CCTV repair and installation in Mill Hill

Plots in NW7 are bigger, which changes the design. A single camera on the house cannot cover a long drive, a gate and a garden boundary, so we plan a small number of well-framed positions with the cabling to support them.

Outbuildings, garages and garden offices are common here and usually need their own camera and network point. Where an armoured route is needed across a garden we plan it properly rather than surface-clipping cable to a fence.

NW7 around Mill Hill Broadway, The Ridgeway and the roads off Highwood Hill sits on higher, more open ground than much of the borough, with detached houses set well back behind their own gates, sweeping drives and mature hedging. Plots here are noticeably larger than the terraced streets further south, often running to a rear garden with a garage, a garden office or a stable block, and many properties back directly onto open land or Scratchwood. That openness means fewer overlooking neighbours to rely on for a passing witness, so the system itself has to do more of the work across a wider boundary.

A gated Mill Hill drive is usually the first thing worth getting right, and the temptation is to fit one wide camera on the house that tries to cover the gate, the drive and the front door together. At any real distance that produces a picture too wide to identify a face or a number plate, so we split it into a tight, identification-grade view fixed on the gate itself and a second camera further down the drive covering vehicles as they approach the house. Where the gate has an intercom or an automatic opener, we run the camera cable alongside the existing power and control cable in the same duct, which avoids digging the drive twice.

Outbuildings are common on these larger plots — a detached garage, a garden office, sometimes a stable or workshop — and each one needs to be treated as its own small site rather than an afterthought covered by a camera on the main house. That means its own cable run, ideally armoured or ducted where it crosses open lawn, and its own network point so the building can host a camera and, often, other equipment such as a Wi-Fi access point for the garden office. Skimping on this by running surface cable along a fence line is the single most common cause of failure we see on these properties, since strimmers, foxes and simple weathering all take their toll over a season or two.

Boundaries on NW7 plots are frequently unlit beyond the reach of the house's own security lights, so a camera relying on its built-in white light alone will struggle at the tree line thirty or forty metres out. We specify cameras with genuine low-light sensors for boundary positions rather than judging performance from a daytime demo, and where a boundary run is long we plan a mid-point power and data location rather than pushing a single cable run to its limit. The recorder on these jobs usually sits in a plant room or utility area with capacity kept in mind, since five or six cameras covering a large plot at a useful resolution need more storage than a typical terraced house system.
