Showing boxes or not is option you can enable/disable. usually called Dynamic analysis.
Yes Car should be in blue square upon detection, red if triggeting an event and another reactangle red with only edges will show tracking target.
First fix the detection, Check if the detection and triggering works, tracking wont work if first step is not done.
Only camera i have on new webUI are ANPR ones, so i cant really help cause dont have PTZ options on it. But Logic is the same for any firmware, itsjust that options are probably set elsewhere on UI
Another question is....what about if i literally set the tracking on the view right outside the house and set it to the highest sensitivity then anything that comes into view...it will follow?? (or am i asking too much of it!)
If you haveAuto tracking 3.0 , you cant do that

Thats the downside
