Using mirrors to help ensure a safe, trouble-free environment is good practice. When positioned appropriately, security mirrors can alert personnel of danger or theft. These mirrors are also useful in factories where foot and forklift traffic can cross paths, in offices where blind intersections and corners exist and at front desk/office locations that must be able to view normally blocked access areas. Security mirrors come in dome or convex configurations. The most commonly asked questions that apply to security mirror selection are what type of mirror, convex or dome style, what material of construction should be selected and where the mirror(s) should be placed for maximum viewing.

If an application calls for the need to view objects in some detail further away than 6m, then a convex mirror is suggested. A convex mirror has a curved mirrored surface that allows for the reflective surface to project toward a light source. Convex mirrors reflect light outwards, they are not used to focus light, and therefore act similar to that of a standard mirror. Convex mirrors form a virtual image of reflection since the focus and the center of curvature are both imaginary points inside of the mirror. When trying to view and pinpoint a particular area, use a convex mirror. Since the lens of a convex mirror is curved less than that of a dome style mirror, the image in the convex mirror appears larger and less distorted. Convex safety mirrors allow for 160 degrees of vision, and can be used to view at an angle to reduce accidents around blind corners and doorways. As an example, convex mirrors are effective when viewing aisle traffic in a store or warehouse.

Convex mirrors are offered in circular or round rectangular shapes. Round rectangular convex mirrors are an ideal choice where hanging in low ceiling areas is necessary. Convex mirrors come in several materials and can be used for both indoor and outdoor applications.
