What affects the price
— System type & brand. A wireless DIY-grade kit costs a fraction of a professional wired alarm-and-CCTV combination.
— Number of cameras & sensors. Each additional camera or sensor adds hardware and installation time.
— Wired vs wireless. Cabling through walls and roof spaces adds labour but improves reliability.
— Home size & construction. Two-storey homes and solid-brick walls make cable runs slower and dearer.
— Monitoring. Back-to-base monitoring adds an ongoing monthly fee on top of the installed price.
Tips before you post
— Cabling that runs alongside mains wiring must be done by a licenced or registered cabler — ask before booking.
— Check the ongoing costs: monitoring plans and cloud video storage subscriptions often outgrow the hardware price.
— Aim cameras at your own entries and driveway — filming neighbouring properties can breach privacy rules.
