Anonymous users2024-01-23What is the principle of supermarket security door? Since ancient times, the role of the door is to keep out the cold, the other is anti-theft, in order to prevent theft, the door has been continuously strengthened from the wooden door to the anti-theft door, the anti-theft door can be very effective to protect their property, and the supermarket is particularly needed, the supermarket covers a wide area, only relying on the camera is not really anti-theft, so the supermarket also uses the anti-theft door, the supermarket's anti-theft door is not an ordinary door, so what is the principle of the supermarket's anti-theft door?
First, the principle of the radio system: the radio system uses radio waves as the signal transmitted and received, and the detection frequency range is megahertz. Radio signals of different frequencies are emitted.
The biggest advantage of the radio system is that the system cost is very low and it is easy to install. This is the first principle of the supermarket security door.
The second is the principle of electromagnetic waves: electromagnetic wave systems use electromagnetic waves as detection signals. His label is the smallest, the label price is also cheap, and it can be degaussed repeatedly, such as the one used in university libraries, but the system is prone to false alarms due to the influence of magnetic or metallic substances, which is the second principle of supermarket security doors.
The third. Acoustomagnetic principle: Tuning forks only cause resonance if they oscillate at the same frequency.
The acoustomagnetic principle is the application of this physical principle to achieve almost zero false alarm operation, when the acoustomagnetic system label fixed on the product enters the detection area of the system, the two will resonate, but only after the receiver receives four consecutive resonance signals, the alarm will be issued. The acousto-magnetic system is characterized by high anti-theft detection rate, almost zero false alarms, good anti-interference, and the protective outlet width can reach 35 meters, which is the third principle of supermarket security doors.
What is the principle of supermarket security door? I believe that after the above introduction, we have a certain understanding of this, we can choose according to the actual needs, friends who want to buy supermarket security doors can find their favorite products in Qeeka Home, and the price will also have an advantage.

Anonymous users2024-01-22Supermarket anti-theft and anti-theft system composition and working principle: The supermarket anti-theft system is divided into 3 major components, which need to be used to achieve the anti-theft effect: 1Anti-theft sensor door (used to read the electromagnetic wave of the anti-theft tag).
2.Anti-theft tag: divided into two kinds of hard tag and soft tag (with radio magnetic wave, it will be recognized by the anti-theft sensor door when there is no degaussing or unlocking through the induction door, thereby triggering the sound and light alarm of the induction door).
3.Degausser, (used to decode degaussing anti-theft soft labels), nail extractor (used to remove anti-theft hard labels on goods).
A complete set of anti-theft system, the above 3 points are indispensable, Huizhou Zhongqi Hongye can provide a complete set of solutions for free.

There are many supermarket immobilizer brands, imported sensors are generally used sensormatic brand, many manufacturers are in Shenzhen, Sai'an Vision series is very good, you can go to learn about it.
1. Detect the number of lock points and the anti-theft level of the lock. >>>More
How to judge the quality of the security doorThe general residents choose the main door as a thick security door when choosing the security door, and how to judge the quality of the security door is difficult for many consumers, judging the quality of the security door can start from the following four aspects. 1. Look at the thickness of the filling and steel plate can be seen when installing the anti-theft door, generally the cat's eye can be seen from the door to see what is inside, if there is a cat's eye has been installed, and it can not be screwed down, you can see when the door is locked. Consumers can knock on the anti-theft door with their hands, and the sound sounds solid, indicating that the thickness of the steel plate is enough, and the filling is real. >>>More
The simple distinction is the thickness of the door panel, but also on the anti-warping, lock technology unlocking time requirements, the door frame must be played above the "A, B, C, D" level words. Now the thief door panel will not go to warp, are the lock efforts, most of the brands of anti-theft door locks are the same, only Wang Li lock is more distinctive.
