And do you know why that is; well it’s very simple really.

The main reason is total piggin’ ignorance! ... just as well I went for a somewhat diplomatic way of describing it :-))

Most end users haven’t really got a clue where to locate a camera, and many of the installers appear to be little better informed.

 

So how exactly do you decide where best to place a camera, and perhaps more importantly, where not!!

 

Just follow Doktor Jon through the basic concept, which is referred to as the "Cone of Containment", and you’ll be amazed at how much more effective CCTV cameras can be, when they're applied more thoughtfully.

 

Be warned though, once you’ve grasped this most simple of ideas, you’ll run the risk of acute DJ syndrome, manifesting as a uncontrollable reflex rage reaction, to the sight of an inappropriately installed CCTV camera.

 

So what exactly is the ‘Cone of Containment’?; well, first things first, whatever you intend to use a CCTV camera for, it’s vitally important to understand and define it’s key objectives. That may be as simple as stating that it must provide evidential quality 'identification level' images of individuals walking along a corridor, entering a shop doorway, or resolving a vehicle registration plate.

 

Whatever the objectives, try and task the camera with one specific function, and concentrate on that; if you ask a camera to do too many things, chances are it won’t be much use for any of them.

So on the basis that you know exactly why the camera is being installed, the next stage is to identify where to place it most effectively.

Doktor Jon explains about the 'Cone of Containment'


Before you can decide on the most appropriate lens for any given application, you first need to decide where to place the camera to best effect.

 

Now you’d think that this part of the exercise would be a piece of .... cake, but in point of fact, as Doktor Jon has travelled to the four corners of his office and beyond, the inescapable fact is that well over 90% of all CCTV cameras seen to date, have been placed in entirely the wrong location.
