Thanks for your reply Soundy.
The system will be used in a number of outdoors locations, business and residential.
The first and pilot project will cover an area around 10x20 metres. I think other locations may need to cover a wider area but don't know the full details yet, will find out.
I think the P1347 has 3.5-10mm verifocal lens, and the P3344 has 2.5-6 mm. It could be that these can be refocused to give the required effect. Will check.
I'm in the very unusual situation of having no budget for this project! I must find the right solution, at this time cost is not an issue.
