Discover What Infrared is and How it Works
Infrared or IR radiation is electromagnetic radiation of wavelength that is longer than visible light, yet shorter than microwave radiation. Infrared light was discovered in the yearly 1800 by English astronomer William Herschel. The main intention was to use infrared for imaging and photography. Nowadays, infrared is being used by police or security industry to capture criminals or better protect some valuable property using infrared security cameras.
Infrared cameras produce an image of a warm object. Warmer areas have different colors than cooler ones. So such infrared devices may capture car engines heat, human or animal warmth, or any other kind of heat.
The Use of Infrared Cameras
Infrared security cameras for example, may be used in any house, business office, or even by police or military forces. The problem with regular security cameras is that they simply cant capture a quality view at night. Burglars may easily intrude into your house or office and steal your most important information or valuable items.
Infrared cameras are able to capture a heat that people produce. So even if intruders are trying to rob your house at night, these infrared cams will capture the image. Some infrared cameras may work only when theyre triggered. For example, if their sensors catch some heat around, theyll automatically turn on and start capturing the view. There are additional systems that make your life even more secure. When infrared cameras turn on, they may automatically turn some alarm system on, or wake you up if youre sleeping at home, or call a special number (security company for example) and notify them about the intrusion.
If youre thinking about the whole system of infrared security cams, then you might consider a few options available. Wireless infrared cameras should be your priority when considering your house or office security. With wireless cameras you dont need to worry about cables and all the hassles installing the system.
Such infrared cameras may be used indoor or outdoor. Of course, if youre planning to use them outdoor, you should think carefully about the alarm system. You dont want to bother your neighbors every time your cat walks around the sensors
In case, youre planning to use infrared cameras outside, make sure that theyre weatherproof. Well, usually, most outdoor cameras will be weather or waterproof. So they wouldnt get broken in case of rain or strong wind.
Infrared spy cameras are great for securing your house or office buildings. They can capture clear pictures in complete dark easily and alert when someone tried to intrude into your private property.
