Hypermarkets prevent theft with AM frequency security gates

Theft and fraud are common occurrences in hypermarkets and shopping malls. With thousands of customers entering and exiting daily, manual merchandise control becomes inefficient. AM frequency security gates offer an automated control solution, detecting unpaid items before they leave the store.

EAS (Electronic Article Surveillance) is a technology that attaches magnetic tags to merchandise. If a tag is not removed at the checkout counter, it triggers an alarm at the security gate. AM (Amplitude Modulation) frequency operates at 58 kHz, unlike RF (Radio Frequency) at 8.2 MHz, making it suitable for large-scale retail supermarkets.

##What are AM frequency security gates and how do they work?

AM frequency security gates are a system of two transmitter-receiver columns operating at 58 kHz, installed at supermarket exits. When a customer passes through the gate with an unremoved EAS tag, the magnetic wave activates the tag, triggering an audible and visual alarm. The system can detect tags from a distance of 1-2 meters, with 95-98% accuracy.

An AM security gate consists of two main columns: a transmitter and a receiver. The transmitter continuously emits magnetic waves at 58 kHz, while the receiver listens for feedback signals from the tag. When an EAS tag passes through the detection zone, it absorbs magnetic wave energy and re-emits a characteristic signal, which the receiver identifies and triggers an alarm. Detection time is < 0.5 seconds, without affecting customer experience.

##Why should hypermarkets choose AM frequency security gates?

AM frequency security gates have 20-30% lower installation costs than RF, with stable detection in crowded supermarket environments. AM technology is not interfered with by other electronic devices, making it suitable for high-traffic supermarkets. It reduces merchandise loss by 30-50% compared to having no system, with an ROI within 12-18 months.

According to Việt POS's experience in deploying at hypermarkets ranging from 2000-5000 m², AM security gates help reduce theft rates from 2-3% to 0.5-1% of revenue. Security personnel can focus on other areas instead of blocking exits. EAS AM tags cost 500-1500 VND/piece, which is 30-40% lower than RF tags, and are easily replaced when merchandise is sold out.

##Popular AM frequency security gate models in Vietnam

The AM security gate market in Vietnam is primarily served by vendors such as ZKTeco, Hikvision, Suprema. Below is a comparison table of popular models:

The ZKTeco D1065 model is suitable for small-scale retail stores (< 500 m²), with 6 detection zones and 95% accuracy. The D2180 model is a standard choice for hypermarkets (1000-5000 m²), with 18 detection zones, detecting tags from a distance of 2 meters. The D3180S model combines a security gate with body temperature measurement, suitable for supermarkets requiring health control after an epidemic.

##Cost of installing AM frequency security gates for supermarkets

The cost of installing AM security gates includes: gate equipment 15-40 million, EAS tags 500-1500 VND/piece, installation + configuration 2-5 million, staff training 1-2 million. The total cost for a 2000 m² supermarket is 40-80 million, with an ROI within 12-18 months if losses are reduced by 30-50%.

Việt POS provides a comprehensive installation package: free survey, system design, equipment supply, installation, configuration, and staff training. There are no hidden costs, with a 24-month warranty and 24/7 technical support. Customers can choose to pay a lump sum or spread payments over 12-24 months.

##Deployment process for AM frequency security gates in supermarkets

Việt POS implements AM frequency security gates according to a standard process:

1. Site survey: measure supermarket exits, determine gate installation locations, check electromagnetic environment.
2. System design: determine the number of gates, type of EAS tags, and layout for optimal detection.
3. Equipment supply: deliver security gates, EAS tags, cables, power supply, auxiliary equipment.
4. Installation + configuration: install gates, connect power, configure frequency, test sensitivity.
5. Staff training: instruct on EAS tag removal, alarm handling, daily maintenance.
6. Warranty + support: 24-month warranty, 24/7 technical support, free repairs.

##AM frequency security gates versus other control solutions

The supermarket merchandise control market offers various solutions: AM security gates, RF security gates, AI cameras, and security personnel. Below is a comparison table:

AM frequency security gates are a balanced choice between cost and effectiveness for medium-sized retail supermarkets. If a supermarket requires over 99% accuracy or tag detection from > 2 meters, RF gates should be chosen. If video recording + customer behavior analysis is needed, combine AI cameras with AM gates.
