For years I've had a Sharx wireless indoor HD camera on the inside of my window with front porch, yard, and some of the street in view. It's worked well and has pretty good quality. I have it setup with a user-defined motion-detection box drawn over the front porch so any movement on the porch triggers 30s of video and 3 snapshots being ftp'd to an ftp site, as well as the 1st snapshot being emailed to me. The capture settings are pretty configurable via the camera's web interface (motion-det-only/constant recording, ftp, email, quality, etc). Since it's on the inside, the physical installation was pretty easy. Attached with bracket to wall, plugs into the nearest outlet, and connects with wifi to my home network. The camera has infrared leds for night vision but I have them turned off b/c they just reflect off the window. Fortunately there's a street light in front of my house that provides sufficient lighting.
