An Introduction to WebCams

Today’s Eio post is on webcams.

A webcam is a miniature camera that records video onto a computer. They are considered input devices, meaning they are external to a computer but connect, either directly or wirelessly, via USB, ethernet, or Wi-Fi connections.

Webcams are known for their low-cost and flexibility, making their uses diverse. With newer technology, web cams can be placed in covert places around one’s office or room, to be used as a spy-camera, or for video survellience.


Webcams have a plethora of uses. In many modern laptops and computer monitors, webcams come built-in so you do not have to buy an external webcam. But built-in webcams often do not have the same flexibility or range of movement as do external webcams, which can be moved around and pivoted in various directions and degrees.

Videocalling and Videoconferencing

Live video communication over the internet, usually over services such as Skype of AOL instant messenger, is one of the most useful benefits of webcams. Companies can have one-on-one video conference calls, or conference calls that include entire board rooms full of people.

Video Security

Webcams can also have built-in technology to record when it detects sound or movement, and thus be used as video surviellance cameras.

Eio carries a large catalog of webcams. When choosing which external webcam is right for your needs, there are various things to think about:

  • Effective Pixels, such as 0.3M, 1.3M, 2.0M, or 3M.
  • Image Sensors
  • Maximum Image Resolution
  • Supplier to choose from
