1. Introduction
1.1. Series Introduction
The MARS GigE series (MARS-G-P) camera is DAHENG IMAGING's mature area scan industrial digital
camera, featuring outstanding performance, powerful features, outstanding price/performance ratio. The
camera supports Power over Ethernet (PoE, IEEE802.3af compliant), which is easy to install and use. The
MARS-G-P series cameras are available in a variety of resolutions and frame rates, and are available with
CMOS sensors from leading chip manufacturers.
The MARS-G-Pseries digital camera transmits image data through the GigE data interface. Thanks to the
locking screw connectors, the MARS series cameras can secure the reliability of cameras deployed in
harsh industrial environments. Featuring high reliability and high price/performance ratio, the MARS series
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 MARS GigE series (MARS-G-P) camera are 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.
