out and forget your magnetic card, morphed fingerprint, and password, you won't be blocked at the gates of the community. The income and expenditure of "face brushing" is more convenient, safe and hygienic.

Face access control uses face recognition technology to create "keys" for access rights in the access control system in places such as enterprise parks and government office buildings. By comparing the captured face with the pre-input face database, the special "card" of the face can be used to judge the access rights of different areas, different access points and different time periods, and control the opening of the access control system in the building. Mainly based on face recognition control equipment. On the basis of the face, IC cards, fingerprints and other methods are allocated for combined verification to further strengthen and ensure security.


The automatic induction door adopts Shenzhen 5.8g radar sensor module, the difference between microwave radar technology and infrared sensor


Automatic doors are often found in places like hotels or banks. When someone approaches, the door will automatically open to both sides, and the back door will automatically close when someone walks past. So how does the automatic door realize automatic opening and closing?


The realization of the automatic induction door function is mainly related to the main controller, the induction detector, the power motor and the door leaf running track. Today, we mainly introduce the induction detector in the automatic induction door. Mainly responsible for collecting external signals, divided into microwave radar and infrared sensors.


Shenzhen 5.8g radar sensor module microwave radar technology


Functional principle: Microwaves are electromagnetic waves, such as those emitted by radio transmitters, but at higher frequencies (>1GHz). Thanks to the variable antenna, the microwaves emitted by the transmitter can be guided without difficulty by the reflectors from floors, walls and other surfaces.


If the monitoring area does not move, the frequencies of the transmitter and receiver will remain the same - the area is clean. However, when people and objects move through the monitored area, the motion detectors will be activated and the frequencies of transmission and reception will no longer be the same. The difference between the frequencies is evaluated and transmitted in the form of switching pulses via relays or electronic contacts. Microwave radar technology is safe for humans and animals.


Active Infrared Sensor Technology


Functional principle: Active infrared detectors always consist of a transmitter and at least two receiver chips with high-quality optics. The scanning range is set by a mechanical microspeed device by changing the angle between the transmitter and receiver. This optical procedure is called triangulation or optical difference measurement.


Active infrared detectors are static and only detect when people and objects interrupt the beam. The detection area consists of spots, which are mainly determined by the optical center distance between the transmitter and receiver lenses. Several beams can be combined into a modular system to create a larger area.


How are automatic sensing doors immune to interference? In addition to known influencing factors such as rain, snow, fluorescent lights, and fundamental vibrations of door drives, there is an increase in interference caused by radio and x-ray equipment. Optimized circuits and other suppression components can provide Extensive protection.


Today, more special features, environmental awareness, energy and cost savings are no longer just an empty promise. Here are some of the functions available: Distinguish between direction and motion away from the detector, and some known models can even distinguish between cross-traffic and approaching traffic. The separation between man and car will make the door different from man. Using an easy-to-use remote to set up the sensor is now standard. There are two models on the market: one-way, where settings are read by a flashing LED on the count sensor; or two-way remote, where you can read settings and display them visually on the remote.
