GigE Vision Interface Overview: 100m Transmission and PoE Support
GigE Vision is an interface standard that transmits image and control data from industrial cameras to host systems via standard Gigabit Ethernet, requiring no dedicated frame grabber hardware .
Key Technical Facts:
Transmission Distance: Up to 100 meters per cable segment using standard Cat5e or Cat6 cabling
Theoretical Throughput: 1,000 Mbit/s (125 MB/s) with typical sustained rates of 90–110 MB/s per camera
Power over Ethernet: Allows camera power delivery through the same cable
Network Infrastructure: Standard RJ45 connectors, switches, and Ethernet hardware
Protocol Architecture:
GigE Vision operates through two sub-protocols :
GVCP (Control Protocol): Manages device discovery, IP configuration, and camera parameter access
GVSP (Data Streaming Protocol): Handles image and measurement data transfer
The standard is maintained by the Association for Advancing Automation (A3). Version 2.0 (2011) added multi-camera synchronization and enhanced bandwidth support for higher-resolution sensors .
