Automatic gain control. Amplifies existing video to help camera reproduce a
video signal at very low light levels.
Picture brightness adjusted automatically depending on lighting conditions.
Overcomes the problem of strong backlight which often causes the subject of
the picture to be cast into shadow.
Adaptive picture control. Automatically detects the condition of the recording
head and video cassette tape, then sets the optimum recording head current.
Available on all SVT time lapse VCRs.
Makes object outlines in the picture appear sharper. Ideal for situations where an
object merges into the scene with a similar shade.
Lens that allows for a wider viewing area with very little distortion.
Auto tracing white balance. Adjusts the white balance automatically in response
to varying light conditions.
Ideal for frequently changing light conditions and applications where the
operator needs to see objects as they appear to the eye. Effective operational
colour range is 2500 to 6000K.
Automatically adjusts the iris element as the light level changes.
Auto white balance. Automatically memorizes adjusted white balance values

Type of camera mount which measures 17.5 mm from the lens rear mounting
surface to the camera's CCD.
Type of camera mount which measures 12.5 mm from the lens rear mounting
surface to the camera's CCD. CS mount lenses can be used with C mount
cameras by adding a 5 mm spacer.
Lens that relies on DC power from the camera to control the iris.
Converts the analog signal from a CCD image sensor into a digital signal
through an internal A/D converter. The signal is then broken down into
luminance and chrominance components for processing, adjustment and feature
enhancement enabling many digital features such as backlight compensation.
Type of multiplexer allowing simultaneous live monitoring or playback as images
are being recorded.
HAD sensor with a nearly gap-less OCL (On-chip-lens) located over each pixel
on the CCD resulting in more than twice the sensitivity and 1/50 the smear
compared to the Hyper HAD CCD. Used in SSC-DC50AP/54AP/58AP cameras.
Original Sony recording method of the HSR-1P, which uses both a Hard Disk Drive
and DV tape. Images are first recorded to HDD, then transferred to DV tape.
HAD sensor with an OCL (On-chip-lens) located over each pixel on the CCD which
helps increase sensitivity and reduce smear. Used in most Sony security cameras.
