Cameras and recorders aimed at capturing a performance rather than producing a film. The collection currently holds the Zoom Q2n-4K, a handy video recorder that shoots in 4K and records sound through its own stereo microphones, which is the part most phones and small cameras handle poorly.
A unit like this suits rehearsals, gigs, lessons and demo clips, where the audio matters as much as the picture and you would rather not sync a separate recorder afterwards.
