Guide to Closed Circuit TV (CCTV)

So would you like to play "Spot the CCTV Camera?". Eagle eyed visitors may recognise the profusion of street furniture, surrounding a single heritage dome camera keeping watch over part  of Londons' prestigious Oxford Street shopping area.

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


Not that many years ago, the idea of a CCTV professional even daring to speak the word ‘covert’ was almost regarded as blasphemous.
Nowadays, adverts in trade magazines, and even publicly available newspapers, delight in describing the latest ‘state of the art’ hidden cameras, for the home and workplace.

Now, you wouldn’t expect Doktor Jon to describe in glowing terms all the different ways in which you can disguise a hidden CCTV camera, but the simple fact is that because a number of these are now so well documented that they are no longer a secret, it isn’t likely to breach any great confidence by describing a couple of them.

Most covert cameras are used indoors, but having said that, effective use of covert units outside, can provide one, if not THE most efficient method for securing a property. External covert housings cannot be described, simply because .... Doktor Jon says so .... so there!

Internal housings generally take the form of commercial clutter such as smoke alarms or PIR movement sensors, both of which are readily available off the shelf, and at a relatively low cost.

In practice, the vast majority of highly efficient covert enclosures are fabricated normally as ‘one offs’ for a specific location, and so any suggestion that these can be described in broader terms, would of course be thoroughly inappropriate. However you will find a lot more information on this subject in the "covert section".


We’ve already touched on some of the more commonly used items, such as internal circulating fans, secondary heat shields and thermostatically controlled heaters; but so far no mention of the two most commonly used ‘bolt on's’. Firstly, screen wipers are widely employed to clear rainwater from the housing window, and much like those fitted to a normal vehicle, they are ‘self parking’ when switched off.
