Assembly

Preparing the lens

Punching out the filter

Start by removing protective covers from the sensor and lens. Take care not to touch the sensor after this!

The cameras come with an IR Block filter in the lens holder. We don't want this, so unscrew the lens from the holder and using a screwdriver, carefully punch out the filter as shown in the image on the right. Make sure there are no shards left.

On the underside of the lens holder you'll see two plastic nubbins. These get in the way, so using the wire cutters. snip them off, then screw the lens back into the lens holder.




Attaching the lens

Attaching the Lens

Carefully unclip the circuit board from the plastic holder, but DO NOT detach the ribbon cable. Using the supplied screws, carefully attach the lens to the sensor board.

Now clip the circuit board back into the plastic housing.








Preparing the Camera Housing

Glands in Place

Fit the small cable gland to the housing and the ends of the PoE cable up through the smaller cable gland, but don't tighten it up yet.

Fit the large cable gland in the other opening, and push a piece of plastic packing foam into it. This is to keep insects from getting in, but allow moisture out.
