Hello everyone, I have been following the conversations about ip cameras and looking for a few. I noticed that many of them list a 3.6mm lens almost as standard on the company websites.
I found an interesting graphical representation depicting the lens size, view angle, and distance of coverage and from that I derive that it might be best to have an 8mm manually focused lens. I assume this as I want to be able to see a face clearly within a distance of 7 to 14 meters. Another thing that I noticed is that not all camera mfgs indicate whether or not their cameras use varifocal lenses.
So my question is how to obtain other sized lens or even varifocal lenses? Secondly, what might be the cost of an 8mm lens?
