中Protocol documents for face terminals (VF10X / VF106 series): HTTP protocol, MQTT protocol, serial communication protocol and the authorized passcode mechanism - pick the version that fits your integration.
This page collects all communication protocol documents for Vguang face terminals (VF10X / VF106 series) - download the version that fits your integration method.
VF10X HTTP Protocol v1.0.22
For VF10X series face terminals integrating with a platform via HTTP callbacks: the terminal acts as a client reporting recognition results, device status and heartbeats to the server, and receives platform commands such as person sync and remote door opening. v1.0.22 is the latest version.
VF10X MQTT Protocol v1.0.13
For IoT bidirectional communication through an MQTT broker: the terminal subscribes to command topics and publishes to data topics, with QoS 1 message guarantee and last-will messages. v1.0.13 is the current version.
VF10X Communication Protocol v1.0.1
Covers control commands, result reporting and parameter configuration over serial (RS232 / RS485 / TTL), for embedded secondary development and turnstile / access controller integration.
VF106 MQTT Protocol v1.0.0
MQTT protocol dedicated to the VF106 model. It differs from the VF10X MQTT protocol in topic structure and message body - VF106 devices must use this protocol.
Authorized Passcode Mechanism Guide v1.0
Explains the generation rules, validity period management and door opening flow of dynamic authorized passcodes, for visitor temporary authorization and offline door access scenarios.
Selection notes
For new projects use the latest HTTP protocol (v1.0.22); for IoT low-power scenarios use MQTT; for embedded serial integration use the communication protocol; refer to the PDF for exact command formats and checksums.

FAQ
Which integration method does each protocol fit?
The HTTP protocol is for terminals reporting data and receiving commands via HTTP callbacks to a platform; the MQTT protocol is for IoT bidirectional communication through an MQTT broker; the communication protocol is for secondary development over serial (RS232/RS485/TTL); the authorized passcode mechanism guide covers dynamic passcode door access scenarios.
What is the difference between VF10X and VF106?
VF10X is a series-wide model covering multiple face terminal hardware configurations; VF106 is a specific model with its own MQTT protocol. For new projects we recommend the latest VF10X HTTP protocol v1.0.22.
