FAQ

10.1 PoC Power Supply
PoC XVR supports the PoC function.
PoC cameras can be divided into AT cameras and AF cameras. The power consumption of AT camera is less than 12W, and the power consumption of the 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 between the device and PoC XVR or PoC transceiver such as UTC, Balun, optical transceiver, distributor and converter, 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.

10.2 Long Distance Power Supply
In many scenarios, our clients adopt a 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 the 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 the restart of the device and a black screen.
Solution: During construction, when the camera location is far from the power supply, you need to adopt a long-distance separate power supply or purchase –DP dual power supply to use 24V AC power supply.
10.3 Centralized Power Supply
The typical problem of a 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 the 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 the centralized power supply is that the power supply ground of the 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.
10.4 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 a 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 on the device; otherwise, it might cause water leakage or poor image quality due to unprofessional disassembly.
• 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 is covered with the 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 a soft cloth that is moistened with alcohol.

Maintaining Device Body

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