How Do You Focus Cameras In The Field?

We have recently received a Siemens Star chart that we will use for manually focusing our cameras, and we are curious as to how our users focus cameras. So we ask: "What have you found to be a de-facto solution when focusing cameras during installation and/or maintenance?". Some of our inquiries include:

  • If a camera offers autofocus, do you have a subject or chart in the middle of the image to assist in focusing?
  • If you manually focus a camera, what do you do to gauge image clarity and sharpness?
  • If you use charts to focus or test image clarity, what kind do you use?
  • If a camera gets bumped out of focus switching from day to night mode, how do you refocus the camera?

We are curious to hear responses and feedback!
