@bluegene, No, you need only 1pc! This is a 4x2 distributor (you also have 8x2, 16x2...). You would feed camera 1 on input 1, the one on the left. This input is then duplicated, it has 2 outputs beneath. Output 1 would go to DVR 1, output 2 would go to DVR 2. The same would be done for each of the 4 cameras you want to record on 2 different DVRs.

I can not think of any reason why if the DVR with 3G router is configured properly, it would work from another 3G connection and not from any other kind of connection. If you have the right IP and open ports, it should not matter from what kind of connection you are trying to connect from... What router do you use?

Is anyone around here using the free dyndns service for Hikvision DVRs, hik-online.com? I have tried it and it is working fine when accessing from a computer browser, but I am unable to get it working when using IVMS4500 (Android, iPhone, etc). I have no idea on how to set up the device on IVMS4500 (also on 4000 and 4200).

If your current DVR has loop outs (one video output for each input channel), that would be trivial, you just feed the loop outs to another DVR. Since you are asking, it would be obvious that it does not have loop out. You would need a 4x2 video distributor (4 inputs, 2 outputs from each input), something like the following. You will input the 4 cameras on the video distributor, and from the outputs take 4 cables to the current DVR and 4 cables to the new unit. http://www.securame.com/video-distributor-2x4ch-bnc-distribuidor-de-video-c0408-p-967.html

This seems to be just a cheap camera problem, and has nothing to do with your DVR. If you connect the camera direct to a TV, how do you see it? If you see it the same way, the problem is the camera. It looks like an infrared camera with no IR filter, so the colors will not be right.

That is just the min/max bitrates you can configure, since they have different resolutions they probably also have different bitrates by default. Cranking up the bitrate all the way up with no reason probably will not give a lot better quality, but it will surely take up a lot more HDD when recording.

You mean GDMSS and so on?

yes you can. dahua have just put new remote software on to there FTP site. you now have more control over brightness .... recording ..... and alarm / relay switching Hi Tom, Please tell us more! What software, where? PC or mobile? Thanks!

Hikvision has its own DDNS service, and I am 99% that Dahua also does. You really do not need to pay for a fixed IP or for dyndns account if you do not want to, I have also seen many chinese brand DVR with a dynamic DNS service, but I wouldn't trust them too much.

If you don't have a static IP, then you need to use one of the available dynamic DNS services, any will do. You should be able to do it already using your direct IP, which you can find out here: http://www.whatismyip.com/ (but this will only work as long as your IP is not change by your internet service provider; that is why you need a dynamic DNS service, either that or you have to pay to have a fixed IP).

Your problem seems to be with the DVR, not the cameras, if you are geting a nice live image, then the cameras are doing fine. Really strange that it needs to have movement on 6 "blocks" before it triggers, but it does seem quite a crappy DVR, and also quite strange if you say it has happened to you with two different units. You should not even need to touch any of the motion detection settings on the cameras OSD for that.

You need to forward 3 ports with Dahua DVR. Web port (80), TCP port (37777) and UDP port (37778). Then you weill need to either have fixed IP, or configure a dynamic DNS service like dyndns or no-ip (I am not going to explain that since there are plenty of guides and tutorials available).

Maybe I didn't pick the right words with "I am quite sure WD would not approve that description". Just go ahead and feel free to try. There are many kinds of "DVR enviroments", if you think that "DVR enviroment" might cover recording 4 CIF streams with motion detection and at the same time might cover recording 16 D1 streams 24/7, just give it a shot in your given setup.

Lionko, Wow... Just with the login screen I can tell you that it does not support RTSP; I would go as far as to say that it does not even support IVMS 4500, so you can not even see it from iPhone, Android, and so on. That is quite an old camera, the model is DS2CD892P-IR. Btw, I would advise you to edit your post and remove the IP, or to change your admin password to something different than the default.

Your camera has a CCD 1/3" inch in size, so you need a lens for 1/3". Anyway I don't think you will find 1/4" lenses any more, since 1/3" lens work on 1/3" and 1/4" sensors.

