=== Zones ===The default zone is Active and so will be red, Inclusive zones are orange, exclusive zones are purple, preclusive zones are blue and inactive zones are white.* Active - trigger on any event within selection* Inclusive - triggered only if another zone has an event also* Exclusive - triggered only if other zone not triggered* Preclusive -* Inactive - no alarms will be triggered=== Blobs AlarmedPixels FilteredPixels ===* Alarmed Pixels - This image shows all pixels in the zone that are considered to be alarmed as white pixels and all other pixels as black. * Filtered Pixels - This is as stage one except that all pixels removed by the filters are now black. The white pixels represent the pixels that are candidates to generate an event. * Raw Blobs - This image contains all alarmed pixels from stage 2 but aggrageted into blobs. Each blob will have a different greyscale value (between 1 and 254) so they can be difficult to spot with the naked eye but using a colour picker or photoshop will make it easier to see what blob is what. * Filtered Blobs - This image is as stage 3 but under (or over) sized blobs have been removed. This is the final step before determining if an event has occurred, just prior to the number of blobs being counted. Thus this image forms the basis for determining whether an event is generated and outlining on alarmed images is done from the blobs in this image.
