The poor video quality makes it artificially difficult to see. I can barely see the faces of even the people in the front.

This is one of test for red cross lifeguard training. However in real life it is much better to spot drowning victims than video.

Yeah having a perspective that is so different from the lifeguard does make it really hard.

This is likely perspective you have while also browsing HN on your phone. That's the whole point - it's really hard to spot one unless you are looking for him, have training and are positioned properly.

Being distracted by your phone and not seeing a drowning child is different from paying close attention to a low-res 2D image and not seeing a drowning child. You can't fully train for one by practising the other.
