Logic 3 V5.00 - Manual (Page 54)

Resets CODEC settings to their default values for the selected camera.
Picture Quality Adjusts picture quality of the recorded images. Higher quality video will occupy more
space on disk. You can use the slider or the text box to change the values.
Noise Reduction Adjustment used to reduce video noise on grainy video.
2.1.2.1 AZTECH CODEC Settings
The AZTECH CODEC is the default codec used for recording video footage. To change to the AZTECH CODEC,
select “AZTECH” from the CODEC drop-down box.
Space Saving
Mode (AZTECH)
Enabled
Enables advanced compression technology to decrease the file size of recorded
footage.
Caution: This is a CPU intensive setting.
Sensitivity
Threshold used by the codec to identify areas of change between frames. The higher
the sensitivity, the smaller a change is encoded.
Noise Adaptive
Noise threshold used by the comparison algorithm when determining whether a block
contains a change. When this value is increased, more noise is allowed in the block
without triggering change for that block. This feature does not decrease noise in an
image.
Detect Using
GrayScale/Color
Determines whether grayscale or color will be used to detect changes. Use color when
it is necessary to detect a change in color such as a warning light. Color detection
requires more processing power, therefore grayscale is recommended for both color
and black and white cameras unless necessary.
