    Tripwire & IVS Setup

    The below instructions are for setting up a Tripwire, however the same process is followed for Intrusion & Abandoned/Missing Object. 

    1. From the Main Menu, select AI > Parameters > Smart Plan.
    2. Select a channel with IVS functionality. Click the icon then Apply to enable the IVS.
    3. Select the IVS tab. Select the same camera channel, then click Add button at the bottom. This will create a new IVS setting (Tripwire by default).
    4. Click the Draw button to open the Draw screen.
    5. Left-click on the screen to start drawing the Tripwire line. Left-click again to finish the line (optionally, you can add additional corners to the line by continuing to leftclick). Right-click to finish placing the line.
    6. When using select functions such as Tripwire, In the top left window, you can alter the Direction that the line must be passed from to activate the event, as indicated by the arrow going across the line (A to B, B to A, or both ways). 
    7. (NOTE: This step requires an AI camera.) AI Recognition enables Perimeter Protection when using Tripwire or Intrusion functions. This will recognise and differentiate between people, vehicles and other moving objects. Turn the option On to enable this function.
    8. Click OK to finish. 
    9. Click the Enable box to turn on the IVS rule.
    10. Click Apply to save changes. If done correctly, you will see the Tripwire in live view

    Configuring Recording Schedules

    You can define the recorded footage schedule in the Record menu, and the recorded image snapshot schedule in the Snapshot menu. By default, cameras are set to non-stop Regular recording (24 hours a day, 7 days a week). Motion detection recording is not set by default. Schedules can be set in hourly periods for individual days for each camera, with colour-coded options for:

    • Regular/General for all regular recording.
    • MD/Motion for recording on motion detection.
    • Alarm for recording on triggering an integrated alarm.
    • MD & Alarm for simultaneous alarm/motion detection recording.
    • IVS for recording on triggering IVS (Intelligent Video Surveillance) such as a virtual tripwire.
    • POS for point of sale transactions.

    Info

    Note: When using standalone IP cameras, IVS and MD/Motion are both labelled as Event.

    We recommend adding MD & Alarm & IVS to all channels to accompany your regular recording.
