Automatic gain control. Amplifies existing video to help camera reproduce a video
signal at very low light levels.
Analog backlight compensation (BLC)
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.
Aspherical type lens
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 color 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.
DC servo auto iris lens
Lens that relies on DC power from the camera to control the iris.
DSP (Digital signal processing)
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.
Exwave HAD Technology
Technology 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 technology. Used in SSC-DC50A/54A/330/334, SPT-M320/M324
Original Sony recording method of the HSR-1/2, which uses both a Hard Disk Drive
and DV tape. Images are first recorded to HDD, then transferred to DV tape.
Hyper HAD Technology
Technology 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.
LP recording mode which allows three times as many frames/s to be recorded in
24 H mode. (SVT-168E/40E/LC300/DL224/S480ES only)
Reality Regenerotor (R2)
Improvement over conventional sharpness which results in very little noise and
more accurate picture reproduction during playback.
The amount of light falling on a scene measured in lux.
Type of multiplexer which allows the user to choose between live monitoring,
recording or playback.
Digital circuit within the camera providing automatic backlight compensation by
automatically adjusting iris and gain. See DSP also.
Vertical streaks above and below a brightly lit object or light source when observed
on the monitor. Vertical lines on the screen are caused by the leakage of
unwanted light onto the vertical shift register of the CCD.
Used in multi-camera installations where automatic switching is employed and
allows roll-free switching from camera to camera.
Sony CRT which allows for high resolution and the best possible picture
reproduction. The completely flat, straight vertical surface of the Trinitron CRT
provides very low purity imperfection.
Video, sync and power transmitted over a single coaxial cable.
Powerful automatic gain control function. Increases range of video gain compared
to conventional AGC resulting in greater sensitivity.
Video servo auto iris lens
Lens that relies on video input to control the iris opening. When the video level is
high, the lens iris closes. When the video level is low, it opens.
White balance mode recommended for outdoor daytime shooting
