Learned everything in the field including CCTV, alarm, access control, ATMs, locks/vaults, and other miscellaneous things. Management is great, easy going yet organized. Hardest part of the job is needing to get creative with certain tasks. The most enjoyable part is the people, along with seeing all sorts of different things that many people don't get to see.
Reasonable schedule, company vehicle.
Sometimes there are very long hours, but that is always compensated.
