A method and system for managing interference between transmission sources in an Optical Camera Communication (OCC) network is disclosed. The method includes receiving interference information associated with a set of transmission sources. Each of the set of transmission sources include a set of light sources configured to display one of a plurality of colors. The method further includes assigning a unique guard band to each of the set of transmission sources. The method includes sharing details of the unique guard band assigned to a first transmission source within the set of transmission sources with the camera. The camera is configured as the receiver of the first transmission source. The method further includes instructing the camera to accept data transmitted by the first transmission source based on the assigned unique guard band and drop data transmitted by the remaining set of transmission sources.

A passive optical methane detection and monitoring system for fixed-position installation is disclosed. The system disclosed can be a compact scannable field of view Near Infrared (NIR) filter photometer to detect and quantify methane concentration. A randomized fiber optic bundle is disclosed that can be used to direct the randomized total optical power from a collection lens to two or more isolated optical channels. Band pass filters isolate a desired wavelength range for transmission measurements for the two or more channels. Also disclosed is a dynamic detection mode that works as a flag to detect a plume of methane moving within the field of view. In other embodiments, a second methane detection device can be added at a second perimeter position to provide a three dimensional concentration grid.
