This is actually something that can be pretty safely ruled out. Spy satellites like this are placed at very low orbits, which allows them to get very high resolution images. At these low orbits, the satellites are moving incredibly fast relative to the ground. They're circling the earth in 1 to 2 hours. This is advantageous since the same satellite can be used to observe different areas and with minimal maneuvering can make passes over a much wider area than they could see in a single orbit, and even follow slow moving targets like fleets of ships or army columns, but it also means that they are only observing any particular place on earth for a very brief interval with substantial periods of time in between. While you could see the timelapse of say a building being constructed, they can't make high resolution videos of things that take more than a few seconds and less than several hours. To get continuous imaging in a particular spot, you need to utilize a very different orbit that will take the satellite much further away from Earth, which ruins the resolution of any imaging. While the exact resolution of a given satellite is classified, the laws of physics put upper bounds on how good an image they can possibly get. Any satellite that could track and record a specific individual for an extended period of time would be way too large to launch.
