Thanks a lot for the answer.
I'm comparing CCTV cameras with 1/4" lenses to cameras with 1/2" lenses, not to change the lens on a camera from 1/4" to 1/2". The cameras I'm looking at are either 1/4" or 1/2" - one system.
I rather have the feeling that 1/2" cameras will somehow be phased-out and only 1/4" CCTV cameras will remain on the marked.
So what is the difference between these two systems? Is a 1/4" camera better or worse compared to illumination and other technical data?
Thanks a lot in advance and best regards
