I agree with you Lolo Wolf about using IR!!
The cheap one use 35mm film which means you have to wait before you can see your snapshots.
Digital ones will allow you to see them as soon as you hook them up to a computer.
The ones with LCD screens built in will give you instant access to your snapshots!
( I am not shouting, this is a cut and paste)
ONE FAILURE OF GAME CAMERAS IS THAT PEOPLE POINT THEM AT AN AREA. WHAT IS WRONG IS THAT THE ANIMAL (OR HUMAN) COMES FROM LEFT "STAGE" AND EXITS RIGHT "STAGE".
YOU WILL NOT GET A SHOT BECAUSE OF THE TIMING. YOU MAY GET A PICTURE OF THE TAIL OF THE ANIMAL!
POINT THE CAMERA TOWARDS LEFT, OR RIGHT OF THE "STAGE". NOW THE ANIMAL SETS OFF THE "TRIGGER" (MOTION), AND THEN THE CAMERA GETS THE SHOT AS THEY KEEP APPROACHING! HOW IS THAT FOR SIMPLE? THIS IS A COMMON FAILURE FOR NEWBIES.

The Memo Cam would be perfect for the "Gotcha" shot!
