The following video is parts of Saturday's apartment building fire that was captured by the Waukesha Police Department's downtown OptiCop, a surveillance camera that is controlled by dispatch.

Deputy Chief Mark Stigler provided Waukesha Patch with hours of footage from the fire, including these clips. Stigler said that the instant the 911 call came into dispatch, the dispatchers were able to focus on the fire.

The cameras helped with keep track of the fire's intensity and the location of the firefighters as they were rescuing six people from the burning building and extinguishing the blaze.

Stigler said the cameras have been used to capture images in dozens of incidents since beginning the program nearly two years ago and Saturday's fire was the biggest incident caught on camera so far.
