Home automation: Integration of gate, intercom and camera, online viewing of 4 cameras and managemen

Hi

I am facing the purchase and integration of several systems:
-automatic gate controlled with buttons and remote control
- intercom with camera controlling the gate.
- 4 cameras with online viewing.

+ a system integrating the above that allows viewing from cameras with the possibility of remote gate, gate opening. (occasionally, however, this is important to me)

+ Future programming of small devices such as electronic thermostats, firing the boiler by time or on the basis of an added sensor.

What would you choose?
Home assistance?
Integra?
Supla?

I would put my money on Integra but that's just my feeling.
