Leveraging its experience in camera image analysis and intelligent algorithms, Dahua Technology has developed thermal imaging devices with innovative functions that balance visible light with infrared, enabling the ability to effectively monitor an area under all lighting conditions. These functions include intelligent temperature measurement which further extends the scope of surveillance applications such as detecting forest fires or quickly checking for passengers with high fevers at international airports.
The following three applications demonstrate the widespread capabilities of thermal imaging devices:
- Border security
Dahua Technology has created a comprehensive solution to tackle the challenges of border surveillance. A thermal dome camera (TPC-SD8320) with 30x zoom installed at every 1km of a 100km section of essentially unlit, wild border terrain can quickly detect objects and then confirm threats using visible light images. In this way, just 100 cameras alternately placed on both sides of the border are necessary to provide full coverage, which can be managed by a small team of workers from a command center. The center is outfitted with an e-map, which shows the location and current sight line of each camera, allowing border workers to assess surveillance coverage in real-time. When a camera detects someone entering a restricted area, it will automatically trigger an alarm while continuing to track the target. Staff can then alert the intruder and warn them with sirens. If needed, a team can then be quickly dispatched to confront the intruder. In addition, intelligent route patrol allows operators to configure cameras to follow a set patrol route according to the requirements and the terrain, decreasing the need for manual control.
- Forest fire prevention
With the potential of having catastrophic consequences, fires are the greatest danger to a forest. Efforts to prevent forest fires have been explored over the years, but several difficulties still exist – the area of the forest is disproportionately large to the limited number of patrols who move relatively slowly and are equipped with only their eyes, from which a fire source is very likely to escape detection, especially when smokeless. To effectively prevent forest fires, new technologies that can function more accurately than humans are needed.
Dahua’s intelligent forest fire monitoring system automatically monitors the entire forest area, conducting intelligent patrols. If a blaze begins, the system will automatically trigger an alarm via a high precision intelligent algorithm which uses laser positioning to accurately locate the source of the fire.
- Substation inspection
As power transmission hubs, substations must maintain a safe and stable state at all times. Manual patrol alone is not enough since malfunctions can happen in an instant and may not be immediately detected, or a patrol may not be able to see silent breakdowns waiting to occur.
Fortunately, new devices allow us to use technology in order to detect problems. Dahua has developed an intelligent substation monitoring system which provides intelligent patrol features complete with a report after each round of patrolling. In other words, it provides users with real-time information about substation equipment in a way that is much more efficient, saving time and labor. Furthermore, it allows humans and machines to work together and take advantage of their respective strengths. If the temperature of equipment or part of the station exceeds a preset limit, the system will automatically trigger an alarm alerting management.
