8.2.1 AZTECH™ CODEC Settings

The AZTECH™ CODEC is the default CODEC for most systems. To switch the recording CODEC to AZTECH, select the AZTECH option
from the CODEC drop-down menu.

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.
