How is the security door of the supermarket burglar proof?

What 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.

Supermarket anti-theft and anti-theft system composition and working principle:

The supermarket anti-theft system is divided into three major components, which need to be used to achieve the anti-theft effect.

1.Anti-theft sensor door (used to read the electromagnetic wave of the anti-theft tag).

2.Anti-theft tag: divided into two kinds of hard tags and soft tags (with wireless magnetic waves, when there is no demagnetization or unlocking through the induction door, it will be recognized by the anti-theft 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.

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 tags and soft tags (with wireless magnetic waves, when there is no demagnetization or unlocking through the induction door, it will be recognized by the anti-theft 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).

The anti-theft door is completed in several steps, the first it must have a sensor, and the second is that its magnetic field should be matched with the supermarket's anti-theft, if the magnetic buckle is not balanced with the body of the slide, even if someone takes out something, he will not have an induction.

The anti-theft door of the supermarket is very functional, most of them are inducted by artificial intelligence, and the goods that have not been paid by scanning the code will be inducted.

This is the interconnection between the Internet and surveillance.

Each has its own system, and the different functions displayed in the installation are different, and the specific situation should be decided according to their own.

There is an alarm connected to it, and abnormal means will trigger the alarm to play the role of anti-theft!!

You'll find out if you go and try it secretly in the middle of the night.

I don't know about this and this! Yikes! I don't know about this! I don't know about this! I don't know about this! I don't know about this! I don't know about this! I don't know about this!
