That sounds weird as far as the LED's.. Wonder if they made a design
change.. On mine, the PIR sensor is the large sensor to the left
and of the same size as the lens opening. On mine, the left LED
is red and is the trigger indicator, and the one on the right is green
and is the delay/not ready indicator. I cover both of mine and it has
no effect on the camera. But like I say, on mine and all others I've
seen, it's the large sensor next to the lens which is the PIR sensor.
The LED's shouldn't have anything to do with that, unless they
changed the design some way.
This is a pix of mine. I cover both the LED's with those little
rubber feet they sell for project boxes. They are bright and
will scare varmints. The PIR sensor is the white looking large
sensor to the left of the lens. It determines day/night by the
amount of light it sees. You will also notice that the camera
auto adjusts the image lighting. Also for video's.
