1. Introduction
1.1. Series Introduction
The VENUS USB3 Vision camera is DAHENG IMAGING's innovative board level industrial digital camera,
featuring outstanding performance, powerful features, and outstanding price/performance ratio. The
VENUS USB3.0 Vision cameras are include split monocular USB3.0 Interface cameras, split binocular
USB3.0 Interface cameras, all-in-one USB3.0 Interface cameras and all-in-one FPC Interface cameras.
The cameras are available in a variety of resolutions and frame rates, and are available with CMOS
sensors from leading chip manufacturers, which is easy to install and use.
The VENUS USB3 Vision digital camera transmits image data through the USB3.0 data interface. Thanks
to the locking screw connectors, the VENUS USB3 Vision cameras can secure the reliability of cameras
deployed in harsh industrial environments (split USB3.0 Interface cameras, all-in-one USB3.0 Interface
board level cameras and all-in-one FPC Interface cameras without locking screw connectors). Featuring
high reliability and high price/performance ratio, the VENUS USB3 Vision cameras are especially suitable
for machine vision applications such as industrial inspection, medical, scientific research, education,
security and so on.
1.2. Naming Rules
Details of the VENUS USB3 Vision series camera is given in the general specifications below. Each
camera model name is determined by its sensor's maximum resolution, maximum frame rate at maximum
resolution, the color/monochrome type of the sensor, etc.
Figure 1-1 Naming rules
1.3. Standards
The camera follows the USB3 Vision1.0 standard, and its development interface GalaxySDK is
implemented based on the GEN<i>CAM standard.
