Installation

3.1 Checklist
After receiving the product, check against the table below. If there are any problems, contact the after-sales service personnel.
Table 3-1 Checklist

Table 3-2 Packing list

3.2 Environment Requirements

• The ground is flat and sturdy
  The ground should be flat and firmly supporting to prevent vibration. If there is a vibrating metal structure under the ground, there can be unnecessary alarm when people pass through the metal detector.
  Do not install the detector on a metal ground.

• Keep away from fixed metal objects
  Large metal objects that are fixed or immobile should be at least 50 cm away from the detector (detecting large metal objects) because they might make the Device more susceptible to vibration.
  The distance in this section is the recommended distance. The actual installation distance depends on the installation site conditions.

• Keep away from moving metal objects
  Large moving metal objects should be kept 0.5 m to 2 m away from the detector to avoid false alarms. Depending on the size of the metal object, the distance between the moving metal object and the detector might vary.

• Keep away from radioactive electronic interference
  The distance between the electronic interference source and the receiving coil should be as large as possible. The recommended minimum distance is 0.5 m to 4 m. However, the actual distance needs to be based on specific circumstances. For example, you can go through a metal detector with a source of interference until the best position is found. Interference can occur from electronic control panels, radios and computers, image displays, high-power motors and transformers, AC wires, transistor control circuits, flash fluorescent tubes, arc welding equipment, and more.

• Keep away from conductive electronic interference
  Connect the power cable to a line that is not connected to other large loads, such as high-power motors, because they can cause a large power or voltage shock in the line.

3.3 Installing Detector
Step 1 Open the packing box and take out the accessories.
Step 2 Connect two DB25 cables and one power cable to the host box.

Step 3 Separately run the two DB25 cables through the two holes at the two ends of the beam.
Select one end of the beam, and run the power cable.

Step 4 Attach the host box to the front beam with four M6 × 50 cross pan head screws.

Step 5 Connect one end of the two DB25 cables and power cable to one detector panel, and then attach the front beam and rear beam to the detector panel with four M8 × 8 screws.

Step 6 Connect the other end of the two DB25 cables and power cable to the other detector panel, and then attach the front beam and rear beam to the detector panel with four M8 × 8 screws.

Step 7 Stand the Detector up.

Step 8 Connect the power supply to the Detector, and then turn on the power switch to start the Detector.

3.4 Multiple Walk-through Detectors Site Installation
When installing multiple devices, space the devices at least 50 cm, and also space the device and Xray security screening machine larger than 50 cm. This recommended spacing can make the little metal objects (such as coin) detected. If you install the devices with space smaller than 50 cm, there might be false alarm. If the spacing needs to be shorten because of limited installation site, you need to adjust the frequency, lower the security level and sensitivity according to the actual situation; otherwise, small metal objects might not be detected.

3.5 Stabilizing Detector
To make the Device work normally, stabilize the Device before use by tightening the fixing screws.

Appendix 1 Cybersecurity Recommendations

Mandatory actions to be taken for basic equipment 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 equipment (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 equipment 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 equipment network security:

1. Physical Protection
   We suggest that you perform physical protection to equipment, especially storage devices. For example, place the equipment 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 equipment (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 equipment, 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 equipment 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 equipment, 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 equipment 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.
