    The cloud is not the problem. Inadequate local buffer is the problem.

      If it’s got local storage, it’s not ‘cloud based’.

      I’m not saying offsite backups of your local storage are a bad idea.

        I didn’t say storage. I called it a buffer. No permanent local storage needed

      Wifi jammers could knock it out before the camera sees anything.

        The jammers don’t disable the cameras, they just prevent them from streaming the captured video to the recording machine.

        If the cameras had a local buffer, they’d be able to keep recording even if the signal was jammed.

          Until the cameras are destroyed, which is easier to do when they’re not streaming in real time

            Why not both?

            Mains power with battery backup, live streaming via wires with wifi then flash storage backup

        You cannot block a camera from seeing by jamming the wifi. It could simply save the video feed locally and send it to the server when the wifi is restored.

            You can still just restore the network and wait for the camera to sync. Feed not lost unless too long time has gone by and buffer has wrapped around
