Device Debugging

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 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.

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.

  • Rising Edge means the signal transmission timing synchronizes along the rising direction of power common frequency. Falling Edge means the signal receiving timing synchronizes along the falling direction of power common frequency.
  • If there are still lots of false alarms after Phase Synchronism, you can adjust the phase manually in System Settings.

FAQ

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

 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.  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.

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

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

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

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

4. Irregular occasional false alarms.

 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.  Solution: Place devices with the EAS tag outside the detection range of the EAS antenna as required.  Reason 2: There is a similar coil near the EAS antenna to form a loop, generating the tag signal.  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.  Reason 3: There are other electrical equipment connected to the EAS exclusive circuit, and then the power interference leads to false alarms.  Solution: Check whether any electrical equipment is mistakenly plugged into the EAS exclusive circuit. If there is, please remove it.  Reason 4: There are other EAS devices suppliers installing and debugging in other nearby stores, and the unsynchronized phase of EAS devices causes false alarms.  Solution: Please communicate with the store, and ask their EAS equipment supplier to stay in the store to observe after the installation and debugging to ensure that the EAS device has been synchronized without interference with each other.  Reason 5: The newly added electrical device in the store is near the EAS antenna, and spatial interference leads to false alarms.  Solution: Before the store needs to add new electrical device near the EAS antenna, please temporarily power on the device to test whether it will cause interference to the EAS antenna. Please contact the technician to confirm whether it can be installed

5. The label detection rate is low, and no alarm is sent through the antenna area.

Appendix 1 Cybersecurity Recommendations

Mandatory actions to be taken for basic device network security:

  1. Use Strong Passwords
    Please refer to the following suggestions to set passwords:
     The length should not be less than 8 characters.
     Include at least two types of characters; character types include upper and lower case letters, numbers and symbols.
     Do not contain the account name or the account name in reverse order.
     Do not use continuous characters, such as 123, abc, etc.
     Do not use overlapped characters, such as 111, aaa, etc.

  2. Update Firmware and Client Software in Time
     According to the standard procedure in Tech-industry, we recommend to keep your device (such as NVR, DVR, IP camera, etc.) firmware up-to-date to ensure the system is equipped  with the latest security patches and fixes. When the device is connected to the public network, it is recommended to enable the “auto-check for updates” function to obtain timely information of firmware updates released by the manufacturer.
     We suggest that you download and use the latest version of client software.

“Nice to have” recommendations to improve your device network security:

  1. Physical Protection
    We suggest that you perform physical protection to device, especially storage devices. For example, place the device in a special computer room and cabinet, and implement well-done access control permission and key management to prevent unauthorized personnel from carrying out physical contacts such as damaging hardware, unauthorized connection of removable device (such as USB flash disk, serial port), etc.

  2. Change Passwords Regularly
    We suggest that you change passwords regularly to reduce the risk of being guessed or cracked.

  3. Set and Update Passwords Reset Information Timely
    The device supports password reset function. Please set up related information for password reset in time, including the end user’s mailbox and password protection questions. If the information changes, please modify it in time. When setting password protection questions, it is suggested not to use those that can be easily guessed.

  4. Enable Account Lock
    The account lock feature is enabled by default, and we recommend you to keep it on to guarantee the account security. If an attacker attempts to log in with the wrong password several times, the corresponding account and the source IP address will be locked.

  5. Change Default HTTP and Other Service Ports
    We suggest you to change default HTTP and other service ports into any set of numbers between 1024–65535, reducing the risk of outsiders being able to guess which ports you are using.

  6. Enable HTTPS
    We suggest you to enable HTTPS, so that you visit Web service through a secure communication channel.

  7. MAC Address Binding
    We recommend you to bind the IP and MAC address of the gateway to the device, thus reducing the risk of ARP spoofing.

  8.  Assign Accounts and Privileges Reasonably
    According to business and management requirements, reasonably add users and assign a minimum set of permissions to them.

  9. Disable Unnecessary Services and Choose Secure Modes
    If not needed, it is recommended to turn off some services such as SNMP, SMTP, UPnP, etc., to reduce risks.
    If necessary, it is highly recommended that you use safe modes, including but not limited to the following services:
     SNMP: Choose SNMP v3, and set up strong encryption passwords and authentication passwords.
     SMTP: Choose TLS to access mailbox server.
     FTP: Choose SFTP, and set up strong passwords.
     AP hotspot: Choose WPA2-PSK encryption mode, and set up strong passwords.

  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.

  13. Construct a Safe Network Environment
    In order to better ensure the safety of device and reduce potential cyber risks, we recommend:
     Disable the port mapping function of the router to avoid direct access to the intranet devices from external network.
     The network should be partitioned and isolated according to the actual network needs. If there are no communication requirements between two sub networks, it is suggested to use VLAN, network GAP and other technologies to partition the network, so as to achieve the network isolation effect.
     Establish the 802.1x access authentication system to reduce the risk of unauthorized access to private networks.
     Enable IP/MAC address filtering function to limit the range of hosts allowed to access the device.
