CCTV systems troubleshooting

When trouble shooting CCTV systems, one needs to follow the basics.

• It is more common now, to blame Load shedding for CCTV equipment not working anymore.
• If your monitor has a no signal error present, then the fault finding is more difficult, the starting point of fault finding is also different.
• When your DVR machine is still displaying its frame work on the monitor and all your cameras are down, it is easy to trouble shoot CCTV systems.
• Such a fault points to the cameras not giving images through, when all CCTV cameras are down it points to the CCTV Cameras power supply source.
• When doing fault finding on CCTV systems;
• Make sure that all equipment is still plugged in and switched on.
• It is common to accidentally move equipment for cleaning purposes and during the moving, electrical connections could become disturbed.
• CCTV systems normally consists of 5x components.
• The dvr machine with its own power supply and image signal cord to the tv set/ monitor.
• The cameras present which are connected with wires back to the CCTV DVR machine, NVR machine.
• The power supplies powering the cameras, which could be one big power supply or individual power supplies for each CCTV camera.
• When a on/ off trouble condition appears (camera coming on and off at times) it is a indication of a poor electrical connection between the camera and the DVR/ NVR or the camera power supply.
