It is probably common practice for Gov agencies to watch video from very small cameras. The rf signals from the cameras are pretty weak, almost always in the milliwatt range. The low power is to increase battery life. The signal is picked up by the large NRO satellites in orbit 22,000 miles above the equator. Even at a range of 22,000 miles the weak transmitters put a huge signal into the 300+ foot diameter dish antennas on those NRO birds. To give you an idea of the signal gathering power of these big NRO satellites they could pick up the weak signals from the Voyager spacecraft that has left the solar system...if you pointed them in that direction.
If the seal team was using these types of cameras (and I can’t imagine they were not) then each camera would be on a slightly different frequency and would be a separate live feed. So for all of them to go dark at the same time the only explanation would be that the Osama complex was constructed with a copper mesh liner in the walls and ceilings. This is routinely done where it is important for there to be no rf leakage.
Zero rf leakage form a home that size is a dead giveaway that something is going on in there. It’s like a wanted man wearing a sack on his head so the cops won’t recognize him.
Three floors worth of ordinary construction materials would not in any way hamper the reception of the cameras rf feed.
Only the tiniest fraction of the rf would need to escape to give a good signal into the satellite.

Wouldn’t a relay, perhaps to to the chopper equipped with a satellite transmitter be the more likely scenario? A 300 ft aperture is pretty large but video takes bandwidth and I would be surprised if you could close that link at bandwidths that would give decent video quality.
