How far can a WiFi Security Camera signal go?

Episode 1636 (58:20)

Todd from Portland, OR
WiFi

Todd has built a WiFi based security system and he's been able to get reception at a distance of a half mile. Leo says that's incredible. But if you have an unobstructed view line of sight, it may happen. But any kind of metal in between can cause that range to lower, or the bandwidth quality to drop, especially when transmitting video. Leo says you could try moving the stations around to get a better line of sight connection.
