IP camera at a distance of 94 meters?

Question

CCTV

Good evening! Today I connected video surveillance for the first time.
There is a Hikvision IP camera with PoE support, a TP-Link TL-SF1008P switch with PoE support and 94 meters of FTP cable 4x2x0.52 category 5e 24AWG between them.
The cable rings perfectly, but I don’t see the camera on the network.
On the switch, each PoE port has 2 indicators: PoE and link. PoE is on, link is off.
I came to the conclusion that I encountered attenuation. The cable is laid along the facade along other wiring and other wires.
How to be? I am already lost in the variety of equipment and do not understand what I need.
What do you advise?

Answer 1

I'll try to stick in the middle Mikrotik mAP 2nD

Answer 2

1. Remove the camera (or bring the switch to the camera) and check on a short wire.
2. Cut off a long piece of wire about 100 meters and test on it.
3. If it works on a short wire, but not on a long wire, check on a 100-meter piece of category 6 cable.

Answer 3

I use this thing on long lines.
Ethernet signal transceiver with PoE RVi-PE
Powered by poe, and it also powers the camera.
Expensive, but reliable and unpretentious.

Answer 4

Reduce the length of the line or put a switch somewhere on the line. From our own practice, a 105-meter line worked, but it was laid through cable channels away from power lines. Again, from our own practice, we check such long lines from Fluke Networks Microscanner2 (the cases were different: they stretched a 60-meter line, it turned out that the cable was not clear whose production, somewhere in the middle of the line there was a short 2 pairs, without Fluke they would not have known). In general, a spacing of power lines and SCS is necessary, if the memory does not change at 100 Mbps - about 10 cm, 1 Gbps - 30-50 cm

Answer 5

The length should be enough, try turning it on without POE, just in the router and in the laptop. If there is no link - the problem is with the cable or with the router.

Answer 6

also see if the cable is copper or not. For if it is a GOOD copper twisted pair cable, they also launched PoE cameras at 110m + (although yes, this is already luck). If the cable is copper-plated. aluminum - that's the jamb. How to find out - see the cable marking, read on the manufacturer's website and .... SUSPENSION. According to personal experience - a bay (305m) of a copper twisted pair of 0.51 sections without a screen weighs about 12-15 kg.
Here people have already written above - check the link on the PC. Call the testers for the integrity of the cores and their correct crimping (and whether the cores are crimped in the connectors - often this happens!)

Answer 7

What tester do you check the integrity of the cable? It happened that when it was connected to a switch or other network equipment on one side, the tester gave out a fully working cable, but when a plug was placed on the side of the equipment, more objective information was given, it determined one or two non-working cores. Often encountered this.
Try to swap pairs, where the link is, start the power, where the power is the link ...
