Webcam allows computer users to record themselves in real-time and spread it to the public through the contribution of an internet connection.
Just a cute device that is usually installed on the top of the monitor, a computer user can broadcast his picture to the public via an internet connection with the help of software or programs, such as Skype.
This webcam is more or less like a digital camera. However, in contrast to digital cameras in general, this camera is planned to process photos that are relatively complex and can be easily uploaded directly to several sites (generally social media sites) that have the internet. In the article below, we will explain in more detail the understanding of the webcam, the role of the webcam, and the workings of the webcam.
A webcam aka 'web camera' is a device in the form of a digital camera that is connected to a computer or netbook. Like cameras in general, a webcam can send live images from anywhere in the world with the help of the internet.
Initially its existence, this webcam is still an expensive item. However, along with the development of technology, there have been many netbooks whose monitors have been equipped with webcams. For computers, there are rarely standard ones equipped with webcams, computer owners must first purchase them separately.
There are several types of webcams sold in the market. Some of them can be connected to a computer using a USB port, but some are wireless. In general, webcams are equipped with several features, for example:
- Strength to be shifted and equalized (as the user wishes)
- A built-in sensor that detects movement in front of it
- The sign light that glows means that the camera is active
The use of webcams has become very popular lately because the need for remote communication using software is becoming more and more popular, for example, Skype. No one expected if talking using a webcam would be as popular as it is today. History writes that the first webcam was named Xcoffee.
This camera was created in 1991 by Quentin Stafford-Fraser and Paul Jardetzky which was then only connected to the Internet in 1993 with the contribution of Daniel Gordon and Martyn Johnson. During his experimental period, the camera was used to monitor a coffee shop outside the Trojan Room at the University of Cambridge. This is intended so that people do not need to go to a coffee shop when the coffee stock in the shop is empty.
The presence of a webcam allows computer users to talk directly. Not only that, we can easily see the face of our speaking enemy.
Now there are many software that provides such features, one of which is Skype, Google Hangout, Viber, and others. Communication using this webcam really helps connect 2 or more people who are located equally far away or when we want to contact our family who is abroad.
You can easily study with someone even if you are separated by a long distance, for example, you are in Indonesia, your speaking enemy is in America. Because there is this webcam, the problem of distance is no longer a problem.
Through this webcam, some students or students can ask their teacher if there are questions or things crammed around school subjects. Webcam allows training or training via the Internet. In fact, some factions offer online seminar services or seminars through the site.
There are times when companies use webcams to hold remote meetings. Those who are in remote locations are also not a problem and do not miss the ongoing meeting. In addition, because there is a video meeting via this webcam, managers and employees do not have to be in the same location when a meeting or meeting is being held.
Webcam Working Steps
The images obtained can also be directly processed digitally and disseminated via the internet. However, unlike a digital camera, a webcam is not equipped with a memory card or flash memory card. Webcams are designed to not need to "save" images because their main function is to record and transmit the images they receive directly.
That's the cause, one of which is a type of webcam that uses a USB cable on the back. This USB cable supplies power to the webcam from the computer and retrieves digital information secured by the webcam sensor to transmit to the computer.
Each webcam has different features and strengths. The same goes for the purchase price. Some webcams can only capture still images every 30 seconds, some provide video streaming features at a speed of 30 images per second. Webcams are easy to find and are available in almost all computer stores and major electronics retailers.
