Has anyone used/got experience with these

1. At the bottom of the picture above " SW80" there is a motor driven worm wheel, what is it for, how is it controlled if required.

2. Also the Line lock buttons next to the dip switches what are they for.

3. The lens holder is a quick release type, this unit came with the green module (13mm x 1.0 thread), I need to find the Black module (I think) (12mm x 0.5) does anyone know if they are available without having to buy the lens as well.

I cant find anything in the 17 page booklet that came with it!

I've never come across your camera but..

The motor will move the ir cut filter. Most likely it will be controlled by the camera based on light level.

Line lock is a feature used to sync multiple cameras for use with analogue switches. It isn't used much nowadays. I'd suggest you set it to Internal or crystal or off.

I not sure on this one but I'd expect the lens holder isn't available off the shelf.

many thanks.
