In the View area tab the schematic view of the camera view area in the horizontal and vertical planes is displayed.
The image in the View area tab represents two projections of view area, parted by the horizontal black line correspondent to the ground in the vertical (upper) projection.
The red lines mark the sizes, the green dash lines specify auxiliary constructions, the dark blue lines designate the camera tilt angle, and the turquoise ones mark the space bounds of camera view area. The actual projection of view area (if it exists) is filled by grey color.
The camera location and calculated parameters are displayed in the text boxes next to the camera icon and the red dimension lines. The parameters in the white boxes can be changed, by choosing them from list or by typing. When any of the parameters is changed, the values of the rest parameters are recalculated.
The parameters in the grey text boxes are results of calculation and can be changed only through changing the parameters in the white boxes. |

The linear parameters are input and output in meters or feet according to the measurement system set. The angular parameters are input and output in degrees.
When an incorrect value is entered the box turns red. When an incorrect value ratio is ensued from the input, all boxes with the values of mutually incorrect ratio turn red. If the calculation with incorrect values is still possible and has sense, the program nevertheless performs it. In this case check the results carefully.
If the image of view area changes radically with new values, the image in the View area tab changes correspondingly, thus the arrangement of parameter boxes are changed too. Watch carefully the image changed, since with the image alteration the parameter boxes might interchange their positions.
According to the obtained sizes of the view area projections, you can draw the projections in any graphics program. Then, moving and combining the obtained projections on the site plan, you can achieve the optimal number and location of cameras in the project.
In VideoCAD software, these view area projections are drawn automatically.
View area of panoramic cameras occupies half of space. Its shape does not shown on the View area tab.
Instead of it the fish eye is displayed. |
