I bought a Dahua Starlight IPC-HDW4231EMP-ASE and I wanted a higher focal length lens so I bought a 16mm M12 lens like this: Sunvision CCTV HD 5MP 16mm Monofocal Fixed Iris 17⁰ AOV Board / M12 / MTV Lens | eBay
But now I'm having trouble installing the new lens. I was able to remove the old one, but the new one won't screw on. It almost starts, but then immediately gets too tight to go on. When I look at the new lens and the old one, it almost looks like maybe the threads on the new lens are smaller.
Is it possible this lens has a different threading? I thought all M12 lens were supposed to be compatible?
