Home CCTV Systems UK 2026: Wired or Wireless?

For any UK home where you can run cable, wired PoE (Power over Ethernet) is the sensible default, because one network cable carries both power and video and doesn't depend on Wi-Fi signal getting through your walls. Wireless or battery cameras make more sense in a rented flat, or anywhere you have no practical cable route. Even then, "wireless" only describes the video link, so each camera still needs a power source. Your walls, the nearest power point and whether you can reach the loft should decide this, not the spec sheet.

Which home CCTV system suits your property: wired or wireless?

Wired PoE is the better default for most owned homes. Wireless or battery cameras earn their place mainly where drilling isn't possible, such as a rented flat.

This is general installer guidance by property type, not test data:

• Semi with cavity walls: wired PoE if the loft or gable end is reachable for cable runs, with wireless for one awkward side.
• Victorian terrace with thick masonry: wired by default, because Wi-Fi rarely reaches the rear.
• New-build: check the Wi-Fi signal at the exact camera position before buying, then lean wired.
• Rented flat: wireless or battery cameras with no drilling, subject to landlord consent.

"Wireless" describes only the video link. The camera still needs power, from either a mains adapter or a rechargeable battery.

The wired route pairs an NVR with PoE cabling, so a single cable to each camera carries both power and video. If you aren't running that cable yourself, use an independent installer accredited by NSI or SSAIB.

Why does Wi-Fi fall over in brick, cavity insulation and new-build walls?

Dense walls absorb and reflect Wi-Fi, so the signal at the spot where you want a camera may be weaker than it is indoors.

Solid masonry, foil-backed insulation boards in cavity walls and the dense plasterboard systems common in new builds all weaken the signal. Foil is the worst offender because it reflects radio waves rather than letting them through. A camera on an outside wall often has two or three of these layers between it and the router.

Test before you buy

Check the signal on a phone at the exact spot where the bracket will go, not in the room next to it. Then repeat it at night and in the evening, when the household is streaming and neighbouring networks are busiest.

If the signal is weak or erratic, treat that as a reason to go wired. An extender only repeats a signal that must first reach it, and it adds another point of failure.

What a dropout costs

A wireless camera that loses its connection can miss the very event you installed it for. A wired PoE camera sends video down the cable to the NVR, which records whether or not the router is working. The technical comparison is in our Best NVR CCTV Systems: PoE vs WiFi page.

Mains, battery or solar: where can the camera actually be powered?

Power follows location: battery suits sheltered, quiet spots, solar needs a bright aspect, and mains or PoE suits anywhere you can run cable.

Battery

Battery cameras work best under a porch or in a side passage where little happens. A busy driveway triggers recording constantly and drains the cell quickly. Battery life varies by model and settings, so check the datasheet for your camera rather than trusting a headline claim. Mount it where you can reach it, because it will need recharging. For a wider look at costs and returns before you choose between battery, solar and wired kit, see our business CCTV systems UK cost and ROI guide.

Solar

A solar panel needs light on its face. A north-facing eave or a shaded alley starves it, and under UK cloud with short winter days the shortfall shows up exactly when evenings are longest. If you're weighing a panel-fed camera for a dim spot, work through the CCTV Checklist for Dark Evenings page first.

Mains or PoE

PoE carries power and data on a single network cable, so the camera needs no nearby socket. It is the tidiest option for fixed positions you don't want to revisit.

If a camera needs a new mains spur, have your own qualified electrician fit it to BS 7671, with the cable sized by them. We sell the equipment and don't carry out installations. Where you want a professional installer, the NSI lists approved companies working to its NCP 104 code of practice.

How do you run Ethernet through loft voids, soffits and cavity walls?

Take the cable from the camera into the loft through a single drilled entry point near the eaves, then run it across the loft void to the NVR or PoE switch.

The entry point depends on the house:

• Semi-detached: work from the loft side, using the party-wall end of the roof space to keep the run short and the drill hole tidy.
• Terrace: go in from the rear elevation, since there is no side access and the front is usually the wrong place for a visible cable.

Through a cavity wall, drill once and sleeve the hole so the cable doesn't rub on masonry. Add a drip loop outside and seal the entry. Keep the low-voltage Ethernet apart from mains cabling in the loft, and ask your electrician to apply the BS 7671 separation rules.

Because the customer's own electrician or installer does the fitting, follow each camera's datasheet or installation guide for cable type, maximum run length and connector sealing. We sell the equipment and don't install it.

When the route is blocked

If a soffit is boxed in, the loft is boarded solid or the wall is inaccessible, use a wireless bridge or a single wireless camera. Don't push every camera onto one shared Wi-Fi network. Keep the wired cameras and recorder on their own, and give any wireless link a dedicated connection.

Rented flats

In a rented flat, check the tenancy agreement and get the landlord's written consent before drilling anything. If drilling isn't allowed, a single wireless camera covering your own entrance is the lower-impact option.

For professional fitting, choose an independent installer. The NSI home CCTV page explains that NSI-approved companies must work to NCP 104 when they design, install, commission and maintain systems.

What does each route cost, and which should you buy?

Buy a wired PoE system with a local recorder if you can run cable. It largely avoids subscriptions, which is where wireless and cloud routes keep charging you.

Whichever route you take, the cost breaks down the same way:

• Cameras, one per area you need covered
• A recorder plus hard drive (wired), or microSD cards or a cloud plan (wireless)
• Cable, sized to your longest run
• A PoE switch, only if the recorder lacks enough PoE ports
• Fitting labour, which is your own time or an independent installer's, because Clear Security sells equipment and does not fit it

Cloud storage is the item that recurs monthly. Local recording to a recorder or SD card does not. For actual figures, use the installation cost guide for fitting and the shop's live product pages for equipment. This page gives no totals because they date quickly.

Shop prices include VAT. Delivery is £5.99 per order, or free at £100 or more. Orders for items in stock placed before 4pm, Monday to Friday, are dispatched the same working day; orders placed after 4pm or at the weekend are dispatched the next working day. On a distance sale you have 14 days to change your mind and 30 days to reject faulty goods.

A camera that overlooks a neighbour's property or the street can take you outside the domestic exemption and bring UK GDPR duties with it, so read the GDPR guide first. If you hire a fitter, choose an NSI or SSAIB-registered firm; NSI-approved companies work to NCP 104.

Which route suits whom:

• Wired PoE with a recorder: most houses, and small shops or offices where cable can reach.
• Single SD-card camera: one door, or a rental where drilling is off the table.
• Cloud plan: only if you accept the monthly charge for off-site clips.

You can browse the range or ask for a suggested system sized to your property.
