These cameras do not require a video capture card because they work using a digital signal which can be saved directly to a computer. The signal is compressed 5:1, but DVD quality can be achieved with more compression (MPEG-2 is standard for DVD-video, and has a higher compression ratio than 5:1, with a slightly lower video quality than 5:1 at best, and is adjustable for the amount of space to ...
A one megapixel camera with the onboard video analytics was able to detect a human at a distance of about 350' and an angle of view of about 30 degrees in non-ideal conditions. Rules could be set for a "virtual fence" or intrusion into a pre-defined area.
Computer-controlled cameras can identify, track, and categorize objects in their field of view. [150] Video content analysis, also referred to as video analytics, is the capability of automatically analyzing video to detect and determine temporal events not based on a single image but rather on object classification.

In studio cameras, the camera electronics shrank, and CCD imagers replaced the pickup tubes. The thick multi-core cables connecting the camera head to the CCU were replaced in the late seventies with triax connections, a slender video cable that carried multiple video signals, intercom audio, and control circuits, and could be run for a mile or ...
The USB video device class (also USB video class or UVC) is a USB device class that describes devices capable of streaming video like webcams, digital camcorders, transcoders, analog video converters and still-image cameras.
Camera-tube focus coils, by themselves, have essentially parallel lines of force, very different from the localized semi-toroidal magnetic field geometry inside a TV receiver CRT focus coil. The latter is essentially a magnetic lens ; it focuses the "crossover" (between the CRT's cathode and G1 electrode, where the electrons pinch together and ...
Wireless communication with PC input and output devices, the most common being the mouse, keyboard and printer. Transfer of files, contact details, calendar appointments, and reminders between devices with OBEX [a] and sharing directories via FTP.

A typical case is the running of an app on a smart TV such as Netflix, but reproduction of audio is handled by the other equipment. [41] Without ARC, the audio output from the TV must be routed by another cable, typically TOSLink or RCA, into the speaker system. [52] HDMI Ethernet Channel (HEC)
