VMDA detection are detection tools due to triggering of which some actions can be performed in the system.

Important!

Up to Intellect version 4.10.2, VMDA detection tools trigger only if recording to the archive is performed (permanently or by alarm of the Motion detection tool). Intellect since version 4.10.3, recording is not an obligatory condition for VMDA detection tool to trigger.

For instance, when the detection tool with corresponding settings triggers, the alarm on camera is generated and recording to the archive starts. Thus VMDA detection tools allow recording to the archive and, therefore, the recording of object trajectories, not steadily, but in the required situations.

If it is necessary to initiate a camera alarm when the VMDA detection tool is triggered, select the Generate alarm on camera check box.

Detections arming and disarming is performed using macros or scripts which are to be created manually (detailed information about macros see in the Creating and using macros section). The initial state of detection is defined by Generate alarm on camera checkbox – detection armed if the checkbox is set, otherwise – disarmed. 

The table below describes the cases and reactions on detection tool triggering (e.g. on line crossing or motion in the area).

 Detection tool is armedDetection tool is disarmed
Generate alarm on camera check box is setAlarm on camera + alarm on detection toolnothing happens
Generate alarm on camera check box is not setAlarm on detection toolnothing happens


Note.

The Disappearance in the area  detection tool is triggered immediately after an object in the area disappears. By default, the alarm is reset 15 seconds after the alarm is triggered. To change the length of time after which an alarm is reset, edit the DisappearedAlarmDuration registry key in the HKEY_LOCAL_MACHINE\SOFTWARE\ITV\INTELLECT\Video section for 32-bit systems (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ITV\INTELLECT\Video for 64-bit systems).

To create a VMDA detector, do the following:

  1. Go to the Hardware tab in the System settings dialog box.
  2. Select the Tracker object in the objects tree of the Hardware tab.
  3. Create the VMDA detection object on the base of the Tracker object. The settings panel for the created object appears on the right of the Hardware tab.

Note.

 Video from the camera on the baase of which the VMDA detection object is created is displayed in the Video field.

The VMDA detection is now created. Information only about the objects that triggered detector action is recorded to the VMDA metadata storage.

Attention!

Creating VMDA detection on IP cameras, do not forget about information in the Requirements for IP devices section.
