Cameras have been introduced quite a while ago and through constant development, some good technology is available to people in the modern days. Even video cameras are available which can be used to record videos. With all these improvements being brought in the market, there is a lot of equipment that you could try out. But while integrating something with your computer, you would need to make sure that you would not make it overly complicated. That is why simple devices are specially designed that would help you to offer live video streams or even record them on need. That is where webcams come in.
The webcams are video cameras that would feed or stream image in real time through a computer network. The video stream that is captured by the camera can be saved, viewed or sent to other networks via the Internet or other modes. They can even be emailed as an attachment. These videos sent to the remote location can be saved or viewed there. A webcam is very much unlike an IP camera which would connect with the help of Ethernet or Wi-Fi. The webcam would be generally connected using the USB cable or a similar cable or can also be built into computer hardware like laptops.
The PC webcams, as it is referred in the original sense as a video camera connected to the web continuously, can be used to provide a view for someone who is visiting the webpage over the Internet. Some of these webcams can thus find good use as traffic cameras as they can be expensive and rugged professional cameras. Webcams have a low manufacturing cost but would offer quite a lot of flexibility. In spite of the low cost of these cameras, the resolution and quality of the video offered by them are to quite impressive.
The most popular use of PC webcams that can be found today is the establishment of video links that would permit computers to act like video conference stations or videophones. There are other popular uses as well that include computer vision, security surveillance, video broadcasting and other social videos. Most of these webcams would be able to capture the arterial pulse rate with a good accuracy. They can also be used for monitoring childcare centers, shops, homes, offices and other private areas for security and general activity. The most important function probably is the video calling that has become very common in the modern days.
The advent of the webcams was done in 1991 and was used in the Cambridge University and was switched off in 2001. The first commercial webcams were sold in 1994 and soon became available at a very good price. Over the years, the increasing popularity of the Internet has made its use more and more common to the point where in modern days most laptops would feature a webcam and are brought along with most desktops.
