I had my SD49225T-HN since 2016 and it's been pretty good except it occasionally restarts itself. This hasn't been a big problem since the downtime is brief and it always comes back up just fine.... until last week. Now when the camera is restarted either manually or because of a problem, it looses nearly all it's settings except for the IP settings. I'm wondering if there's some sort of battery in the camera that maintains the settings during a restart. If so, does anyone have any pictures of it or know what kind of battery it is?
