Setup
2 - 26 ADPRO FastTrace, Issue 5
2.3.3.3.5 Use Activity Detection
The ADPRO FastTrace can be setup to respond to changes that occur within the field of view of a camera. This feature
is used to trigger an alarm if activity is detected by a certain camera in an area not normally expected to have activity.
To help configure the Activity Detection feature, the sensitivity to movement and the amount of time that movement
occurs, can be programmed.
2.3.3.3.6 Sensitivity
Options: Very Low, Low, Medium, High, Very High
Default: Medium
Choose the most appropriate sensitivity level to suit the camera lighting and scene conditions. The Low setting is used
when large portions of the viewing area may be affected by movement. Use the Higher setting when the light is well
controlled (indoors) and detection of smaller or slower targets is required.
2.3.3.3.7 Hold Time
Options: None, 2, 5, 10, 30, 60
Default: None
When there is a requirement that two (related) alarm inputs must be active before an alarm is activated (known a double
knock alarm activation), the Hold Time option sets the time ‘window’ for the second alarm input to occur.
If the second alarm input is not activated within the Hold Time period, no alarm event will be generated. Choose the
value most suited to the alarm activation requirement.
2.3.3.3.8 Activity Detection Area
Use the Configure button to set the Activity Detection Area used by each configured camera. The detection area is
displayed as a ‘grid’ over the video image, showing exactly where activity detection will happen. More than one
activity detection area can be used. An Activity Detection Area is made up of a number of ‘detection zones’, with each
zone representing a screen area of 16 x 16 PIXELs.
CAUTION
If recording on event, a zero hold time is recommended to ensure that all activity is recorded.
Non zero hold times may result in only one event trigger for the total duration of activity when
observing a busy scene (when new activity detections occur within the hold time the timer
restarts and only one event is generated.
