Do you still have "Save AI analysis details" checked ? If so, you can view the DAT file from a successful Alert video by holding Ctrl while you double click the video. That tells you exactly what BI5 and CPAI are doing.
The BI5 Log is best viewed by setting it to a text file, as it tries to amalgamate things in the general view. It only creates one file a month, so I leave it on desktop, and manually dump them in a folder later. This Log file will show line by line what BI5 was doing.
Together these will give you the info you need.
If you have no custom model specified for a camera, then you are using the default model "Objects". General settings/ AI would have "Default Object detection" checked. The DAT file will show you are using "Objects". I would get it working with this before you go much further.
The models will only detect things that are pre-trained in that model. The default model covers everything from broccoli to kitchen sinks, which quite simply are of little use for cctv surveillance. MikeLuds custom models cut out a lot of these items, and are hence faster. If you add something to "To confirm" that doesn't exist in the model - or even spell it incorrectly - it will barf and won't tell you. I can't find the list of "labels" in the default model, but MikeLuds
models are on Github, and have these labels:
IPcam-combined Labels: - person, bicycle, car, motorcycle, bus, truck, bird, cat, dog, horse, sheep, cow, bear, deer, rabbit, raccoon, fox, skunk, squirrel, pig
IPcam-general Labels (includes dark models images): - person, vehicle
IPcam-animal Labels: - bird, cat, dog, horse, sheep, cow, bear, deer, rabbit, raccoon, fox, skunk, squirrel, pig
IPcam-dark Labels: - Bicycle, Bus, Car, Cat, Dog, Motorcycle, Person
license-plate Labels: - DayPlate, NightPlate
Plate Label: - Plate
So now you would uncheck the default model in General settings/AI, and for the camera add the model required. Have a look
here at the CPAI website for basic details.
PS> You have a gap between labels in your "To confirm" list between a comma and car. So easy to do. This also broke the system with previous versions of BI5 and CPAI so may still be true. Delete the gap and see if it starts detecting - then let us know if that still breaks it !
