The voltage would drop by the time it reaches the camera. You would need to use passive splitters on both ends which is a mess....no need for a silly 12v ups...Thank you so much for the quick response !
I was just wondering if the camera takes direct 12v input why wouldn't it work with 12v over the Ethernet as the voltage at the camera will be very close to 12v and this makes it easier to use a 12v UPS with it.
Thanks again for your response.
no it does not work well. You do know that they sell standard regular UPS's for your 230v. But you seem to know better, so screw around with this backwards setup, then create a post complaining that your camera freezes, drops offline etc..Thanks fenderman for your response.
But where I live we have regular power cutouts.
Sometimes there is no power for hours so using a dc ups greatly extends the camera uptime.
Edit:and I think the voltage drop will be very minimal.
However,you gave me a very good idea (using splitters on both ends). Does this work ?
you are confused, you dont need a 48v ups...you need the SAME type of ups you would use for your computer or NVR.thank you for your continued assistance fenderman.
You are right about the regular ups’s but the problems with them are the size,cost and efficiency.
They are more than 10 times larger than the 12v ups’s but they are much less efficient,especially at these low voltages.
However I will take your advice and avoid the splitters and will try to look for 48v ups’s.
There are 24v ups’s mainly for wireless networks but I haven’t seen 48v ones.
Again thank you for your assistance,much appreciated.
buy an 802 poe switch they are cheap. start reading about how poe works, you are confused.I bought only the camera which didn’t come with a power supply,and I have a passive Poe injector that I want to use with the camera with a 48v power source.
And I don’t have an NVR,I intend to connect the camera with my WiFi router and use it from my phone.
I don’t intend to record the video and all my network have their continuous power sources(they all work on 5v)
So only the camera needs a continuous power source.
There are passive midspans and injectors, you dont explain what you are using and what you are trying to do...just get an active poe injector and forget about this crap...nice, clean, reliable.Thanks again for your response.
As I understand the 802.3af standard delivers 48v to the camera.
So wouldn’t a passive poe injector with a 48v power supply deliver the same power ?
Please correct me if I am wrong in this assumption.
I am just using a simple passive Poe injector like this one:There are passive midspans and injectors, you dont explain what you are using and what you are trying to do...just get an active poe injector and forget about this crap...nice, clean, reliable.
stop it...I am just using a simple passive Poe injector like this one:

If I use it with a 48v power supply would it work?
Anyway I will do more research about this.
Thanks again for your assistance!
What is the difference between passive and active Poe if you supply the same voltage ?Passive PoE sucks. Do yourself a favor and avoid it.
I'm not overly fond of calling it active poe.What is the difference between passive and active Poe if you supply the same voltage ?
