Will there be an alarm when you take the clothing supermarket buckle picker through the security doo

No, nerd. The security door alarm relies on the hidden circuit inside the plastic parts that are removed with magnets. >>>More

Yes, the principle of the alarm is electromagnetic induction, and when the magnet passes through the anti-theft door, it will disturb the magnetic field of the anti-theft door, so it will generate an alarm. >>>More

There will be no alarm.

There are many situations of interference, such as high-frequency electrical appliances in the store, spotlights, light boxes close to the security door or the same frequency of the security door in the store next door, etc., in addition, if the label is too close to the security door, it will also be sensed. The solution should also be based on the situation at the time of the false alarm, observe the environment around the door, use the elimination method to find the cause, and non-professionals should not adjust the motherboard at the beginning. >>>More

It won't ring some people.

I took something from the supermarket, tore off the barcode, and then stole it out! >>>More

The police will be called.

Supermarket goods are generally equipped with two kinds of anti-theft devices, one is a small magnetic stripe, commonly known as "soft label", the other is a button type magnetic device, commonly known as "hard label", they are the use of magnetic induction principle to prevent theft, the alarm device at the door of the supermarket is also known as "anti-loss door", which is equipped with a magnetic sensor. If the product has not been demagnetized and passes through the damage prevention door, an alarm will be given. After the customer selects the goods and pays at the cash register, the cashier will degauss the goods with "soft label" and "hard label", if it is a "soft label", it will be demagnetized on the degauss on the cash register counter, and if it is a "hard label", a special tool will be used to hold the "hard label" from the product. >>>More
