The adjustment screws are located below the camera’s lens. They MUST be loosened using a small screw driver before attempting
to adjust the zoom and focus otherwise the screws will snap off and the camera will no longer be able to be adjusted. Be certain to
gently tighten the screws once you have set your desired zoom and focus as vibrations may otherwise cause the camera to slip out of
adjustment.
INTERNAL ADJUSTMENTS
While most “bullet”-style cameras such as the QH8005B will have their lens
adjustments on the outside, dome cameras like the QH8006D and QH8008D
and the bullet-style camera QH8005B have their adjustments inside their cases,
right on the lens assembly itself.
Dome Cameras
There will be screws on the camera’s case that will be needed to be unscrewed
in order to remove the upper portion (the portion covering the lens).
IMPORTANT! Before adjusting the zoom and focus on the camera, you MUST first loosen the screws on the
respective adjustment rings. Failure to do so will result in damage to the camera.
Bullet Cameras
The adjustment knobs will be located on the lens assembly inside the camera
so the lens cover must be first removed to gain access. If there is a removable
sunshade, it should also be temporarily removed for easier access to the lens
cover.
Once the lens cover has been removed, you will see the adjustment screws
located behind the cameras lens. They MUST be loosened using a small screw
driver before attempting to adjust the zoom and focus otherwise the screws will
snap off and the camera will no longer be able to be adjusted. Be certain to gently
tighten the screws once you have set your desired zoom and focus as vibrations
may otherwise cause the camera to slip out of adjustment. When replacing the
lens cover take care to make sure there aren’t any fingerprints or dust on the
inside that will obscure the lens.
