A webcam is simply a miniature video camera that either feeds or streams a video or image to either an internal computer or to a personal computer via the Internet. Webcams are usually small, portable cameras that sit on a small computer board, mount to the user's computer monitor, or are automatically built into the system itself. They can be used for a wide variety of purposes, from surveillance and security to marketing and education. However, there are many different types and models of webcams, each offering something a bit different in terms of capabilities and features. Knowing which type of webcam you need will help you make the right choice.
One of the primary features when shopping for a webcam is the optical lens. The most common type of optical lens is a simple circle. However, if you need a digital form of this lens, which provides a greater field of view, then opt for one with at least nine pixels in the digital form. These digital cameras also have sensors built within the lens itself to automatically adjust the focus as your face changes.
Types of lenses in Webcam
There are also two main types of digital lens, one being a high definition lens and the other being a low light lens. The low light lens offers a lower quality image but is not as portable as the high definition lens. For this reason, people often use a high definition webcam when they need extremely high-quality images. Typically, the two types of lenses will be found on the same camera system. The majority of digital camcorders have at least one of each type, although if you are on a tight budget you may be able to find one different model with only one lens.
Image sensors are another important feature when shopping for a good webcam. Image sensors are the part of your digital camera that detects movement and uses that motion to capture an image. This allows the person on the webcam to capture moving images without having to write a lot of code. The majority of cameras have an image sensor built right into them. However, you can purchase image sensors that plug into a PC for use in conjunction with the camera. Image sensors allow you to capture video without all of the complicated software that is often needed for webcams.
If you want to make the most of your webcam, then you should invest in some software that enables you to streamline the capabilities of your webcam. Streaming software will take all the hard work out of capturing and transferring videos. Most streaming software will work with all kinds of computers and capture video that is crystal clear and free of any errors. There are also software packages available for Macs that make it easy to stream videos to your webcam from Macs via USB. These software packages are especially useful if you want to share the videos with family or friends while traveling.
Many of the larger and more expensive webcams contain an image sensor chip within them. These image sensors are actually a part of the microprocessor that is contained inside the computer. When the chip begins to become corrupted, however, it may be necessary to replace the camera's image sensor chip.
