Discrimination

In the summer when it hot, what does the temperature discrimination need to be for the animal to be detected?
Movement is detected when the temperature of the foreground (animal) is different from the background.

I think you need to go to the manufacturers page and see what the specifications are for that model

I called primos and found out I was misinformed. The motion sensors have nothing to do with heat.
Primos said most trail camera's sensors detect motion out to about 50-60 feet.

The sensors DO detect motion AND heat. That's how they work. If only motion set them off, they would take lots of pictures on windy days.
