The soundscape of surveillance cameras is complicated and is obnoxious to the animal world. Noisy, hard to hide and off gas odors. Spiders and ants enjoy the magnetic fields from the batteries. Some plastics off gas formic acid and that translates to the smell of bee hives and ant hills= bear snack. I am not aware of any reports of an anteater going after a trail cam like bears do. Just an FYI; polypropylene and noryl do not off gas or absorb moisture. Cases made of PP by SeaHorse and Pelican have their place. Those cases have thick walls and do well to attenuate ultrasonic noises.
I am reminded of an incident years ago involving trail cameras and small diameter trees in a shallow root ball environment. The researcher checked on the cameras and found the trees had been pushed over and the cameras were aimed at the ground.
The statistics for trail camera sales need different categories. Not everyone is monitoring for a hunting season. Trail cameras are purchased for home / property security. Years ago, trail cameras were very expensive and the selection was limited. A cursory check of on line vendors shows a huge inventory, made overseas and many available for about $50.
I have been watched putting up trail cameras and placing food. They spy on us and spying on them is difficult.
