Best Cable for CCTV Cameras: FTP vs UTP Twisted Pair for 1200m Install Near Power Lines

Hello
I would like to receive an unambiguous answer as to the type of cable that is best to connect cameras to the recorder. Although the topic has appeared many times in discussions about monitoring installations, the day before buying over 1,200 meters of twisted pair, I would like to know whether to buy a UTP or FTP twisted pair.
From read posts on the forum I read that if the twisted pair is shielded, i.e. FTP. However, the man from the company that was supposed to install montoring for me claimed that the UTP twisted pair was pulled to the cameras because the screen may cause some image distortions, and the 230 V power cable going in parallel with the twisted pair will not cause interference anyway. I must admit that I have not heard that a shielded cable would cause interference by itself, because this is the assumption of the screen so that the signal flows in the most neutral environment without the influence of other signals.
in my case, the distance from the cameras is from 50 meters to 130 meters, and the cable I want to use for category 5e.

But is it supposed to be FTP or UTP ??

I am asking for advice as soon as possible because tomorrow at 8 am I have to buy it.

In this topic, you have everything you need to know. Types of wires, etc. after searching the departments. http://www.dipol.com.pl/bib21.htm

Here I enclose the parameters of the twisted pair http://www.dipol.com.pl/bib34.htm

according to text in this link comes out to be unshielded. And when you read on the forum, people write that when you install a twisted pair, it is good and shielded because it is more exposed to interference.
So using FTP twisted pair will be a mistake ??

Ok I understood.

The shielded twisted pair must be justified under the conditions in which it will have to work. I assume that a large number of lighting power cables located near such a twisted pair will not affect the signal.
The installation is to be located in a large grocery deli, where the twisted pair under the ceiling will intersect with a large cobweb of lighting cables.

The bottom line is that no one wrote that shielded twisted pair could have a negative effect on the signal and would by itself interfere with what it should protect.

If anyone else has something to add, please feel free to contact me. I will listen to the suggestions of experts.

And so it will be placed as you write, however, some things cannot be avoided and I will just add that the first installations were suspended over thirty years ago and along with the modifications to the building, more cables were added.
Generally speaking, I cannot say whether it is possible to route the twisted pair away from other cables for a distance of 130 meters. I sincerely doubt. However, 90% of the wiring is definitely from alarm and lighting systems. Cables to the motors from the air supply may occur.
with such assumptions and in total unknown in what environment the twisted pair will hang, should I add cash and buy FTP ??
If FTP does not cause internal interference due to the shielded cable, it is no problem for me to spend more money and buy a shielded cable.
Can anyone write clearly whether the screen in the FTP cable is causing this noise or not?

ok. I know exactly the same that the screen itself is there to protect against interference, not cause it. Hence my surprise when the monitoring expert told me exactly the opposite.
Then there will be FTP shielded twisted pair

In such situations, it is extremely important to properly install the shielded twisted pair, i.e. to ground it on one side and to use only one grounding point.

You have exactly how to connect the screen. If you connect the screen at each end of the line, it becomes a source of interference by itself, connecting different potentials. The topic can be developed but that should be enough.

I understood? If the twisted pair shield is to do its job, do I need to ground it? So I can connect it to the protective conductor at the recorder? How does it work in practice? Greetings

You do not ground, but you connect to a common point (most often the metal casing of the recorder). However, the screen must not be connected to anything at the other end of the shielded cable.

Hello. I ran the longest section on a twisted pair, about 400 m, using an XZTKMXpwn overhead cable with a 5 x 4 x 0.5 cable. The cable is not shielded and the camera image is clear. I very often use UTP cables up to 200 m long, led under plaster in buildings. If someone shows me a CCTV installation in an industrial building, where the amount of cabling for the electrical installation, alarm system, teleinformation system, I will not mention CO and sewage water with the maintained distances recommended in the standards and posts of "wise men", I am a bishop or even father R. And so on by the way, the shielded cable is STP and the FTP is a foil cable with an additional grounding wire. Summarizing the above, I do not see the need to use a much more expensive cable in a screen or aluminum foil (FTP). Regards
