Designed for industrial applications such as factory automation, logistic applications such as palletizing, package identification, measurement and handling. Safety and Precautions Follow these guidelines carefully before using your Helios camera. Definitions and Symbols Below is some warning, safety, and/or tips icons used in this document. -
Page 9: Laser Radiation
Laser Radiation The Helios camera emits infrared radiation that is invisible to the human eye. Helios has been tested to IEC / EN 60825-1: 2014 and classified as Class 1 (eye safe). The location and a sample of the laser safety classification label are shown in Figure 1. -

LUCID Vision Labs, Inc. to begin the RMA process. To achieve the specified accuracy of the Helios, the lens (see Figure 3) must be kept clean. Avoid touching the lens – fingerprints will significantly degrade performance. Dust should be blown off with a gentle clean air source (do not use aerosol cans) and or lens brush if necessary. -
Page 12: Installing The Camera Hardware
• Lucid Vision Labs recommends using qualified Ethernet cables from our web store. GPIO Cable The Helios camera is equipped with an 8-pin General Purpose Input/Output (GPIO) connector at the back. • The GPIO cable should be shielded for best performance. -
Page 13: Lens
Lens The M12 integrated lens is designed specifically for the Helios camera. The lens is 6mm in focal length and has a nominal field of view of 59° x 45° (nominal). To get the best performance, the lens needs to be perfectly clean. The slightest smudge or fingerprint on the glass vastly more inaccurate depth data. -
Page 14: Configuring The Camera And Host System
Configuring the Camera and Host System Installing the Ethernet Driver LUCID Vision Labs recommends updating to the latest version of your Ethernet adapter’s driver before connecting your camera. You may need to navigate to the manufacturer’s website to find the latest version of the driver. - Page 15 LUCID Helios Camera Technical Manual...

Bandwidth Management Jumbo Frames Lucid Vision Labs recommends enabling jumbo frames on your Ethernet adapter. A jumbo frame is an Ethernet frame that is larger than 1500 bytes. Most Ethernet adapters support jumbo frames; however, it is usually turned off by default. -
Page 18: User Sets, Streamables, And File Access
User Sets, Streamables, and File Access User Sets The Helios camera features two customizable user sets to load or save user-defined settings on the camera. Accessing the user set named Default will allow loading or saving of factory default settings. The camera will load the user set selected in UserSetDefault when powering up or when reset. - Page 19 User Sets, Streamables, and File Access functions do not load or save camera IP configuration settings.
