Premier Mounts recently launched a series of security center mounts that are designed to set up small NOCs (Network Operation Centers) on a desktop. The multi-monitor mounts come with a variety of mounting bases, arms and mounting heads and fit any multi-monitor project design. Up to nine displays can be mounted on to a single pole, allowing for multiple arrangements depending on installation requirements and number of displays.
Premier says the multi-monitor mounts have more than 50 pre-configured combinations.
