Many available web cams are designed to be used outdoors and do not require weatherproofing. If the camera you select is not resistant
to bad weather conditions consider shielding the unit in a clear Plexiglas case. The camera can "see" through the thermoplastic but is protected from the elements. This method of protection is the one employed by the Kodak bird cam. (The Plexiglas will need to be cleaned periodically to keep the transmitted image clear.)
Positioning Web Cams
The positioning and placement of your web cam is important to maximize your bird watching experience. Obviously bird cams should be aligned in such a way as to view the entire bird feeder or bird bath but also consider how the sun's movement in the sky will affect the image. You don't want your web cam "looking" right into the bright afternoon sun. Try to get as near to the feeder or bird bath as possible. The birds may need a day or two to get used to this strange new object in their environment, but most species will quickly learn to ignore the presence of a bird web cam.
