Wifi (not cellular) camera systems

[Palmetto Bug]

I know I've read about off-the-shelf cameras that "bridge" and communicate with distinct channels to other linked cameras. One main camera can be cellular or linked to your home base station wifi and the others have peer to peer wifi connections to each other daisy chained across the property.

Special antennae may also help you link across distances. Wifi is usually broadcast omni directionally with a donut shaped signal but it can be pushed over longer distances with the appropriate directional antennae. There's a pretty famous hack for directional wifi antennae you can find if you google "pringles can antennae". Some guys I worked with built one and it was surprising the number of SSID's you could see and connect to from a high vantage point in the city.
