Ganz GXi Series VCA Interface Manual V3.05.31.18 Measurement Units Allows the measurements units to be switched between Metric and Imperial formats. For more information, please refer to the Measurement Units topic. Metadata Format The metadata stream contains a complete description of every moving and stationary target, as well as additional diagnostic data to enable troubleshooting and optimum configuration. To save network bandwidth, the default metadata stream does not include a lot of the diagnostic data. The specific contents of the metadata stream can be configured with this control. The metadata stream can contain any selection of the following sub-streams: Event Contains information about events (alarms) raised due to objects triggering detection rules. Object Contains detailed information about each object tracked by the VCA engine including bounding box, object trail and object properties. Counting Contains the values of any counters that have been configured. Do not send empty metadata packets Check this option to save bandwidth consumed by the metadata. Metadata is only sent if the metadata is different from the previously transmitted metadata frame. Note that if any diagnostic metadata is enabled, metadata will always be sent, and this option has no effect. Blob Contains the blob-map data. This can be used to show the output of the object detection stage of the VCA algorithm. Enable this option for advanced performance analysis. For normal use it's recommended to keep this option disabled due to the increased bandwidth required by the transmission of the blob-map. Tamper Diagnostics Contains the tamper detection diagnostic data. This can be enabled to show the output of the tamper detection module. This can be useful when configuring the tamper detection filter. For normal use, this option should be disabled due to the increased bandwidth required by the transmission of the tamper detection debug data. Counting Line Diagnostics Contains the counting line diagnostic data. This can be enabled to show the internal operation of the counting line module. This can be useful when determining the optimum calibration width for a counting line. For more information about the counting line and the diagnostic data, refer to the Counting Line topic. Scene Change Diagnostics Contains the scene change diagnostic data. This can be enabled to show the internal operation of the scene change detection module. This can be useful when configuring the scene change detection thresholds (Learning Scene... trigger). For normal use, this option should be disabled due to the increased bandwidth required by the transmission of the scene change detection data. and topics for more information. 05-2018-A 108 | P a g e
