Netvision 360 Security Group offers fire detection and fire risk detection through its specialized fire detection thermal cameras. These cameras incorporate a fire detection algorithm, making them more versatile systems providing both safety and security of equipment and personnel. The fire analytic algorithms can detect an active fire with the Active Fire Detection Algorithm as well as detect when a fire is about to occur with the High Risk of Fire Detection Algorithm so that fires can be prevented and contained with minimal or no damage to facilities.
Fire Detection - Detects fires even without smoke present at up to 6km away, day or night
Risk of Fire Detection - Detect a potential fire before it occurs or monitor equipment for thermal failure
Multiple Alarm Types - Visual, Serial Communication, and Contact Closure alarms signal an alarm state
The proprietary Fire Detection algorithm is able to detect and identify a nearly unlimited number fire sources while avoiding false alarms from hot spots in the scene. When Fire Detection is implemented in the Accuracii PTZ camera system, one camera could be used to monitor several preset locations and a limitless number of fire sources. When panning and tilting, the camera requires 5 seconds after each movement to detect a fire in the new scene. The Fire Detection algorithm is accurate at detection large fires at up to 6km in the longest range configuration.
The High Risk of Fire algorithm (often called Hot Spot Detection) is able to examine a scene and determine which pixels have exceeded a user-defined temperature threshold. Once set, the algorithm will show the area that exceeds the user-defined threshold as a red pixel that so that it is clearly visible in the video image. In the image at right, the coffee cup and soldering iron have exceeded the user-defined threshold of approximately 93° C (200° F). An ambient temperature adjustment, available in the configuration settings, can increase reliability in some situations.
Electricity Substation Monitoring
The system can monitor the temperature of sensitive equipment at electrical substations and then automatically send alerts to trechnicians when equipment is reaching its failure point. This will allow technicians to be dispatched to repair the equipment before a failure happens, preventing power loss to the grid.
Flame Out Monitoring
The Fire Detection algorithm has the ability to be used in reverse, meaning it can detect when a flame is missing. This is often used for on or offshore oil drilling sites, the camera can alert of a flameout to improve site safety and avoid fines by environmental protection organizations.
