Also very interested in PoE cameras with open source firmware. Most of these seem to be wifi + power cable; I figure if I'm running a cable anyway it might as well be a data cable. Maybe wifi is easier to set up a couple devices, but once you get to 5+ cameras PoE is worth.
Hard wire your cameras and have a blinking red "recording" light that actually only responds to wifi jammers which cause it to stop blinking. They think they got the cams down, and stroll on unaware.
Then they don't even realize the real camera isn't visible. It's next to that big obvious one.
