Dual Crossbar Frame Antenna Eas RF System Anti Shoplifting 8.2MHz
SZ-G930 RF 8.2MHz ReTAIL LOSS PREVENSSION EAS SECURITY SYSTEM
G930 based on the Dual crossbar frame antenna uses the new algorithms of digital filter and Powerful PIC
program controller instead the Antiquated SCM procedures to Achieve a stronger anti-interference
performance and higher sensitivity and automatic adaption to the environment function,which function
is far more better than the old system.The specific features are as follows:
1. In the design of the circuit,the main part and the core part use a completely new working model.The core part
apply newly High-speed PIC controller,coordinating Filtering algorithm with stringent procedures to achieve
accurate detection of the tag signal. This working model can Identify the tag’s signal,when the interference signal
and the tag’s signal are in the same intensity or even higher than the tags’s signal,which is determined by the
design of the circuit and program.This function can not be achieved with the old mother board.
2. Using precise frequency technology.Transmitting and receiving frequencies are scanned through rigorous
calculations and corresponds to the work.Scanning frequency from receiver if offset 0.1Hz will make the receiver
not alarm.this design when meet the same frequency interference from the other antennas in the same site,it will
automatically offset the frequency.with this function two sets of antennas in one site which distance is 3-5m will not
need to online installation.
3. The use of advanced PWM pulse modulation technique achieve a sensitivity of automatic control servo system.
This system In the spot according to interference on the interference signal acquisition and use PWM modulation
wave control sensitivity..this system can adjust the sensitivity automatically and can Maximum extent to avoid false
positives.the motherboard is easy to install and use,no need to adjust.
4. Advanced twice recognition function.This system can adopt the signal in a short time when it detect the still tags
around the antennas.the still tags will impact on the sensitivity of the system but will not cause false alarm.when
the tag is removed,the system will renew to the normal sensitivity.
5. The antenna adopts Luxurious and stylish brushed aluminum oxide , inserts 12cm imported crystal clear glass,
and inlays brushed aluminum oxide around the glass with delicate craft, Makes it the thickness antenna in the field
of EAS antitheft system.
Installation instance: when the system work in an Ideal electromagnetic environment,with soft label it is detection
range can reach 80cm-120cm and with hard tag it is detection range can reach 100cm-170cm.(in different environment ,the stander detection range will be different.)
