Connecting VS125 to Vemcount

VS125 uses HTTP(S) push to send data directly to Vemcount. No gateway needed.
In the VS125 web interface, configure the data push URL to https://data.vemcount.com/ss/milesight.
Ensure outbound TCP 443 is open to data.vemcount.com.
Register the sensor in Vemcount: ⚙ Settings → Devices → + Add sensor → enter MAC address → Vendor: Milesight → submit.
For multi-device stitching across a wide entrance, configure the stitching group in the VS125 web interface first, then register each sensor separately in Vemcount and link them to the same zone.
