Did you ever hear about Thermal Cameras? If yesthat's good.if not.now is your chance to know few cool stuff about them.
Ok okfirst of all; What is Thermal Security Camera?
Thermal security cameras are imagers that see heat, or thermal energy, in an object. The human eye cannot detect thermal energy. This energy does not get to the retina because the eye's lens and fluids absorb it. Thermal security cameras allow users to see what their eyes cannotinvisible heat radiation emitted by all objects regardless of lighting conditions. Thermal cameras form video pictures based on the small temperature differences between objects.
Thermal cameras are extremely effective security tools in any environment. The technology can readily detect intruders and other potential hazards.
Awesome Info about Thermal Cameras
Thermal security cameras don't suffer from the limitations of visible light imaging: light availability and contrast. First, thermal cameras don't need reflected light energy. The technology sees heat given off by objects. Everything you see normally creates heat energyday and night, in good and bad weather.
Not only do warm-blooded creatures produce their own thermal energy, but in doing so, create contrast. What's more, energy seen by thermal security cameras generally creates a better image at night than during the day. The cameras work during the day. As long as there is the smallest amount of temperature contrast between a target and its background, you can see it, but the technology is designed to work best at night.
But there are other technologies available that can help users see at night, thermal camera technology has some distinct advantages. To understand the differences between the technologies available, users need to understand how each operates, and the inherent advantages and disadvantages.
What light has to do with anything here?
The most common way facilities cope with the darkness of night is to install many powerful lights that generate enough visible light energy for daylightor even lowlightcameras to work.
The lights and camera combination has a number of disadvantages. Not only is this combination expensive, but there are many areaslike waterfronts and wetlandswhere the two are not practical. Obviously, lights have uses, they are effective and efficient in small areas, and they act as a deterrent. Whether lights actually help security professionals see anything with a daylight camera is, at best, debatable.
How about Night Vision Goggles?
Night vision technology, whether used in goggles or as a discrete camera, works essentially the same way as any other visible light imaging system. Receptors magnify small amounts of visible light thousands of times so objects become visible at night.
But night vision systems have the same weakness as a regular TV camera; the dependence on visible, reflected light. Similarly, too much light can overwhelm the system, causing "bloom" and reduced effectiveness. Because night vision technology needs a minimum amount of light to work, conditions, such as heavy overcast and light fog, can severely limit effectiveness.
What are Infrared Illuminated Cameras? And how do they work?
Infrared illuminated cameras also are sensitive to reflected light energy, just like an eye. As with other visible light imaging systems, infrared illuminated cameras starve for light at night and can't make a usable image without help. The technology compensates by transmitting energy that reflects off the objects within the camera's view and using those reflections to make a picture. Unfortunately, even reasonably powered illuminators are weak, resulting in severe range limitations. The range of performance relies on the reflected light energy limited by the strength of the energy being reflected.
Thermal security cameras are the only solution available today providing an affordable alternative to visible light imaging. Thermal cameras work day or night, require no special lighting or infrastructure, are not range-limited by sunlight, and have better contrast than visible light cameras. The technology also is immune to almost all forms of camouflage. With the advantages, thermal security cameras are a solution to any nighttime imaging problem.
So I guess the answer is .YES.Thermal technology is pretty COOOOOL
