New CCTV equipment not compatible with existing analogue cabling: what causes it and how it is fixed in Bean
Understand why a CCTV upgrade is not working with existing cables. This page covers the causes worth checking on security fog systems, what you can safely check yourself, and what an engineer does on the visit.
- Fault: new CCTV equipment not compatible with existing analogue cabling
- System in view: security fog system
- Priority: safe to handle as planned work
Symptom
Picture works but at noticeably reduced resolution
Check first
Confirm the recorder's supported camera resolution and format before buying new cameras
Likely cause
Recorder does not support the new camera's resolution or format
The behaviour people describe
The underlying question is simple, understand why a CCTV upgrade is not working with existing cables.
- Picture works but at noticeably reduced resolution
- Mixture of old and new equipment behaves inconsistently
Before you pay anybody
If either of these clears the fault, there is no reason to book a visit at all.
- 1Confirm the recorder's supported camera resolution and format before buying new cameras
- 2Check the age and quality of existing cabling against the new equipment's requirements
Where the fault normally originates
- Recorder does not support the new camera's resolution or format
- Adding a higher-specification camera to an older recorder that caps out at a lower resolution wastes the camera's capability entirely.
- Power supply mismatch
- Newer cameras sometimes have different voltage or current requirements from the equipment they are replacing.
Security fog systems: the components in play
The reason this matters: a security fog system fails in a different order to other kit.
- Fluid cartridge
- Consumable that needs replacing after each discharge.
- Coverage-matched unit sizing
- Ensures the volume of fog suits the size of the protected room.
What the visit involves
Timing-wise: safe to handle as planned work.
- 1Confirm compatibility between recorder, cameras and existing cabling before committing to new hardware
- 2Re-terminate or replace cabling where signal quality is limiting performance
Where a Edwardian semi feels this fault
- Side passage leading to the rear garden, frequently gated but rarely alarmed
- That is the access route that needs to be covered reliably, which is why new CCTV equipment not compatible with existing analogue cabling there is worth fixing rather than living with.
- Perimeter lighting along the side passage and rear boundary
- A long, narrow side approach benefits particularly from lighting that removes the cover an unlit passage provides.
Locally, in Bean
Across the DA2 postcodes, a2 proximity makes opportunist drive-up attempts more common, driveway entrance cameras and gate sensors solve most of it.
What no amount of spending will fix
Fluid cartridges are a recurring cost after every discharge, including accidental ones. Fluid levels and trigger linkage checked at service visits, with cartridges replaced after any discharge.
Stopping it coming back
Check compatibility across the full chain of recorder, camera and cabling before purchasing any replacement equipment.
