The International (SI) unit of measurement of the intensity of light. It is equal to the illumination of a surface one meter away from a single candle.

A method of more accurate and sophisticated video processing.

Each AutoDome has a numerical address in the control system in which it is located. This allows the appropriate dome to be operated. The address may be set locally using the Bilinx Configuration Tool for Imaging Devices (CTFID) or remotely using the Fast Address function (see Fast Address).

Also known as ALPR (Automatic License Plate Reading)

The size of the opening in the iris controlling the amount of light reaching the sensor. The larger the F-Stop number the less light.

The lens continuously adjusts to the correct focus automatically for the sharpest picture.

The lens iris opening is automatically adjusted to allow the correct illumination of the camera sensor. With direct drive or DC Iris lenses the camera controls the size of the aperture. Video iris lenses have the control circuits built into the lens.

The electronics that regulate the gain or amplification of the signal.
