I apologize if this has been covered. I did a search but was unable to find any answers.

I want to know if anyone knows how far a drone can "see"? Especially the flying surveillance types. If there are no ideas from 4th edition I will take an answer from a previous edition.

Their Sensors have a range given by Signal as specified on p. 212 and 325.

I thought that was the range at which they can transmit. Not how far a camara on a drone can see.

It is really the only thing there is to go on.

Although I agree that using those numbers doesn't make much for many of the passive sensors.

The sensor may be able to pick up information from beyond it's Signal radius, but within that radius is the only range where the data's intelligible. You might lose resolution, be out of focus, or the sound could be too quiet to properly pick up.

For that matter, how far can a PC see with his eyes?
I assume the same rules would apply... if there were any
