Dome security mirrors are an effective means to protect against theft and significantly improve the view. The mirrors have a 360-degree viewing angle and a large size, which means the highest quality visibility of 180 degrees from each side of the observation. Dome mirror is supposed to be mounted to the ceiling using «Armstrong» type clutch instead of one of its sections. It has a high reflectivity and a view angle of 180 degrees from any point in the room. Any movement in the room immediately becomes noticeable to the security.
