Smart intruder alarm recommendation?

Our 30+ year old system has taken to false-alarming and so it's time to replace it.

Can anyone recommend a system to look at? I'd prefer something smart that will integrate with |Home Assistant.

When did you last change the rechargeable backup battery in the control panel? They only tend to last 5 years (or less). Although the terminal voltage may indicate the battery is OK it cannot instantly supply the power when you get a small dropout of the mains supply and this can trigger the alarm.

Thanks. Probably six or seven years ago but the system is on its last legs and owes us nothing so It'll be replaced as soon as I can find something decent.

Don't know anything about Home Assistant but I recently updated my system with one made by Orisec - it's what the installer specialises in. I'm very satisfied. I had the wifi module installed, so I can access it by an app and it will notify me if anything triggers while I'm away. The installer saved me £100 by saying that the existing sensors were still current and did not require changing. He also sorted out a couple of bodges made by the previous installer. The existing wiring was reused.
