No idea on how to do it from the WebGUI, I know how to do it from iVMS-4500, and I am sure it can also be done from iVMS-4200.

The technical name is "alarm" or "alarm inputs". Any IP camera with alarm inputs can be used with any kind of sensor, magnetic sensor, contacts, PIRs, etc.

That is correct, as long as you have scheduled your recordings to happen when there is movement/alarm triggered.

Of course.

Yes you can.

Main Stream (Normal) and Main Stream (Event) are the recording resolutions. You normally want to have them the same, but you could have (for example) your DVR recording 24/7 at a lower resolution/frame rate, and when there is an event (motion detection, alarm, etc) have it record at 1920x1080@25fps. When you log in remote from a computer you can also view the substream. When using the web interface, go to: Configuration -> Local configuration -> Stream type and choose Sub Stream.

1 - What you are looking for is iVMS-4500 for Android or iPhone. 2 - You can, but you would need to have IP camaras with alarm outputs.

North west from where...?

It will sound when you tell it to do so. You can configure an alarm output to trigger when there is movement on a given channel, when an alarm input triggers, activate it by hand from iVMS software, when there is an exception, etc...

They are surely great at spaming, I also get many emails from them.

Yes, he HAS to buy a new one if he wants full D1 on each channel, that's what I meant on my first post with "you need to upgrade the DVR". I did not mean a software upgrade, an update will do nothing.

I doubt that is a new unit. Firmware from 2 years ago... I do not remember the model name for the 1ch D1+7ch CIF models, but they have been discontinued for quite a long time.

It will depend on the bitrate being used on those channels.

I always use a gmail address with Dahua and Hikvision. It is only used for sending emails from DVRs, NVRs, IP cameras, etc, and I have no problem using it at all. Free and it will take you just a few minutes to set up, why not just make one?

Jpeg 2000 compression sucks. If you want more than a couple days worth of recordings, think about upgrading to a newer DVR with H264 compression, you will get way better quality and more days worth of storage. And once a unit fills up the HD.. it will stay full forever (or until you format the HD). Of course the "HD full" light will stay on, since it is full, the unit is overwriting the old recordings with the newer ones.

What unit do you have, what is the model? Your unit probably is 1ch D1 25fps and 7ch CIF 25fps; that means that channel 1 is D1@25fps and the rest of the channels are either CIF@25fps or D1@6fps. That is a hardware limitation, you will not solve it with a firmware upgrade. If you want D1@25fps on all the channels, you need to upgrade the DVR.

No idea of what MS AD DC is; but besides local user management, each Hikvision device also has its own users, and its own user managament.

Try it with your computer wired. Your internety speed won't make a difference on your network speed. Maybe using a network switch will, your router might also be the bottleneck.

LOL and they call it "mini microphone"? Have you seen the pictures? If they are correct, I am not sure I would call it "mini"... Edit: Take a look at the specs, it works with a AAA battery.

You seem to be on a windows for downloading recordings, and not for playing them back.

1) Your DVR needs to be hidden, do not just leave it on plain sight. 2) If you want to feel more secure; install 2 units. The real DVR hidden, the "fake" unit on plain sight. It can be a non working DVR, a crap DVR that doesn't even have a HD installed, and old unit, a deffective one, etc. Just make sure it seems real and is connected like a real DVR (powered on, with BNC cables oconnected, etc). If you get broken into, once the thiefs steal the fake DVR, they will not be looking for any other units.

I got it from the manufacturer. I really don't think they actually manufacture the unit, it is probably from some other factory, since I have seen these units sold by a few companies already. But they are the company that provided me the sample back at CPSE. They contacted me to ask if I liked the unit, I told them I was unable to use it at all, and they have been helping me troubleshoot some issues. I still think it is not a mature enough unit and I can still not call it "good", but now it is not "bad" also. I also did not get any useful manuals/software with the unit (everything on the included CD was in chinese). One thing I did think was that the unit at least would be great as a 4ch 1080p decoder. You just want to view 4 cameras 1080p on a VGA computer monitor? This would be a cheap way to do it, and hey, if it can also do recording on USB stick, that would be even better.

Yes, it is easier to do it from IE, you can just search for the extra stream recordings.

Well, you can actually playback the substream from PSS, you just can not search just main stream or substream recordings; you will get them all. I activated the extra stream recording yesterday on one of my cameras, and now when I search the recordings I have two recordings on each event. The bigger one is the main stream, the smallest one the extra stream. So we can playback the extra stream recording from PSS, but there is just no easy way for searching just the kind of recording you want, like there is on the web interface.

Configuration -> Local configuration -> Stream type, set it to Sub stream. Your internet connection probably does not have enough upload bandwidth to stream all cameras at the Main stream at the same time.
