This is from Finnish importer/distributor of Dahua.Who or where did you buy the camera ?
Yes, I know, I have good communication with the distributor and we are trying to figure this out together.You will have the Full Support of Dahua. I would contact your distributor again and ask for support if they can not help tell them it is being returned for a full refund and find another Distributor.
Actually the injector should be fine. I just got report from the dealer that he has tested similar camera + injector combo and had similar results.Hi oh6hfx, glad to hear you have fixed the problem with the reboots and time to RMA the Dahua Injector.
Please read the whole chain and just my last message: "I just got report from the dealer that he has tested similar camera + injector combo and had similar results. "Your camera SD5A225XA-HNR works of 5W no IR and 20W with IR so should be well enough to run your camera. With what you have stated I would be returning this camera to your supplier.
Yes, that's what I've been thinking also. It must be that these 25x and 45x HNR models have something which makes them reboot on PoE power."If" all the camera's are rebooting on different Switches no matter what make model then a problem lies with that camera model. I doubt that the dahua Spec sheet will be wrong but even if so look at other models in that range they all take around the same power a 30W rated switch would be more than enough even if it is really 32w or 26w. The switch I recommended is 30w on each port with a total 67W over 4 ports.
What I can't understand is why your dealer tested a similar model that would be pointless surely! it would need to be the same model that you are having problems with.
I have similar problems whit this cam too. My client use it with NVR4208-8P-4KS2. Camera shut down or freeze during autotracking and not boot up very well. I already change the new cable and conectors and still no help.Please read the whole chain and just my last message: "I just got report from the dealer that he has tested similar camera + injector combo and had similar results.

My client has several (near 10) of these cameras and all of them have reboot issues with PoE power. Some several times a day, some once a month. He even has one camera plugged in Dahua 90W
switch and still has several reboots / day. I can't believe that every single of those cameras would be defect.
It seems that camera acts slightly different with different switches. 30W is not necessarily 30W in those Poe+ devices, it can be also 26W or 32W. Can be also that in Dahua spec sheet is wrong, and in
specific circumstances the current draw is more (camera is ir on, tracking, zooming, panning, tilting and focusing same time).
Did you get this solved with 75W injector?I have similar problems whit this cam too. My client use it with NVR4208-8P-4KS2. Camera shut down or freeze during autotracking and not boot up very well. I already change the new cable and conectors and still no help.
Well, that is one option. Just trying to find the solution for my client. I personally would just put AC24V power supplies and be happy with that. But if they want to use PoE, it seems to be hard with these models..Sounds a right pain in the ass what you are going through and If you have followed the manufactures instructions on power needs ( Which you have ) and still having problems then I would definitely be doing a RMA on the camera or camera's stating that they are not fit for purpose.
