Why it happens

It is the intuitive way to buy cameras: find the highest corner, fit the widest lens, and the whole yard appears in frame. The commissioning view looks impressive, and in daylight with a person standing mid-frame it seems to work. Budget pressure pushes the same way, because one camera covering everything reads as efficient.

Why it matters

A wide lens spreads its pixels across the whole scene, so detail at the edges and the far end collapses to nothing. You end up with excellent evidence that an event occurred and no ability to say who was involved — which is the one thing an insurer, an investigator or a disciplinary process needs. Sites often discover this only when they first pull footage in anger, months or years after paying for the system.

What we do

We separate overview from identification. One camera can keep the wide context — movement, direction, timing — while identification cameras are placed tight on the handful of points a person must pass through: the gate, the shutter, the yard door, the ramp. We calculate the pixel density across the distance before mounting anything, and we show you sample footage from your own site at your own distances so the expectation is set in advance.

Why it happens

The camera was positioned for the obvious large target. A vehicle is big, slow and brightly lit, so it fills the frame and looks like success. The driver is behind glass, higher or lower than the lens, often in shadow under a visor, and nobody tested the view with somebody actually sitting in a cab.

Why it matters

Vehicles are rarely the question. When a load goes missing, a gate is rammed or a trailer is taken, the useful fact is which person was driving — and a registration plate only tells you about a vehicle, which may be stolen, borrowed or on a legitimate job for somebody else. Without a face, your footage proves a truck was present and leaves every human question open.

What we do

We treat the gate as two shots. A plate camera goes low, square-on and tight to a defined stopping point, set up to cope with movement and headlights. A separate camera is angled into the cab window from the side the driver sits on, at a height that clears the dash and avoids the worst of the windscreen reflection. Both are commissioned with a vehicle and a person actually in place, not from the ground.

Why it happens

Floodlights and cameras are usually installed by different people at different times, each ignoring the other. A light gets added to fix a dark corner and ends up in a camera's field of view. Infrared illuminators sit alongside the lens, so anything close and pale — a wall, a shutter, a post, falling rain — bounces light straight back into it.

Why it matters

A bright source in frame makes the camera expose for the light, so everything around it goes black and anyone walking in front of it becomes an unidentifiable silhouette. Infrared bounce produces an evenly washed-out image that looks like fog. Both failures appear only at night, which is when the footage matters most and when nobody is on site to see that the view has become useless.

What we do

We commission at night as well as in daylight, because a daytime handover tells you very little. Fixtures that glare into a lens get re-aimed or shielded, and cameras are repositioned so light falls across a scene rather than into the glass. Where infrared is bouncing, we move the illumination away from the camera body or switch to external illuminators. We will also tell you plainly where the honest answer is a light in a different place rather than a better camera.

Why it happens

Cameras are installed out of reach so they cannot be tampered with, which also puts them out of reach for cleaning. No one owns the task. The recorder reports every camera as online, so the only dashboard anybody looks at says the system is healthy while the actual images get worse week by week.

Why it matters

Degradation is gradual and invisible without a before-and-after, so staff adjust to a worse picture without registering it. Dust and diesel film soften detail, a web across the lens reflects infrared and whites out the night view entirely, and a failed housing seal lets condensation in permanently. A camera that was adequate for identification at install can slip below useful within a year, and you only find out on the day you need it.

What we do

We put the cameras on a scheduled service: housings and lens covers cleaned, seals and glands checked, mounts retightened, aim verified against the commissioning reference images, and night views reviewed on site. You get a report naming each camera, what was done, and anything that has drifted or is failing. If you are inheriting a system of unknown age, that same inspection is the sensible first step before deciding what to replace.
