Recommended Video Intercom Cable for 300m Distance: Gate & Alarm Control, Wire Cross-Section

Question

Hello, I need to lay the cable for the video intercom and to open the electro-catch and extend the gate opening signal from the remote control or home button to the gate and alarm detector. the situation is that the building is 250-300 m away from the entrance gate, I have an erbette at the gate...

The manufacturer of a given video intercom always gives recommendations regarding the cables.
As for Vidos, recommendations over 75m are 1mm cable. Number of wires minimum 6 but add gate control 2 wires plus some spare. Of course, you need to make the power supply for the gate station and the electro catch locally at the gate.
My advice is about the Vidos analog system. If you have any doorphone set you have to check the cable requirements because the distance is large.

Until recently, none. Now I think it is: Requirements will really be similar for different manufacturers, but with such tables in this case, please do not suggest. They are very indicative and many times their authors confuse 0.5 with 0.5 square. Knowing the power consumption of the external cassette, simply use the voltage drop calculator. Please do not suggest that you can talk and see. It is important that the relay responsible for opening the gate is activated. Proposed solution: video intercom whose design provides an additional power supply for the electric strike (commax - I tested at such a distance, vidos - I do not have such experience) hitch power supply locally from the gate power supply. cable in gate / wicket relation min: https: //www.speckable.pl/produkt/4242/Kabel-telekom.-zel.-XzTKMXpw-5x4x0,8mm.html? ref = g95 Yes from experience with commax. Two fours with a considerable supply of power (we once launched commax on single 0.5 wires at a cable distance of 75 m. If the 0.5 conductor has a square of 0.2 and the conductor 0.8 almost 0.5, then count how many he lived really since poverty is enough), one four with audio and video supply (single veins are enough), one pair for gate control and one pair in total storage. In the place of mounting the camera and monitor, it is worth providing space for the installation of passive transmitters and overvoltage protections. best regards ps. it is worth providing the possibility of connecting an additional camera at the gate and an additional (this time at home) remote control receiver which sends a signal by opening the gate (we can open the gate confidently at the house) ps2. of course, if you have the right budget, it is worth placing an additional gel strand along the previously proposed cable - just in case. ps3.cable at home we run through a mini switchboard with access to 230V. There we can place any additional devices.

We installed several Urmet 2Voice sets at similar distances. Last month e.g. http://www.miwiurmet.pl/katalog-produktów-domofony/item/319-zestawy-video/1673-1722-671.html
The cable is a UTP gelatinous twisted pair cable, and according to Miwi Urmet's recommendation, we only let it go one pair (we didn't pair). It works without a problem, and several other sets have already fallen on these distances before.
Interestingly, the manufacturer (Italian Urmet) claims that this pledge works correctly on UTP up to max. 190 m. The distributor in .pl is already after many tests for 2 x greater distances than the factory suggests and is OK.

best regards

Or maybe you don't have to buy cable and buy a video intercom with the function of opening the gate and gate up to 300 m wireless?
Maybe someone has a proven video intercom with such functions up to 300 m, I would love to buy the same

Added after 4 [minutes]:

One detail when it comes to the wireless video intercom over a distance of 150 m from the gate towards the building, the plot is forested, is this a big problem?

I don't know if you will find a video intercom at such distances. A sensible video intercom set is the Comwei WB201B but its effective range is 50m, according to the manufacturer.
Personally, I would go into a cable with appropriate cross-sections.

[/ Quot If I decide to lay the cable, XzTKMXpw 6x2x0,8 12 wires should cover it all and tell me if I will have two wires free, can I use the same cable to get the internet signal from the fiber or place the fiber separately at home?

Dude, if you are talking about fiber optics, think about IP video intercom.

Hello, I used to mount a video intercom at a distance of 400 meters. A 10-pair telephone cable, and it has been in operation for 6 years. The problem was that I had to use two power supplies. One at home, the other at the gate.
best regards

If you have hectares, you have to take into account the costs And by the way, when you solve the @Ircys solution, you save a lot on the cable. Worth considering. best regards

An IP video door phone at such a distance does not have to have an optical fiber .. If there is electricity there, try using this: whoop_network_devices & cmpid = 61148 & gclid = CIqtsrup7dQCFdLJsgodlQYEVw On the other hand, remember to connect the device on the same phase and distance up to 500mb. I tested on about 140mb .. But I think that up to 500 it is 300 it is calm .. best regards
