1. Know when to be seen – Criminals are less likely to target an area anytime a security guard is clearly visible. During the daytime you will want people to see you as a deterrent. At night you will need to decide what is best for your situation. Should you use the cover of darkness to observe, or is it better to be seen so that you don’t surprise an intruder? Remember, you must be safe to be effective. See the next section, How do I patrol safely? for more information.
