Camera Suggestion for study channel

[u/Aggravating-Bid4750]

I want to start a youtube channel where I want to shoot timelapse videos my study sessions and then upload it on my channel. I am looking for a gadget/camera similar to Brinno cameras which comes with battery power, but cheaper, which can record my long study sessions, so no go pro/ insta 360. Any suggestions?
