Newbie with POE Cameras
I have always went with wireless in the past, but i am tired of the not so good quality and decided to go with wired cameras.
My house is PRE WIRED, i have CAT 5 cables at each corner of my house. And they are T568A.
One end of the cable goes into my structed wiring box, the other end by each corner of my house, i had to crimp the RJ45 connector on.
When i plug the end from my wiring box to my NVR, and with the camera plugged in on the outside, my camera does not power on.
But when i plug in the camera with a supplied reolink cable directly to the NVR, it comes on.
Any idea why that is?

T568A refers to the way individual wires in the cable are located within the RJ45 connector. As long as each cable is terminated the same way at both ends, it is possible to mix T568A cables and T568B patch cords. There are many articles on the web describing the differences.
Typical wiring installation has the same type of connector on both ends of each cable, i.e.:
- Cables embedded in the walls typically have an RJ45 jack on each end.
- Cables used to 'patch' between pieces of equipment typically have an RJ45 plug on each end.
What the post "sounds like" is the house wiring ends in a patch panel on one end (RJ45 jack) and was not terminated on the other end (where you crimped on an RJ45 plug). It may be a bit awkward to gain access to the back of the RJ45 jacks in the patch panel to visually confirm that pins 1-8 have the same color/stripe as the RJ45 plug.
Reolink uses the 802.3af standard for Power over Ethernet (PoE). (search for a Wiki on Power over Ethernet) They also use 10/100 ethernet (probably a bit less expensive components than 10/100/1000 and since the cameras output no more than 20mb/sec, there is no need for gigabit ethernet capability.
I can't guarantee that this is the problem, but when the camera gets power using a regular ethernet patch cable but not when using the house wiring, that is where I would look first.
So the house came with the Panel where all the cables and what not is located.
That end of the Ethernet cable already have a RJ45 Plug installed, outside my house the cables are not terminated , which i personally crimped on a new plug over.
The coloring matches the plug inside the house as i made sure of that when i crimped the new plug on.
When i plug in the RJ45 inside the house into the NVR and the outside plug into the Camera, it does absolutely nothing.
- The biggest issue I come across is poorly terminated cables. Have you tested the cables? A network cable tester will tell you definitively what the issue is (if it is a cable problem) - search for Network Cable Tester into screwfix or amazon.... less than £10.
- Have you tried connecting a short ethernet cable (like something you get with a router) and plugging it into the camera near your panel? If that works, chances are it could be the cable to the corner of your house.
- Also, have you ensured that PoE is switched on, on the NVR? ....presuming it is a PoE NVR!
Last night i went and purchased this here (LAN Scout Jr. 2 Cable Tester
When i plug in the prewire that came with the house, it shows absolutely nothing on the tester.
Perhaps maybe it is the wire that have problem....
I did tried it with a shorter cable that comes with for say a router/modem plug into the NVR and the camera and it does work.
@ivan_488740454707352 I would suggest re-crimping the RJ45 plugs again. Do none of the pins show as connected on the tester? it should show an LED for each leg of the wires. It is highly unlikely that they are all broken/high resistance.
The other possibility if they are all showing as above, is that the cable is cut/rat chewed!
Not knowing the set up as well, check the panel and plugs at that end.... is there possibly another intermediate connection box?
The tester i bought basically shows 1,2,3,4,5,6,7,8 on LINE 1
And on Line 2 is where it confirms if it is wired correctly, when i have the house pre wires plugged in, nothing shows up on LINE 2 .
I will take a pic of the Panel box tonight upload it here for you to see.

The cable tester provides another check as well. Is the label on the patch panel accurate. My soccer group moved into an office complex that had been wired by the previous tenant. There were jacks in every room, but the patch panel had no writing on it. My first task was to go around with the cable tester and mark each jack on the patch panel.
The patch panel may say the cable terminates in the NW corner, but is that really where it goes?
I also used a telephone circuit for the same purpose. Plug it into the remote jack and then stick the speaker into each ethernet jack until a tone shows up on one of them. Would work with your bare wires. (Search Amazon for 'circuit tester'. Their #1 seller is under $30.)
There are 16 wires inside the box in my house.
I dont know which one is to where, but i plugged all 16 into the NVR, with my 1 camera plugged in outside. And i guess the camera never connected because in my monitor it never populated any pic or anything at all.
So then i bought the tester and plugged each and every one of the 16 cords into the tester, one at a time and the tester showed absolutely nothing
@ivan_488740454707352 when you say 16 wires, do you mean cables? Why do you have 16? Can you upload a photo?
If it is 16 individual wires (onto 4 plugs) then that could be the issue as PoE will generally need all 8 wires (4 pairs) terminated into the RJ45 plug. Can you confirm....
So when you put cable tester on cable in your house, you are putting the remote tester unit on the other end? You need to put the remote unit to test the cables and provide loops etc and check for for cross pairs.
I don't know your experience with testing, but if you search on YouTube "how to test ethernet cable" there are some useful guides. Have you tried this with one of the other 3 positions where the cables go to?
The other possibility as I mentioned before is that there is another intermediate panel somewhere? It is highly unlikely that both the camera and the tester are going to show nothing for all of the cables. Is it possible that someone has done some DIY and cut through the cables? Major rat issue? rats love chewing cables
