CCTV Cabling Installation in Leicester
The cabling is the backbone of any CCTV system. We run Cat5e or Cat6 cable through lofts, wall cavities, and external conduit - properly clipped, protected, and tested. Hardwired PoE cabling delivers power and data on a single cable with no signal dropouts, no battery changes, and no reliance on your Wi-Fi network. The cable outlasts every other component in the system.

What you get
Cat5e/Cat6 cable runs
Structured cabling from NVR to every camera position. Each run is continuous with no joins, properly terminated, and tested for connectivity and PoE power delivery.
Internal routing
Cable routed through loft spaces, wall cavities, and under floors where possible. Clipped neatly, fire-rated where required, and hidden from view.
External cable protection
Where cable must run externally, it is protected in UV-rated conduit or trunking. Cable entry points are sealed against water ingress with proper glands and sealant.
Termination and testing
Every cable terminated with quality RJ45 connectors or patch panel ports. Each run tested for continuity, correct wiring order, and PoE negotiation before cameras are connected.
How it works
Route planning
Cable paths are mapped during the site survey. We identify loft access points, cavity drops, conduit runs, and any obstacles before installation day. No routes are improvised.
Cable installation
Cables are pulled through planned routes, clipped at regular intervals, protected externally, and brought to each camera position with enough service loop for termination.
Terminate and test
Every cable is terminated, labelled, and tested. We verify continuity, wiring order, and PoE power delivery on each run before any camera is connected.
Why hardwired cabling beats wireless every time
Wireless CCTV cameras rely on your home Wi-Fi to transmit video, and Wi-Fi is not designed for continuous high-bandwidth video streaming. A single 4MP camera streaming 24/7 uses more sustained bandwidth than most household devices. Add four cameras and your Wi-Fi network is under constant load - competing with phones, laptops, smart TVs, and everything else in the house. The result is dropped frames, buffering on playback, failed recordings during peak usage, and cameras that intermittently disconnect and need power cycling. We see this regularly on properties across Leicester where homeowners bought wireless cameras expecting simplicity and ended up with unreliable footage.
Hardwired PoE cabling eliminates every one of these problems. Each camera has a dedicated Cat5e or Cat6 cable that carries both power and data. There is no competition for bandwidth, no signal degradation through walls, no interference from neighbouring Wi-Fi networks, and no batteries to change. The camera receives consistent power and maintains a permanent wired connection to the recorder. This is why every professional CCTV installation uses wired cabling, and why we do not install wireless camera systems. Our PoE vs Wi-Fi comparison covers the technical differences in detail if you want the full picture.
Cable routing on Leicester properties
Leicester has a wide mix of property types, and each presents different cabling challenges. Victorian terraces in Clarendon Park and Stoneygate have solid brick walls, narrow loft spaces shared across party walls, and limited cavity options. We typically route through the loft where accessible, drop through internal walls to first-floor level, and use external conduit in matching colours for the final run to the camera. On semi-detached and detached properties in Oadby, Wigston, and Glenfield, loft access is usually better and cavity walls provide more routing options. New-build estates around Hamilton and Thorpe Astley are easier again - cavities are standard, loft spaces are open, and first-fix cabling can sometimes be run before the house is decorated.
Commercial properties bring different challenges. Warehouses and industrial units around Meridian Business Park or Troon Way often need long cable runs - Cat5e is rated to 100 metres, which covers most situations, but larger sites may need intermediate switches or fibre links. Retail units on Belgrave Road and Narborough Road frequently have suspended ceilings that make routing straightforward, but listed buildings in the city centre may restrict where cable can be surface-mounted. All of this is assessed during the property survey so there are no surprises on installation day.
External cable runs need particular care. Any cable exposed to weather is protected in UV-resistant conduit colour-matched to the wall where possible. Cable entry points into the building are sealed with proper glands - not silicone squeezed around a hole. We see a lot of existing installations where cable has been run along walls with no protection, clipped with inappropriate fixings, or entered the building through unsealed holes. Within two to three years, UV degradation cracks the cable sheath, water tracks along the cable into the building, and the connection starts failing. Doing it properly at installation costs almost nothing extra and prevents expensive remediation later.
Cat5e vs Cat6 - which cable and when
For the majority of residential CCTV installations in Leicester, Cat5e is the right choice. It supports Gigabit Ethernet up to 100 metres, carries PoE power comfortably, and handles 4K video from modern IP cameras without any bottleneck. Cat5e is slightly thinner and more flexible than Cat6, which makes it easier to route through tight loft spaces and around corners in older properties. Every residential system we install uses Cat5e unless there is a specific reason to upgrade.
