While it is technically feasible to use a standard HMDI cable to connect the Tobii Pro Glasses 2 Head Unit with the Recording Unit, it is not recommended, as the original cable provided by Tobii is made very flexible and unobtrusive to make sure the participant can move freely.
The IR light from the eye-tracking illuminators is invisible to the eye, but sometimes visible to digital cameras. Digital cameras often use infrared blockers, but cheaper digital cameras and camera phones have less effective filters and can 'see' intense near-infrared light, appearing as a bright purple-white color.
The exact WLAN range of the Tobii Pro Glasses 2 depends on the hardware you use and the environment you are using it in.

The Tobii Pro Glasses 2 system is primarily designed for use in dry indoor environments. Depending on the level of sunlight Glasses 2 will function in outdoor environments as well. Make sure that the Glasses are not exposed to direct sunlight since that might affect eye tracking results negatively. Further make sure that the Glasses are protected from water or moisture since that might harm the unit. For more info please read chapter 1.1.11 of the Tobii Pro Glasses 2 Manual.
