shockwave199 0 Posted February 9, 2012 Why are ptz so expensive and yet so many are only 1/4" 480 tvl? I wouldn't accept that in a fixed camera. Why is that so popular in expensive ptz's? Share this post Link to post Share on other sites
Soundy 1 Posted February 9, 2012 A smaller sensor allows for a smaller lens... a smaller lens is lighter and thus easier to move around at high speed. I don't know how BIG a factor that is in designing them, but I'm sure it's a part of it. Share this post Link to post Share on other sites

Dan, didn't you look at that elaborate post on the subject of camera specifications. As a comparison, Super VHS only hits 420 lines. You continue to tout camera specifications as if they mean anything.
