It was probably less a coincidence and more of SOP. The guards probably have to do rounds at set times (every hour, for example) and then post up somewhere between those times and most likely fall asleep, or do a crossword puzzle or whatever to pass the time. As for electronic failure, I would say it's probably common as well. Just search for "Prison conditions in the united states" or "deterioration of prisons". Our prions are overcrowded and under funded. These things are usually reported in regards to the terrible conditions for prisoners (heating constantly failing, mice/bug infestations, leaking roofs, etc), but this also applies to equipment used by guards. We are talking about facilities running old facilities and equipment with minimum maintenance. Even if the camera's didn't fail (I am not up to date on the story, but I assume they both did?), I would be surprised if the quality of the footage was usable (or if it was even recorded).
