Information on a wide range of housings,
suitable for any application.

SYSTEM WEATHERPROOF CAMERA HOUSING

Normally based on the removable top box design, this type of housing really only differs from a standard camera housing in one respect .... and that's its size.

Whereas a standard housing may only be required to accept a basic camera with a fixed lens, the larger system units are designed in various sizes to accomodate the largest camera and zoom lens combinations.
With this in mind, they are rarely if ever used on simple brackets, but instead fitted onto heavy duty motorised Pan and Tilt Heads, in order to provide maximum flexibility with a zoom lens fitted.

The base of these housings normally provide additional fixing points, so that the overall weight of the load can be adequately balanced over the P/T heads centre of gravity. In addition, some system housings are manufactured in a 'deep base' design, to incorporate the telemetry receiver card, as well as the camera / lens combination and anything else deemed appropriate.

This approach is particularly sensible if cameras are to be temporarily deployed, or used in inhospitable locations, as everything is effectively contained in a single 'plug n play' box.

CORNER MOUNT HOUSINGS

This type of camera enclosure is extremely specialised and in practice, perhaps only a handful of designs are still available worldwide.

If you need to fix a camera into the corner of a room, such as a lift, prison cell or interview room, or maybe a car park, then this type of physical protection may be the only viable option. Although these corner units come in different sizes, they are somewhat restrictive on the type of camera / lens combination that can be accomodated.

As they are generally not used in wide open spaces, it is rare to find any form of heating element incorporated into the design. Because of the location of this type of enclosure, perhaps the most commonly used configuration requires the camera to be fitted with an ultra wide angle lens, for short range use. As such, most corner housings have now been replaced with compact camera designs (such as fixed vandal resistant domes), using a built in PCB based camera with a barrel lens.
