A webcam falls somewhere between a digital camera and a camcorder. Because of this, manufactures express image quality in a couple of different ways. Some manufactures will list a resolution of 1. 3 megapixels, while others will note a resolution of 1280 x 1024. These two measurements ultimately result in the same resolution. For your convenience, we have listed both types of resolution formats for each camera above so you can avoid the confusion and make easy comparisons.
As webcam capabilities have been added to instant messaging , text chat services such as AOL Instant Messenger , and VoIP services such as Skype , one-to-one live video communication over the Internet has now reached millions of mainstream PC users worldwide. Improved video quality has helped webcams encroach on traditional video conferencing systems. New features such as automatic lighting controls, real-time enhancements (retouching, wrinkle smoothing and vertical stretch), automatic face tracking and autofocus, assist users by providing substantial ease-of-use, further increasing the popularity of webcams.
A webcam is a video camera that feeds its image in real time to a computer or computer network . Unlike an IP camera (which uses a direct connection using ethernet or Wi-Fi ), a webcam is generally connected by a USB cable, FireWire cable, or similar cable.
Recently webcam privacy software has been introduced by such companies such as Stop Being Watched or Webcamlock. The software exposes access to a webcam and prompts the user to allow or deny access by showing what program is trying to access the webcam. Allowing the user to accept a trusted program the user recognizes or terminate the attempt immediately. Other companies on the market manufacture and sell sliding lens covers that allow users to retrofit the computer and close access to the camera lens.
One of the most telling specifications of any webcam is the frame rate. This measures how many frames the camera captures every second. When a camera records just one frame per second (fps), the video appears very choppy. You will see very little correspondence between the person’s mouth and the words he or she is speaking. A webcam with a frame rate of 30 fps, on the other hand, will produce video almost as fluid as a television broadcast.
Image quality is the most important aspect of a webcam. The best HD webcams offer 1920 x 1080 resolution and capture video at 30 FPS (frames per second). These two specs go hand in hand in creating full HD video, so even if a camera is capable of a 1080p resolution, a video capture speed of less than 30 FPS may not be fast enough to avoid choppy video. Check the listed video capture speed; if a 1080p camera captures video best at a lower resolution, you may as well just go with a lower resolution camera, which are usually less pricey.
Special software can use the video stream from a webcam to assist or enhance a user’s control of applications and games. Video features, including faces, shapes, models and colors can be observed and tracked to produce a corresponding form of control. For example, the position of a single light source can be tracked and used to emulate a mouse pointer, a head mounted light would enable hands-free computing and would greatly improve computer accessibility. This can be applied to games, providing additional control, improved interactivity and immersiveness. So currently, besides specific capture applications.
USB Webcam is probably most useful for Skype. This miniature camera packs next generation technology that records amazing quality audio and video in a average sized USB flash drive! This truly all-in-one product can record audio as well as video.
Portable. A combination of small physical size, 16GB SD card support, and portability ensure that it will fit any situation needed by professional law enforcement, private investigators, or even the casual user. No matter what your needs are, this camera will not disappoint you.
