TROUBLESHOOTING
a. No picture after applying power – (i) check all plugs and cables are connected to the
proper connectors: (ii) ensure your power supply is providing the correct voltage and
enough 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 the 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. If possible, increase the distance between the camera and
any fluorescent lamps in the vicinity.
d. The picture appears smeared – (i) The power supply voltage level may be unstable.
Try another power supply. (ii) Ensure the cables are correctly connected and of the
right impedance.
e. Other interference may require the use of a SecurityTronix ground loop isolation filter.
f. Power is on but the controller does not work – (i) Check to make sure the DIP switches
are all set correctly for address, baud rate and protocol. (ii) Check that the RS485 wires
at the camera and controller have correct polarities. (iii) Check the integrity and
continuity of the Unshielded Twisted Pair (UTP) cable.
