One of the most important characteristics, affecting the efficiency of a video surveillance system, is the ability to distinguish objects at different distances. The program allows you to see which parts of the camera field of view have the required resolution to identify, recognize, detect, monitor different video surveillance objects (in particular, people or cars).
By default the program shows camera zones according European Union standard EN 50132-7 from 2013. There are several types of zones as listed below:
Strong identification zone (purple). In this area there is 100% identification of the object, eliminating any doubts. Pixel density = 1000 pixels per meter. This zone is usually not recommended, as it needs very powerful equipment and increases project cost significantly.
Identification zone (red). In this area you can positively identify a person beyond reasonable doubt. Pixel density = 250 pixels per meter.
Recognition zone (yellow). In this area you can recognize a person known to you. Pixel density = 125 pixels per meter.
Observation zone (green). In this area some details of the individual, such as clothing, can be seen. Pixel density = 62 pixels per meter.
Detection zone (light-green). This is area where you will be able to detect presence of a person. pixel density = 25 pixels per meter.
Monitoring zone (blue). This zone is used to monitor the traffic flow or the movement of people without the need of identify specific objects. Pixel density = 12 pixels per meter.

On the "Site plan" and "Camera installation drawing" tabs the camera zones are highlighted with the same colors.
If you want to change values of pixel density for zones or to use a different standard, you can do this by opening "Settings" > "Visualisation of camera zones"
