Customer has a gate access to their property. They would like to have the call button ring to their cellphone and be able to see who is at the gate and then let them in. They are planning on forgoing a land line.

Should be able to get whatever type of wiring we want there and have it hard wired to the houses network.

I've not done much access control like this and wondering if there is a good place to start looking or if anyone has a product that could accomplish this.

TIA
