RF anti-theft device system is a kind of 8.2MHZ RF radio frequency skills. It is generally used in supermarket anti-theft and clothing anti-theft. The appearance of the product is generally composed of aluminum alloy and plastic shell. Corresponding 8.2Mhz consumable labels can be used as supermarket anti-theft.
What are the advantages and disadvantages of RF anti-theft device system? First, the cost of the radio frequency immobilizer system is relatively low, and the complexity of the circuit board planning is relatively less complicated. Secondly, the equipment of the radio frequency immobilizer system is slightly more complicated. A certain device experience is required to complete the installation, and then the radio frequency immobilizer. The system is relatively simple to be interfered with by some radio frequency equipment, it is simply shielded and then the ambition is not achieved.
The acousto-magnetic system is a resonance phenomenon generated by the tuning fork principle, which completes almost zero false alarms. When the frequency of the transmitted signal (alternating magnetic field) and the oscillating frequency of the acousto-magnetic tag are common, the acousto-magnetic tag is similar to a tuning fork and will cause resonance to generate a resonance signal (alternating magnetic field); when the receiver detects 4-8 consecutive times (adjustable) ) After the resonance signal (every 1/50 second), the receiving system will give an alarm. The acoustic and magnetic anti-theft device system uses the skills of 58khz. Related to the radio frequency anti-theft device system, it has a variety of appearances. There are relatively classic acrylic glass styles and ABS plastic styles. Demand matches the anti-theft consumables that you want to respond to.
What are the advantages and disadvantages of the acoustic magnetic anti-theft device system? The primary sound and magnetic anti-theft device system is more sophisticated and has a high alarm capability and sensitivity. In fact, the sound and magnetic anti-theft device system is not easy to be interfered by metal and is relatively stable. In terms of equipment, it is relatively simple and simple. It only needs to be connected to the power, and it can be used. Of course, the price will be a little more expensive than the RF anti-theft device system.
