Check availability of facilities for video recording
Do you know if a wired LAN exists in the 3 rooms ? If you can (but's that's quite early), please try to find room maps showing audio and video gear location
Usually we need a strategic location with a small table where cables arrive with a copy of signals (XLR from mixing device, > HDMI from HDMI splitter, ethernet cable to the LAN, ethernet cable running to the back of the room for the network camera, > power access). The machines and camera we usually take in the plane.
Alternatively, if they have HDMI cameras we could also capture them instead of the IP cam.
Microphones must be provided, they basically need XLR for the whole audio part available and then use that.
