That many cameras with NO VIDEO, that probably means that a power supply has died somewhere. Find out what is (was) powering the cameras that have gone black, and you will probably find the problem.

Two weeks and you want to go for HDSDI...? I am sure that if you poll the forum between IP, HDCVI, HDTVI, and HDSDI, HDSDI will be the last option. In fact, probably noone will recommend you HDSDI.

Control panel -> System configuration -> Image -> Auto change video stream If you leave it checked, iVMS-4200 will show you the substream of a camera when you are watching many video feeds, and when you double click the camera to make it full screen it will change to the main stream. If you leave it unchecked, then on the main view you will be able to choose what stream you want to watch. Just right click on a channel, choose the stream you want, and then drag it to an empty window.

Use Hikvision's SADP tool, which is what you should have been doing from the start...

Why stop at 16 cameras? Why not flash it for 32, 64, or just unlimited cameras? Profit!

Check this out: http://www.hikvisioneurope.com/portal/index.php?dir=Integration%20and%20Development%20Materials/00%20%20%20CGI/ Take a look at "HIKVISION CGI IPMD V1.5.9.pdf" (IPMD = IP Media Device Management Protocol). Page 76 is what you are referring to. I used to have this working, but I just tried with our 7208HWI-SH and doesn't seem to work. RTSP should be working. You might want to make a program that connects with RTSP to the devices every 30 minutes, and gets a screenshot fromi the RTSP stream.

You do need a PC or a tablet. A tablet would be the best option, having a computer turned on 24/7 jutst to see who is at the other side of the door wouldn't make much sense.

I don't see Dahua reseller in my and border's country. I see local company, which is rebranding it and sell it 4x expensive... It is not normal situation. Then if there are no resellers, how do you expect to get any support...?

You should be buying from a european source that gives you support.

The NVR is not saving the recorded video on your desktop PC; your desktop PC is saving the video on your desktop PC. The NVR does not have any access to your computer hard drive, it is IMPOSSIBLE for it to save anything at all on your computer hard drive. If you are geting videos saved on your computer hard drive, you are either geting them because you have installed iVMS-4200 and told him to do so, or because you are recording them yourself from the NVR's web interface. What you say that the NVR records on your computer hard drive just can not be happening. If you do not have any recording on your NVR's hard drives is because you have not configured recording right.

Will try it with Wireshark. Do you happen to know what is the default user/password for AVTech?

Go to: Camera settings -> Schedule (I think that is the name, I have it in spanish). Do you have recording enabled for your cameras? Have you set up any schedules, so they record 24/7, they record on motion, or whatever? (well, we do know what the answer is, right? )

I don't meen to be rude, but this is clearly a case of PBKAC. On the configuration tab you have plenty of things to configure. You have local config, which might (or might not) be where you are now, and you have remote config. I would bother on making screenshots and posting them, but I really won't do so if you don't even bother to post screenshots youself so we can point you in the right way.

It is possible. You can use the NVR without a monitor. You can configure everything without the need of a monitor and mouse, if you know how to do it, which seems is not the case... Everything that can be set up on the NVR itself can also be set up through the web interface on the configuration tab.

You should really take a look at the manual of your NVR to see how to configure the unit... Maybe try to hook it up to a monitor, and use it with a mouse? You are really confusing how to use the NVR, and how to record locally on a computer, so it might be good for you to remote the computer from the equation. Or post snapshots on what you are doing, and how, so we can get a laugh at you, but hopefully get you on the right track too

EZVIZ does not record on dropbox or anything like that.

The camera name is on the camera, not on the NVR. So until you have actually conencted a camera, there is nothing to rename.

Just wondering, but as you say, Sannce only has english manuals. So if you want a professional translation, maybe you should hire someone to translate the manual for you? Otherwise you will have to do with any automated translation method you can use.

What is your upload speed, and what is the bitrate on the video feed you are trying to watch? That is probably the answer to your problem.

Is it working with a mobile connection? If so, you might have used all your available data for may. Maybe tomorrow with the new month the speed is good again.

You might also want to try iVMS-4200 for Linux. http://www.hikvision.com/europe/download_more.asp?id=1327

Ask yourself first what working time do I want for that mini IP cam? The smallest battery is no battery at all, which will give you 0 minutes working time . From that on, you would need to know what is the minimum working time you expect, and given the mA that your camera uses (which you will have to check) see what is the minimum battery you can use.

I can't think of a reason why you would want to use anything better than copper Cat6 at the moment, and in most cases you do not even need/want that. But if you don't mind the price, surely you can use Cat7.

Lease it at 90/10554/8080, that is nice. And then when you try to access with web browser from your local network add the web port at the end, http://192.168.1.138:90 How are you configuring iVMS-4500 to access from outside the network? Do you have fixed IP address? Or by chance you are trying to use the internal IP, 192.168.1.138? If you do not have fixed IP, configure DDNS like the following: - Enable DDNS: checked - DDNS: provider HiDDNS - Server address: www.hik-online.com - Domain: whatever_name_ you_want_to_use Then for accessing from outside your network you will be using: http://www.hik-online.com/whatever_name_ you_want_to_use And on iVMS-4500, your device config: - Register mode: HiDDNS - Server: www.hik-online.com - Device name: whatever_name_ you_want_to_use etc
