Get To Know More About Infrared Cctv Camera.

When people think of infrared cameras they are generally thinking of one of two types of infrared cameras, so if you are installing the camera or selling them a camera it's necessary to know what they are thinking. If you don't know what they have in mind, even if they sound supremely confident, you might want to (carefully) ask them what they want out of their "infrared" camera. A minute spent here will pay off in the long run to make sure you and your customer are "on the same page", and it will help you avoid a possibly costly embarrassment.

FLIR and Security IR Camera Confusion

First shown on television and in crime and military movies, the garish red, yellow, green and purple display of the FLIR (Forward Looking Infrared, or Forward Looking Infrared Radiometer) camera comes to mind when many laypeople think of "infrared camera". FLIR cameras have a very expensive video sensor array (and support circuits) that detect infrared emissions from any area where the camera is pointed. Any warm person, animal, or object generates (emits) small amounts of infrared light. Hot objects emit more IR light than warm and cool objects/areas respectively. The difference in the amount of IR light emitted translates to the colors shown on a FLIR display.

FLIR cameras are used in a wide variety of private, commercial and industrial settings. Consumers and professionals use them for building inspection, safety, emergency and hazard prevention and identification. The real-time display available on many FLIR camera designs gives the user immediate feedback and allows them to pinpoint and correct issues that are often invisible to the naked eye. Subtle differences in temperature can even allow contamination to be detected in all kinds of materials, including foodstuffs. Since physical contact is not required, FLIR devices can capture and monitor temperature readings from distant objects that would be inaccessible or even dangerous to approach (such as bearings in a working turbine or fixtures and objects in contaminated areas that are dangerous to the health of human workers).

The second type of infrared CCTC camera in Dubai - the kind that make up the backbone of surveillance systems in millions of buildings around the world - is less flashy but more far more cost effective. This type of camera has an infrared sensitive video sensor somewhat like a FLIR camera, but is a far cheaper variant. More importantly, instead of depending on the weak infrared light generated by warm objects, IR security cameras depend on reflected infrared light.

Since there's not enough ambient infrared light even on the hottest and brightest days (but then why would you be using an IR camera in the hot sunlight anyway??? not to mention the sun is down at night, duh), cameras that depend on reflected IR light require a LOT of IR light to work. That is why many IR security cameras contain a built in array of infrared LEDs or require an external radiant IR source.

All of the IR security camera products they supply fall into the second category of IR camera. They are not FLIR-type CCTC camera in Dubai. Since they depend on reflected IR light, most of the cameras contain a built-in radiant IR LED array - those that do not require an external source of IR for imaging at night.
