A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in Videotelephony, video telephony, live streaming and social media, and Closed-circuit television, security. Webcams can be Built-in function, built-in computer hardware or Peripheral, peripheral devices, and are commonly connected to a device using USB or Internet protocol suite, wireless protocol. Webcams have been used on the Internet as early as 1993, and the first widespread commercial one became available in 1994. Early webcam usage on the Internet was primarily limited to stationary shots streamed to web sites. In the late 1990s and early 2000s, instant messaging clients added support for webcams, increasing their popularity in video conferencing. Computer manufacturers later started integrating webcams into laptop hardware. In 2020, the COVID-19 pandemic caused a shortage of webcams due to the increased number of people Remote work, working from hom ...

QuickCam
QuickCam is a line of webcam video camera products originally produced by Connectix in 1994 and acquired by Logitech in 1998. Although its picture quality would today be considered primitive, it was the first widespread used webcam-like device. History The original QuickCam was developed by Connectix in 1994 for United States, US-wide commercial sale and was the first widely marketed webcam-like device, although its original advertising did not use the term "webcam" or refer to the World Wide Web, then in its infancy. Video conferencing via computers already existed at the time, and client-server based video conferencing software such as CU-SeeMe was gaining popularity. Eventually, it evolved from an RS-422 connector to a parallel connector then eventually to a USB, USB connection. The initial model was available only for the Apple Macintosh, connecting to it via the serial port. It produced 16 grayscale, shades of gray at a Display resolution, resolution of 320×240 pixels, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FogCam
FogCam is the longest-running webcam in the world, barring maintenance breaks and camera replacements. First set up in 1994 by two students, Jeff Schwartz and Dan Wong, it captures the scenery of the San Francisco State University and uploads it to a dedicated website. It was nearly shut down in 2019 as the creators said they faced difficulties in maintaining the webcam. Following public outcry, the university agreed to take over ownership and continue its maintenance. Operation The webcam is stationed at San Francisco State University, capturing student life and occasionally San Francisco's common fog. Every 20 seconds, a low-resolution (less than 320 by 200 pixels) image is taken and uploaded to its website, with the previous image being deleted. The camera has been moved several times partly due to pressures from the administration. Previous locations include a student health center with a view of the Tapia Drive, the Cafe Rosso line as a nod to the Trojan Room Coffee Pot ...

Videotelephony
Videotelephony (also known as videoconferencing or video calling) is the use of audio signal, audio and video for simultaneous two-way communication. Today, videotelephony is widespread. There are many terms to refer to videotelephony. ''Videophones'' are standalone devices for video calling (compare Telephone). In the present day, devices like smartphones and computers are capable of video calling, reducing the demand for separate videophones. ''Videoconferencing'' implies group communication.Mulbach et al, 1995. pg. 291. Videoconferencing is used in telepresence, whose goal is to create the illusion that remote participants are in the same room. The concept of videotelephony was conceived in the late 19th century, and versions were available to the public starting in the 1930s. Early demonstrations were installed at booths in post offices and shown at various world expositions. In 1970, AT&T launched the first commercial personal videotelephone system. In addition to videoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laptop
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a Clamshell design, clamshell form factor (design), form factor with a flat-panel computer screen, screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is in the lower part, under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers. Laptops are used in a variety of settings, such as at work (especially on business trips), in education, for PC game, playing games, Content creation, content creating, web browser, web browsing, for personal multimedia, and for general P ...

Closed-circuit Television
Closed-circuit television (CCTV), also known as video surveillance, is the use of closed-circuit television cameras to transmit a signal to a specific place on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point, point-to-multipoint (P2MP), or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring ( videotelephony is seldom called "CCTV"). The deployment of this technology has facilitated significant growth in state surveillance, a substantial rise in the methods of advanced social monitoring and control, and a host of crime prevention measures throughout the world. Though surveillance of the public using CCTV is common in many areas around the world, video surveillance has generated significant debate about balancing its us ...

Silicon Graphics Camera IMG 4205
Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid (sometimes considered a non-metal) and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Silicon is a significant element that is essential for several physiological and metabolic processes in plants. Silicon is widely regarded as the predominant semiconductor material due to its versatile applications in various electrical devices such as transistors, solar cells, integrated circuits, and others. These may be due to its significant band gap, expansive optical transmission range, extensive absorption spectrum, surface roughening, and effective anti-reflection coating. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to prepar ...

NTSC
NTSC (from National Television System Committee) is the first American standard for analog television, published and adopted in 1941. In 1961, it was assigned the designation System M. It is also known as EIA standard 170. In 1953, a second NTSC standard was adopted, which allowed for color television broadcast compatible with the existing stock of black-and-white receivers. It is one of three major color formats for analog television, the others being PAL and SECAM. ''NTSC color'' is usually associated with the System M; this combination is sometimes called NTSC II. The only other broadcast television system to use NTSC color was the System J. Brazil used System M with PAL color. Vietnam, Cambodia and Laos used System M with SECAM color – Vietnam later started using PAL in the early 1990s. The NTSC/System M standard was used in most of the Americas (except Argentina, Brazil, Paraguay, and Uruguay), Myanmar, South Korea, Taiwan, Philippines, Japan, and some Pacific Isl ...
