Webcams are used for online communication, videoconferencing and a range of other applications. They are commonly built into laptops but can be standalone units that attach to the monitor of a desktop computer. In addition, many online courses and classes use a webcam to allow students to experience the teacher’s body language and non-verbal communications, allowing them to connect more closely with the material.
During the COVID-19 pandemic, the number of remote workers increased and as a result, webcams became more widely used for online meetings and other virtual communication. The latest webcams offer high-definition video, improved microphones and other advanced features to improve the quality of online interactions.
The most common use of an online webcam is videoconferencing, which allows people to communicate with one another remotely using video and audio. This is especially useful for businesses that want to reduce costs by avoiding travel expenses or students who are not able to attend lectures in person.
Most online webcams are compatible with Windows, Mac and Linux computers and usually connect via a USB interface. However, it’s important to check the system requirements of a specific model to make sure that it works with your computer.
When shopping for a webcam, the most important specification is its field of view (FOV). The wider this is, the better it will be for videoconferencing or other uses that require a large area to be captured. Most of the best webcams have FOVs that are at least 90 degrees wide, while some can be as wide as 270 degrees. Some also feature zoom capabilities, which can be useful for capturing an area close up without losing quality. online webcams
