Full-dome, half-dome, quarter-dome, and anti-shoplifting dome mirrors for retail stores, warehouses, offices, and institutional buildings — from lightweight acrylic ceiling-mount domes to heavy-duty stainless steel mirrors for high-abuse environments. Supplied and installed by RPS Building Specialties across Southern California.
From full-dome ceiling mirrors to corner-mounted quarter-domes, we supply and install the complete range of indoor security and convex mirrors.
Circular dome with complete surround view, ceiling-mounted. 18"–36" diameters. Ideal for intersections, lobbies, and warehouse areas requiring full 360-degree surveillance coverage.
Semi-circular dome, wall-mounted for hallways, corridors, and T-intersections. 18"–36" diameters. Provides wide-angle coverage of approaching traffic from both directions.
Corner-mounted design that monitors two intersecting aisles simultaneously. 18"–26" sizes. The most space-efficient option for right-angle intersections in retail and warehouse settings.
Dome and half-dome mirrors purpose-built for retail loss prevention. Lightweight acrylic construction drops directly into standard suspended ceiling grid systems for tool-free installation.
Shatterproof flat mirrors for security checkpoints, lobbies, and under-vehicle inspection. Provides true-to-size reflection without the distortion of convex surfaces.
Standard convex mirrors for warehouse aisles, hallway blind spots, and corridor intersections. 12"–36" diameters with adjustable mounting brackets for optimal viewing angle.
Choosing the right mirror material determines durability, optical clarity, weight, and suitability for your specific indoor environment.
Select the correct mirror diameter based on the viewing distance required at your specific location. Larger mirrors provide greater range and a wider field of view.
| Mirror Diameter | Viewing Distance | Typical Applications |
|---|---|---|
| 12" | Up to 15 ft | Small retail aisles, office doorways |
| 18" | Up to 25 ft | Standard retail aisles, hallway intersections |
| 24" | Up to 35 ft | Warehouse aisles, wide corridors |
| 26" | Up to 40 ft | Large retail spaces, warehouse intersections |
| 32" | Up to 50 ft | Wide warehouse aisles, large open areas |
| 36" | Up to 65 ft | Large-scale warehouses, distribution centers |
An honest look at indoor security mirrors — what they do well and what to keep in mind when specifying them for your facility.
Indoor security mirrors are one of the most cost-effective safety and loss-prevention tools available for commercial and industrial buildings. Unlike electronic surveillance systems that require power, wiring, monitoring, and ongoing maintenance, a properly placed convex or dome mirror provides instant visibility around blind corners, down aisles, and across open areas with zero operating cost. Whether you manage a retail store concerned about shoplifting, a warehouse where forklifts and pedestrians share aisles, or an office building with blind corridor intersections, indoor security mirrors improve safety and situational awareness from the moment they are installed. RPS Building Specialties supplies and installs all types of indoor security mirrors across Southern California.
Full-dome (360-degree) mirrors are ceiling-mounted and provide a complete surround view of the area below. They are the standard choice for four-way intersections, open retail floors, and warehouse areas where traffic approaches from all directions. Half-dome (180-degree) mirrors mount flat against a wall and cover a semicircular field of view, making them ideal for T-intersections, corridor ends, and wall-mounted retail surveillance positions. Quarter-dome (90-degree) mirrors tuck into a corner where two walls meet and monitor both intersecting aisles simultaneously — the most space-efficient option for right-angle intersections. Each type serves a specific purpose, and the correct choice depends on the geometry of the space and the angles that need to be covered.
Acrylic is the most widely specified material for indoor security mirrors. It weighs 3 to 5 times less than glass, is virtually shatterproof, and is the most economical choice. Glass mirrors offer superior optical clarity and scratch resistance but are heavier, more expensive, and breakable. For high-abuse environments such as correctional facilities, psychiatric wards, and juvenile detention centers, stainless steel mirrors are virtually indestructible — though they sacrifice image quality. Polycarbonate mirrors bridge the gap between durability and clarity, offering 250 times the impact resistance of glass while maintaining better optical quality than stainless steel. RPS can recommend the right material for your specific environment and budget.
Indoor security mirrors are part of a complete safety and visibility program. RPS Building Specialties also supplies and installs parking garage mirrors for vehicle traffic visibility, outdoor safety mirrors for exterior blind spots, and wall mirrors for restrooms and commercial interiors.

Common questions about indoor security mirrors answered by our safety and security mirror specialists.
For retail shoplifting prevention, full-dome (360-degree) ceiling mirrors and half-dome (180-degree) wall mirrors are the most effective options. Full-dome mirrors mounted at ceiling height provide a complete surround view of an entire department or aisle area, making them ideal for open floor plans. Half-dome mirrors are better suited for wall-mounted positions at the ends of aisles where staff need to monitor activity from a checkout counter or service desk. Lightweight acrylic anti-shoplifting dome mirrors are specifically designed to drop into standard suspended ceiling grid systems for quick, tool-free installation. For maximum deterrence, combine dome mirrors with strategic placement at high-theft zones — the visible presence of a security mirror is itself a proven loss-prevention tool.
The correct mirror size depends on the viewing distance required at your warehouse aisle intersection. For standard warehouse aisles (up to 35 feet of viewing distance), a 24-inch convex mirror is the most commonly specified size. For wider warehouse aisles or intersections where forklifts need visibility up to 50 feet, a 32-inch mirror is recommended. Large distribution centers with wide lanes may require 36-inch mirrors for up to 65 feet of viewing distance. As a general rule, larger mirrors provide greater viewing distance and a wider field of view, but the mirror must also be mounted at the correct height and angle to be effective — RPS can assess your specific aisle layout and recommend the optimal size and placement.
Acrylic security mirrors are the most commonly specified material for commercial and industrial applications. They are 3 to 5 times lighter than glass, virtually shatterproof, and the most economical option. The primary tradeoff is that acrylic scratches more easily than glass and has slightly lower optical clarity. Glass security mirrors offer superior optical clarity and scratch resistance, producing a sharper, more distortion-free reflection. However, glass mirrors are heavier, more expensive (typically 2 to 3 times the cost of acrylic), and breakable — making them unsuitable for environments where impact is a concern. For most retail, warehouse, and office applications, acrylic is the recommended choice for its combination of safety, weight, and value.
Indoor dome mirrors are typically mounted to ceilings using one of three methods depending on the ceiling type. For suspended (drop) ceiling grids, lightweight acrylic dome mirrors can be placed directly into the grid opening, replacing a standard ceiling tile — no tools or hardware required. For hard ceilings (drywall, concrete, or plaster), dome mirrors are secured using a mounting bracket with screws and appropriate anchors for the ceiling substrate. A chain or cable safety tether is often added as a secondary support. For open-structure ceilings with exposed joists or beams, clamp-style brackets attach the mirror directly to the structural member. RPS handles all mounting methods and ensures the mirror is positioned at the correct angle for maximum viewing coverage.
Yes. For high-abuse environments such as detention facilities, correctional institutions, psychiatric wards, and juvenile halls, stainless steel security mirrors are virtually indestructible. These mirrors are fabricated from polished stainless steel sheet rather than glass or acrylic, so they cannot be shattered or broken into sharp fragments. The tradeoff is lower image quality compared to glass or acrylic — the reflection is serviceable but not as sharp or distortion-free. Polycarbonate mirrors offer another high-abuse option with 250 times the impact resistance of glass while maintaining better optical quality than stainless steel. For environments that require both durability and reasonable image quality, polycarbonate is often the best compromise between indestructibility and optical performance.
