Installation / wiring in the house for video intercom / IP intercom

Hello, I have a question about the correct arrangement of cables for installing a video intercom.
I have a strand buried in the ground (of course in a gel) it enters the building, my question is:
1. Can lead the cable to the multimedia or electrical switchboard.
If I bought a video intercom with a DIN rail power supply, then I have a place for it in the electrical switchboard.
2. If I used this power supply for DIN in an electrical switchboard, do I have to get to this power supply with this twisted pair from the gate? Next, next to the multimedia switchboard and connect it to the router there, if it is to be an IP video intercom?
Or maybe fly this twisted pair straight to the multimedia switchboard, and release only the power cable from the power supply?
3. Is it possible to somehow coincide with the opening of the entrance gate - there is also a second twisted pair and a wire to supply 5 wires goes along the fence.

I am asking for some picture diagram of what cables to release, so that it does not turn out later that I gave too few of them under the plaster.

I would like it to be possible to connect two screens permanently on the walls (top and bottom), although it will be possible to fire on the smartphone and tablet via IP.

1,2 Why multiply entities and cut this wire. How does a colleague know that the power supply from the intercom will be for a DIN rail? Both the future power supply and the twisted pair are best if they reach a multimedia switchboard. The only question is about the distance and whether the future intercom will also power the catch.
3. This wire runs from? down?
Maybe some sketch please

I corrected the title

1 twisted pair goes from the gate, 2 from the gate + 1 cable 5 wires from the gate goes past the gate and all cables enter the building in one place.
The building is still before plasters, so I ask you not to make mistakes when laying cables.

This will connect a friend with a twisted gate and a gate. I asked about distance or do I just think? What cables did the colleague lay under the monitors? I would give there a twisted pair + power supply all led by roz. multimedia

Twisted earth length about 20 m to the building.
Length from the building wall to the switching station about 10 m, including a total of 30 m.
I haven't given anything yet.
Why give a twisted pair between a gate and a gate?

This allows you to make the right connection and control the gate and gate ..

So giving a twisted pair between the gate and a gate for this 2 twisted pair home and a 5-wire power supply cable at the gate is enough?

I understand that this 5-wire cable is for powering the gate and not intercom?
Yes, having a triangle installation can always be done.
Regards

yes cable to power the gate.
And out of curiosity whether this twisted pair between the gate and the gate could not be replaced by connecting these cables at home (since there are separate twisted wires from the gate and gate, the connection could be made inside the building) e.g. cable from pin 1 from the gate needs to be connected to the gate No. 2, i.e. at home, connect these two cables together and I have a connection between the gate and the gate

A colleague himself will assess which solution gives more possibilities, is more universal. The cables in the house are connected in one place anyway.

I have a few more questions from fellow experts on the subject of IP video intercoms

1, how do I enter a twisted pair cable from a doorphone to a multimedia switchboard, can I use this switch to transfer the image to 2 monitors on a twisted pair cable and to get the image via WiFi on other devices such as a smartphone or tablet?

2 from the switchboard I gave a 2x1.5 mm cable to power the monitor at the bottom and top depending on whether I need 230V or, for example, from a 12v power supply, so I only ask for a hint whether on the wall where the monitor will give a box or just put out the cables (I thought about cans of such square flush-mounted) how do you do it professionally?

3 can you somehow rip the doorbell with such a video intercom so that the bell sound is heard through the monitor or are there video intercoms with this option?
If it is possible, should you also give twisted-pair cable from the monitor door bell?

4 is one twisted pair per monitor enough?

Without going into details - yes

Give a can of classic Fi 60, for example

It depends on the model, but if you are at the stage of laying the cable, then give UTP in this relationship.

One twisted pair is the minimum, it's always better to give more.

thanks for the answers
