Fixed cameras' resolution typically does not exceed 20 megapixels. The main feature of a PTZ is its remote directional and optical zoom capability. With multi-sensor cameras, wider areas can be monitored. Industrial video surveillance systems use network video recorders to support IP cameras. These devices are responsible for the recording ...

The new video camera tube developed by Lubszynski, Rodda and McGee in 1934 was dubbed "the super-Emitron". This tube is a combination of the image dissector and the Emitron. It has an efficient photocathode that transforms the scene light into an electron image; the latter is then accelerated towards a target specially prepared for the emission ...
Digital video is an electronic representation of moving visual images in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession, usually at 24, 25, 30, or 60 frames per second ...
Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.

Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impact the user's perception of the system.
