⚙️ Yes, the Hikvision DS-2CD3656G2T-IZS supports smart event-triggered auto-zoom using its motorized varifocal lens and AcuSense technology.

Here’s how to configure auto-zoom on event (like tripwire or intrusion detection):

✅ Step-by-step setup (via Hikvision NVR or web interface):
Login to the camera via browser or NVR

Go to Configuration > Event > Smart Event

Enable Line Crossing Detection or Intrusion Detection

Under Linkage Method, select:

“PTZ Linkage” (if available)

Set it to trigger Zoom to Preset or Zoom Ratio

Use the motorized lens controls to define focal lengths and set Preset Positions

Save the rule and test the perimeter detection

⚠️ Note: This model features motorized zoom but not PT (Pan-Tilt), so it zooms in/out within the field of view, not by rotating.

📌 For Indian users deploying perimeter surveillance (e.g., factories, farms, housing societies), this feature provides auto-tracking-like behavior by digitally zooming on breach events.
