    The Boost-function enables an increase in the refresh rate (frame rate) of different streams according to previously defined events. This can reduce network utilisation as well as the memory usage during continuous recording, as a high refresh rate is only needed for evaluation of incidents when there is an event (e.g. movement or triggering by alarm contact).

    Configuration of the boost function

    Configuration of the Boost function is based on the Event In/Event Out principle. In the Event In section a trigger is designed for the Boost function. The following events can be used as a trigger:

    • On Boot – camera start (when the camera is turned on)
    • Manual Trigger – manual activation be a person (e.g. by software button in the web interface)
    • Motion – motion detection
    • Network Loss – interruption of the network connection
    • AIHM – recording failed or successful formatting of the disk
    • Time Trigger – scheduled event

    An example of the configuration for motion detection is described below. The purpose is: When the camera does not detect motion it transmits the stream with only a low frame rate (e.g. 2 fps). As soon as motion is detected, the camera raises the frame rate (e.g. to 15 fps). After the event has finished the camera reduces the frame rate (back to 2 fps).

    1. In the camera web interface at Event -> Event in -> Motion you configure the camera motion detection as described in the operating manual.
    2. At Event -> Event out -> Boost you configure the Boost function.
      There is the option of configuring each stream separately to give a high degree of flexibility. Enable the function by putting a tick against Enable Boost. In the Normal Condition column the frame rate for normal operation (without an event) is defined. In the "Boost Condition" column the target frame rate during an event is set. Bitrate control "CBR" furthermore gives the option of manually configuring the bitrate.

    3. At the Event Map menu item you link the trigger to the action. Select motion detection as Event In (trigger). As Event Out (action) select the Boost function. Confirm the selection with OK. Finished!

    Tip: A multiple selection is possible for Event Out. This means that a trigger can start multiple actions at the same time (e.g. when motion is detected the refresh rate is raised, local recording on the SD is started card and a notification is sent by e-mail). To do this, you simply place a tick before the corresponding actions.
