Guest oddsocks Posted July 6, 2004 Share Posted July 6, 2004 Peter, I got mine from http://www.calmar-filters.com/cctv_filters.htm but they were not cheap. I have since been told that most of the filters I purchased could have been brought from a good photographic shop(doh) Maybe worth a try? The Neutral Density filter has proved invaluable to me particularly when setting zoom lenses correctly. Paul Link to comment Share on other sites More sharing options...
Stanislav Posted July 7, 2004 Share Posted July 7, 2004 To fix back focus of auto iris lens I successfully used filters that I cut from damaged floppy diskette. Different types of floppy diskettes provide filters of different density. Link to comment Share on other sites More sharing options...

jelly belly Posted October 28, 2005 Share Posted October 28, 2005 When I first joined the CCTV trade over 6 years ago and had to work out what size lens to use. Someone gave me a cardboard disc and said, "There you go! Work it out!". With that in mind I decided to make it easier for myself and everyone else in the industry to work it out........... The result is the Graphic CCTV Lens Calculator - Please let me know what you think! Software 4 CCTV Link to comment Share on other sites More sharing options...

baywatch Posted November 8, 2005 Share Posted November 8, 2005 Looks good for explaining to end user size of images & how field of view narrows. Maybe it would be even better if little man had a fence or something behind him to explain better to end users the different views. Good luck with it Link to comment Share on other sites More sharing options...

Tagfcuk Posted November 9, 2005 Share Posted November 9, 2005 Basically a lens calculator works out what size lens you need depending on the distances and or size of area you want in your picture.So you know what chip size your using (1/3 inch), use metres, and you have measured how far away and how wide the object you gonna watch is ( 10mtrs x 3 mtrs). You want that object in you picture and its height will be say 3 mtrs, enter those into the calculator where required and calculate. it will now tell you what size lens you will need. In this case it will be a 16mm lens. They were almost essential once but now i dont know anyone that needs to use one. If a varifocal lens wont do the job then maybe you would need one but myself i sort of know from experience. If anyone wants a lens angle calculator wheel drop me an e-mail and I will post it to you with some instructions. Always find it useful when I can't get to a PC.
