What is a Webcam? Definition, Uses, Types and More
A webcam is a video camera that streams a picture or video progressively to a PC or through an arranged PC. For example, the Internet.
Before entering fully into the establishment of the meaning webcam, it is necessary to know the etymological cause of the two words that shape it.
Camera, first of all, is a word that derives from Greek. Specifically, it comes from “kamára.”
Web, secondly, it is a term that comes from English “web,” which is synonymous with “mesh” or “network.”
The first webcams were small, and they captured images and video in low resolution, partly because the data transmission speed over the internet was regular, and not to shoot costs. And they were also effortless. A connection cable, a small focusing device, and support to place them at the right distance were the most common accessories.
At first, they emerged as an idea to allow the first videoconferences and video calls. As the intention was not to get high-resolution portraits.
They did not need a high optic, being the first VGA resolution formats (320×240), enough to see gestures and faces, but not many details.
Webcams spread worldwide following the advance of the internet. First, with the chats (the most veteran, you will remember the mythical IRC )and then with the video chats and video blogs.
Its use has also been extended in terms of security and leisure; there are currently millions of webcams that allow you to see what happens to live anywhere in the world, just having an internet connection.
The latter cameras do not need a computer to send the images to the network but are entirely autonomous.
Now we have cameras of all kinds, from high resolution, integrated with the monitor, with built-in microphones, even sticking to the wall, taking snapshots in burst or allowing talk and view at the same time regardless of the monitor.
The term camera has multiple applications. This time we are interested in its meaning as the device that allows you to take pictures. Web, meanwhile, is a concept that refers to a computer network.
The notion of webcam alludes to the camera type digital that connects to a computer (PC) to record and transmit images via the Internet.
This transmission is in private (between two or more processors) or public (by disseminating the photos on a website or a social network).
Web cameras constitute a technological evolution of the first cameras. The first cameras captured and recorded the photos in a chemical film.
Then, have to reveal roll or reel, a process that allowed to capture the images on paper. The photos, in short, were stored printed on material support.
The advances of computing, digital cameras emerge: unlike analog cameras, in this case, the photos save as digital data. So, we observe them on computers or televisions without printing them.
Web cameras, in this framework, are digital cameras specially designed to work connected to a computer with Internet access. It is used for videoconferences and live broadcasts. Surveillance tasks also use Web cameras.
Beyond these uses, webcams also allow you to register photos stored on the computer. In other words, user photographs, save the image, and then send it by email, for example.
In the same way, we must bear in mind that the existence of webcams has led to the emergence of a new idea of having sex.
It is cybersex and consists of two people making a video call to be able to get intimate. Rising conversations, being naked, and even masturbation are the fundamental pillars of this type of close “last generation” relationship.
