I have seen Dahua HDCVI pinhole cameras, but only 720p; I think they do not have 1080p model.

That means that the device (IP camera, I guess) is not connected to hik-online, so you can not register it. You are only allowed to register devices currently online, so you are not able to register (by mistake or intentionally) a serial number that belongs to someone else. Is the camera turned on? Does it have internet connection at that moment? Is the network configured correctly on the camera? It needs IP, subnet mask, gateway, and DNS servers. Is the DDNS section on the camera configured correctly to use hik-online? Once the IP camera/serial number is registered with hik-online, you will be able to add the device.

What error message are you geting? I have no problems with hik-online, but I have not added any new device since before christmas.

If you can connect from iVMS-4200 to the NVR, you can download recordings to the laptop HD. There's no need to put a USB pendrive on the NVR.

Can you? Yes. Should you? Absolutely not. Bad idea. The IR will reflect on the front glass/plastic, so you will not see anything at night. You could of course remove the glass/plastic on front and move the camera forwards as much as you can, and it might work, if the IR does not hit the housing on the borders. Also, that housing looks like some crappy indoor housing. Why would you want to use it? To protect the camera from vandalism? If that worries you so much, get a camera with a better housing/bracket.

You can, and it is quite easy to do so if you have some basic networking knowledge. You just configure the network on your computer to be on the same subnet of the NVR, and you will be able to access the NVR from web browser or iVMS-4200. Like: NVR network - IP 192.168.1.200 / mask 255.255.255.0 / gateway 192.168.1.x Laptop - IP 192.168.1.any / mask 255.255.255.0 / gateway 192.168.1.x I think you might not even know iVMS-4200 is? iVMS-4200 is a program you run on your laptop; it is not the software on your NVR. So it doesn't make sense that you say you are using iVMS-4200, and using the USB port on the NVR. Either that, or you have not even looked how iVMS-4200 works, since of course it does allow you to playback recordings from the NVR, and download recordings on the laptop HD. Without the need to use the USB ports on the NVR.

That's it.

What? The question is? Are you trying to use it with some wifi USB dongle? It's not going to work. This is not a computer; it would need drivers to work with some random wifi USB dongle, and it doesn't have them.

666666 account can be deleted, I do so almost on almost every Dahua unit we install. I never tried deleting 888888 and admin, but I do change the passwords.

And what did you actually expect? You do have more resolution. WHere you have 704x576, now you have 960x576. Did you think that changing the DVR would make your camera see wider? The DVR just turns the analog video signal it receives from the camera into 0s and 1s. You do have more resolution now, so you have more detail. But changing the DVR won't change the angle the camera is seeing.

Those are accounts for a Dahua unit. "888888" account can only be used locally. That is, pluging in a mouse and monitor on the DVR/NVR. It can not be used remotely, so even if he knows the password (by default it is 888888) he could not use it unless he is phisically on the same place as the recorder. This account can not be deleted. "default" account does nothing. It comes out on the web interface, but it is just a system account. Do not worry about that. I do not know if it can be deleted, I have never tried. Then there are two more accounts that come by default on Dahua units. "admin/admin" and "666666/666666". "666666" account is a visitor account, it can see and playback cameras, but it can not touch the configuration. "admin" account is the one you should have the password to, and change it if you feel like it.

Then talk to him. I don't find it so creepy, but it would be if he wants to keep access to the device. We always change the default admin password, and give it to the customer. On the documentation we give it we advise them to change it to something else; and also warn them that if they do lose admin access to the device, it will be their fault, and they will be charged for access recovery. But any unit we install, it is the customers unit. He can do with it as he pleases, and we do not connect to the units after installations unless the customer asks us to do it for whatever reason.

Change the admin password on the device. Remove any other accounts.

iDMSS does not. You can take a screenshot or record some video at a given moment. But it is not working 24/7 recording from your cameras, it wouldn't make much sense to record on a mobile phone (very little storage, battery operated, limited bandwidth). You can use a PC as a NVR. I think Dahua might have free software to do so, but I do not know which one it would be. Maybe Smart PSS can do it? And I am sure many people here can tell you better options, some free, some commercial.

iDMSS does not record, unless you do it manually like you say. If you want to playback from the cameras, you will have to put a memory card on each camera (if they have a memory card slot), or you will need a NVR to record the cameras. Well... If you do not have anything that records, it would be quite weird if you did get to playback anything.

Try this. No iodea if it works at all, I do not use Mac. http://www.hikvisioneurope.com/portal/index.php?dir=Software/02%20%20%20Web%20Components/ You can always use iVMS-4200 for Mac.

Awesome. Last time I tried this it did not work, but it has been a while.

And is EZVIZ actually enabled on the camera...?

My cameras are working at 1920x1080, my screenshots are at 760x576. DS-7716NI-ST v3.1.5 firmware. On the dropdown I have automatic (which I guess would be the same resolution as the main stream?), 704x576, 352x288 and 176x144.

You can change the screenshot resolution on the NVR, and I am quite sure also on the camera. But that will just change the resolution of the screenshots when the NVR/camera emails you with a screenshot. That "Cammy" app you are using (never used it) probably gets the screenshot from your camera/NVR main stream. So, it probably just connects to the video feed, and gets 1fps. If that is the case, whatever resolution you set on the camera/NVR screenshot will not make a difference. If the app gets the 1fps from the main stream, whatever resolution you set your main stream to, that will be what Cammy gets.

It does not look like one. It seems to be just a standard PIR sensor.

That's the way it works with this camera. When the camera turns on the IR leds turn on for a while.

Wow, I didn't even know this existed. Network signal over coax, and also POE? Awesome, I will remember if I ever need this.

Well... Not there indeed. I don't have any DS-71xxNI to check, but my guess is that it just doesn't support it.

Post a screenshot of the section. That is the entry level NVR, so that option might have been removed.