Cat6 comes into play on larger commercial installations where future-proofing matters or where the same cabling infrastructure may carry other network traffic alongside CCTV. Cat6 supports 10 Gigabit Ethernet over shorter distances and has better resistance to crosstalk, which is relevant when multiple cables are bundled together in trunking or conduit on commercial runs. For a 16-camera warehouse system or a multi-floor office installation, Cat6 with patch panels at both ends is the right specification. We advise on the correct cable grade during the initial site assessment based on the system size and property type. Our cable and network specifications covers network requirements for different camera resolutions if you want to understand the technical side.
Patch panels, labelling, and larger installations
On residential systems with four to six cameras, cables typically terminate directly into the NVR's built-in PoE ports with RJ45 connectors. This is clean, simple, and reliable. On larger commercial installations - eight cameras and above - we install a patch panel at the recorder end. Every cable is punched down to a numbered port, labelled with its camera location, and patched to the NVR or PoE switch with short patch leads. This makes future maintenance, troubleshooting, and expansion straightforward. If a camera needs replacing or a cable develops a fault, you can identify and isolate it in seconds rather than tracing unlabelled cables behind a rack.
Labelling sounds minor but it matters enormously when someone needs to work on the system two years later. Every cable we install is labelled at both ends - at the camera and at the recorder or patch panel. We use printed labels, not marker pen on white cable that fades within months. On commercial installations, we also provide a simple cable schedule documenting which port corresponds to which camera location. This level of documentation is part of what separates a professional installation from a DIY job, and it feeds directly into the commissioning and handover where every cable and connection is verified.
Cable testing and quality assurance
Every cable run is tested before a camera is connected to it. We verify continuity on all eight conductors, confirm correct T568B wiring order, and test PoE negotiation to ensure the cable can deliver power reliably over its full length. On commercial installations, we also test for crosstalk and verify cable length to confirm no run exceeds the 100-metre Ethernet limit. A cable that tests fine at the point of installation but was nicked during pulling, kinked around a tight bend, or crushed under a loft board will fail under load - testing catches these problems before they cause intermittent faults that are far harder to diagnose later.
We also leave a service loop at every camera position - approximately 30cm of spare cable coiled neatly behind the camera mount. This allows the camera to be repositioned slightly, the connector to be re-terminated if needed, or a different camera model to be fitted in future without pulling new cable. It is a small detail that saves significant time and cost if any changes are needed down the line. The cabling infrastructure should last 15-20 years or more - well beyond the lifespan of the cameras and recorder it connects. Getting it right at installation means the most expensive part of the job never needs doing again.
Cabling is one stage of a complete CCTV installation. For an overview of the full process - from site survey through infrastructure to final commissioning and handover - see our complete CCTV service overview page.
Pricing
Cabling cost depends on the number of runs, route difficulty, and whether internal or external routing is required. We provide a fixed price after the site survey - no hourly rates and no surprises on installation day.

Frequently asked questions
- Can you run CCTV cable through my loft?
- In most cases, yes. Loft routing is the preferred method for residential installations as it keeps cable completely hidden. We check loft access and headroom during the site survey to confirm it is feasible before committing to a route.
- Will you need to drill through external walls?
- Usually one or two small holes per camera for the cable to exit the building. These are drilled at a downward angle to prevent water ingress, sealed with appropriate glands, and positioned as discreetly as possible. We discuss exact locations during the survey.
- How long does the cabling last?
- Cat5e and Cat6 cable installed internally has a lifespan of 20-25 years. External cable in conduit lasts 15-20 years. The cabling infrastructure will outlast multiple generations of cameras and recorders - it is the most permanent part of the system.
- Can you add cable runs to an existing system?
- Yes. If you want to add cameras to an existing installation, we can run additional cables to new positions. We check whether the existing recorder and PoE switch have spare capacity during an initial assessment.
- Why not just use Wi-Fi cameras instead of running cable?
- Wi-Fi cameras rely on your home network and suffer from signal dropouts, interference, and bandwidth competition. Wired PoE cameras deliver power and data on a single cable with zero reliance on Wi-Fi. Our PoE vs Wi-Fi guide covers the full comparison.
- Do you install conduit on the outside of the building?
- Where external cable runs are necessary, yes. We use UV-rated conduit colour-matched to the wall wherever possible. External routing is planned during the site survey so it follows the neatest path and avoids visible runs across prominent elevations.
