Web Cams?

100 feet is easy if you use a directional antenna. You would need a router that you can change the antenna on though. Two directional antennas with line of sight aimed at each other can span something close to a mile, maybe more.

That being said I wire mine. Just ran cat5 along with my power wire in the ground. I think it was less than $10 in wire to go 75 feet. Now I need to move the incubator out there an get more cameras.

An alternative, and this will really drive your DH crazy, is to dig a very narrow trench, lay down 3/4" plastic conduit/pipe, and run 100 or 200 feet of ethernet cable, so the cam is hard wired; also run electric cord to plug in the cam. (actually you might need two pipes, I don't know if the electric cord next to ethernet could cause interference).

Cams over ethernet are much more reliable, smoother image, than wireless cams.

You want an IP cam (your router gives it an IP address and so you can view it on your computer and set it up for web viewing), the more common DVR cams you proprietary systems that feed into dvr recorders and little TV monitors, much harder to find a way to feed those into an internet connection. With IP cams it's pretty easy to securely view them over the web or on a smart phone.
