Space Saving
Mode (AZTECH)
Enabled
Enables advanced compression technology to decrease the file size of recorded footage.
Note: This is a CPU intensive setting.
Sensitivity
Adjusts the threshold used by the CODEC to identify areas of change between frames. The higher
the sensitivity, the smaller a change is encoded.
Noise Adaptive
Adjusts the 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.
Note: Color detection is a CPU intensive setting.
Use B Frame
Uses bi-directional frames to decrease the file size of recorded footage.
Note: This is a CPU intensive setting.
Adjusts the picture quality of the recorded video. Higher quality video will occupy more space on the
video storage drive. The arrows, the text box, or the slide bar can be used to change the value.
How Picture Quality Can Affect Total Disk Usage:
Picture Quality
Noise Reduction Adjusts the level of video noise for grainy video.
