The devices are easily portable and you can quickly disconnect one from your computer and connect it to another computer including a desktop or laptop model. You can also attach a USB webcam to a USB hub and extend its distance from your computer and allow a wider field of view. This is ideal for when you need to capture a large panel of people during a video conference or you want the camera to capture your entire office during a meeting or other event. Just bear in mind you may lose quality in this instance.
Attachments and Quality
Most webcams come with a stand or hooks for placing the device on a flat surface or to attach it to a shelf, monitor, or another area. USB webcams also contain larger, adjustable lenses that result in better overall picture quality than built-in laptop webcams. A lot of webcams now, even smaller ones offer an Autofocus feature and almost all have Zoom functions. Smaller cameras utilise a Digital Zoom feature whereas more premium options have both Digital and Optical Zoom features giving you an amazing image making them ideal for video calls and streaming.
