Focus

[Angel1403 0]

Hi there,

 

I just got a new high res bullet camera with 16mm lens. It was great. However, a little to close to subject.

 

I unscewed the 16mm lens and added 12mm lens. However, I cant get a clear image???

 

It looks like I would need to screw the lens in further than it will go to get a clear image???

 

Is there a special way to add a new lens so that focus is good/clear?

 

Cheers

 

Allan

Is that a "D" mount lens you are using? also do you have the special tool that should have come with your new lens to make proper adjustment on the camera?

yeah some of the IR Color Bullets come with those, the one I had was the 100' OEM IR one, had a 16mm fixed lens and tried to claim that IR, got one from a client to install, it stayed out of focus until I chucked it in the garbage can

You need to make sure you’re getting the right type of lens mount. Find out what type you have. Is it a C-mount or CS-mount?

 

You probably should buy a varifocal lens that will let you have some flexibility of zooming in and out.

 

This way you will be able to adjust it to your liking.

Those bullet and board stylr usually use a "d mount" type of lens.
