I have a selection wheel made by Pentax that I got from one of the trade shows. I just looked to see if was available online but didn't find it. Here is another one I had saved: https://www.silentwitness.com/support/lens/lenses.php Rule of thumb: -if you want features such as facial, clothing, license plates, go with a narrow view eg. 12mm. It will take more cameras to cover the area though. -if you want wide area coverage (see movement, but lose detail) go with 3.5/4mm. These are the units that are in the "cctv in a box" that are available to the DIYer.

the view finder is nice, but i usually buy a varifocal lense. they will work on 90% of the sytems you install. there are those certain situation where you will need a specific lense, and that is where the view finder is awesome. it gives you a chance to show customer, and have them decide what they want.
