Integrated domotic system

I want to integrate home dvr, alarm system and phone line with mqtt system for monitoring and controlling any house.

When the doorbell rings the camera image is showed on a raspberry LCD.

If the alarm is activated (no people at home the system call to the cellphone to answer the dorbell.

If one alarm zone is activated the video of the zone camera is showed on a cellphone video call.

All lights can be automated or remote controlled via mqtt

Redundant output comunnication for alarm, telephone, internet, GSM
