The Strathclyde Police site link does not say they will be used ONLY in demanding conditions. I would certainly NOT be flying in these areas in such conditions.
It says they will be used to search BEFORE the arrival of other aircraft, AND can be used in poor visibility and weather.
What concerns me is that there has been no mention that any attempt will be made to notify pilots who might be in the area, nor of what lookout will be kept for aircraft. The manufacturers site mentions the controller having a helmet display.
The picture shows a mainly dark object, which will camoflage well against the cliffs, ground, and lochs.
The onboard camera is not looking for aircraft. Similar size camoflaged birds have two excellent eyes, hearing, and great manoueverability, to avoid collisions.
