General Safety Notices

	Powering the Camera The camera may not work, may be damaged, or may exhibit unintended behavior if powered outside of the specified power range. When using the GPIO, the supplied power must be within the stated voltage range. See the Power section for further information.
	Operating Temperature The camera may not work, may be damaged, or may exhibit unintended behavior if operated outside of the specified temperature range. See the Temperature section for further information.
	Caution, use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Do not open the camera housing. Do not contact the laser apertures with any objects. Damage to the laser modules could produce hazardous radiation levels.
	Electrostatic Discharge Ensure proper precautions are implement to prevent damage from an electrostatic discharge.
	Image Quality Dust or fingerprints on the sensor may result in a loss of image quality. Work in a clean and dust-free environment. Use only compressed ionized air or an optics cleaner to clean the surface of the sensor window. Refer to the Maintenance section for details.

Laser Radiation

The HTW003S camera emits infrared radiation that is invisible to the human eye. HTW003S 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 the figure below. The location and a sample of the product label are shown.

Emission is produced with four VCSEL (lasers) with integrated diffusers that illuminate the field of view. The laser apertures are shown below.

The diffusers are integral to the eye safety classification and must not be damaged or removed. The emission characteristics are as follows: Wavelength: 850nm +/- 10nm Divergence (Full Width at Half Maximum): 60°×45° Maximum average power: 2.2mW (through IEC/EN 60825-1:2014 limiting aperture)
