I was looking for a light weight good quality camera for Quadrotor FPV and came up with this solution from china got immediate reply from sales it is just 120$(sensor board+wifi+lens)
Complete accessories and price list is here ipcam.PDF
And product is listed at
Never purchased anything from china before so little bit scared for loosing my money However if this device really have all these specs then it is a great replacement for costly Go-Pro,What do you say???
