"HawkEye II is intended to see expansive areas wtih resolutions that allow users to detect movements of people and vehicles. It does not provide the ability to detect gender, ethnicity, age, hair color, nor can it be used for facial recognition. This is an inherent limit to Wide Area Motion Imagery. If cameras get better - and they will - the same rseolution limits will remain in place, the change will be in the size of the coverage area."
At least the company behind this seems to be ethical.
