With a CCD (charged coupled device, a digital image processing method) camera, an auto iris lens is required to perform day/night imaging.

Network cameras allow you to post your image to the internet without the use of a computer by connecting directly to your network router. Continuous live images and configuration menus can be viewed from anywhere by entering the Web Cams IP address in a web browser.

Network Web Cams also provide ftp (file transfer protocol) client capability, allowing you to automatically upload images to your own website or free hosting services.

The higher the value, the more saturated the color.6. Haze subtraction improves the contrast of an image automatically.7. Jpeg (Joint Photographic Experts Group) is a standard web image format.

Jpeg Quality provides a balance between image lossy compression and image quality.

Look for hosting services that archive your images, create daily time lapse images and integrate weather data with weather cam images.

A webcam is a video camera that feeds or streams its image in real time to or through a computer to a computer network.

Setting the iris properly will extend the sensor life.4. Most cameras require external enclosures to operate in extreme hot, cold and humid environments. The amount of detail that the Web Cam can capture is called the resolution, measured in pixels.

The enclosure doesnt help in cold environments unless the enclosure is completely sealed (which can cause condensation on the window) or contains a blower. The more pixels a camera has, the more detail it can capture and the larger pictures can be without becoming blurry or grainy.2. Exposure range is a function of lens aperture (the amount of light it gathers) and shutter speed (how long light is gathered), expressed in seconds.

The iris automatically opens and closes according to the changes of the light conditions.

If the light level is low, the lens iris opens up to allow enough light for optimum picture quality, and when the light level is high, it closes the iris so that incoming light does not overwhelm the Web Cam and blur out the picture.

802.11 communicates at 2.4 GHz and is designed to work with other 2.4 GHz devices, such as telephones and wireless computers.
