The solar charging/recharging cam is the way to go. That was my #1 consideration since mine are deployed too far from any infrastructure and using a battery game camera just adds to the maintenance load.
I chose the inexpensive S220 cams because they fit my use case but I would expect that for your use case a different model would be needed. Here at my place I can use WiFi cams and do the nature monitoring with the only consideration or parameter that I have as a constraint being that the camera needs to be installed in a location that gets a minimum of 2 hours of sunlight daily on average.
When I first deployed one of my cams I had it in a non-optimum orientation, facing NNW instead of South so that the panel did not get direct sunlight at all. In that orientation working from a full charge on utility power pre-deployment I used the camera for two weeks before I redeployed it at the same location facing SSE. My initial plan was to position it using the Eufy mount installed on a post and the only post was N of the location I needed to monitor. After watching the battery charge cycle I determined that it would eventually discharge and require a utility top-off. I redeployed the camera on an old, cheap camera tripod a few feet from the initial location facing SSE so that the solar panel got adequate sunlight and in a matter of a few days it was topped off again.
I really like the solar powered cameras. They add flexibility to any deployment plan.
