This is a very nice 2.0 mega-pixel camera with enough resolution to meet these requirements. For example, the Sony SNC-EM630 IP camera has a resolution of 1920 x 1080 pixels. We can now select a camera that has at least 1600 horizontal pixels. (Field of View) x (pixels/ft.) = Horizontal Resolution Use the following formula to calculate the resolution of the IP camera: We can start with the field of view and then calculate the resolution of the camera.

We can also do this calculation in reverse. And, a 10-megapixel camera, with 3648 x 2752 pixel resolution, provides a 45.6 ft. If we have a 5-megapixel camera with a resolution of 2592 x 1944, then the widest horizontal field of view is 32.4 ft. If the camera resolution is 1920 x 1080 pixels (2-megapixel), then our widest field of view is: = Field of Viewįor the following example, let’s assume you would like to identify the face of a person you already know. Total Horizontal Resolution / Pixels per ft. The following formula is used to determine the field of view: How wide a field of view can we see and still be able to identify a person’s face? To calculate the widest field of view, divide the number of horizontal pixels (available from the camera) by the pixels/ft. We consider this higher pixel count to be more of a forensic identification than a personal identification. But, if you need to identify a person you don’t know then you need a lot more resolution. (260 pixels/m) to identify someone you know. We determined that if there is good light you will require about 80 horizontal pixels/ft. In a previous article, we discussed the resolution required to identify a person’s face.

Especially in case of very small working distances of several centimetres, the calculated values are no longer realistic. The calculated working distances refer to the optic centre of the lens housing. By means of additional spacers, however, the lens distance can be reduced ("see calculation of close-up rings"). In case of F-mount lenses and other lenses for larger image circle diameters, the minimum lens distances are often considerably larger.
