The alarm device in front of the supermarket is equipped with a magnetic sensor. If the goods pass through the loss-proof door without degaussing, an alarm will be given.

A detector usually consists of a transmitter and a receiver. The basic principle is that the transmitting antenna emits a scanning frequency band, and a scanning area is formed between the transmitting antenna and the receiving antenna, and then the receiving antenna receives and restores the frequency band within its receiving range, and then uses the vibration principle of electromagnetic waves to search whether there are effective tags in a specific range, and triggers an alarm when effective tags appear in this area.

Extended data:

After the customer selects the goods at the cashier and pays, the cashier will degauss or deduct the money from the goods. If it is a "soft label", it will be demagnetized on the demagnetizer on the surface of the cashier. If it is a "hard label", special tools will be used to untie the "hard label" from the goods. In this way, the goods purchased by customers can safely pass through the alarm device at the entrance of the supermarket.

The internal structure of commodity electronic tag is an Lc oscillation loop, which is installed on the commodity in a special way and can only be released through a special decoder and lock opener. Electronic labels appearing in the market include soft labels, hard labels, wine bottle protective covers, milk powder anti-theft labels, CD/ tape protective boxes and so on.

Why does the alarm at the entrance of the supermarket call the police when someone takes something from the supermarket?

The principle of magnetic induction is generally to spray or paste magnetic things on commodities. The waiter will degauss when buying. If it is not eliminated, when the goods pass through the security door, the magnetic induction line will be cut in the magnetic induction area of the door, so that the current induction device of the door will be electrified and then the alarm will be given. At this time, the loss prevention personnel at the door will check according to your check-out receipt.
