Philadelphia police will debut a new surveillance system at Sunday's Blue Cross Broad Street Run.

Sentry is a portable, wireless system that can record happenings at considerable distances from atop a trailer. The hope is that the new system will keep an 'eye' on areas with no existing surveillance system.

The Sentry system is just one of numerous tactics and strategies police will employ to assure optimal vigilance in the wake of last month's Boston Marathon bombings.

So where are the systems located? Police aren't saying, of course. But the department has expressed a desire to have similar setups at all outdoor events in the near future. Four such devices will be on hand to monitor the United States Open golf tournament in Merion next month.
