    @Optical98 Do you have the source of those images? This forum downsizes them

    There was a release of permits for their repairs https://surfside.one/public-records-search/

    The roofing repair permit was released titled "8777 COLLINS AVE PERMIT # 21-211-APPLICATION" from https://surfside.one/public-records-search/ I'm not sure if it's interesting or not, it cost them...

    @pellucidar I don't think it's much evidence on it's own, that basement is below sea level (at high tide at least), and with all the known water leaks there's plenty of explanation to how water got there. Could there still be differential settlement sure, but I don't think the pool of water...

    @clouditguy I'm pretty sure the actual ethernet packets sent over wifi are all of the same size? Regardless the audio/video are part of the same packets on that level. I do know that Layer4-7 will not retry in the context of video/audio, because generally the codecs/encoding are designed to...

    @jbourne8 Oh yeah I forgot security video is usually low frame rate. Also I meant the external video, I don't think it's possible to sync the external video to the internal ring video to under 1 frame because we don't know exactly when they stopped/started (We don't know if it had already...

    @jbourne8 half a second delay is massive for humans, I think most people can detect audio delay from video under 150ms without too much issue. I don't work with audio too much though, I mostly work with stuff where latency must be under 16ms and something like 50ms is considered a long time to...

    @clouditguy I think the camera likely was battery powered (or could be), but it's router, and the router's cabling to whatever it's peered to, and potentially whatever router and cables are peered to that if it's in the same building were likely destroyed rather quickly - especially it's...

    I found a longer more complete 911 call log, listening through it now to see if there's anything useful but I sadly doubt it (everyday non-engineers + panic and fear) but probably worth checking anyway. https://www.youtube.com/watch?v=v2zRuxNjG2I

    Just found another video I haven't seen mentioned, it's from a video of a Hurricane Wilma in 2005. https://www.youtube.com/watch?v=X4BwnI0VyPM Around the 3:30 mark there appears to be a shot of the pool/patio deck and it looks rather torn up. Can any structure/civil engi tell if this is...

    New video of the balconies was just released showing more wear on the balconies. https://www.youtube.com/watch?v=Ltw77weRymA...

    Does anyone know the model number or specs for this camera? Especially the focal length of this camera/lens, we can try to calculate/motion track the room _maybe_.

    Indeed there is a NOTAM (FDC 1/3702) for "hazards", up to 3000ft centered on the collapse. https://tfr.faa.gov/save_pages/detail_1_3702.html

    Thanks! I guess that rules out compression then!

    I've been looking at the video more. I'm fairly confident the floor is higher on the left side then the right at the end of the video, I think by roughly 10deg as this is both the angle of the wall next to the refrigerator and the angle of the dust. This is confusing to me though because if...

    Those chips/dust in that ring video seems to me to be way more then just some type of dust falling - something was either ripping/tearing, or being compressed so much that chips were being ejected (I lean towards this one). Either way, it seems likely the chips are being ejected from their...

    I'm not sure if it was mentioned yet but I wanted to add this because I just found it. It's their minutes report from their October 2020 meeting. It looks like they did exploratory demolitions and there's some photos in there. This appears to be where the "curious results" is from. Direct link...
