Wiring for 2 sliding gates and a wicket - IP video intercom, diagram, model selection

Hello,
I am appearing to ask for help in laying out the wiring for 2 sliding gates and a wicket. I have watched a couple of videos and have put together a rough diagram. I would like you to direct me if there is any mistake what needs to be changed.

My plan is to be able to control from a monitor:
- Garage door
- Entrance gate (in the diagram "Gate 1")
- A wicket
I want to have an IP video intercom, which I can also use from the app to open or close the gate, watch who is calling on the camera, etc... According to my information, I need an IP video intercom with 3 relays (please correct me if I am wrong) but I have no idea where to look for a good model.
In the diagram, all the cables will go down to a box signed "M£" and to this box I will run a twisted pair cable in order to locate the PoE switch and connect the video intercom to power.

In addition, I would also like to connect both gates (Gate 1 and Gate 2) to the garage door remote control (garage door from Krishome) if possible. Is this a possibility or is it too much trouble?

I hope I have written everything I need to help, if I have left something out I will be happy to answer questions.

Thank you in advance for your answers .

Hello... Surely you have overlooked the distances, because for example with 30 meters of twisted-pair cable the power supply voltage of HIKVISION video intercom at the wicket can drop by half when using an inadequate cross-section to the distance and after a few years not only due to the cross-section but also corroded contacts, so for powering the video camera at the wicket I advise against twisted-pair cable, unless you put it twice and double the cross-section on the power supply ... Therefore, plan exactly what you want to use, how many wires and cross sections appropriate to the distance, this is not my theoretical idea but the data on the maximum distances of the installation in a given cross section can sometimes be found in the video intercom installation instructions and in practice why then dig a second time for another or additional cable? Sometimes it is worth to provide thicker PESZLE (AROTS) and when laying them, ensure the possibility of their later modification, which is a reasonable idea in the case of devices changing every now and then... As for the choice of the model of devices, probably someone who assembles such devices every day will have more to say than me.... In addition, I know from practice that dogs can take an interest in peslas and cables in them and effectively chew them, so think at once about protecting their ends from access by outsiders and any rodents....

I will indeed have to measure distances, what do you suggest if I exceed this distance? Change the twisted pair to 3x1.5mm2 for the power supply and 8x0.8mm2 for the example? If so, what about connecting an IP video intercom, falls off then?
