In order to save the loss, please read the following item carefully.
The product has a good reliability on original design. But still need avoid human damage.
7. Do not repair the device on your own.
8. Please arrange thunder protect device when install the product outdoor.
Fault analysis
You can consider to pick the below solutions to settle down the issues you have when you install the devices.
1. POWER LED can’t work normally:
Please check whether the power connection is well.
2.No video signals
Please check the video LED of receiver
3. Interfere with snow screen
This is normally caused by attenuation of fiber or long wire between camera and Fiber Transmitter. (PS: please use high quality wire cable and connector.) |
