I would almost be willing to bet it is a Moultrie Game Camera.
I have heard that a lot about that camera.
I have a Non-Typical DeerCam and it has a Heat and Motion sensor so it takes pictures of Heat in Motion. (people or animals)
I would definately recommend this camera. It is selling for around $229.95 right now. A little bit more than the Moultrie but a lot better quality.
I have never got a picture where some bushes or trees set off the sensor to take a picture.
good luck!
