I've been using the Sebectec software for over two years. It's impossible to beat the quality of a digital camera. With Mike's software, you can set it to take images a frequently as you'd like, and the software will create time lapses, which are really cool. Click on my signature to see the pictures and time lapses.
I have my camera mounted inside in a window using a Panavise 809 suction cup mount. To eliminate reflections at night, I have a shoe box taped to the window over the camera and mount with painters tape.
I highly recommend Mike's software. He's very responsive to requests also.
