Can anyone confirm wiring diagram for this DS-2CD2043G2-I(U).
Is this diagram according to pdf correct for this model ??

Wiring diagram for water damaged rj 45

There is no wiring diagram, dont use ones found in Internet from 10 years away, hikvision can use different pcb versions with different colours (in same ipc model without additional information or version mark). Its best to check arrangement with old socket pin by pin (pin to colour).
If your old connector failed due to corrosion then if you still have it use multimeter (to check which pin corresponds to which colour). Even corroded one should be easy to connect.
In worst case scenario, it may be necessary to open the connector. But still its more safe solution and will work for that camera (again, other DS-2CD2043G2-I could have different pin-colour layout).
E: if camera is still under warranty then you can also contact your supplier, hikvision can repair those with small fee/no fee, depending on case.

I've cleaned up worse than that with a toothbrush, dental pick, and contact cleaner. But if you're set on replacing it, you can cut it off and make your own wiring diagram with multimeter as stated above. If mine, I'd try like heck to save it first.
No bro...I also want to save it...I sprayed it with isopropyl alcohol but not rubbed it...will rub it with toothbrush
p.s. thanks for help

That diagram is still valid, no reason not to use it, except that -
Note - on the later (G1) cameras, Hikvision have swapped pins 4 and 5 (Grey and Purple).
Thanks for the help. Installed keystone jack with above color code with swapping grey and purple. One problem after putting dielectric grease in rj45 female connector is connection drops sometimes. It comes again when I restart poe switch. Can you point me my error. I have taped it with silicon self vulcanizing tape and then with 3m 33+.
I don't have a Hikvision camera and I have not replaced a RJ-45 connector on one. Also, I'm not pointing out the following because I think it will resolve your issue about having to restart the POE switch but the pin numbers of the image you posted are wrong IF that is a female RJ-45 and the latch is at the top.
If that is a female (jack) which is what is on the end of a camera pigtail then they should be reversed as show below:
I've re-wired dozens of camera pigtails and crimped hundreds of RJ-45's and in many cases it DOES matter, especially with passive POE. Thought you'd like to know the pin numbers as shown for the female RJ-45 are incorrect.

I didn't mean to undermine you. I punched my keystone jack by t568b color coding marked on keystone jack so didn't feel to check pin number. Only thing I changed was swapping grey and purple. Now I am clueless, why my ip camera dropped all of a sudden without any physical strain on wire and came back after restarting poe switch.
I crimp my rj45 referencing this.
Nice diagram, eliminates all of the front/back/rightside up/upside down confusion that's hit me about 500 times. I eventually made a somewhat similar handwritten diagram.
Update: Camera worked after above color code but was losing signal on vibration. Viewed my cat 6 cable and it looks like this from 3 places.
Can this be the reason for signal loss ??

It's possible, it looks like it's been chewed on by rodents.
Not chewed but damaged because of neighbors construction work. Wire was coming from terrace near his boundary. Should I replace whole 20 metre length or keystone jack can work replacing damaged part ?? Camera is poe.

I'd replace the full length.
Be sure to use Solid Pure Copper cable, not CCA cable.
After much research, I have now came to a solution that camera pigtail has stranded wire and I was punching down pigtail wires which makes connection drop. I think I should crimp pigtail wires with rj45 connector for stranded wires and punchdown my solid cat 6 wire. Can someone point me in right direction ??
