Avoiding EMI and ESD Problems

BCON uses low voltage differential signaling (LVDS) to transmit image data from the camera to the
image processing unit. LVDS is a differential signal transmission standard with two parallel traces
for each signal. The voltage change on one trace is always the exact inverse of the other. Their
electric fields cancel each other out, resulting in a reduced emission of electromagnetic radiation.
Due to the close proximity of the parallel traces, electric fields can't induce a significant differential
voltage. This makes LVDS resistant against such interference. However, this does not apply to
electromagnetic interference (EMI), unless the parallel traces are twisted, which is usually not the
case for PCB traces and also not for flexible flat cables (FFCs).
Therefore, dart BCON cameras are prone to EMI and also electrostatic discharge (ESD). EMI and
ESD can cause problems with your camera such as false triggering or can cause the camera to
suddenly stop capturing images. EMI and ESD can also have a 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:
Install the camera as far as possible from devices generating sparks or strong electromagnetic

fields.
Keep the cable away from unshielded electric motors, transformers, and unshielded coils.

Decrease the risk of electrostatic discharge (ESD) by taking the following measures:

Use conductive materials at the point of installation (e.g., floor, workplace).

Use suitable clothing (cotton) and shoes.

Control the humidity in your environment. Low humidity can cause ESD problems.
