Vandal-Proof Cameras for Reachable Positions

Vandal-proof is not explosion-proof

These two terms get swapped constantly in specifications, and swapping them sends the project to the wrong supplier. Vandal-proof — also written anti-vandal or vandal-resistant — means the device resists being struck, levered or pulled off its mount. That is what a lift lobby, a car park soffit, a stairwell or a street-facing ground-floor position needs.

Explosion-proof means the enclosure contains an internal ignition and cannot ignite a flammable atmosphere. It is an ATEX-class product for refineries, chemical plant, mines and other hazardous areas. It is a different product with different certification, and it is not what you want when the risk is somebody hitting the camera with a broom handle.

If your specification says explosion-proof but the requirement is really "cannot be smashed", correct it before you go to tender. Specifying the wrong word attracts quotes for equipment that does not fit the site — and the price difference is large.

Positions that need it

• Lift lobbies and lift cars — the camera is within reach of everybody who uses the building.
• Car park soffits and columns — reachable from a vehicle roof or a trolley.
• Stairwells and service corridors — unsupervised and rarely occupied.
• Ground-floor facades and street-facing positions — reachable from the pavement.
• Retail stock rooms and till areas — staff and public both have access.
• Construction and vacant sites — the highest-risk case, where the camera itself is the target.

What to look for in the housing

The housing is doing the work, so judge it on its own terms. A cast metal base resists levering where a plastic one cracks. Recessed or captive fasteners remove the screwdriver opportunity. A dome that is difficult to rotate holds its aim after an impact. And for an outdoor soffit, the seal and cable entry decide whether water reaches the connector in year two.

The camera inside is our standard 5 MP dome module, so image quality and night behaviour are unchanged. Selecting a housing does not mean accepting a worse picture.

Writing it into a specification

Be specific about the threat rather than the product. "Camera in a vandal-resistant housing, cast base, captive fixings, suitable for a car park soffit" tells a supplier what to quote. "Explosion-proof camera" tells them to quote a hazardous-area enclosure that neither the site nor the budget needs.

For each position, note three things: how high it is, what somebody could reach it with, and whether it is indoors or exposed. Those three facts determine the housing more reliably than any catalogue category.

The housing is the product here

For a reachable position, the camera module is the easy half. What decides whether the install survives is the housing: cast base, captive fixings, and a dome that holds its aim after an impact.
