Im installing an IP Camera security system for a friends new music studio. They would like a video camera system to record musicians playing drums, piano, singing etc and provide video on USB drive at end of session. Also, live stream video and audio via website if they want. Im thinking of buying HDMI video cams and put them on mic stands. Then run HDMI to an interface box of some kind. NewTek Tricaster looking interesting, but not sure about the 5-7k pricetag not including cameras. Anything out there that can do this? Thank you for your help!
