This tool helps you easily calculate the minimum resolution and focal length needed for your surveillance camera setup.
Camera Field of View Calculator
This calculator helps you determine the field of view of your camera based on the focal length of the lens and the dimensions of the camera’s sensor.
How to Use It
- Enter the focal length of your camera lens in millimeters (mm).
- Enter the distance to the subject in meters (m).
- Enter the width of your camera’s sensor in millimeters (mm).
- Enter the height of your camera’s sensor in millimeters (mm).
- Click the “Calculate” button to see the horizontal and vertical field of view in degrees.
How It Calculates the Results
The calculator uses the following formulas to determine the field of view:
- Horizontal FOV:
(2 * atan(sensor width / (2 * focal length))) * (180 / PI) - Vertical FOV:
(2 * atan(sensor height / (2 * focal length))) * (180 / PI)
Limitations
This calculator assumes a rectilinear lens (not a fisheye lens) and does not account for lens distortions. The calculated field of view is an approximation and can vary based on the actual camera and lens combination.
