The day begins with a review of the past twenty four hours and a briefing from the out going security person. Next is a review of the activities on campus for the day ahead looking for special activities that might require advance set up, etc. Then it's off to patrol and check in at all the work places where employees will begin to congregate, opening doors, turning off alarms, etc.. Then to do the building checks where the residents live, looking for any signs of a person in need of assistance. From there on it's a patrol on bike, or foot and monitoring the emergency radio for any calls.
Management of time is required so that you can be at specific places on schedule. My co-workers are aware of time as well, so we move along. The hardest part of the job is the long day (24 hour). Relief comes for the night, but you are still on call at your place of rest.
The best part of the job is you only work two shifts a week and you have time off to do other things.
