Preventing Operational Faults due to ESD
Genie 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 Genie 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 Genie 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 power supply. The Genie 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 TS. 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.
