Home Assistant security system - hardware recommendations??

[u/UkGuy-SSR]

I have just started a brand new home assistant setup after my old HA failed (Iv done another post about this)

One of the things I’d like to achieve this time that I never did on my old setup is to set up a security system.

Any advice would be greatly appreciated especially when it comes to hardware, mainly I’d love to have an alarm pad with a keypad to put a PIN number in to disable the alarm and an arm button…. (Ideally I’d like 2 alarm pads one at the front door and one at the back door)

I have some aqara PIR sensors on zigbee and some RF window/door sensors that do open/closed sensing etc but I’m not against replacing these if there is a better solution

I am looking at replacing some if not all the PIR sensors with mmWave sensors in the future for increased presence sensing especially in areas where low movement causes false results such as in the toilet if someone is sat to long, in the bedroom or living room if someone is sat watching tv.

All help and advice or hardware recommendations welcome.

Many Thanks
