A video security system can be quite pricey therefore it is a good idea to have a degree of understanding in regards to what the system is capable of achieving. The most beneficial point to start at is defining what you need the system for. That could appear self evident but there are 4 main criteria's we define a security camera as being for.
1. Observe the what is happening in an area
2. Detect the presence of people in a scene
3. Recognize a person you know
4. Detect the presence of people in a scene
Often you'll actually want more than one of the above within the same area and may be assuming just one camera will be able to cover your requirements. Around 90% of applications you will require at least a couple of cameras unless you want to be among those images you see on TV of a pixilated person, that you have zero hope of recognizing.
Designing first with a 3D CAD helps to test the scene to determine the right camera resolution, lens and location to give the desired results. This will save you relocating or replacing cameras later on.
In part 1 of the following video, we look at the basic steps to add a background from a map or floor plan, get an accurate scale, start to place cameras allowing us to get a good idea of what the camera will see.
The next part explains the above mentioned four coverage definitions and the way to set the pixel/metre ratio for each. Once set, we can see from the shaded coloured areas as to where in the scene you will achieve each level. The tools to create 3D objects, walls and people are also shown in this section
The final part takes us over the comparing of different mega-pixel camera resolutions and what happens to the image when you electronically zoom in. It is not going to be what you see on CSI shows but rather divide the resoultion by 4 every time you double the zoom.
