6. 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.
