12.3.1 Horizontal lens coverage in actual figures
All figures in the table below represent (calculated) approximations for
the three camera examples. Numbers may vary slightly due to the
cameras' electronics and optics.

Examples for selecting the right camera for your purposes
Example 1:
What is the lens coverage for a distance of 12 m and the camera version
EC-710-081 ?
Lens coverage = distance x field of vision (at a distance of 1 m)
Lens coverage = 12 m x 1.7 = 20.4 m horizontal lens coverage
Consequently, an area (lens coverage) of about 20 m can be monitored.
Example 2:
You need to monitor a vat that is five metres wide and situated about 5 m away from where the
camera is installed. The image of the vat should fill the screen. Which camera version is the most
suitable for this application ?
Because the drawing of the horizontal lens coverage is true to scale, you can place a true-to-
scale object representing the vat inside the drawing and move it to achieve the optimum position
and thus select the best camera version for your purposes.
For this example, this would be the EC-710-070.
