The PennComm operations team provides emergency communications and response between all members of the Penn and University City communities and police, fire and medical emergency responders. PennComm operators, like the police officers assigned to various sectors for active walking, bike, and vehicle patrol, are trained to view the Penn patrol zone using the CCTV cameras through virtual patrol on a 24/7 basis for the purposes of crime prevention and abatement. Over 220,000 calls for service are processed directly by the PennComm Center annually, including calls for Walking Escort services. The dispatching center utilizes a state-of-the-art Computer Aided Dispatching (CAD) System to record all requests for service from the Penn Community, and is responsible for monitoring all alarms throughout campus, including burglar alarms, duress alarms and fire alarm systems.
