We aim at providing utmost security at your office and retail stores by administering advanced EAS solutions. Electronic Article Surveillance system is used to prevent malpractices like shoplifting by attaching electronically detectable tag to the item. Detection antennas placed at store exits detects signals from active tags (tags which are not deactivated) and sets off an alarm.

Areas Of Application
Concealed EAS Systems
This recently popular advanced system is installed below the floor and dropped from the ceiling and has no visible pedestals or obstacles in the storefront. Such systems are highly demanded by shopping malls in view of enhancing the shopping experience.
Electro-magnetic System
Such systems use tags made of amorphous metal having very low magnetic saturation values, also lined by a strip of ferromagnetic material. The search is performed by detecting harmonics and signals generated by the material’s nonlinear magnetic response under mixing of magnetic fields.
Acousto-magnetic Systems
Such systems use tags formed from magnetostrictive, ferromagnetic amorphous metal and magnetically semi-hard metallic strips. The detectors produce periodic tonal bursts at a frequency same as the resonance frequency of the amorphous strips which leads to magnetostriction and causes longitudinal vibrations that continues even after the burst. Such
vibrations induces an AC voltage in the receiver antenna which activates the alarm when the required parameters are met.
Radio Frequency Systems
RF systems use tags which are LC resonant circuits.The detection is done by scanning the resonant frequency and sensing the dip. The most popular frequency is 8.2 MHz. 8.2 MHz tag label can be deactivated by partial destruction of the capacitor so as to detune the circuit
Microwave Systems
It make use of permanent tag made of diodes which acts as mixer that relay the combination of signals emitted from a microwave field emitted by a microwave antenna and a low frequency field emitted by an electrostatic antenna at the exit. This re-emitted modulated signal sets off an alarm.
