Shopping for a convex security mirror can be daunting. The related industry terms can be highly generic, broad, and misunderstood. For example, there’s no difference between a safety mirror and a security mirror. You could enter both keywords into a search engine, and myriad results appear within the blink of an eye. By typing in both words, you’ll find round mirrors, dome mirrors, rearview mirrors, traffic mirrors, etc. Most safety and security mirrors are convex. A convex mirror bulges outward, producing virtual images condensed to offer a wider field of view. See the diagram.

How Do I Choose A Convex Mirror For My 

Safety Mirror & Security Mirror Needs

A few key factors exist when determining the best convex mirror for your specific application. With so many different types, sizes, and shapes of convex mirrors & dome mirrors, it is essential to know the answers to the following questions before you procure a convex mirror for your home or office use:

  • The distance in feet the mirror will be mounted from you. For example, If you are a convenience store clerk and need to install a mirror to detect people around your beverage coolers, measure the distance from your location to where you will place the mirror.
  • A round convex mirror will cover the most distance of any safety and security mirror. They can be placed further away from you than any other type of mirror while offering the most viewing area. Use the formula 1″ of mirror diameter for every foot from the mirror. If you are around 25′ from the mirror, then a 26” diameter mirror is the smallest recommended mirror.
  • Dome mirrors (full, half, and quarter domes) will cover the least distance. For every 1′ you are from a dome mirror, you will need roughly 2” in dome radius. They work best within a range of 30,’ but 48” models can be used as far as 55′ away.
  • How much detail in the images do you need to see? For example, do you need to know to be made aware of the presence of an individual in a particular area, or do you need greater detail, such as being able to identify the individual’s name in a given area?
  • A round and rectangular convex mirror will reflect the best image resolution. If seeing objects in detail is of the utmost priority, then by all means, a circular or roundtangular convex mirror is the best choice available.
  • Know where you are going to mount your safety/security mirror. Not every type of safety and security mirror offers the same mounting options. Knowing exactly where you will mount your mirror will narrow your choices and sometimes determine exactly what kind of mirror to choose.
  • Convex round or rectangular mirrors will present you with abundant mounting options. The supplied telescopic arm and mounting brackets offer such versatility. They may be installed vertically or horizontally on just about any flush surface (walls, store fixtures, gondolas, posts, poles, sides of buildings, etc.) or hung upside down from the ceiling, soffit, overhang, or most any structure. They may also be installed directly in the corner of two intersecting walls by installing a 2X4 mounting surface in the corner.

Dome Mirrors

  • A full dome mirror may be flush mounted to a wall or ceiling or suspended from ceilings, beams, or rafters.
  • Half-dome mirrors may be mounted flush to a flat surface or hung upside down from the ceiling.
  • A corner or quarter dome mirror mounts to the ceiling of the inside corner of a wall
    Are you limited by clearance issues that will prevent you from using a particular mirror? When you establish where your mirror will be mounted, measure the area around the mirror to determine if there will be any size limitations and keep them in mind when browsing. To visualize the footprint of a circular or rectangular convex mirror, cut out a piece of cardboard just slightly larger than the mirror’s diameter you are considering and hold it up to the mounting location. A rectangular convex mirror has a low profile and is designed explicitly for low-clearance areas.
