    I already have 11 cameras covering my property, 9 are @EMPIRETECANDY (Andy) supplied 5442's and very happy with them. I like the larger sensor size of the 5442 but now I'm looking at purchasing two LPR cameras. From my understanding, a 2 mp camera, zoomed in (most likely a variable focal...

    I'm tired of messing with camera-based motion detection. No setting is perfect, or durable-- when I achieve something that looks like it works, the seasons change and the leaves fall off the trees, or a spider weaves a web over a camera, and everything stops working again.
