Hello everyone! I am beginner for these things and i have been fiddling with my settings for almost week now without any progress so im here to seek help.
i have dahua POE nvr and 3 domes that i got to work couple years ago and all i remember is that it was long battle, and now there has been people at my property so i decided to get more cameras. i bought two used ptz cameras (dahua and hikvision) when i first connected dahua cam everything worked fine. then i tried to install hikvision camera and i managed to make my situation worse. Now even dahua ptz camera doesnt work anymore. I have tried to fiddle with ip addresses, downloaded different softwares, connecting cameras to pc,nvr and modem, and nothing seems to work. im getting really frustrated because i cant find solution no matter how much i try to research. if anyone would be so kind to help i would appreciate it very much.

some extra info:
nvr DHI-NVR4104-P-4KS2
dahua ptz dh-sd59230t-hn
hikvision ptz ds-2df7286-aw

​

 
It looks like NVR DHI-NVR4104-P-4KS2 total output power is only 50W, max single port power is 25.5W. Your 2 new ptz cameras probably exceeding the max power the NVR can provide for all your cameras. Especially the Hikvision ptz usually even more power hungry than the Dahua ptz.

Have you try remove all other cameras except the Dahua ptz, will it work that way?

Connect them to an external PoE switch with more power?

well it worked at beginning (3 domes and 1 dahua ptz) so it should still work? i was thinking if i should invest into POE switch but i figured i should ask from someone wiser than me. ill try to get it work without domes connected. thanks you for you answers

It might have worked during day when cameras were not pulling more power for infrared. Or as the unit ages or a little corrosion on connectors and it needs a little more power than when everything is new.

Thank you all for for you time. I found used Ubiquiti EdgeSwitch 8 150 W. I think i will buy this switch and then i will try everything again. if someone sees problem with this switch i would appreciate if someone would enlighten me with those problems

​

 
oh. Im glad i asked before buying. So if i want to play safe i should consider dahua. i found also used dahua poe switch PFS4226-24ET-360. i was thinking it had bit too much ports but maybe i will buy more cameras in future and it wont hurt. can there be problems with hikvision camera and dahua switch?

Not likely, BUT just insure:
  1. The POE switch is 802.3af, at or bt compliant (suffix depends on power capability)
  2. The POE switch can supply more than the sum total of all POE cameras connected, using their maximum current draw specifications.

these numbers and their meanings go way over my head but yes this dahua switch has 802.af and 802at PoE protocol and can supply 360w. so if i have 2 ptz cameras and my dahua needs 23 W and hikvision ptz (53max?) plus couple small domes so it should be more than enough?
also it has 2 ports that can give 60w and rest can give 30w. am i interpreting this correctly?

As long as the max draw of all cams added together does not excced the max rating of the switch, you should be OK.
