Armed Security can be with or Without a Patrol car.
It can be With or Without a “Security style” uniform, meaning it can be like a store detective, loss prevention in plain clothes.
If you are going to need “REAL Security”, The mere Presence of a Security Officer in a uniform isn’t enough.
Uniforms: As a client, you may not want an “Aggressive” look at your site? You may want the “Mall Cop” look? Uniforms really matter when it comes to how an Officer is treated by a group of disorderly juveniles.
After all, no one wants a conflict on their property. The better the Officer looks, the better the Patrol cars look will most of the time, “De-escalate” stuff from the beginning.
