Our half dome security mirrors are wall-mountable and provide a 180-degree angle image for an overhead view of 3-way intersections. They are ideal for surveillance and monitoring in busy shops, schools, driveways, loading zones, etc. Their lightweight material is highly reflective and increases visibility in various locations. These security mirrors help to maintain safety and productivity in the working environment as well as reduce product loss and theft in stores. Available in a smaller size, be sure to check that out.
