Expert CCTV Troubleshooting and fault finding
For faults that come and go: cameras that drop out at night, recordings with gaps or viewing that works one day and not the next. We trace the cause methodically.
- Methodical testing
- Network checks
- Clear findings
When the fault is not obvious
Intermittent problems need a proper investigation
Some CCTV faults are easy to see. Others only appear at night, in wet weather, when the heating comes on or when the internet is busy. These are the faults that get “fixed” again and again without ever going away.
We test the system one layer at a time: cameras, cabling, power, network switches, the recorder and the internet connection. We read the recorder logs, check the network for conflicts and look at what changed around the time the problem started. Then we explain what we found in plain English and how to fix it.
- Recorder logs and event history reviewed
- Cables and connectors tested end to end
- Network, IP address and bandwidth checks
- Plain-English findings and next steps
What we investigate
Where intermittent CCTV faults hide
Weather-related dropouts
Moisture in joints and housings that only shows up when it rains.
Night-time failures
Infrared loads that overstretch a power supply after dark.
Network conflicts
Duplicate IP addresses, overloaded switches or router changes.
Recording gaps
Schedules, motion settings and failing drives that leave holes in footage.
Wireless interference
Busy Wi-Fi channels and weak signal on wireless cameras.
Remote access faults
Viewing that fails away from home because of router or cloud settings.

What affects the cost
We agree the scope with you before we start. The cost depends on:
- How many cameras and devices are involved
- Whether the fault can be reproduced on the day
- Access to cameras, cable runs and the network cabinet
- Any repair work you choose to go ahead with
