Hello everyone and thanks in advance to anyone who can give me a hand, I saw that there are new models of Dahua panoramic and PTZ cameras, now I would be interested in purchasing this model but unfortunately I can't understand the type of power supply either from the review or from the technical sheet, the model is Dahua DH-SDT6C432-4P-GB-APV-0280, Does anyone know if the power supply supports Poe, Poe + or something like that instead of its mains power supply?
 
Sembra solo 36 V CC 2,23 A, perché non ho visto nulla che menzionasse POE nella sezione "Alimentazione" della scheda tecnica. Non è un alimentatore comune, quindi immagino che lo forniscano con la telecamera.
Thank you very much, I had read this too, the power supply will surely be included also because I already have a PTZ and there was a power supply in the box even if the PoE system worked, I don't understand how it is possible to make a security camera without this requirement with the cost it has?? or is there some other way?
 
Not many here would recommend that camera as it is not on the ideal MP/sensor ratio, which is critical for a PTZ at night.

Here is where someone got one and commented how poor it is at night.

Really??? almost a thousand euros and it has all these problems? I don't support PoE and poor night vision, but let's say I could do without it, mine is a lit area but I don't need to have a coorent cable so only Poe power...
 
I still don't understand this policy on certain products, not even the least powerful model has Poe power supply... none of the DH-SDT6C425-4P-GB-APV-0280 and neither DH-SDT6C435-4P-GB-APV-0280. A REAL SHAME
 
Is this one any cheaper?

While suffering from the same MP/sensor issue, this one is marketed as POE.

Sold by trusted vendor here.

I am not 100% that is correct, I got a camera on my bench that don't have any poe info on the labels for the camera and the owner gave me a 75w poe injector, right now have it connected with my bench power supply but it only shows 24-48dc on wire and labels on body says 36vdc, oddly it is changing voltages and even with my power supply max current as per labels it does go into a constant current mode from time to time. I have not tested yet with poe injector seeing there is no poe info on the camera or in the datasheet, thought I would bench test with rated voltage before trying poe. Thought maybe not offered because this is very big PTZ with wiper and all the trimmings. Figured I would test 36vdc maybe I get lucky but no camera firmware dead. This is a beast will have to make mount to repair...

Funny don't recommend camera because of sensor size but it's ok from trusted vendor love it....

By the way my old Amcrest 858ew from 2018 wasn't listed as poe+ but it also works with POE+ just saying..

I recommended it simply because it is powered by POE which was a concern of the OP, but meets the other specs he seemed OK with including less than ideal sensor size, including cheaper than he was looking at.

I do not recommend the camera otherwise as shown in other posts, including the one I linked above that said it sucks at night...

It was simply being pointed out there is basically a POE version of the less than idea camera specs he is looking at at a cheaper cost.

I don't care if it's cheap but if it costs almost a thousand euros and I can't use PoE power, it doesn't make sense
 
That is why I suggested one that is marketed as POE power, or take the chance with the one you are looking at and see if it will work with POE.

Regardless, the pano/PTZs on the market seems to be on less than ideal MP/sensor ratios and most here would suggest different cameras. I'd rather have one great functioning PTZ than a gimmick one that doesn't meet my needs at night.

oh wow? can you tell me what model it is? and then could you try using a poe injector to see if it works?

you're right but I just have to replace a ptz that I already have to be able to expand the system so if it's less performing it doesn't matter because in any case it becomes two! Who sees better than one? Two!
 
Non sono sicuro al 100% che sia corretto, ho una telecamera sul mio banco da lavoro che non ha alcuna informazione PoE sulle etichette e il proprietario mi ha dato un iniettore PoE da 75 W. Al momento l'ho collegato all'alimentatore del mio banco da lavoro, ma mostra solo 24-48 cc sul cavo e l'etichetta sul corpo dice 36 cc. Stranamente cambia tensione e anche con la corrente massima del mio alimentatore come da etichette, di tanto in tanto entra in modalità a corrente costante. Non ho ancora testato con l'iniettore PoE visto che non ci sono informazioni PoE sulla telecamera o nella scheda tecnica, ho pensato di testare sul banco con la tensione nominale prima di provare PoE. Ho pensato che forse non sarebbe stato offerto perché questa è una PTZ molto grande con tergicristallo e tutti i fronzoli. Ho pensato di testare 36 cc, forse sarò fortunato, ma nessun firmware della telecamera è morto. Questa è una bestia, dovrò costruire un supporto per ripararla...

Divertente, non consiglio la fotocamera a causa delle dimensioni del sensore, ma è ok, il venditore è affidabile e la adoro...

A proposito, il mio vecchio Amcrest 858ew del 2018 non era elencato come PoE+, ma funziona anche con PoE+, tanto per dire...
Quindi sai anche riparare telecamere? Lo chiedo solo perché ho un problema con un PTZ di cui ho già parlato in questo mio post... Problema con Dahua ptz ip, ma non conosco il nome del difetto, aiuto, grazie
 
So yes using the 75w poe injector the ptz does the dance just the same as it did when I connected with my bench power supply.

So funny thing is now looking at this cameras datasheet it now states 36vdc 2.23A +-25%, Hi Poe. Where before looking up datasheet awhile back there was nothing about POE and as pictures show not on label on camera. Geez so confusing lol.

in fact, in the technical sheet it says that it is compatible with Hi PoE.. Do you think the same thing could happen with this SDT6C432-4P-GB-APV-0280?
