You put a lot of requirements there that will drive up the cost.
Yew, it’s all doable.
For a price.
Why not just use the standard ADT package?
Doorbell camera, camera out back (you can add up to 3 more), all motion sensing all night vision. Immediate phone alerts.
Speakers/microphones on the cameras. Motion sensors all over the house. You can remote in from anywhere and look at current view or past events.
Alerts via internet connection and cellular if you lose internet. Notifies the cop shop and/or fire dept.
$75/month, no purchase. All under maintenance.
I am not in a place where I need that.
Someone is always home
