5. Troubleshooting
5.1. No power
In case of Standard PoE (Power over Ethernet)
Power supply through standard PoE is possible only when the following conditions are met.
1. Standard PoE is supported on the product.
2. The LAN switch supports standard PoE.
Make sure that both the IP camera and the LAN switch support standard PoE (IEEE 802.3af)
In case of DC adaptor
If PoE is not applied, the power and network connection should be made through separate cables.
It is recommended to use DC adaptor supplied by provider for the feeding of the power. In case of
replacing the DC power supply, make sure that the power supply meets with the power
requirement of the IP camera to prevent damage or malfunction.
5.2. Cannot connect to the Video
Check the status of the network connection through PING test.
Try the following on your PC :
-
Start > Run > Cmd > Ping IP address (Ex : Ping 172.16.42.51)
-
If “Reply from ~” message is returned (
①
in the figure below)
, the network connection is in normal
state. Try connection to the video again. If the problem persists, or refer to other trouble shooting notes.
-
If “Request timed out” message is returned. (
②
in the figure below), the network connection or network
setting is not in normal state. Check the network cable and settings.
