Setting up a Barn WebCam - Part 4
There are a wide variety of camera lenses that you may want to consider when setting up your barn webcam.
The first one that I would suggest you find is an Auto-Iris lens. This lens automatically adjusts the amount of light coming into the camera depending on how much light is outside. So if it is darker outside, the auto-iris will open up larger to let more light in so the picture isn't so dark. And if it is very bright outside, the auto-iris will close smaller to let less light in so that the picture doesn't get so bright that you lose the details. You will want to make sure the auto-iris lens is compatible with the camera you purchase, as different auto-iris lenses are designed to work with different models of cameras.
If you want your camera to pick up a larger pen, or area outside, here is a lens I found very helpful. My expectant-momma pen is a small paddock area with a run-in shed for shelter. I keep my expectant jennets in that paddock for at least 2-3 months before their due date, so I want it to be as big as it can be while still being all in the camera field of vision. I added a wide-angle lens to my camera, and it picks up a much wider area allowing my jennets more space to live while awaiting their baby's arrival.
If you have your webcam set up in a smaller space like a foaling stall in your barn, depending on where your camera is located in conjunction with your jennet's stall, you may not need a wide-angle lens to pick up the whole area.
There are a wide variety of other lenses available for CCTV cameras. With a quick search on Internet or a visit to your local security camera store, you can find quite a bit of information about these other options. But for now, I have found the Auto-Iris lens and Wide-Angle lens to fill my needs well.
