How to organize video surveillance at 300-350m.?

Question

CCTV

good evening.
I want to organize video surveillance on my street with a length of about 300-350m.
12 poe cameras ip hikvision
registrar of the same company
has 2 poe switches from the same company for 4 channels and 3 more poe switches from another company also for 4 channels each.
I don’t have such experience, I want to stretch over a twisted pair cable, there is no way to stretch optics, I don’t want Wi-Fi either, because there are a lot of bad reviews.
if you install poe switches every 100 meters, it will work fine, mb who has experience, and another question, for example, 3 cameras will be connected to one switch, from there one wire goes to another switch, etc. the rest are the same, that is, one wire will go to the registrar? or should each switch have a separate wire to the central switch?

Answer 1

1. 30 cameras hang on outdoor Nanostation M2 - it has been working like a clock for 5 years. I don’t know what bad reviews about Wi-Fi can be.
2. It is not necessary to install switches. You can try a PoE extension cable, it will be cheaper and the circuit seems to work.

Answer 2

will work fine

Answer 3

Only it is better not 100 meters, but 70-80 further problems often begin. Measure the distance along the cable and check the "consistency" of grounding between buildings.
mikrotik has a compact poe-powered repeater and a ready-made outdoor clutch for it.

Answer 4

Another question, some cameras lose connection sometimes, they advised me to put a gigabit switch, I have 100 Mbit po switches, which switch should I put? Is it necessary to eat or can I have an ordinary one?
