A fixed focus lens has one set focal length with a specific field of view which cannot be changed. Any camera without a varifocal or power zoom has a fixed focus lens. All cameras offered a AutomatedSurveillance.com with fixed lenses are focused to infinity. This means that although the user cannot manipulate the field of view, everything in the picture beyond a few inches will be clear and in focus. Objects simply get smaller as they move further away from the camera (unlike a camcorder which may be focused only on a small area with blurred vision of the video image in the foreground or background of that area).
