build own security system with veralite

Hi
I want to build a security system (EU-parts) powerd by veralite. What i want to ashive is to monitor 3 door sensors, two (PIR) sensors, two firealarms. In the hallway i want to use a tag reader.
Does somebody has experiance with building and controling your own security alarm with veralite? Sholuld i buy a dedicatet alarm?
Can i have a delay at the doorsensor in the hallway? So i can enter the room and disarm with the tag reader.
Do you have any tip of products i should buy (EU-parts) please let me know!
Thanks /Andreas

@ma00aem,

Welcome!

Generally, the recommendation here seems to be to go with a dedicated alarm system; one that is supported with a plug-in for Vera, so you get the best of both worlds.

Hello and welcome,

I would recommend a dedicated alarm. See thread below which address this same question.
