The radio frequency system uses RF technology, with a center frequency of 8.2MHz and a modulated wave with a sweep width of about 1MHz, forming a stable electric field between the transmitter and receiver and placing it at the exit of the mall.
The radio frequency tag is composed of an inductor and a capacitor to form a resonant circuit with a frequency of about 8.2MHz. The label is attached to the protected product. When the stolen product with label enters the above electric field, the inductive coil of the resonant circuit induces a radio wave and resonates at the resonance point, causing an instantaneous change in the electric field. The change is detected by the receiver and an alarm is given.
