    Enabling Face Detection by Recorder

    2. Select the Enable button.
    3. Select Rule to adjust the minimum and maximum face detection size. The minimum and maximum value will depend on how far away the camera is from the faces that are getting captured. In most cases, this setting does not require adjustment.

    Enabling Face Recognition by Recorder

    Used in conjunction with Face Detection, Face Recognition can detect people that have been added to a “Face Library”, and trigger events off this. Generally, this function is used to trigger an action on the recorder when a person in a predetermined face list is seen.

    Additional Setup

    Schedule IVS Recording

    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.

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