Some computers are available with a built-in webcam, and you can also connect to external webcams for computers that they don't already have. A webcam is a digital camera that is connected to a computer to retrieve video and audio. While a webcam can be useful to help people see each other when they are communicating, you might find the disadvantages of webcams being an unwanted burden.
Hidden Live Webcams
Live Webcams enable your computer to broadcast video over the internet so that other people see and hear you and your environment. A disadvantage of a webcam is that a person can install it on a computer and then transmit what the camera sees as a series of still images or streaming video without the perceived people being aware of, such as a hidden camera set up in a company, school or government building . A viewer can see where you are, what you do, and how long you stay in the location.
Keeping Up Appearances
A webcam user can start a video chat application and then make contact with someone else who also has a webcam. Webcam chat software usually makes you see how you appear on the other person's computer so that you can position yourself and make sure the lighting conditions are sufficient for you to be seen. However, a disadvantage to using a webcam is that the person you speak to can see you, which can force you to spend extra time and effort tracking your appearance if you prefer to stay casual or even unseen. In contrast, every time you pick up the phone and have a conversation with someone, you don't have to worry about making that your hair, clothing or makeup are showable.
When you engage in a real face-to-face conversation with someone, you are usually able to tell like other people in the same room, and whether they are close enough to eavesdropping. A drawback to using a webcam is that the person you were talking to could be using a computer in a public area where other people can easily see and hear while remaining out of your eye. If you forget that your webcam is turned on, someone can see you doing something embarrassing while you're not aware.
If you have a webcam installed on your computer and your friends, family and colleagues are aware that you have it, a disadvantage is that they will be able to meet the expectations that you have available and willing to conduct video chats over the internet even if you don't want to develop . For example, if you are in a video call with someone, they can always try to communicate with you via video in the future, even if you prefer to use the phone, email or instant messaging again. Just as problematic is the prospect that the people you want to see in person will now prefer to just see you through the webcam out of ease, avoiding actual contact.
