Hello everyone,
we have a single-family house (completed), and I am currently looking into IP video intercom systems.
First, about the existing installation:
We have a Cat 7 cable next to the front door for an outdoor station, as well as two Cat 7 cables on the ground floor and upper floor for connecting indoor stations. Each cable runs back to the electrical cabinet in the basement.
An electric door opener (not a motorized lock) is installed. Its wiring also runs to the electrical cabinet in the basement.
After reviewing several providers, I keep encountering the following issue:
Outdoor stations are usually connected directly to the door opener. In my case, however, no cable runs directly from the door opener to the outdoor station.
So far, I have only seen the solution from Doorbird, where the door opener is connected directly to the PoE switch and has no direct connection to the outdoor station.
My specific questions are:
1. Do you know of other providers where no direct connection between the outdoor station and the door opener is required?
2. Am I possibly misunderstanding, and could the outdoor station still be connected to the door opener?
3. Is it common in new builds that electricians no longer run cables directly from the outdoor station to the door opener?
Thanks in advance.

Thanks in advance.If you run the cable from the outdoor station to the door opener, anyone who removes the outdoor station from the outside could short-circuit the door opener and open the door. So you should definitely avoid that.
I recently installed the GOLIATH/Dahua video intercom system and mounted the corresponding security module in the distribution box.
This is exactly what you want.
Depending on how many wires are needed, you can also route the signal through the distribution box with any standard system, keeping in mind the above-mentioned disadvantage of the short-circuit risk. You have a total of 8 cables available.

Thank you for the quick response.
I would also like to use PoE.
So, could I simply connect 6 wires of the Cat cable to a PoE switch via RJ45 and use the other 2 wires for the door opener?I found a link in the IP Phone Forum to a blog where exactly this was done with the Goliath or Dahua systems.
I had thought about that too. But since I added it later, I simply ran 2 cables to the outdoor station for simplicity.
P.S.:
If you search for it, you should find it on a site with “Wolf” in the name:
“Connecting the Dahua VTO2000A with a LAN cable”

However, this only supports 100 Mbps, as is typical with older economical cabling. I cannot say how manufacturers currently implement PoE.
Is your LAN cable to the door station run inside a conduit? If so, you could pull a thin cable through it.
Great, thanks again for the helpful tips.
Unfortunately, I have to say that this whole thing seems a bit overwhelming for me, so I’ll just ask a very simple question before I dive deeper into the topic: which wires do I use and how?
I strip the 8 wires of the Cat7 cable, then take 4 of the wires, connect them to a keystone adapter, and thus have my LAN cable, which can also carry PoE. From the remaining 4 wires, I take 2 and connect them to the Goliath security module, as if they were dedicated cables for that purpose. I simply ignore the other 2 wires.
Is this correct?
