One of the most common problems on a finished shop or home renovation is discovering that the CCTV system was planned after the ceiling, walls and decoration were completed. At that point, running new camera cable inside the building fabric can mean unnecessary cutting, patching and redecorating.
On a real installation, we faced exactly this situation. The practical solution was to create a neat surface cable route using trunking rather than opening finished walls and ceilings.
What is CCTV trunking?
Trunking is a protective surface-mounted cable channel. It lets an installer route Ethernet or CCTV cabling along walls, ceilings and edges while keeping the cable contained and the installation visually organised.
Why it can be useful after renovation
- It can avoid reopening large areas of finished wall or ceiling.
- The route remains accessible if a cable needs inspection or replacement later.
- Good planning around corners, ceiling lines and existing features can make the finished route much less intrusive.
- It is particularly practical for PoE CCTV because one Ethernet cable can carry both network data and power to a compatible camera.
How we approach a retrofit route
- Plan camera positions first. Decide the useful viewing angles before choosing the cable route.
- Find the least visible continuous path. Edges, ceiling lines and existing service routes are usually better than crossing open wall areas.
- Keep the route simple. Unnecessary bends make the installation harder to maintain and usually look worse.
- Choose trunking sized for the actual cable run. Do not force multiple cables into a channel that is too small.
- Label and test every cable before final completion. Confirm PoE link, camera image and network stability before considering the route finished.
Does surface trunking have to look untidy?
No. Poorly planned surface cabling can look temporary, but a carefully aligned route with clean corners and sensible camera positions can be a professional retrofit solution. In our installation, it allowed the CCTV system to be added with far less disturbance to the finished premises while keeping the result acceptable to the customer.
When should you use another method?
Trunking is not automatically the best answer for every building. A concealed route may still be preferable where access already exists, and external or unusual environments can require different containment and cable choices. The key is to choose the route after considering the building, cable length, camera location and future maintenance.
Planning CCTV before renovation
If possible, plan camera positions, NVR location, network equipment and cable routes before walls and ceilings are closed. It is almost always easier to install spare cable or containment during the renovation than to retrofit it afterwards.
Already finished the renovation? It does not necessarily mean you need to damage the new finish. Contact HawkVision Pro with a few photos and the approximate camera positions, and we can help you think through a practical CCTV route and suitable equipment.
