Re: A crime occured at my neighbors in my camera view, but my hard drive was unplugge
That sucks. Hopefully there's in-cam storage via SD card. If not, then unless you've got something else set up that we can't know about from here then I'd say you've got nothing.
Things like that are one of the reasons that a dedicated PC for your camera system is highly recommended. If it's not used for anything else then there's less change of something getting touched, changed, unplugged, or installed that's going to bugger up your video records. And that's if only one person is using the system. Double the users probably has four times the chance for screwups.
I don't use a dedicated PC but that also has its advantages when I'm the only one touching/changing things. Every time I'm on the computer I check that things are running properly. In addition to
Blue Iris, I use edge storage with some of my cameras. Internally to SD in the cams, and streamed to NAS on a 3gig external USB drive plugged into my router. If the computer crashes or gets stolen/smashed I've still got storage in-cam and on the HD. Purists will laugh at calling a USB drive NAS, but it IS storage attached to the network and works as such.
