(I may be mistaken, but...) The Download page has links only to the "current firmware" for cameras. My guess is that support can provide a link to older firmware (or explain how to accomplish what you want to do).

I would email the problem to support@reolink.com They are in Hong Kong, which may be many time zones away. I always get a detailed response within 24 hours.
