5. TROUBLESHOOTING
a. No picture after applying power – (i) check all connectors and cables are securely
connected to the video source, monitor, transmitter and receiver; (ii) ensure all power
supplies are providing the correct voltage and current.
b. No image or poor image quality – determine if the optical signal loss is greater than 18
dB.
c. The picture has ripples – (i) check to see if the camera's power supply is experiencing
AC ripple, if so a filter may be required; (ii) determine if the monitor is faulty; (iii)
determine if other peripheral equipment is causing ripple and if so make the necessary
adjustments.
d. The picture background continuously changes color – a fluorescent lamp's magnetic
field may cause color roll, therefore, reduce the number of fluorescent lamps or
increase the distance between the camera and the lamps.
e. The picture appears smeared – (i) the camera's power supply voltage level may be
unstable, therefore, try another power supply; (ii) ensure the camera and/or monitor
cables are correctly connected and/or the cables are of the correct impedance.
f.
Other interference may require a Fibertronix ground loop isolation filter.
g. Data communications are not working – (i) ensure all cables and connectors are
secured and (ii) all terminal block connections are consistent as specified in the wiring
diagram for the transmitter and receiver and the PTZ camera.
