A security camera needs to be set so that its angle of view includes the area from a doorway to the edge of a parking lot. T
The doorway is 16m from the camera. The edge of the parking lot is 24m from the camera. The doorway is 28m from the edge of the parking lot. What angle of view is needed for the camera?
Sorry that's the rest of the question
To set a security camera with the desired angle of view, you will need to consider a few factors such as the camera's focal length, sensor size, and distance from the target area. Here are the steps to determine the required specifications:
1. Determine the distance from the camera to the farthest point you want to capture within the parking lot. Let's call this distance "D".
2. Measure the width of the area you want to capture, from the doorway to the edge of the parking lot. Let's call this width "W".
3. Calculate the required angle of view using trigonometry. The formula is:
Angle of View = 2 * arctan(W / (2 * D))
This formula accounts for the fact that the angle of view is the angle from one edge of the captured area to the other, and that the camera's field of view forms a triangle.
4. Determine the specifications of the camera that will provide the desired angle of view. Different cameras have different sensor sizes and focal lengths, so consult the camera's specifications or user manual to find the necessary focal length or angle of view.
5. If you have a camera with a fixed lens, check if the calculated angle of view matches with the camera's specifications. If there is a discrepancy, you may need to adjust the placement of the camera or consider using a different lens with a suitable focal length.
6. If you have a camera with a variable focal length (zoom lens), adjust the focal length to achieve the desired angle of view.
By following these steps, you should be able to set up a security camera with the correct angle of view to include the area from a doorway to the edge of a parking lot.
