hi there
my company is participating in a convention next month, i am setting up a small stream station for them
i'll be running vMix from a 2014 macbook pro (win10 in dual boot) as the stream station, but i am having some problems in chosing the best cameras for the task

i'll need 2 wireless cameras that i can capture their 1080p stream on the notebook, the first one will be mounted (probably with a power bank attached) to stream an overview of the attendance
while the other will be handheld with a mic for some quick interviews

so whats the best cameras for the task, and how can i get a clear sound for the interview's scene ?

with regards
ahmad

note: its an indy type of project, nothing pro is required
