  • Genuine question - why would the house numbers be different?

    In urban areas, I’m used to house numbers starting at 1 at one end of the street, then incrementing as you go along. Usually odds and evens are on the opposite sides of the street. So the house on the corner will be 1, the house opposite it will be 2, the house next to 1 will be 3, and so on.

    Each street starts the numbers again.

    Is this not the case where you are?







  • Have a look at the Bananapi options, especially the R3. (Or the R2, it’s a bit more mature)

    It’s a very capable single board computer with onboard managed switch, including SFP cages. If you want, you can buy antennas and utilise the wifi 6, or get a dedicated access point.

    PFsense, openwrt, et al all have images. I think some people also run the mikrotik OS on it. It’s powerful enough to run as a hypervisor so you can chop and change between all of these if you want.

    It gets bonus points for accepting 5G modems for failover.


  • There’s a lot more to it than that, but yes. At least in my world, RAID isn’t really used for ingest, it’s just not fast enough- A single camera at 4k will bring a gigabit network to its knees. IP networking is making it’s way into the events space, but it’s not straightforward, and generally isn’t used for critical recording or archival, just for pushing content to screens. For recording it is usually done in camera, and this is directly piped over dedicated cabling to back of house where a recording station is set up. This cabling will either be SMPTE or SDI.

    The most data I’ve recorded for a live event was on a show for a Tech Company You’ve Heard Of.

    We had 8 cameras in the main room. This room ran for most of the day, can’t recall how long but let’s call it 8 hours, allowing time for lunch and turnarounds and such. This show ran for three days. We kept to good practice, and had a main and backup recording of each camera feed. They wanted ProRes 444 HQ, I managed to convince them that 422 would be sufficient. Even so, at 4k, that’s about half a terabyte per hour.

    We could only get 2 terabyte SSDs in the quantity needed in time.

    So that’s 2 recordings of 8 cameras at half a terabyte an hour, giving 8 terabytes per hour, for 8 hours, giving 64 terabytes a day, for three days, giving just under 200 terabytes for the main room alone.

    Do you know how tall a stack of a hundred SSDs is? I do…

    I think about this in my workplace. I’m not on the IT side of things, but I do have more of an interest than most. And wow, it seems a mess.

    I think the problem lies with all these nifty solutions being implemented, and then suddenly it’s someone’s job to tie them all together, which they get halfway through doing before they are called off to do some other task… There doesn’t seem to be an overall architecture, or a coherent model of how information should flow around the business. I’m guessing you come across this a lot? How does that get solved?
