Replacing Lens Cover on Mini-bullet Camera
The lens cover protects the bullet camera lens from damage due to stones, dust and moisture. If the bullet camera
is mounted on the outside of the vehicle, the lens cover should be wiped clean after every session, and replaced as
necessary to ensure the camera image is always crisp and clear.
To replace the lens cover:

Unscrew the front section of the bullet camera that holds the lens cover (lens cover holder).

Remove the inner metal spacer ring, the black ‘O’ ring and the old lens cover from the lens cover holder.

Clean the lens cover holder and the ‘O’ ring to remove road dirt.

Holding by its edges, drop in the new lens cover being careful not to touch the lens cover surfaces, ensure the
lens cover is seated at the front of the lens cover holder.

Drop in the black ‘O’ ring and ensure it is seated up against the new lens cover.

Drop in the metal spacer, ensuring the shouldered end goes in first – this sits over the ‘O’ ring to hold it and
the lens cover in place.

Screw the lens cover holder back onto the camera – tighten all the way so the ‘O’ ring on the camera body can
no longer be seen.
Once the new lens cover is in place, spray with repellant (e.g., Rain-X) to ensure water does not obscure the video
image when driving in wet conditions.
Replacing a Camera Lens
All cameras are tested and focused prior to shipment. Cameras do not require focusing unless the lens is replaced
or otherwise disturbed.
To replace a camera lens:

Using a small screwdriver, untighten the lens set screw located on the side of the camera body.

Using your index finger and thumb, unscrew the lens from the camera body.

Carefully thread a new lens onto the camera body until the lens seats on the body.

Do not force or overtighten the lens.

Focus the lens (see instructions below) before tightening the set screw.
Focusing a Camera Lens with External Monitor
To focus a camera lens using an external monitor:

Connect camera to one of the four camera inputs on the TRU4orce system.

Connect an external monitor (e.g., portable DVD player) to the video out port on the TRU4orce system.

Video out cables are available at www.TRU4orce.com .

Turn on the TRU4orce system.

The video from the camera will be displayed on the external monitor.

Make sure there is adequate lighting and an object in the field of view that can be used as a target.

Loosen the lens set screw with a small flat blade screwdriver.

Turn lens clockwise or counter-clockwise until the image is focused.

When the camera lens is focused, tighten the set screw.

If you have some Loctite, place a tiny drop on the screw threads to prevent the screw shaking loose due to
vehicle vibration.

Do not put Loctite on the lens threads.
