Here is my take on it, from several POVs.
Actual X-Ray vision: Nope, what he sees in the video is what he gets.
Actual Telescopic vision: Depends on the quality of the media. If it is a high resolution media, he could possibly see what is on the other side if there was a key hole, or he could see what is behind the camera if there was a mirror. If he is looking at your typical security camera footage, (which, honestly, is often REALLY crappy) I don't think so.
Psionic vision(covers X-Ray, Telescopic, Microscopic): same as Telescopic above with the following cavet. It might be possible for his ability to extrapolate details that vision alone just might not pick up.
