Every installer gets the same request, phrased the same hopeful way: can we do it wireless, so there's no mess? It is a fair question. Cabling means drills, loft crawls and a day of disruption, and the boxes in the shops promise cameras that stick to a wall and just work.
The honest answer is that wireless is a real option with real costs, and the costs are the kind you discover in month six rather than in the showroom.
What wireless really means
Start with a correction: most so-called wireless cameras are only half wireless. The video travels over wifi, but the camera still needs power, so either a cable runs to it anyway or it runs on a battery you will be recharging on a ladder every few weeks, more often in winter. Battery cameras also sleep to survive, waking when motion trips them, which means they record clips rather than a continuous picture and occasionally wake late. And everything depends on your wifi reaching a camera mounted outside on a far wall, which is exactly where home wifi is weakest. When the connection drops, the camera does not complain; it just quietly stops being evidence.
What wired really means
A wired system today usually means PoE, power over Ethernet: one network cable to each camera carries both power and video back to a recorder. No batteries, no wifi dependence, continuous recording to a hard drive in your own house, and cameras that can run better sensors because nobody is rationing a battery. The price is the installation itself, the cable runs, the drilled holes, the day of someone in your loft, which is most of what you are paying an installer for. Done well it is tidy and then invisible for a decade. That is the actual trade: disruption once, against reliability always.
Where each answer is right
Wireless earns its place in real situations: a rented flat where you cannot drill, a listed building where you should not, a detached garage with no ducting, or a single camera to cover one door for a season. If that is you, buy decent kit, accept the battery routine, and treat the footage as a bonus rather than a certainty.
If you own the house, want more than two cameras, and expect the system to hold up as evidence after a break-in, wired is the answer almost every installer will give, and it is not because they enjoy drilling. It is because they have sat with too many customers scrolling through clips that begin two seconds after the moment that mattered.
Putting the question to someone local
The good news is that the awkward part, the cabling, is a solved problem for people who do it weekly. A surveyor will spot the loft route or the trunking line that makes the job cleaner than you feared. There are 335 CCTV system installers listed on this site, and the listings show who works your area and what they concentrate on. Look at installers near you, or put the job out for quotes and ask each firm one blunt question: what would you fit on your own house? The answers converge quickly.
