Okay, it doesn't state on the box for the existing cam, but the new cam box lists "Passive infrared sensor (PIR) activates when motion and heat are detected". The cam i have been using, the on switch states "PIR". So mudfork may have a point. If there is a snake slithering through, it may not have enough heat to activate the cam. i'm not sure what to do about that, unless the rat and the snake get into a wrestling match . . . . .
