NVR no ports issue

Hi, I’ve recently bought a Hikvision NVR with 16 channels on ebay (I know … I know… I shouldn’t have) and PoE Hikvision cameras from you guys. When I got the NVR I was a bit surprised to see that there is just a single LAN port (which I assume is to connect the NVR to router).

The tech specifications say htat it is a 16ch NVR. The problem is that the ebay seller is (I suspect) some chinese guy, as when I tried to contact the seller his response was quite unintelligible.

Anways, I can of course return the NVR and ask for refund, but I wondered if there was something that that I just don’t get?

What NVR model you have?

Typically, the number of ports that you have on the back of a PoE NVR is the same as the number of channels it can support. So if you have a 16-channel NVR, it would have 16 individual PoE ports to connect you cameras + another LAN port to connect your router. Check, for example, this one – DS-7616NI-K2/16P.

However, if you have a DS-7616NI-K2 model, then there is just one LAN interface on the back of the recorder but it can support up to 16 channels. NB! This model does not support PoE. So if you have PoE cameras you may need to get a PoE switch.

Thanks for htat

I have DS-7616NI-K2, I was under impression that this was a PoE model, but having just checked the specifications, it looks that it is not???

Is there any way I could 'upgrade' into PoE?

If not, do I just get a PoE switch and get it connected to a router?

Thank you in anticipation

No, this is not a PoE nvr and there is no way to upgrade it to one. That said, you can use use a poe switch for power supply to your cameras.

NIGHT VISION HELP
Discussion
Well, I've had some cameras up for a while but I've mostly used them just to see what's going on in front of the house from my office. I woke up this morning and saw that someone had broken into my car in the driveway. I thought I at least would have some good video. Well, in my opinion, the video was kind of bad. My initial thought is that my Blue Iris settings were just not tweaked properly (they aren't) and that I didn't have enough light. I have two cameras out front, both Hikvision, one bullet (DS-2CD2042WD-I) and one Turret (DS-2CD2342WD-I) The bullet sits about 20 feet up on the side of the driveway and the Turret sits right above the garage door.

Hi, I wondered if someone could help me with this. My partner and I have recently opened a small electronics shop. Within the shop there is also a small watch and jewellery repair counter, which the guy rents from us. The counter has its own shutters and is closed at nights. So the dilemma we have – the watchmaker guy is only interested in getting CCTV at night, because from his perspective, there is a very low risk of any damage done to his goods during a day (as he is always there). On the other hand, we are mostly interested in live monitoring CCTV during a day. There is also a bit of a debate as to who should have access to video footage. Anyway… long story short, we are looking for a system that would allow us to have live stream access for monitoring during a day and separate video recording at nights. The other difficulty is that the monitors that I would like to use for monitoring only support HDMI. They have a few more inputs but I don’t have a clue what they are – can take a photo of them if it helps though. Any suggestions would be greatly appreciated.

Burglar Alarm

Building a burglar alarm - electronics?
Discussion
I'm building my own alarm system with a DC alarm. What ways could i power an alarm and where should i keep the alarm so that the burglar can't just easily shut the power off to the alarm. Update: Chances are you're right William but I want to make it as secure as possible. Aggie I plan to use codes, but codes won't matter if the burglar can find the alarm and rip it apart. yes, frog man, I think you are onto something there. My alarm will be wireless so i think keeping the alarm outside the house is best, but that comes with its own wiring problems and such.
