How do you fix the damage
3. Distortion or geometric distortion of the image: check whether the optical lens is abnormal; Whether the output impedance switch of the monitor is set at the 75 o terminal; Check whether the use of video connected cable impedance is 75 euro.
4. Like a white fog: check whether there is water mist inside the body. Check whether the lens sleeve is pressed against the glass; Check whether the body has a lens sleeve; Check whether there is water mist in the CCD of the board machine; Check whether the electronic shutter of the machine is open (turn it off if you open it).
2. Bad image quality should be checked: whether the lens has fingerprints or is too dirty; Whether the aperture is adjusted; Video cable contact; Whether there is a problem with the electronic shutter or white balance setting; Whether the transmission distance is too far; Whether the voltage is normal; Whether there is a disturbance source nearby; Whether the CCD of the plate machine is uneven; Check whether the lens is a c-type interface or a CS interface, and if the c-type interface must add a loop, if the CS type interface is removed.
1. If the monitoring camera has no image. Need to check whether the power supply is connected and whether the power supply voltage meets the requirements (power source error: DC12V + 10% AC24V + 5%); Check whether the BNC or video cables are in good contact; See if the lens aperture is open; Check whether the automatic aperture lens control line of video or dc drive is short-circuited; Check whether the video leakage caused the CCD board to burn out.
