Question: Is the camera supposed to come with a power cord if not where can I get one
Document: This was my first surveillance camera purchase and I have been happy with it. With the 4mm lens I monitor a shop next to my house. The camera is attached to one of the awnings on the house roof, and I have run an Ethernet cable through the attic to a computer in a bedroom. The camera is powered using a 48 volt, power over ethernet injector on the data cable (or optionally 12 volt "wall wart").
For the price this is probably the best IP Camera available. Has 1080P streaming, IR illuminators, IP66 water proofing and feels solidly built. I use 5 of these in an installation of 30 IP cameras and can say with confidence these are among the best. The image does get washed out at night due to reflection of the IR light on the round dome and if night vision is of great concern would recommend the Hivision Bullet or Elixir model instead.
Earlier review was about the wrong camera, so I deleted it. just got the camera shown and connected to my network, run the camera finder program found camera, but could not get it to install web component for internet explorer 11 in windows 7 pro.just as previous reviewer indicated. Had to add camera address to browser compatibly view setting, then every thing worked after that. other than that the camera is fine . Perfect for home installation, not big and bulky.
will see if this one display the same night time view. the other camera is identified  as NC-KD032, so I suspect this is one of those  OEM brand.
It would have been better to have it set to DHCP by default. It works well with Blue Iris and has been very stable.This 4mm one is perfect for my front door. I should have gotten a wider angle version for the side and rear where a wider field of view would be helpful and it's not necessary to also have a good view of the street.
I have the similar bullet version (DS-2CD2032-I) out in my front yard where there is other nighttime lighting, and I LOVE it. This one, however, isn't working nearly as well. I don't think the picture is as clear, and the IR lights up bugs so bright that they are constantly triggering the motion recording. As in about once a minute during the night, taking up a lot of recording space.
I tried several different 1080p POE cameras, and this was one of the best - and a bonus was that it was also one of the cheapest.The picture is very clear both day and night. The IR is good enough not to wash out people close by, and there's dynamic range compression so backlit people's faces are not just blank shadows.The included web interface is easy to navigate and full of features.
Your browser needs a driver to view the current scene. They only have drivers for windows or Mac systems, but nothing for linux. I did find an Android app that works for a monitor but can't do the setup. I finally did the setup (IP address, motion filter, etc) in windows.So if you use anything linux I'd be wary of buying one of these, or any Hikvision camera's including the rebranded names.
I have purchased four of these cameras and they work very well. The night vision is not the greatest for a camera in this price range but the quality and reliability are very good.
I read a little about the format difference, and it sounds like the H.264 format saves on network bandwidth, which is important since this is 3 megapixel camera. I think that the higher resolution of this camera is worth the price differential over the 640x480 cameras.
Answer: The camera is PoE and uses power from a PoE enabled switch, or one of Hiikvisions NVR's. You could get an injector if need be and install it inline with the cat 5/6 wire run to the camera. Hope that helps.
