I had the same thought. They say memory, but it’s unlikely they mean RAM here.

512gb of SSD should fit 5 days x 2 HD cameras @ 30fps, so I’m pretty sure that’s what they mean.

I thought RAM too, but that'd be overkill even for a workstation I'd try to slip past the purchasing dept. Though the rest of the article makes it sound like they're streaming it to a central server, so that's a pretty beefy local buffer.

I guess it'd be appropriate for a local fallback if the network connection was dropped. Shouldn't take more than 5 days to get back up.

The reporters strength is not tech it seems, it is indeed a 512 GB hard drive that is part of the system.

Additionally it has a range of detectors, even a Gunshot detector.
