I suppose, if Flint's M-4 is sensitive to the behavior of his guests, then it wouldn't be unreasonable for his surveillance system to be likewise. The problem here and with the other examples is that the footage used for the viewers doesn't seem to have been shot as surveillance camera footage; it seems that it was all shot as regular movie/episode footage and then used for surveillance camera footage. See a show such as Person of Interest for an example where footage used as surveillance footage is shot as surveillance camera footage. In that case, there are considerations made for the surveillance camera POV. These subspace scan/LIDAR/etc. explanations are vaguely interesting, but in the end they're handwaves made after the fact to paper over a production issue.
