TROUBLESHOOTING
a. No picture after applying power – (i) check all plugs and cables are securely
connected to the proper connectors; (ii) ensure your power supply is providing the
correct voltage and current.
b. The picture has ripples – (i) check to see if the 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.
c. 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.
d. The picture appears smeared – (i) the power supply voltage level may be unstable,
therefore, try another power supply; (ii) ensure the cables are correctly connected
and/or the cables are of the correct impedance.
e. Other interference may require a Securitytronix ground loop isolation filter.
f. Power is on, but the controller does not work – (i) check to make sure the DIP
switches for address and communications baud rate are properly set, (ii) check to
ensure the RS485 connections at the camera and the PTZ Controller have the same
polarity, (iii) check the integrity and continuity of the unshielded twisted pair (UTP)
control cable.
