GenTL: a generic transport layer interface, between software drivers and libraries, that can be used
for device enumeration, attribute control, and image acquisition.
SFNC: common naming convention for camera features, which promotes interoperability between
products from different manufactures.

1.5. Guideline for Avoiding EMI/ESD
You should consider the EMI (Electro Magnetic Interference) and ESD (Electro-Static discharge) problem
in the process of using the camera, to guarantee the camera to work in a relatively good electromagnetic
environment. The main measures are as follows:
1) USB cable certificated by USB-IF is recommended.
2) Connect I/O cable shield conductor to ground. Try to use camera cables that are the correct length.
Avoid coiling camera cables. If the cables are too long, use a meandering path rather than coiling the
cables.
3) Keep your cameras away from equipment with high voltage, or high current (as motor, inverter, relay,
etc.). If necessary, use additional shielding protection.
4) ESD (electro-static discharge) may damage cameras permanently, so use suitable clothing (cotton)
and shoes, and touch the metal to discharge the electro-static before operating cameras.
