77 [C] CMOS (Complementary Metal-Oxide Semiconductor)

CMOS traditionally consumes little power. Implementing a sensor in CMOS yields a low-power sensor. CMOS chip can be fabricated on just about any standard silicon production line, so they tend to be extremely inexpensive compared to CCD sensors.

76 [C] CCD (Charged Coupled Device)

CCDs use a special manufacturing process to create the ability to transport charge across the chip without distortion. This process leads to HQ sensors in terms of fidelity and light sensitivity. CCDs use a process that consumes lots of power. CCD consumes a much as 100times more power than an equivalent CMOS sensor. CCD sensors have been mass produced for a longer period of time, so they are more mature. They tend to have higher quality and more pixels.

75 [B] BLC (Back Light Compensation)

In images where a bright light source is behind the subject of interest, the subject would normally appear in silhouette. BLC allows the camera to adjust the exposure of the entire image to properly expose the subject in the foreground. However, WDR is a more effective alternative to BLC because it handles multiple exposure zones to give both the highlight and low light areas a proper exposure.

74 [B] Baud rate

Unit of measure for the speed of data transmission.

73 [A] Auto Track

A technology that integrates motion detection into the camera allowing tracking an object and zooming in to optimize size and its perspective.

72 [A] Auto Scaling

As the camera zooms in to increase the size of objects on the monitor screen, the pan and tilt speeds are reduced so that the relative speed on the screen remains constant.

71 [A] Auto Playback

A feature records the sequence of movements of the camera’s PTZ for later playback allowing a set pattern to be repeated automatically.

70 [A] Auto Pivot

As the camera tilts through the vertical position, the camera rotates to maintain the correct orientation of the image.

69 [A] Auto Black

A techniques that boost video signal level to produce a full amplitude video signal, even if its scene contrast is less than full range (glare, fog, mist, etc).

68 [A] Auto Pan

The camera pans moves continuously between right and left with limit settings.
