AM and RF are two types of electronic article surveillance (EAS) systems used in retail stores to prevent shoplifting. AM systems operate at 58 kHz, while RF systems operate at 8.2 MHz. The main difference between the two systems is the frequency at which they operate.
AM systems are better suited for stores that sell items with metal components, such as clothing, electronics, and tools. This is because AM signals are less likely to be blocked by metal than RF signals. AM systems are also less susceptible to interference from other electronic devices. However, AM systems have a shorter detection range than RF systems.
RF systems are better suited for stores that sell small, high-value items, such as cosmetics, jewelry, and electronics. This is because RF tags are smaller and thinner than AM tags, making them easier to conceal. RF systems also have a longer detection range than AM systems. However, RF systems are more susceptible to interference from other electronic devices.
The best type of EAS system for your retail store will depend on the type of products you sell and the level of security you need. If you sell items with metal components, an AM system is a good option. If you sell small, high-value items, an RF system is a good option.
Here is a table that summarizes the key differences between AM and RF systems:
|Frequency||58 kHz||8.2 MHz|
|Susceptibility to interference||Less susceptible||More susceptible|
|Suitable for items with metal components||Yes||No|
|Suitable for small, high-value items||No||Yes|
Here are some additional factors to consider when choosing between AM and RF systems:
- Cost: AM systems are typically less expensive than RF systems.
- Installation: AM systems are typically easier to install than RF systems.
- Maintenance: AM systems typically require less maintenance than RF systems.
Ultimately, the best way to choose between AM and RF systems is to consult with a security expert who can assess your specific needs.
