4	Storage battery in	Connects to a 12 V SLA battery.

Function of the UPS Board

The SLA battery is connected to the host box through the port 1. When port 3 is connected to 12 V power supply, the UPS board supplies the 12 VDC power to the host box, and at the same time charges the SLA battery through port 4.

When the 12 VDC power of port 3 fails, the UPS board immediately switches the DC power of the SLA battery to discharge mode and supplies power to the host box. The host box accesses whether the battery is connected, charging or discharging through the data port (port 1).

Battery Requirements

Must be a 12 V SLA battery. No capacity limit.

Battery Charging Time

The constant charging current is 500 mA, so the charging time is: h = C / 500 mA × 1.2.

Assuming the capacity of a SLA battery is 2 Ah, its charging time will be: h = 2 Ah / 0.5 A× 1.2 = 4.8 h.

SLA Battery Life

• Capacity of the SLA battery: C. Unit: Ah
● Power consumption of the Detector: Min: 15.5 W; Max: 26.5 W
• Voltage of the Detector: 12 V
Assuming the capacity of the SLA battery is 7 Ah, the battery life will be:
- Min: H = C / A = C / (P / U) = 7 / (26.5 / 12) = 3.17 h
- Max: H = C / A = C / (P / U) = 7 / (15.5 / 12) = 5.42 h

3.2 Environmental 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 Detector 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 7 Adjust the camera to a suitable angle.

3.5 Multiple Walk-through Site Installation

When installing multiple devices, space the devices at least 50 cm, and also space the device and X-ray 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.

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.
