Camera Link is a serial communication protocol standard [1] designed for camera interface applications based on the National Semiconductor interface Channel-link. It was designed for the purpose of standardizing scientific and industrial video products including cameras, cables and frame grabbers .
IndigoVision relabels cameras manufactured by Avigilon, also a Motorola Solutions company. [9] The company, which formerly relabeled cameras manufactured by Dahua Technology , told IPVM that the change was made due to NDAA and supply-chain concerns.
The cameras in a multiple-camera setup are controlled by a device known as a camera control unit (CCU), to which they are connected via a triax, fibre optic or the almost obsolete multicore cable. The CCU, along with genlock and other equipment, is installed in the central apparatus room (CAR) of the television studio.

Wireless monitoring of the alarm system protects against a burglar cutting cables or from failures of an internet provider. This setup is commonly referred to as fully wireless.
The essential matrix can be seen as a precursor to the fundamental matrix, .Both matrices can be used for establishing constraints between matching image points, but the fundamental matrix can only be used in relation to calibrated cameras since the inner camera parameters (matrices and ′) must be known in order to achieve the normalization.
