Understanding webcams along with functions and how webcams work

Webcam allows a computer user to record themselves in realtime, and then spread it to the public through the help of the internet network. Enough with a small device that is usually installed at the top of the monitor, a computer user can broadcast his image to the public via the internet network with the help of software or applications, such as Skype. This webcam is more or less like a digital camera. It's just that, in contrast to digital cameras in general, this one camera is designed to be able to process photos that are relatively complex and can be easily uploaded directly to sites (usually social media sites) that have internet. In the following article, we will explain in more detail about the definition of webcam, webcam functions and how the webcam works itself.

Understanding webcams



Wireless webcam

Webcam aka 'web camera' is a device in the form of a digital camera that is connected to a computer or laptop. Like a camera in general, a webcam can send pictures live from anywhere in the world with the help of the internet. At the beginning of its appearance, this webcam is still an expensive item. But, along with technological advancements, there are already many laptops whose screens have been equipped with webcams. For computers, rarely is there a default webcam, the computer owner must buy it separately separately.

There are many types of webcams sold on the market. Some of them can be connected to a computer using a USB port, but there are also some types of wireless. In general, the webcam is equipped with a number of features such as:

Microphone
Ability to be shifted and adjusted to its position (as desired by the user)
Built-in sensor that can detect movement in front of it
Indicator lights which when lit means the camera is active
The use of webcams has become widespread lately because the need for remote communication using software is increasingly in demand, for example Skype. No one thought that communicating using a webcam would be as popular as it is today. History records that the first webcam was created named Xcoffee.


Xcoffe, the first webcam in the world

This camera was made in 1991 by Quentin Stafford-Fraser and Paul Jardetzky, which then could only be connected to the Internet in 1993 with the help of Daniel Gordon and Martyn Johnson. In his trial period, this camera was used to monitor a coffee shop outside the Trojan Room at the University of Cambridge. This is so that people do not need to go to a coffee shop when the coffee shop in the shop is empty.

Webcam function
It is undeniable that the existence of this webcam has many functions, including in terms of:

1. Communicate
The existence of a webcam allows computer users to communicate directly. Not only that, we can also easily see the face of the other person. Currently there are many software that provide such features, some of which are Skype, Google Hangout, Viber and so on. Communication by using a webcam is very helpful in connecting two or more people who are located far from each other or when we want to contact our family who are abroad.

2. Distance learning
You can easily study with someone even if you are separated by a long distance, for example you are in Indonesia, the person you are talking to is in America. With this webcam, the distance problem is no longer a problem. Through this webcam, students or students can ask their teacher if there are questions or things about the school subject. Webcams also allow training or training through the Internet. In fact, a number of parties offer webinars or seminars through the web.

3. Remote conference
There are times when a company uses a webcam to hold a remote conference. Those in remote locations are not a problem and will not miss the conference. In addition, with this video conference via webcam, between managers and employees do not have to be in the same location if there is a meeting or meeting.

How a Webcam Works



Webcam is a kind of compact camera that can be mounted to a computer or laptop to broadcast video in real-time or live. Similar to a digital camera in general, a webcam works by capturing light through a small lens on the front with the help of a microscopic light detector installed on the receiver's microchip, which is generally a Charge-Couple Device (CCD) or CMOS image sensor.

Even the images obtained can be directly digitally processed and disseminated via the internet. It's just that, unlike a digital camera, a webcam is not equipped with a memory chip or flash memory card. Webcam is designed to not need to "save" images because the main function is only recording and sending images that are obtained directly. That is why one type of webcam uses a USB cable on the back. This USB cable supplies electricity to the webcam from the computer and retrieves digital information captured by the webcam sensor to be forwarded to the computer.

Each webcam has different features and capabilities. Likewise with the purchase price. Some webcams have only been able to capture still images every 30 seconds, there is also a video streaming feature with a speed of 30 images per second. Webcams are easily found and available in almost all computer stores and large electronic retailers.
