As port 80 is set for the DVR's ddns and port 80 is shown as a https port, do you think we need 443? Have tried resetting the hub, setting a 5th rulling to over lap 443 whitch the hub rejects as already in use by my hikvision device, still will not clear the port checker.

had to reset the DVR

Have been using a ddns/no-ip link to view our cctv for about two years, after a reson reset the mobil phones still sign in and see the cameras screens but time out before showing a video. How is this remidied?

Bing-go Our only grip, is why Hikvision does not have this information in it’s manuals Thank you

Before we ge too deeply into this, can I correct the first line of your reply, “Not at all - you shouldn't need either for a conventional alarm.” it is not a conventional alarm. It is tailored made, and triggered by the timer showed a few massages back. That is why I asked/suggested a RS485...

Our DVR was set to your instructions above apart from changing the NO to NC box, we have rectified this but when the line crossing is triggered it still only sounds the alarm in the DVR without triggering our independent alarm system. Which to me indicates we need a RS485 itrface or relay...

Will you please send me a link to a manual that describes the in out warning feeds, for our DVR. As all we want is a between 3 to 15v signal from the DVR, to trigger our independent alarm system.

This to me suggests that this DVR is not up to doing what we want it to do. The biggest gripe I have, is that it shows our Alarm warning in and out box at number 13 on the back view of the DVR, but no manual we have been abel to find has any instructions on its use. Time I think to look at...

We are getting a 4.7v suppy from the DS-2708HUHI-K2/P DVR'S without putting any external supply in, which does not trigger the timer, yet 3 x 1.5v batteries will. Would the 4.7v supply feed a 3.3v reylay, to work the timer?

I would still like to know if the DVR generates it own low voltage output, as I do not want to damage anything by introducing an outside 12v supply to the ‘in’ alarm port on the back of the DVR?

Thank you for your reply, I will explain what I am trying to achieve. I could use "line crossing" in place of "motion detection", and when say rule 1 is crossed it triggers alarm ports one in and one out on the DVR with a 'N' feed from an outside 12v supply for say 5 seconds. Rule 2, doing the...

As in the title, DS-7208HUHI-K2/P

Does the DVR use its own low voltage supply when a motion warning is triggered, asking this before connecting an outside 12v supply to the alarm in plug on the back of the DVR. Also how do you separate a second alarm warning on the same screen?

Many thanks for your help, with it I could perhaps adopte my Dyslexic age of 19 for technology.

Not sure I have done this correct, unticked the box and edited the address on the DVR screen. This stoped the bleeping and got rid of the triangle, then ping and got this result

Sorry about the delays in answering, have elderly wife with Dementa which takes up most of my time. Have not used SADP before, it opens up to the not very good screen shot with no link to Share result table. Entered admin password and pressed modify, which is all I cand find to do and get...

First two apologias: it is a DVR not NVR, and for the delay in replying. The invoice list it as a 8DVRHKD2TB, the box has DS-7200. purchased 2018. Yes my PC has SAPD installed.

We recently had a power cut, when the NVR rebooted the NVR was beeping and we had an error message on the live view that said "IP Conflicted". What is the problem and how do I fix it?
