I would open it, look up if there is battery on the motherboard, and replace it with a new one. Worth giving it a try.

You will need a computer with iVMS-4200, that way you can see on a single monitor all 16 cameras. You could also use some embedded device with Android. Or if a small screen suits you, just a tablet with iVMS-4500.

You can if on the new office you use a NVR instead of a DVR. With a NVR you could connect to the video streams of the DVR on the other office like if they are IP cameras. You need 4 cameras on the new office? Get a 8ch NVR with 4 IP cameras. Channels 1-4 will be the local IP cameras, chanel 5-8 will be the remote analog cameras on the remote DVR.

You can do it with iVMS-4200. If you mean from a web browser; no, there is no way to remember the settings.

Check out this one. Have fun trying to figure out what each cable in there does.

Use iVMS-4500, that's the app you are supposed to be using. I think iVMS-5060 is for chinese market.

From the web interface on a computer? When you click on the "record" button on the web interface you are actually telling the web browser to make a local copy on your computer. So, you will record on your local HD, not the HD you have installed on the NVR. If you have not configured a directory on the local computer, and you are not running the web browser with administrator rights, it will give you an error since it is not able to record.

Both are good units, and their specs are about the same. I have them and like them both. The only "pro" I can think that the 2CD2432 has is the IR led, while the Dahua has white led. It also has 3Mp sensor, but I use it at 2MP@25fps. If you are interested on push notifications, I would say go for the Dahua. Make sure you get the model you need (the one with POE does not have wifi).

Go for 24AWG. If it is not worth it to return the cable you got, well, just use it and try yourself.

For manual recording on E: drive you must run IE or Firefox with admin rights. Otherwise they are not allowed to write outside of some user specified folders, they are not allowed to write anywhere they please on your hard drivers. Right click on IE/Firefox shortcut, choose "run as administrator".

PSS is only for Dahua manufactured devices. So no, it will not work Geovision cameras. If Xvision are rebranded Dahua devices, it should work with them.

I would say go for HDCVI, 1080p (you also have 720p available, which will be a little bit cheaper). You will probably get the best quality for the price, and won't need to change all the cabling. If your coax is good, just replace the analog cameras for HDCVI cameras, and replace the computer for a HDCVI DVR.

Just turn off and on again the unit, the account will be unlocked. If you try to log in several times with incorrect password, it locks you out I think for 30 minutes. Ports are fine, the UDP port does not reply.

Mmmmh good point. I would have said if you are going to be viewing at all; but I just tried it now, and I can see video on Dahua without RTSP port forwarded. So I guess it sends video over TCP or UDP port. (with Hikvision and current firmwares I am sure that you don't get any video at all if RTSP port is not forwarded; I assumed it would be the same with Dahua)

You are missing port 554; you should be forwarding it too. It is used for RTSP (real time streaming protocol), if you do not open port 554 you will not get video. HTTP port is 84; I do not know why you are forwarding 84 to 86, but that should not make a difference. TCP and UDP ports are 37777 and 37778, you are also forwarding 37776, but again, that should not make a difference. To be on the safe side, you should make sure that you are forwarding all ports in both TCP and UDP. Once you have all needed ports forwarded (84, 554, 37777 and 37778) you can test that they are indeed forwarded and responding with a port scanner. You can try: http://www.canyouseeme.org/ If you get to the login screen but get a "connection failed" message from IE, make sure you have the needed activex installed.

You gain a 50% resolution increase

DDNS is faster when connecting. P2P is used for opening the connection; so we can connect to a unit that does not have forwarded ports. You need a server in the middle to do so. Once the connection is established, the data is sent from the DVR to you, it does not go through the server.

Glad you got it working!

No way to tell you what you are doing wrong if you do not say how you are trying to do it...

You are not doing it right. Of course you can. If you do not have the DDNS configured for hik-online, it will NOT let you register the device. As I said, it only allows you to register a serial number of a device that is ALREADY connected to hik-online. You can not just go and register any random serial number that might belong to someone else.

Push notifications work great with gDMSS and wifi, mobile, 3G, GPRS, or whatever I have tried.

Seen it before And yes, it is better not to use the admin account unless you really have a need to do so.

Again; check the DDNS section. The serial number does not belong to a device connected to hik-online.

Make sure that nothing is attempting to login all the time. Like, do you have PSS, DMSS; or any other software running somewhere? If you have it set up on a computer on the network, and you changed the password on the DVR, maybe as soon as you turn it on the software tries to connect with the old password, and oooops, user locked again. Also, you have two admin account by default. 888888/888888 and admin/admin. 888888 only works locally (monitor and mouse connected to the unit), admin can be used over network. If you messed up the "admin" account, you can use the "888888" account to change "admin" account's password.

That is a Dahua unit. It locks an account after 3 failed login attempts in a short period of time, you just need to wait I think 30 minutes. If the unit is near, just turn it off and on again. The account will be unlocked.
