Door intercom system

[Hard-Drive]

Guys

I'm after an intercom system for an electric gate. This is the spec I'm looking for.

Must have:

Run off 12v or 240v at the gate end
Wireless connectivity to the house end
Voice Intercom
Backlit so you can see it at night
Video link to the house
2 x handsets/monitors in the house
Facility to trigger a pulse signal to the gate motor control board from the house
Waterproof
Tough case

Nice to have:

Smartphone app with remote gate release
Ethernet connectivity
Record function

Any recommendations at all? Thanks in advance.
