Took your advice went ahead and got another lens, as this lens does seem to be causing most of my problems currently for detection. Now that I have reconfigured the system to have the camera a little closer (Distance mentioned above) I now cannot seem to get the camera to focus decently at all with the wide angle lens so I have ordered this one the only major difference I see is this is a 1.3mp lens and my sensor is 2.0mp but from a quick study online it seems 1.3mp will work fine with 720p video as long as I don’t plan on viewing in 1080p:
After hours of trying to learn how lenses work with sensors as most info online pertains to large sensors like those of photography cameras, I came to the conclusion with the info you provided this will probably be the best option to try. Just not sure about the working distance as it doesn’t mention it but when using a calculator online I found, I input my specs and the lens specs and came up with this info at 40mm working distance which seems fine as my ROI is about 1" x 1" area at distance 40mm.
Let me know if you see any errors in my ideas thank you!
