1. Infrared HD
IP Camera Works Normally During the Day,
but there is No Signal at Night.Reason:
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 normally.Solution: Replace the current
power supply and replace it with a good quality power supply.2. HDIP
Cameraare frequently dropped in UncertaintyReason 1: The camera adopts
centralized power supply mode. The requirements of the high-definition
network camera for the power adapter are relatively higher than those of the
analog camera. It requires a relatively stable voltage and current, and the
voltage and current are unstable due to centralized power supply. The HD
network camera can’t be restarted or started.Solution: Change to a separate
power supply and use a better quality power supplyReason 2: The quality of
the network cable is poor. The high-definition video requires relatively high
network transmission rate. Therefore, the network packet loss will be very
obvious. For example, the cable is often dropped, and the image is not
displayed at all.Solution: use the national standard pure copper cableReason
3: The distance between the HD IP Camera and the switch, or between
the switch and the switch, or between the switch and the IP camera or HD NVR
is more than 100 meters.Solution: You can add a switch with relay function in
the middle no more than 100 meters, or use fiber transmission.Reason 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.Reason 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. Please
note that not only the central switch adopts Gigabit, but if the front-end
switch has more than 7 cameras, it is also recommended to use Gigabit
switches.
