Preventing Operational Faults due to ESD
Nano camera installations which do not protect against ESD (electrostatic
discharge) may exhibit operational faults. Problems such as random packet
loss, random camera resets, and random loss of Ethernet connections, may all
be solved by proper ESD management.
The Nano camera when used with a simple power supply and Ethernet cable is
not properly connected to earth ground and therefore is susceptible to ESD
caused problems. An Ethernet cable has no ground connection and a power
supply’s 0 volt return line is not necessarily connected to earth ground.
Teledyne DALSA has performed ESD testing on Nano cameras using an 8 kilovolt ESD generator
without any indication of operational faults. The two following methods, either individually or
together will prevent ESD problems.
•
Method 1: Use a shielded/grounded power supply that connects ground to pin-10 of the I/O
connector. The Nano case is now properly connected to earth ground and can withstand
ESD of 8 kilovolts, as tested by Teledyne DALSA.
•
Method 2: When using Power over Ethernet (PoE), Teledyne DALSA strongly recommends
using a shielded Ethernet cable to provide a ground connection from the controlling
computer/power supply, to the Genie Nano. PoE requires a powered computer NIC, or a
powered Ethernet switch, or an Ethernet power injector.
•
Method 3: Mount the camera on a metallic platform with a good connection to earth ground.
