I am using a VIGI C540V (dual-lens) and I need to clarify the Auto Zoom functionality.

1. Where is the setting? Is Auto Zoom a standalone feature, or is it strictly part of the "Smart Tracking" menu?

2. Logic of operation: Does the camera use its 3x zoom automatically to enlarge a detected person/vehicle, or do I need to enable a specific "Auto Scale" option?

3. Dual-Lens switching: How does the Auto Zoom handle the transition between the long-focal and short-focal lenses during automatic tracking?

I want the camera to automatically zoom in on detected objects without manual intervention. Please guide me to the correct menu path.

Or does this model only support manual zoom via the app interface?
