difference between IR Camera and CCD Camera in CCTV System?

Hi !
Can anyone help me in finding out the explanation between IR Camera & CCD Camera. I need to prepare a project report on this, please

IR = infrared, refers to the frequency spectrum of light (color). There are two commonly used IR bands for imaging. Near-IR is just outside the region of colors we can see. People use near IR to take interesting pictures and can be used to view an unlit area, as perceived by humans, that is illuminated by a near-IR light (humans can't see the near-IR light source). This has been used in wildlife photography and surveillance. Thermal-IR is a spectral band where heat is emitted. Thermal-IR is far away from our visual capability. This requires a special imaging sensor and lens. Thermal IR cameras image the heat radiated off surfaces. These cameras generally start off at $10,000 for cheap systems.

CCD = charge coupled device, a type of image sensor used in cameras. CCD sensors can sense light in the near UV down to near IR. CCD sensors can't be used to image thermal-IR. Filters are usually placed in front of the sensor to block UV and IR so just the visible spectrum is sensed.

There is lots of information about light spectra and CCD image sensors on the Web.

With a range of many products to their name Fujifilm is one of the well known names in the manufacture of digital cameras. However, they have not been in the market for a budget priced range until recently to compete with the dominant names known to produce budget ranged digital cameras.

The FUJIFILM J10 digital camera rivals pretty well with other known names in design and convenience and are most certainly competitive in their pricing structure. Yet, even though it is not something that would want you to get excited about, it matches up to its functionality in value as a low priced digital camera that an amateur can well afford.

In regards to functionality even though it does not excel in any particular area, the FUJIFILM J10 digital camera has some excellent built in scene modes. But to access these, may sound a bit complicated as they are buried in the vast menu.

Shutter speed depending on exposure is 8 seconds to 1/2000 seconds. Focus is auto focus (center)

White balance is set at automatic scene recognition and is preset to fine, shade, fluorescent light (daylight), fluorescent light (warm white) fluorescent light (cool white), and incandescent light. Auto flash. Flash modes are auto, red eye reduction, forced flash, suppressed flash and slow synchro.

With all these and many more features the FUJIFILM J10 digital camera is a versatile camera for the price.
