The camera seems to work just fine at below freezing temperatures. Placed near a deer path through the backyard, it captures….deer! What one can learn from these photos is of biological interest (at least to me): e.g., time of day they wander down this path, and which deer are using it. In this case, it confirms what other sources tell you about deer preferring to forage near dawn and dusk.
I also got quite a few blurry photos at night when the deer walked too fast for the camera to capture a good image. But the time record allows one to monitor activity. The camera takes pretty sharp photos in the daytime, like the one of me below.
It also took several photos in the daytime, when there was no subject in the field of view. Perhaps whatever it was moved out of the field of view too quickly. It takes at least 10 sec for the camera to capture the first shot.
I’m glad this system works so well, but now I just need to find the path that the fox uses.
