67 [A] Auto Dome

A camera with full integration, high speed, pan/tilt/zoom function built into a protective dome housing allowing full and continuous 360 degree coverage of the scene.

66 [A] Auto Iris

The lens iris opening is automatically adjusted to allow the correct illumination of the camera sensor.

65 [A] Auto focus

Autofocus refers to a camera lens' ability to adjust its configuration in order to focus properly on a subject regardless of whether it is near or far from the camera. Autofocus lenses generally provide vastly superior image quality than do their fixed focus cousins since they do not have to rely on their depth of field.

64 [A] Address

Each unit has a numerical address in the control system in which it is located. This allows the appropriate unit to be operated.

63 [A] AAC (Advanced Alarm Control)

A flexible and sophisticated alarm management subsystem that allows rules to be created which define that input(s) activate one or more output(s). In its most basic form, a rule could define which inputs should activate which outputs. In a more complex form, a rule can be programmed to take specific keyboard command (pre-existing or not) and perform a dome function, or any combination of the above.

62 [C] CVBS (Color, Video, Blanking and Sync)

NTSC/PAL analog video output. RCA, BNC, or terminal block outputs are provided in DirectIP cameras.

You can use this to adjust the camera angle and focus during the installation.

61 [D] Dymanic range

The ratio of the measurable bright and dark intensity or the ability to show how much of a wide range of signals: dark to light.
The higher it is, you can discern/resolve more details of similar.

60 [S] SNR (Signal to Noise Ratio)

SNR means the ratio of the amplitude of a analog or digital data signal to the amplitude of noise. Typically SNR is expressed in decibels (dB).


59 [D] DPC (Defect Pixel Correction)

Corrects defective dead or hot pixel.

58 [L] LENC (Lens Correction)

Corrects the lens shading and/or barrel distortion.
