1. Infrared HD IP camera works normally during the day, but there is no signal at night.
Cause: The power supply is insufficient. Since the infrared light is turned on at night, the infrared light will consume a certain amount of current. If the power quality is not good, the power supply will be insufficient, resulting in the HD network camera not starting properly.
Solution: Replace the current power supply and replace it with a good quality power supply.
2. HD IP camera frequently lose network of uncertainty.
Cause 1: The camera uses a centralized power supply. HD network cameras require higher power adapters than analog cameras. It requires relatively stable voltage and current, and voltage and current are unstable due to centralized power supply. Unable to restart or start HD webcam.
Solution: Replace with a separate power supply and use a better power supply
Cause 2: The quality of the network cable is poor. HD video requires a relatively high network transmission rate. Therefore, network packet loss will be very obvious. For example, the cable often drops and the image is not displayed at all.
Solution: use GB copper cable
Cause 3: The distance between the HD network camera and the switch, between the switch and the switch, and between the switch and the IP camera or HD NVR exceeds 100 meters.
Solution: You can add a switch with relay function up to 100 meters in the middle or use fiber optic transmission.
Cause 4: The IP address conflict between the HD network camera and other network devices in the LAN.
Solution: Modify the IP address of the security network camera or other network device to ensure that the IP address does not conflict.
Cause 5: The bandwidth of the network switch is insufficient.
Solution: If the number of HD network cameras is large, it is recommended to use H3C full Gigabit switches. Note that not only does the central switch use gigabit, but if the front-end switch has more than seven cameras, Gigabit switches are also recommended.
