4.1 Sensitivity Adjustment

• During the actual installation and use, the device detection effect is affected by the complex electromagnetic environment on site, and it is also difficult to accurately locate and close the interference sources. In order to deal with this situation, this Device designs a DIP system sensitivity adjustment switch, so that the device can be used normally under different interference intensity.
• For details on the switch, see "2.2 Port Description".
• By default, all switches are in lower state. At this time, the sensitivity is the lowest, the anti-interference capacity is the best, and the detection distance is the closest.
• DIP switch CH1A and DIP switch CH1B: Responsible for the sensitivity adjustment of CH1 channel (signal transceiver channel integrated on the mainboard). See Figure 4-1, when the switch 1 is pushed up, the antenna has the highest sensitivity and the signal amplification is the largest, which is suitable for low-noise environment. However, there is a certain risk of false alarms. If the site interference is large, the alarm source may not be detected, which is a normal phenomenon that the normal detection is interfered by the amplified noise. When switch 2 to switch 4 are pushed up successively, the sensitivity gradually decreases, and the detection distance gradually becomes shorter.
• DIP switch CH2A and DIP switch CH2B: Responsible for the sensitivity adjustment of CH2 channel (if CH2 is not connected, it cannot be adjusted). See Figure 4-1, when the switch 1 is pushed up, the antenna has the highest sensitivity and the signal amplification is the largest, which is suitable for low-noise environment. However, there is a certain risk of false alarms. If the site interference is large, the alarm source may not be detected, which is a normal phenomenon that the normal detection is interfered by the amplified noise. When switch 2 to switch 4 are pushed up successively, the sensitivity gradually decreases, and the detection distance gradually becomes shorter.
• DIP switch CH3A and DIP switch CH3B: Responsible for the sensitivity adjustment of CH3 channel (if CH3 is not connected, it cannot be adjusted). See Figure 4-1, when the switch 1 is pushed up, the antenna has the highest sensitivity and the signal amplification is the largest, which is suitable for low-noise environment. However, there is a certain risk of false alarms. If the

5.4.2 False Alarm Monitoring

Detect and display the false alarm numbers of each channel. You can check the false alarm numbers when debugging the device. Monitor for a period of time. If the number of a channel is big, it means there is interference in the environment or the alarm thresholds is not reasonable. You need to adjust the phase or configure the alarm thresholds of corresponding channel again.

5.5 Phase Synchronism

Phase synchronization can synchronize the transmission timing of the device with other EAS system, avoiding false alarms due to timing inconsistencies. For example, when the signal receiving timing of the device is same with the transmission timing of another device in the environment, then false alarms will be triggered. You need to synchronize the phase of the device.

Step 1 Select Phase Synchronism on the webpage.

Step 2 Click Rising Edge or Falling Edge. The phase will synchronize automatically.

6 FAQ

1. False alarms occur at fixed times every morning and evening.

2. Reason: Shopping malls and stores open in the morning, and then shut down and out of power at night, causing instantaneous voltage load imbalance and power supply interferences, resulting in false alarms.

3. Solution: This problem cannot be solved completely. Please turn on other electrical devices first in the store every day when opening the store, and then turn on the power of the EAS device last.

4. After the store is closed every day, an alarm is generated at night when no one is there.

5. Reason: In order to ensure the normal detection performance of the EAS device when the store is open, it is usually debugged according to the business environment. At night, the interference of the ambient power supply at night is reduced, and then the detection performance of the device is relatively improved. At this time, if there is an EAS label on the device near the EAS antenna, an alarm will be generated.

6. Solution: We recommend you turn off the power of the EAS device during closing time.

7. False alarms occur every few days, and then disappear after a few days without debugging. The phenomenon reoccurs.

8. Reason: Shopping malls regularly hold events, and the stage has temporary large electrical equipment, space and power interference, which leads to false alarms.

9. Resolution: Check the newly added electrical equipment during the false alarm period. After the interference source is determined by the elimination method, move the interference source away from the antenna.

10. Irregular occasional false alarms.

11. Reason 1: The clerk did not place the device with the EAS label outside the detection range, which was too close to the EAS antenna, resulting in a false alarm.

12. Solution: Place devices with the EAS tag outside the detection range of the EAS antenna as required.
13. Reason 2: There is a similar coil near the EAS antenna to form a loop, generating the tag signal.
14. Solution: Check if there are coiled wires or closed rings of metal forming loops near the EAS antenna that generate label signals and cause false alarms.
15. Reason 3: There are other electrical equipment connected to the EAS exclusive circuit, and then the power interference leads to false alarms.

Appendix 1 Cybersecurity Recommendations

10. Audio and Video Encrypted Transmission

If your audio and video data contents are very important or sensitive, we recommend that you use encrypted transmission function, to reduce the risk of audio and video data being stolen during transmission.

Reminder: encrypted transmission will cause some loss in transmission efficiency.

11. Secure Auditing

• Check online users: we suggest that you check online users regularly to see if the device is logged in without authorization.
• Check device log: By viewing the logs, you can know the IP addresses that were used to log in to your devices and their key operations.

12. Network Log

Due to the limited storage capacity of the device, the stored log is limited. If you need to save the log for a long time, it is recommended that you enable the network log function to ensure that the critical logs are synchronized to the network log server for tracing.
