As another option, if you don't want to mess with PoE midspans, you can just power the cameras with standard PSUs.

Hey, Welcome to this exciting world of CCTV. I think, as a minimum, you should also think of getting an HDD and brackets (depending on how you intend to get it mounted). Otherwise, I think you are good to go.

Do you have any more leftovers?

Yep! Just like this

Did the HDMI solution work for you?

@Armsec Hi Armsec, I wondered if you could me with the query I have. I have a number of Hikvision DS-2CD2123G0-I(S) cameras in my office, from your post I understand that the prefix S means that they should record audio as well but they don't. I bought the recorder for these cameras from you but the cameras from eBay. I tried to contact the buyer but could not get any adequate response to whether the camera can record audio. i've read somewhere that I need to activate the audio but is that on the NVR or cameras themselves? Wondered if you could help. Many thanks in advance.

@xerob Many thanks for that - I've jsut double-checked the cameras I have say DS-2CD2123G0-I(S). Does that mean that they support audio?

@xerob I am using 9x Hikvision - DS-2CD2123G0-I

Hi, I have a 16PoE Hikvision NVR which is supposed to support audio but I can't get any audio - all playbacks are mute. If someone could point my in the right direction that would be much appreciated.

That looks like a lot of work to do!? Can you recommend any cooling fans to swap the standard Hikvision ones?
