Thermal Cameras: How Are They Different From Night Vision Cameras?

Thermal Cameras: How Are They Different From Night Vision Cameras? Thanks to modern technological advancements many IP surveillance cameras do not require perfect lighting conditions. These cameras can be useful even under dark conditions and may provide key information on intrusions. or suspicious activities. As the need for surveillance and monitoring under difficult conditions has increased, manufacturers have come up with various new technologies to make sure that the lack of proper lighting doesn’t hamper the operation and performance of security cameras. Thermal cameras do not use visible light for detections rather the heat radiated from people, autos, and animals to make detections on intrusions and activities in areas under surveillance, even in complete darkness. Two major technologies are available to enable surveillance in dark. These are thermal and IR night vision. There are differences occur between these two technologies. Let’s find out more about them. Night Vision Cameras Night vision cameras emit near-infrared radiation. The camera is very sensitive to this light, picks it up, and then amplifies it to capture activities. Thermal Cameras Users must understand that the word “camera” can be used in their context for sales and marketing, but actually; they are thermal sensors rather than actual cameras they are sensors that detect heat emitting from any object. They sense heat and not the visible light. The heat can be infrared or thermal energy, both parts of the electromagnetic spectrum. While a camera can detect only visible light, thermal sensors can see thermal energy. Thermal

sensors can detect more than just plain heat, they can detect tiny differences in thermal emissions, even fractional degrees, like 0.01 °C, and display them either in grayscale or shades of different colors depending on how the user wants to see the display. Simply put, it is based on the fact that everything on earth emits some form of heat. And different materials absorb and radiate heat and different rates, which forms the basis of these sensors (cameras). Thermal Radar a U.S. manufacturer located in Orem Utah, produces a continuous 360-degree thermal sensor or camera for effective surveillance in both daylight and in no-light conditions. This allows the user to monitor a much larger area than a fixed or directional thermal camera or a night vision camera. Source Url- https://bit.ly/3irPb9F
