Every time you pull out of the parking lot at a mall, you see these big convex shaped mirrors. These mirrors are for your own safety. They work on a very simple physics principle. This is perhaps the cheapest way for security at different places.
Mirrors are often assumed to be made only from glass. Hence the fear of it breaking is always there. With advanced research over the years, you now have acrylic mirrors. These are durable and sturdy. They do not break upon impact very easily. Probably if a truck runs over it or the world’s strongest man punches it, it might just have a crack on it. There are also metal based mirrors made from highly polished steel or stainless steel. These mirrors do not break very easily as metals are malleable. But if repeatedly damaged, it may look like a piece from a broken disco ball.
There are many kinds of security mirrors. Here are a few of them for the best safety solution.
- Convex mirrors:
- Tinted mirrors: You might have come across these mirrors in movies. You see the detective interrogating a criminal; the other detectives stand behind the mirror and watch the interrogation. This is not exactly a mirror, but normal glass coated with a mirrored tint. These are used for security purposes in different places like police departments, offices, etc…
- Inspection mirrors: At a security check point you see a guard with a little trolley like apparatus with a mirror facing upwards at the bottom of it. These mirrors help the guard check for any suspicious materials or items under the car like a bomb, etc… This is the easiest and fastest way for a security check.
- Dome mirrors: Dome mirrors are the most efficient type of security mirrors. There are three basic kinds of dome mirrors depending on the necessity:
- Full dome mirrors: these mirrors provide a full 360° panoramic view. Full dome mirrors help you in cross intersections, or large hallways.
- Half dome mirrors: Half domes provide a 180° angle view. This allows you to have a clear view at ‘T’ junctions.
- Quarter dome mirrors: These mirrors have a 90° viewing angle. At ‘L’ turns, this mirror gives you enough viewing for your safety.
- Flat panel mirrors: These mirrors can be mounted in various places including the ceiling. The idea of having this mirror is to have a closer look of things in a subtle way.
Although security mirrors have their cons, the pros are that they are cheaper and do not use any electricity. Unlike security cameras, mirrors are easier to install and easiest to use. No worries of cables running around the office space or home. Just mount it be safe and free.
