Its a camera that you can control. Pretty cool.
The Detroit River Watch Web Cam is based on a Canon VB-C10R camera. This system was chosen for its high performance 16x zoom and good low light capabilities. The high speed internet connection is sent wirelessly to the museum, a location not served by wired high speed service. The traffic is sent some three miles from downtown Detroit by Zing Detroit.
