I can see where using a cell cam, false triggers could be a major problem ($$$).
Actually, the false triggering problem
CAN be much less an issue with cell cams.
Typically, a particular cell cam will have such a high monthly limit for pics that significant false triggering for a day or two is not necessarily going to cost any more $.
The advantage of the cell cam is that you find out very quickly you have a false triggering problem, and then can immediately remotely change the cam setting to either eliminate or reduce the false triggering.
The one cell cam I have now that's false triggering between 8:45 am and 9:45 (due to the rising sun hitting it), it goes from a 30-second triggering interval to 10 minutes at 8:30am to 4pm (or whatever time I set for it to revert back to 30 seconds or less between events.
False triggering is actually a bigger problem with non-cell cams for me.
Most of my cell cams "report in" 2 to 6 times daily, depending on application & purpose.
The above mentioned one is currently set to 2 times daily, so I get a report @ 8:30 am as to what's happened since 4pm the prior evening. Another report comes in at 4pm.
I rarely use the "instant" reporting setting simply because it drains battery life so much faster, and also because I seldom need to know "instantly". Just depends on the application.
