Lens calculator: AXIS 210, AXIS 210A

The focal length of the delivered lens is 4.0 mm. Keep this value or enter the focal length of the new lens if you want to find out at what distance to place the camera in order to capture a specific scene. You can also calculate the focal length of the lens you need by specifying the actual distance and scene dimensions. 

Please enter the length values (distance, width or height) specified in the same measurement unit, e.g. meters or feet.  The focal length of the lens is always specified in millimeters. Click the button right to the parameter you want to calculate.

Width: (m / ft)		Distance: (m / ft)
Height: (m / ft)
		Focal length:  (mm)

Example: If the focal length is 4.0 mm and the distance to the scene is 8 meters, the calculated width and height of the scene will be 7.20 and 5.40 meters, respectively.