I had about two years ago a pain in the ass customer that got a 4 camera system installed. He was a cheap guy, so he thought that the price we were giving him for a 1Tb HD was way too high (it was a WD blue; I quoted the price we pay for it +20EUR for installing on the DVR, formating, and configuring the DVR, we only have to cross the street to but the HD). So he asked if he could bring his own HD, we said sure. He purchased somewhere a 1Tb external HD, ripped the enclosure case, and brought us the HD so we would install it for him free of charge (fine, after all, he was buying everything else). It was a 1Tb WD green, and he was even telling us how much cheaper he had bought it for. He got his 4 channel D1 25fps set up up and running, and we didn't hear from him in about 4-5 months. So he comes back with the DVR under his arm, his unit was beeping all the time. We check it, the DVR is fine but the HD is dead (the DVR was complaining, "HD failure"). So since he had not purchased the HD from us, I told him that he was on his own to get it repaired. I told him quickly how to remove/install a new HD, and he left. And a few months later, he comes back yet again with a beeping unit, and of course the same problem. No idea if he got the HD replaced the time before (I doubt it, he bought an external HD and destroyed the external case) or bought a new one, but he had again a non working HD, and again a WD green unit. He told us that maybe DVR was defective and was killing the HDs. I checked the DVR settings, and found out that he had reprogrammed the unit to record not just on event/movement, but 24h continuous recording an all 4 cameras. This is when I explained to him that there were different HDs. And that he had purchased a WD green USB external disk, which was supposed to be used maybe for backups, movies storage, whatever, and had it installed it on a DVR powered 24h/day; and not only that, he also had reconfigured the DVR so that the HD would be recording non stop until the drive died. He then understood why the HD we were selling him the first time was a little bit more expensive, bought a second (or third) HD from us, and left our shop for the last time (of course I also charged him one hour for all the hassles fixing his mess, and testing his non working HDs). That is I think the last time I have seen a WD green on a DVR. I am not saying they can not work with certain DVRs, and under certain configurations, but with the small price difference with blue units, I think it is not even worth trying.

Well, Western Digital manufactures those hard drives, and not NewEgg, and I am quite sure WD would not approve that description.

That is a WD green drive. I would also advice to stay away from them for CCTV and standalone DVRs, from WD we only use blue, red and black, price difference between green and blue is so small that it is just not worth it. Which one will depend on the DVR and how it will be working (depending the number of cameras, resolution, FPS and Mbps, recording 24h or motion, etc).

Your boss has watched way too many 007 movies. I second this.

192.168.0.10 and 192.168.1.1 are on different subnets, that will never work with mask 255.255.255.0 (and I am sure you have set up one of those numbers wrong). If your router IP is 192.168.0.1 your DVR IP should be 192.168.0.10. If your router IP is 192.168.1.1 your DVR IP should be 192.168.1.10.

Wow, that seems one very expensive camera at $170 given the specs... 450TVL, 3 lux, and they dare to call it "low light"??

Don't do it. You will lose the warranty on the camera (in case you have any, since you purchased from China), you will lose some options on the camera (in case you ever want to use it somewhere else; or want to resell the camera if you ever upgrade), and some of the cables might shortcircuit and make the camera work erratically or not work at all. Use a junction box.

Is it an amplified mic? Your problem might be due to a bad quality mic. You have to make sure you enable audio on your streams on the cameras you want to have audio. You can enable it on main stream, extra stream, or both. On live play I think you will get audio even if you are not recording it, but of course if you want to have audio on playback, you have to record it.

It is indeed, since Dyn.com went "payment only" now it is a great option to use hik-online.com with all DVR devices.

Googling hik-online I found this thread which I started myself over half year ago. Since then Hikvision has updated all their softwares (iVMS-4200 for PC and Mac, iVMS-4500 for smartphones, and iVMS-4500 HD for tablets) and now it is possible to connect a hik-online DVR, NVR, IP camera, etc. from web browser and any client. I wrote two posts on our blog explaining how to configure and use it, they are in spanish but hopefully they will help someone. http://www.securamente.com/como-utilizar-el-dns-dinamico-hik-online-com-con-tu-grabador-hikvision/ http://www.securamente.com/como-conectar-a-un-equipo-usando-hik-online-y-cliente-ivms/ Everything that can be done with hik-online.com can also be done with hikvisioneurope.net, in fact I think euro costumers should be using hikvisioneurope.net now, but since I started using hik-online before they had hikvisioneurope.net I am sticking with it just so I do not need to reconfigure all my machines.
