iPad Air 2 video

Ok…I’m using a Roland V-HD1 video mixer that is output into a BlackMagic Ultra Mini Recorder that then outputs to a 2015 iMac using mimolive. Does anyone out there want to talk me into or out of using iPad Air 2 devices (running into the Roland via hdmi adapters)as video cameras in my under-funded school tv studio? Thanks for any advice (either way) that you might have.
