SECTION 4: DVR SOFTWARE USAGE
• SS – Spatial Sensitivity (on selected models). Use SS to set the sensitivity for detecting the size of
one object (the number of the grids) on the screen. A small value represents a higher sensitivity for
motion detection.
NOTE
The SS number represents the least number of blocks in which motion is detected for the
system to trigger recording. For example, if SS is 05 and motion is detected in 5 or more
blocks, a record trigger will occur. The default SS value is 03.
• TS – Time of Sensitivity (on selected models). TS represents how long an object stays in the
detection area before triggering a recording. Depending on the model, one of the following options
is used:
— Select a value. A small value represents a high sensitivity for motion detection.
— Select either HIGH or NORMAL.
• RE – Reference (on selected models). RE sets a reference for detection. With the default value of
10, the DVR will compare 10 continuous images at one time using the parameters LS, SS, and TS.
• ALARM (selected models). Select N.C. (normally closed) or N.O. (normally open) to match the alarm
switch design, or select OFF (default).
