Camera Calculation / Design Quiz

Test how well you understand camera design and using the IPVM camera calculator to visualize video performance. Use the calculator to answer the questions.

How many PPF / PPM are the images below from the IPVM Calculator?

A shorter focal length means:

3 Your target is 100 feet from a camera. You want 50ppf on the target. What AoV should you use?*

With a 4K camera and a 90° AoV, how far from the camera (in feet) can you deliver 80ppf?

What does this snapshot below show?

Of the following, which is the best choice for the horizontal pixel count of a 4K camera?

7 You want a higher PPF / PPM but may not replace the camera. Which of this is the best option?*

What is the FoV / AoV, in degrees, of the scene from the IPVM calculator below?

You want to get facial details 70' away in an area 126' wide, as shown in the image below. What is the minimum camera resolution you should use?

If the distance to target is equal to the width of the scene at target, what AoV will it be? For example, in the scene below:

11 Which of the following is least true?*

1. The best way to determine the AoV of a camera is to enter its focal length and imager size into a calculator.
1. FoV width increases as target distance from camera increases.
1. 180° fisheye and 360° fisheye cameras with the same resolution deliver similar PPF at similar distances.
1. A 4K camera has 3x the horizontal pixel count of a 720p camera.
1. Greater PPF is needed in low light than during the day.

12 You want to get facial details of a person 500' away from the camera. What is the minimum camera resolution you should use?*
