Depends on how much acreage you are covering and your objective. Checking SD cards on all those may prove pretty intrusive depending on placement.
I had lots of cameras like that in the early days and I had to ask myself this question: How much time am I spending dealing with camera issues, changing batteries, and checking SD cards that could be better used in other QDM efforts? For my objectives, the loss of data for trending analysis and time I was spending dealing with these redirected me toward a different approach. I'm still running a dozen cameras across a little under 400 acres, but they are high end wireless cams that run 24/7/365 with out significant data loss. My focus now is further reduce visits to these by installing larger solar panels and larger capacity batteries.
It really depends on what you are trying to accomplish.
Thanks,
