Example use

Example 1

.A macro -command to initiate VMD-triggered to start recording to the Archive from the archive when the motion detector generates an event on any camera within the Default Axxon-domain (see Configuring start conditions).

Example 2

. All video cameras from the Default Axxon Domain -domain are set to continuously record video at the specified fps by dropping frames with decimation to the archive (see Configuring recording to an archive). When you have a motion detection event, you need to switch to full fps recording. Configure the following macro to do so:
Image RemovedA macro records to the archive by events from the motion detector at full frame rate.
