I would be amazed if that could do 100' in open air much less through walls. Those things are usually low end consumer models and would have a real hard time operating in any commercial type environment.

We actually tested those cameras in house here. Found the had so much distortion that we couldn't make anything out on the picture... And this was at a distance of 10', with line of sight. The manufacturer told us we must have a defective unit, so we sent it back, and haven't heard boo from them in the last 3 months.

Chinese Lenses they sell too, from emory they look just like Computar too the T!

I would stear away from them, they send me emails almost every day

I have only seen 2 good wireless options and both were expensive the first is from Extreme and is quite good indeed the second is made here in Australia and I have sen it work up to 4 KM (no bull) they used it at the Sydney Olympics.
