FAQ

PoC Power Supply
PoC XVR supports PoC function.

• PoC camera can be divided into AT camera and AF camera. Power consumption of AT camera is less than 12W, and power consumption of AF camera is less than 6W.
• You need to check the maximum power of PoC before use. Assuming that the maximum power of one XVR is 48W, the XVR can connect AT cameras up to 48/12=4 and AF cameras up to 48/6=8.
• When the device is in the condition of PoC power supply, do not connect any other device betweenthe device and PoC XVR or PoC transceiver such as UTC, Balun, optical transceiver, distributor and convertor and so on; otherwise, the device might get burned.
• PoC power supply is with high voltage. Do not dismantle the device during normal operation; otherwise it might cause danger to both device and users due to high voltage.

Long Distance Power Supply
In many scenarios, our clients adopt long distance power supply, transmitting 12V DC to cameras located over 100 m. Such long distance power supply might cause problems.

• Q1: Recurrent restart of devices or even ICR Failure.

  • Possible reasons: The long power supply cable leads to a large voltage drop on the equipment power supply cable, and turning on the IR light at night leads to a further increase of the voltage drop, resulting in restart of the device. After the device is restarted, the ICR is switched to the Day mode by default. By judging the ambient light at night, the device will operate in Night mode, and then the infrared light is turned on, which causes the device to restart again because of undervoltage. Thus, ICR is switched to every 2 seconds, impacting its switching lifespan.

• Q2: Unable to restart devices at night, and black screen or restart occurs when switching ICR.
  Possible reasons: The long power supply cable leads to a large voltage drop on the equipment power supply cable, and turning on the IR light at night leads to a further increase of the voltage drop, resulting in restart of the device and black screen.

  • Solution: During construction, when the camera location is far from the power supply, you need to adopt long distance separate power supply or purchase –DP dual power supply to use 24V AC power supply.

Centralized Power Supply
The typical problem of centralized power supply is that there are obvious black stripes on the device screen, which interferes with the display. The principle of centralized power supply is as follows: There are two paths for the power output of CAM4, return path 1 and return path 2. Reflow 2 first flows to CAM1, and then flows to the power supply from power supply ground of CAM1. In this way, the reflow of power supply ground CAM4 affects the video ground of CAM1, resulting in interference stripes on the screen. And CAM4 also interferes with CAM2 and CAM3. In the same way, CAM1, CAM2 or CAM3 affects other cameras besides itself. The main reason for the interference of centralized power supply is that the power supply ground of camera is not isolated. To solve this problem: Use dual-power devices with isolation of power supply ground; equip low-power devices with power isolators to block the return path 2 low- power devices can also use power isolators to block the return path 2; use isolated power supplies for each channel, or power the device separately, which are the two recommended methods.

Connector Waterproof Protection
HDCVI cameras need to be well waterproofed and protected. After installation, wrap the BNC connector and power connector tightly with insulated or waterproofed tape to prevent water and external electromotive forces. When metal casing device is installed on metal surfaces such as elevators and buses, the metal casing should not be in contact with the installation surface to prevent water and external electromotive forces.

Maintenance

In order to maintain the image quality and proper functioning of the device, please read the following maintenance instructions carefully and hold rigid adherence.
Disassembly and Desiccant Replacement

• Carefully follow the instructions in the manual when performing any disassembly operation about the device; otherwise, it might cause water leakage or poor image quality due to unprofessional disassemble.
• Please contact after-sale service for desiccant replacement if there is condensed fog found on the lens after unpacking or when the desiccant turns green. (Not all models are included with the desiccant).

Maintaining Lens and Lens Protector

• The lens and lens protector are covered with antireflection coating, which could be contaminated or damaged and result in lens scratches or haze images when being touched with dust, grease, fingerprints and other similar substances.
• Do not touch the image sensor (CCD or CMOS) directly. Dust and dirt could be removed with air blower, or you can wipe the lens gently with soft cloth that moistened with alcohol.

Maintaining Device Body

• Device body can be cleaned with soft dry cloth, which can also be used to remove stubborn stains when moistened with mild detergent.
• To avoid possible damage on device body coating which could cause performance decrease, do not use volatile solvent such as alcohol, benzene, diluent and so on to clean the device body, nor can strong, abrasive detergent be used.

   • 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
