Probably just use your phone, with either a cube on the back so it doesn’t fall down or a tripod of some sort, just make sure the tripod is not ridiculously big for the table.
if you have an iphone, those are pretty good for videoing solves. you can download an app called ClipyCam so you can pause your camera, allowing you to do a solve, pause the camers, do another solve, and so on. Also, this thread should probably be on Off-Topic.
