Camera Maintenance and Troubleshooting
6.1 Camera Maintenance
1.
If the camera will be idle for a long time, please turn off the power switch and disconnect AC power cord from
outlet.
2.
Use soft cloth or tissue to clean the camera (lens cleaning not recommended).
3.
Use the soft dry cloth to clean the lens. If the camera is very dirty, clean it with diluted neuter detergent. Do not
use any type of solvents, which may damage the surface.
6.2 Troubleshooting
1) No Video Output
a. check whether the camera power supply is connected, make sure the voltage is normal, or whether the power
indicator is on.
b. whether the machine could do self-check upon starting.
c. check whether the bottom of the DIP switch is set to the normal operating mode (see Table 1.2 and Table 1.3).
d. check whether the video output cable is connected correctly, and the video display is normal.
2) No Image Sometimes
Check whether the video output cable is connected correctly, and the video display is normal under the normal
operating mode.
3) Image Dithering When Zoom-in/out
a. check whether the camera’s installation position is solid.
b. check whether there is a shaking machine or object near the camera.
4) Remote Control Cannot Work
a. check whether control address is set to 1 (if the machine is set to factory default settings, remote control address
needs to be set back to 1).
b. check whether the battery is installed in the remote control, and whether the battery power is high enough.
c. check whether the camera is under the normal working/operating mode (see Table 1.2 and Table 1.3).
d. check whether the menu is closed. Camera control through remote control is only available after exiting the
menu. If video is output from LAN, the menu will not show. After 30 sec, camera can be controlled by remote
control.
5) Serial Port Does Not Work
