CCTV Installation in Hertfordshire

Watford is where we are based. Our workshop and stores sit on Mowat Industrial Estate in WD24, ten minutes from the town centre, which means a Watford survey usually happens within a couple of days of your call rather than a couple of weeks.

The property mix here shapes the camera design. The Cassiobury estate is Edwardian and 1930s detached houses with deep front gardens, gated side returns and coach houses at the back of the plot. Nascot Wood and the roads off Hempstead Road are large family homes where the risk is rarely the front door and far more often the driveway, the side passage and the rear garden gate. Around Cassiobury Park and the town centre, terraces and conversions have shared alleyways behind them, and that alley is where bicycles, tools and deliveries disappear.

A typical Watford installation is four to six 4K cameras: one on the front elevation covering the drive and the approach, one down the side return, two covering the rear garden and the outbuilding or garden office, and one on the rear gate. Where the house has been split into flats or rented out, we design around shared access instead, with a recorder that the landlord can see remotely and a resident who can see only the entrance camera. Signage and a written retention policy are part of the job, not an optional extra, because a camera pointing across a shared driveway is a data protection issue as much as a security one.

Watford also has a lot of new-build apartments near the Junction and the hospital. In those we tend to be working with a managing agent, on communal entrances, bin stores and parking courts, and the camera has to be specified for the lighting that is actually there rather than the lighting the architect drew.

St Albans is the most sensitive place we work in Hertfordshire, because so much of it is conservation area and a good deal of it is listed. Cameras still work there. They just have to be chosen and fixed with more care than usual.

The city centre streets around the Cathedral, Fishpool Street and Romeland are Georgian and Victorian, with painted timber, lime render and brick that you cannot screw a camera bracket into and walk away. Further out, Marshalswick, Clarence Park and Batchwood are Edwardian and 1930s family houses with long rear gardens, detached garages and, quite often, a home office at the bottom of the garden that holds more value than the contents of the house.

In the conservation area we work to two rules: nothing gets fixed to historic fabric if it can be fixed to a modern soffit, gutter bracket or boundary post instead, and every fixing is reversible with the original surface made good. Where the building is listed we coordinate the listed building consent application ourselves and specify small dark grey or black domes that read as a light fitting from the street. On the long gardens in St Albans, one camera at the rear of the house rarely reaches the far fence with enough pixel density to identify anyone, so we either add a second camera on the garage or run a single run of armoured Cat6 to a camera at the boundary. Distance is the thing people underestimate, and it is the reason a two-camera quote sometimes becomes a three-camera one after the survey.

On-street parking is tight across much of AL1 and AL3, so a camera covering the bay in front of the house earns its place. We also fit a lot of door entry and intercom work in the city centre conversions, and where that is the case the entrance camera and the intercom camera should be the same device rather than two things competing for the same view.

WD3 is where plot size starts to dictate the whole design. Houses along the Chess valley, the canal-side properties and the wooded lanes around Chorleywood and Loudwater sit behind long drives, hedges and gates, and a camera on the front wall of the house is looking at very little.

The practical answer is to move the cameras out to the boundary and the gate rather than clustering them on the building. That means a run of external-grade Cat6 or, where the distance exceeds the 100-metre limit of power-over-ethernet, a fibre link back to the plant room. We do this regularly in Chorleywood and it is the single most common correction we make to a system somebody else installed: four cameras all pointing at the same gravel.

Rickmansworth also has a lot of outbuildings in real use — garden studios, annexes, a workshop, sometimes a stable block. Those need their own network segment and their own camera, and the recorder has to sit somewhere dry and secure rather than in a shed. Where a property has electric gates we integrate the intercom with the camera so that answering the gate also brings up the view of whoever is standing at it, and the same camera records the vehicle behind them.

Wildlife is a genuine consideration on the wooded edges. Deer, foxes and cats will trigger a basic motion camera all night long, which is why we specify analytics that distinguish a person or a vehicle from everything else before an alert is sent to your phone.

Harpenden work is usually either a substantial detached house on a generous plot, or a barn conversion where the building fabric makes cable routing the whole project.

On the large detached houses around East Common, Rothamsted and the roads off Luton Road, the camera plan is straightforward but the coverage is not: driveways that take three cars abreast, side gates, a rear garden that runs to a hedge, and often a summerhouse or pool building at the far end. We survey in the evening as well as the day, because the deciding factor on these plots is what the lighting does after dark. A camera facing a floodlight is useless, and a camera facing an unlit corner is worse.

Barn conversions are the opposite problem. Exposed timber frames, vaulted ceilings and original boarding leave nowhere obvious to run a cable, and nobody wants trunking screwed to oak. We route through existing service voids and the roof space where we can, use a discreet wireless bridge from the main building to an outbuilding where we cannot, and keep the recorder in the plant room or utility rather than a bedroom cupboard. In green belt parts of AL5, external cameras on outbuildings may need consent, and we will tell you at survey stage rather than after the invoice.

These are the biggest plots we work on in Hertfordshire, and often the most gated. When a property has two entrances, a long boundary and a shared access road, the camera system stops being about the front door and becomes a perimeter design.

In Radlett and the Aldenham side of Bushey we routinely design eight to twelve camera systems: entrance gates, the drive, the parking court, both side boundaries, the rear terrace, the pool or tennis court, and the outbuildings. Where the plot is gated we combine the gate intercom, the access control and the camera so the household sees and speaks to a visitor in one action, and the recording of that visit is searchable later by date and time rather than scrubbed through.

Retention matters more on these sites. Thirty days is the residential default, but properties with staff, contractors and regular deliveries often ask for ninety, and that changes the recorder and the drive size rather than the camera count. We size storage properly at quote stage instead of adding drives afterwards. The recorder itself belongs in the rack or plant room with the rest of the network, on a UPS, on its own VLAN, and not on the kitchen Wi-Fi.

EN6 is a mix of interwar houses on good plots, newer executive developments, and lanes where the gardens back onto woodland. It is also the Hertfordshire corner closest to us by road, straight down the A1(M) or across the M25.

On the new-build estates around Potters Bar and Cuffley we are usually brought in either before plasterboard or immediately after handover. Before first fix is much better: a camera position is a Cat6 cable to a specific point with a 100mm back box, decided at the same time as the alarm and the network, and it costs a fraction of what chasing the same cable into a finished hallway costs later. Where a developer has already installed coax and a builder-grade recorder, our honest advice is often to replace rather than extend, because the cabling cannot carry 4K cameras and the recorder cannot handle analytics.

On the older houses and the woodland-edge lanes, the pattern is more familiar: front drive, side access, rear garden, and a gate onto the woods that needs watching precisely because it is the quiet way in. These are also properties where the Wi-Fi rarely reaches the cameras, so we hardwire and treat the CCTV network as infrastructure rather than something bolted onto the home router.
