Choosing a Convex Mirror

Choosing a Convex Mirror

Modern organisations can choose from a range of effective security technologies, and most employ multiple methods to decrease the likelihood of robbery, theft and unauthorised entry. One of the most popular and effective security devices is the convex mirror. Convex mirrors are usually fastened to corners (particularly blind corners) as a valuable component of any security plan.

Convex Mirrors: How Do They Work?

The premise behind the convex mirror is simple: these dome-shaped mirrors allow an individual to see around a sharp corner without stepping into it. Convex mirrors are also useful weapons against shoplifting because they enable security guards to scan for criminal activity while remaining hidden to potential shoplifters. For even greater security, many firms mount a tiny video camera opposite the mirror and film everything displayed in it. These videos can provide crucial evidence in a criminal trial.

Strength and Resilience

Modern convex mirrors are more than just bulging glass disks. Many are shatterproof and can withstand several direct hits with a baseball bat or crowbar; others are not made from glass at all, but from a strong, lightweight acrylic that has the added benefit of being much lighter than traditional glass convex mirrors. Lighter mirrors are less likely to be ripped away from the wall by their own weight, and pose a reduced risk of serious head injury if they do fall.

Purchasing Considerations

Most modern convex security mirrors are crafted from acrylic; others are polycarbonate. Customers should investigate each material before making their purchase decision, asking themselves questions such as these:

  • Will this mirror change colour over time? (Polycarbonate mirrors often turn yellow after several years).
  • Is this mirror coated with a protective film that may eventually peel off?
  • Will this mirror be used for indoor or outdoor use? Does its material stand up well in such conditions? What about in extremes of temperature?
  • Based on the company needs and the intended location of the mirror, would it be best to purchase a mirror with a steel or hardboard backing? What about a mirror with no backing at all?

Premium Features

Many convex mirrors offer an even more extensive list of features. For example, they may be coated with a scratch-resistant topcoat or imbued with a chemical-resistant compound that helps avoid damage by acid, tear gas or similar substances. Normal mirrors may pit or grow discoloured when exposed to such substances; the pitting renders the mirror ineffective because it no longer reflects a clear image. Chemically resistant convex mirrors are much more likely to remain usable after chemical contact; while they are slightly more expensive than a standard convex mirror, they are decidedly cheaper than replacing the entire unit. It's important to note that glass convex mirrors are naturally scratch-proof; all others must be coated with a scratch-resistant substance.

The Sensible Choice

Convex mirrors are far and away the most popular mirrors used in security applications. They're affordable, effective and can be simply installed, eliminating the need to pay a contractor or handyman to mount the mirror. It's easy to add convex mirrors to any security plan; in terms of cost versus crimes prevented, these mirrors are amazing investments.
