    Vivotek cameras with OnVif movement detector (not working)

    Hi, I moved from Vivotek IP system (Vivotek cameras+Vivotek VMS free software) to a Dahua NVR, there is no possible with any Vivotek model to receive OnVif triggers about movements, it looks Vivotek uses a property protocol to work with its VMS only. Do you share this? There is any way to...

    How reduce HDD image disturbs, lines appear on video when HDD write, on Dahua XVR

    This time I've tried to instert an heavy inductance on the +12v of HDD line, with 100nF capacitors on on put and output, and also an 1000uF 16V capacitor on output, let's see. The 12V HDD is directly connected to the DVR 12V jack, that's also weird when the power supply charges a battery to...

    Does HiWatch/Hikvision support AoC from Dahua's cameras?

    Hi, I'm thinking to buy this technology to continue the client history (it has other Hivision's DVR) and I=m wondering to know if it supports the audio microphone coming from a Dahua camera such as HDW1231TLMQ-A-0280B, possible? And which mode this camera should work for that? CVI or TVI? I...

    How reduce HDD image disturbs, lines appear on video when HDD write, on Dahua XVR

    Your question is proper, no. I'm ground the shield of FTP cable only on the recorder side, on both sides 3 wires are joined for minus, 3 wires for plus, this eventually can result on loop, but I have examples where there are no clicks.. or very light ones, this as I say may vary from XVR...

    How reduce HDD image disturbs, lines appear on video when HDD write, on Dahua XVR

    Hi, I would discuss with you solutions ro reduce this annoying effect. Since I put the DVR on the same 12V of cameras (and it should be that, since I'm using a big battery 12V to keep system always on) on some cameras (depending on the leght of cable, model, and maybe some other factors) appear...

    NVR Dahua 4 detect face and open door on VTO

    to produce a short video on DMSS under the messages it's needed to rise an alarm (or video detection), maybe a face recogniction, I have no idea since I've never tested it, and I don't know if DMSS support the subscription on the face recognition. Maybe face recognition event is availabe on the...

    NVR Dahua 4 detect face and open door on VTO

    Thank you for clering it, in my case it's a problem because the client has any skill to proceed himself with adding (and more, do this on both VTO) and the place is far from me, I can't go there every time he needs to add or delete someone, simply no sense. More, during winter time it will be...

    NVR Dahua 4 detect face and open door on VTO

    Thank you for your kind reply, I agree with you that buying a didicated system, which does itself the work, which has a camera disigned for that purpuse, etc, it's alwyas the best choice in terms of reliability. But the cost does also have impact here, installing 2 of those VTOs in a different...

    NVR Dahua 4 detect face and open door on VTO

    Another important question, to create the white list, people have to register manually at each VTO? There is a way to share database between VTO? Can I do it remotely by web interface, for example sending VTO and image extracted from a video? My client is really hopeless with technology, he...
