Truth be told, I’m not much of an outdoorsman, but I do like to take hikes in the nearby county park once in a while.
I was out there last week, and happened upon a couple of guys working with something that turned out to be a trail camera. It turns out they worked for the county, and were setting up these devices on the trails to monitor wildlife during the night hours.
(Lest you were concerned, they were deactivating or taking them done during daylight, when people were around. The park is closed at night).
Anyway, I was somewhat aware of these gadgets, but after chatting with these two, I got curious in how they work. While I’m not in the market for one myself, the technology brought out the geekiness in me.
An initial online search turned up a site called TrailcamPro.com, which tries to help folks find the best deer camera for their needs. Their buyers guide page, however, gave me some good, basic info on how these things do what they do.
In essence, they’re digital cameras controlled using infrared light. When something moves in front of the infrared beam, it triggers the camera shutter and zap … a great image of the neighborhood deer. Their infrared capabilities also allow them to take photos and video at night, even without a flash.
The intricacies of these devices rather impressed me, though. For instance, depending on what you’re buying the game cam for, you need to consider things like the detection angle (who wide a range the infrared beam covers), the field of view (who wide of an angle the camera lens will cover), and the detection range (how far from the camera the beam reaches).
Actually, after learning more about them, I can see where I might find a trail camera useful for security purposes on my property. Maybe I’ll have to read a few reviews. Hmm …
