| A 7U cabinet in an overhead space that is difficult to access. Installation and configuration were a bit of a headache but ended up being worth it. There was a NAS in the office and they stripped 7 drives, sleds and all, out of it. I'm guessing with such an obvious endpoint for the camera storage it never occurred to anyone there was a second box. I had something like this in mind when I wired the building. It seemed like a good idea to make onsite security footage much harder to find given the cameras were obvious and anyone breaking in would probably look to damage or destroy the system. I really thought the cameras themselves were the deterrent, but these guys gave it a shot anyway. Cutting the cable to the starlink and walking off with the NAS drives seemed to be the plan. In the future I'm going to add a local battery backed alarm connected to external siren and strobe that is immediate on opening the office door to draw attention. I was driving down to WWDC when the starlink went offline and saw the notice on my phone but wrote it off to equipment failure which gave them enough time to clean the place out pretty well. The hole in my strategy was thinking nothing could happen without notification, but being in a car in the middle of Norther CA with spotty cell coverage and lots of distractions blew that up pretty hard. I'm also thinking one of ubiquiti's cellular backups is in my future. Starlink offline is annoying but not the attention grabber that a still of a guy walking in the door would have been. Cellular backup would have gotten me that. |
But, re: alarms, I'd like to add a suggestion: Indoor sirens. They can be intolerably, painfully loud for not very much money (because piezos are cheap and square waves are easy). Using a small, random mixture of them can let them beat at different frequencies and periods, which can make them very unpleasant to behold even with hearing protection.
If you feel like being clever, you can even run them with a local battery that activates when they're disconnected. If you feel like being extra-clever, you can make them activate when they don't have the correct termination resistance at the far end of the line, or exactly the correct voltage: This way, whether the wire goes open or short, the sirens activate.
Super-extra bonus points for using a combination of methods. Any time that a thief spends figuring this out is time they aren't carrying stuff out.
And if that still seems incomplete, then: Fill the shop with smoke. They can't function when they can't even see their hand in front of their face. https://www.youtube.com/watch?v=RPgcysyFUiI
