Webcams are small digital cameras used to capture images or video and transmit them back to their host device, usually via USB cable or other analog connection. Webcams have various uses including surveillance of public spaces as well as remote conferencing sessions.

There is an array of webcams on the market today, each boasting different capabilities. Some more expensive models provide features like whiteboard modes that automatically frame and remove hand gestures or objects to produce an undistorted shot; whereas PTZ cameras from Obsbot and Insta360 allow them to track you or other subjects physically without your having to manually reposition them yourself.

Webcams can be used for various applications, including surveillance, conferencing and robotics. Banking sectors often utilize webcams for monitoring all sections of a bank before sending all recorded data back to its main server for further investigation. Furthermore, they are frequently deployed remotely in remote areas to keep an eye on roads and parking lots.

One of the key aspects to keep in mind when selecting a webcam is its microphone quality. Most webcams feature omnidirectional mics that pick up noise from various directions; others may offer noise cancellation capabilities that reduce ambient background noise but sometimes cause voice processing to occur – however this feature might cause your voice to sound processed and may not always work well; you can always supplement a webcam microphone with an external one for improved results.
