General Questions
The alarms are automatic, and therefore, there is no need to watch the screen.

Unlike infrared cameras, the GCI not only detects gases in the infrared but also their unique spectral signature. This allows the system to automatically remove false alarms such as steam, rain, snow, clouds, moving people, cars, etc. Each of these sources generate an emission/absorption signature that is substantially different from that of the hydrocarbon gases—their “fingerprints” are different. The GCI uses advanced algorithms to identify hydrocarbon fingerprints and automatically alert operators to potential hazards at their site.

Infrared cameras are gaining in popularity, but they have their pitfalls. All of them require user interpretation to determine the presence of a gas cloud. Some companies are tying them into their analytics, but the low image quality coupled with the fact that the cameras cannot differentiate between steam and other gases leads to many false alarms. Furthermore, the infrared camera systems cannot determine the concentration of the gas, and therefore cannot be calibrated to alarm only at specific thresholds.

Rebellion Photonics’ Gas Cloud Imaging system is a one-of-a-kind, automated gas leak detection system. The snapshot GCI system utilizes proprietary hyperspectral imaging technology with advanced detection algorithms to pinpoint and quantify leaks. With the ability to distinguish between steam and hydrocarbons, GCI system is the next generation for leak detection and monitoring at all points of the petrochemical industry.

Different chemicals have different minimum concentration levels. For example, the GCI camera detects ammonia at 13.5 parts per million and methane at 250 parts per million. The alarm threshold is almost always set much higher than our minimum detection value, otherwise there are too many alarms for operations to usefully handle.

A single GCI camera can cover a huge swath of a facility because they can be put on a pan/tilt mechanism that allows them to pan up to 360 degrees.

The customer can choose when to alarm, when to record, and what to record. Customers can set alarm thresholds for each chemical based on concentration levels and direct cameras to image a specific area or establish a preset scan path for the cameras. Customers also have the ability to download raw data and run long-term trend analyses. Site names and settings are also customizable.

Our cameras are used in all weather conditions, including sleet, rain, snow, fog, heat, humidity, etc. Our Gas Cloud Imaging (GCI) systems not only detect gases in the infrared, but also their unique spectral signatures. This allows the system to automatically remove false alarms such as steam, rain, snow, clouds, moving people, cars, etc. Each of these sources generate an emission/absorption signature that is substantially different from that of the hydrocarbon gases—their “fingerprints” are different. The GCI uses advanced algorithms to identify hydrocarbon fingerprints, which can be detected through all elements of weather, and automatically alert operators to potential hazards at their site.

Yes, fully automated, there is no need for the camera to be continuously monitored by an operator as alert levels are programmed directly into the system.
