A webcam is a device designed to capture an image in real time and transmit it to the Internet. Most webcams have the functionality of digital cameras and camcorders.
Most of the webcams are connected to a stationary computer or laptop. There are mobile computers that have a built-in webcam. Typically, these devices work with special applications. These can be universal messengers, such as Skype, or special utilities designed to work only with certain camera models.
Most "home" webcams are designed to broadcast images to the network or to capture specific moments. There are more complex analogs, endowed with motion sensors and other additional devices. These camera models can be used in security systems.
For the first time the use of a webcam was recorded in 1991. Modern webcams are used for communication between people in cases where it becomes necessary to transmit video in real time. Some cameras are installed to monitor specific objects. This allows you to examine the state of the desired area at the right time using remote access to the webcam.
Currently, you can find models of webcams that have their own motion sensors and other sensors. Such devices are actively used in game consoles, allowing you to control the gameplay without resorting to a joystick or other manipulators.
The most interesting type of webcam is the network camera. It is capable of functioning as a stand-alone web server. The capabilities of such a device include automatic focusing on a specific object, having its own IP address, controlling a webcam using a remote computer. In most cases, you can not only turn the IP camera on or off, but even change its position and operating parameters.
