Has a psion5, brilliant tech. Loved it. The calendar was way ahead of its time, 2AA batteries gave weeks of life and you could just about touch type on the keyboard. If I could get it to synch with office I’d be tempted to dig it out again, it really was the future.

I have a couple of setups, one has poe ip cams writing to a surveillance nvr which looks after motion detect etc. The other system relies on the camera software detecting motion and writing to a Nas.

Both systems are on their own subnet and are firewalled from everything else. I VPN as and when required.

I’ve found motion detect with alerts to be difficult to tune to get good detection without false alarms.
