Figures 2 and 3 show interconnection diagrams for 3930
•
Figure 2 shows a setup of the camera system with PoE-enabled switch.
•
Figure 3 shows a setup of the camera system using the PoE injector with non-PoE switch.
NOTE: If your PC has a GigE network interface, you can bypass the switch and plug the camera system
RJ45 cable directly into the GigE port on your computer.
These diagrams represent typical installations. Each installation site will have its own unique requirements.
Power over Ethernet (PoE)
The 3930
camera system is compliant with the IEEE 802.3at standard. Power to the camera system is
HD
supplied through the network cabling. Two types of PoE implementations are specified by the standard:
•
Endspan PoE: Power is applied directly by the switch to the camera system. This method requires
the deployment of a PoE-enabled switch.
•
Midspan PoE: Power is supplied by an injector placed between an existing non-PoE switch and the
camera system.
PoE injectors can be ordered from CohuHD. PoE injector is supplied with the HD15 option. Please refer to
the CohuHD web page in the 3930
selected for use with 3930
•
Be compatible with the IEEE 802.3at standard. For information on PoE injectors, refer to the web-
site:
