Avoiding EMI and ESD ProblemsThe cameras are frequently installed in industrial environments. These environments often includedevices that generate electromagnetic interference (EMI) and they are prone to electrostaticdischarge (ESD). Excessive EMI and ESD can cause problems with your camera such as falsetriggering or can cause the camera to suddenly stop capturing images. EMI and ESD can also havea negative impact on the quality of the image data transmitted by the camera.To avoid problems with EMI and ESD, you should follow these general guidelines:? Always use high quality shielded cables. The use of high quality cables is one of the bestdefenses against EMI and ESD.? Avoid to coil camera cables. If the cables are too long, use a meandering path

Avoid placing camera cables parallel to wires carrying high-current, switching voltages such aswires supplying stepper motors or electrical devices that employ switching technology. Placingcamera cables near to these types of devices may cause problems with the camera.? Attempt to connect all grounds to a single point, e.g use a single power outlet for the entiresystem and connect all grounds to the single outlet. This will help to avoid large ground loops.(Large ground loops can be a primary cause of EMI problems.)? Use a line filter on the main power supply.? Install the camera and camera cables as far as possible from devices generating sparks. Ifnecessary, use additional shielding.? Decrease the risk of electrostatic disch
