⚙️ Hardware Setup, Adjustments & FAQs

❓ How to adjust the focus and zoom on the 2.8mm lens? cfg_01
The 2.8mm lens is a fixed wide-angle lens and does not have optical zoom. Focus adjustment, if physically accessible on the lens, should be done by carefully rotating the focus ring until the desired sharpness is achieved. Typically, for 2.8mm lenses, the focus is pre-adjusted for most surveillance distances.
