First use Internet Explorer as this camera more than most will not hold or show all settings in other browsers. You may not see all the settings in Chrome.
You will not see anything in the settings called AutoTrack.
You need to set up a preset.
Then you need to set-up the Smart Plan with Deep IVS for the presets you want to track.
Then select the object filters you want.
Then go to Deep IVS Rules Config page and you should see Track Time under alarm and Tracking Target size slider.
When setting up IVS rules, I strongly recommend you use intrusion box with appears and crosses instead of tripwire. And less is more. One IVS rule.
Leave min size as 0,0
Make sure that Motion Detection and Smart Motion Detection are turned off.
I repeat, make sure Motion Detection and Smart Motion Detection are turned off LOL.
