Calibir GXM640 IR Camera User's Manual
Technical Specifications
131
Power over Ethernet (PoE) Support
The Calibir GXM640 requires a PoE Class 0 or Class 1 (or greater) power source
for the network if not using a separate external power source connected to pins 1
& 2 of the camera’s I/O Connector.
To use PoE, the camera network setup requires a powered computer NIC
supporting PoE, or a PoE capable Ethernet switch, or an Ethernet power injector.
Important: Connect power via the I/O connector or PoE, but not both.
Although Calibir GXM640 has protection, differences in ground levels may
cause operational issues or electrical faults.
When using PoE, the camera’s I/O pin 1 (Camera Power – Ground) and pin
2 (Camera Power- Power) must not be connected.
If both supplies are connected and active, the Calibir GXM640 will use the
I/O power supply connector. But as stated, ground differences may cause
camera faults or failure.
