USB Camera kit

I know that BI will accept a camera input on a usb port, however..... I doubt if BI would accept the combined usb feed.

Even using their dedicated software the quality would be less than 'decent', bit like a toy to be honest.
 
I agree with davep you will be sorely disappointed...Get some quality hikvision or dahua cameras...(like the hikvision 2032 or 2332 for 85 on ali express) then either run cable to it (not that hard, or hire someone) or use powerline adapters...
