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 sen-
sitivity, the smaller a change is encoded.
Noise Adaptive
Adjusts the noise threshold used by the comparison algorithm when determining whether a block con-
tains 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.
