Before you say, "they're everywhere". Here are my requirements
1) Wireless (not essential but desired)
2) Something that a non-electronics geek can follow
3) Hardware that I can actually PURCHASE (no I can't buy this obscure wireless doorbell anywhere even if I could follow the directions)
Is there anything like this because I haven't ran into anything except for, "oh yeah I just got a dog shock collar", "oh, a remote control car works great". Is it just that all camera-nerds are also electronics-nerds or something?
