Wrens are really cute tiny birds...are they common where you are?
But how do you run the wire out to the birdhouse? Is it under or over ground, and how is it protected?
Wrens are common in Ohio... but they're our first nesting pair on our lot. We also have a Blue Jay family at the other end of the yard. We feed, provide fresh water, have planted, and provided houses to attract the birds. We have a nice selection in the yard and we enjoy their visiting.
That particular camera is wireless (regular X10 color cam). Although I am also wired so I can run ether wired or wireless. I originally had two cameras in that area and ran plenty of extra wires. The extra wire was a good thing... as a critter quickly chewed up the beige (root colored?) cable that came with one camera. Extra wire is coax, CAT5, and a run of landscape lowvoltage wire. I buried the wire in a shallow "spade trench".
The yard was struck by lighting 2-3 years ago... and it killed every camera I had. When I replaced the cameras I found better places for cameras... and replaced one camera with two... in two different places. I like to have my cameras... in view of other cameras (the cameras watch each other... as well as the house). I have to make a real effort to limit the number of cameras I have. Most of the outside of my home is covered by motion sensors and cameras.
The wireless camera is received by a receiver I mounted in the eves about 60 feet from the camera. The image is then sent through the house via video cable (then even as channel 3).
