In addition to use for personal videoconferencing, it was quickly realised that World Wide Web users enjoyed viewing images from cameras set up by others elsewhere in the world. While the term "webcam" refers to the technology generally, the first part of the term ("web-") is often replaced with a word describing what can be viewed with the camera, such as a netcam or streetcam. Educators can use webcams to take their students on virtual field trips.

Today there are millions of webcams that provide views into homes, offices and other buildings as well as providing panoramic views of cities (Metrocams) and the countryside. Webcams are used to monitor traffic with TraffiCams, the weather with WeatherCams and even volcanoes with VolcanoCams. Webcam aggregators allow viewers to search for specific webcams based on geography or other criteria.

WebCam Software

Webcams connected to PCs can act as web-accessible cameras with certain software. Usually this kind of software works with most webcams, since the software auto-detects the peripheral. Many different programs are available, free, open source, and proprietary.

Webcam software can be configured in many ways. Some software[specify] come with motion detection ability and time lapse capture options or both. Captures can be short videos in predefined length or still images. Thus, the software can essentially turn the web cam into a security camera. Many businesses and home owners can effectively use a simple webcam device to create their own security system with only a webcam and one of these types of software applications.

The captured files can be saved locally, uploaded to an internet server (via FTP or HTTP) (from which they can be made accessible to anyone over the web), or privately e-mailed to the user per predefined rules. Options for image size and quality, overlaying logos, and time stamping images are usually available. File names can be sequential numbers or current time. Some software allow automatic erasure of old files when not needed.

Some software can remotely control certain brands of cameras, allowing rotation and tilting.
