While there are a number of solutions available for detecting intruders at outdoor sites, using a thermal video camera with video analytics has become a strong contender as the best choice. That’s because thermal cameras act like a perfect human detector. All things give off heat energy, and thermal infrared cameras used for security applications operate right within the human temperature range. Because they rely on heat energy rather than reflected light, they work in complete darkness or in bright sunlight, making them excellent 24-hour solutions. They also work well in bad weather like fog or snow, and will ignore things like headlights sweeping through the scene or reflections that trigger false alerts for visible cameras.
Using A Thermal Video Camera for Perimeter Security
Recent developments in thermal video camera processing take perimeter security to a whole new level with unparalleled video analytic accuracy and clearer thermal images at costs that bring these capabilities to affordable prices. New generations of thermal cameras use very powerful on-board image processing to exaggerate small differences between the temperature of an intruder and the background, providing very detailed detailed information for making accurate video content analysis with much fewer nuisances.
Long-Range Thermal Video Cameras Reduce Cost
Another advantage common to thermal cameras is the impressive detection range and area coverage. Some thermal video systems can detect intruders at distances that can exceed 500 meters, which yields a direct economic benefit: Fewer cameras are needed to protect large outdoor areas, with a big decrease in infrastructure and installation expense. In fact, cost advantages now make it possible to introduce the highest levels of thermal video analytics to a whole new range of commercial perimeter security applications.
