It can be done, you will need a router that supports your USB stick. For how long will it last? That depends on what video streams you will be viewing (it is not the same to watch a camera at 1920x1080@25fps, than to watch a camera at 176x144@6fps), and how often you will be watching those cameras. If you only take a peek once a day, it will last more than a week. If you will be watching non stop, 4Gb might not even last for a day. I have used sometimes this TP-Link router with success: http://www.tp-link.com/en/products/details/?categoryid=&model=TL-MR3020

The player needed depends on the standalone DVR that was used to do the recording. You need to know the DVR, or otherwise you will not be able to find the player...

Then if you have a microphone, what is your question?

With 3108-E you can record all 8 channels at CIF@25fps each channel; or you can record all 8 channels at D1@6fps each channel; or you can mix them (say, 4 ch D1@6fps and 4ch at CIF@25fps). With 3108-H you can record all 8 channels at 2CIF@25fps each channel; or you can record 2 chahnels at D1@25fps and 6ch at CIF@25fps. Keep in mind that I think this depends on firmware, I have used 3108-H that only allowed me to do "2 chahnels at D1@25fps and 6ch at CIF@25fps", and they did not allow "8 channels at 2CIF@25fps each channel".

You will have to hop from router, to router. From the outside router, you will need to forward the needed ports the the second router's IP address; from there, forward the ports to the third router IP address; and from that one, forward ther ports to the DVR IP.

That is the DVR with the lowest specs available from Dahua (their entry level model). So to answer your question, no, it's not one of the better ones. It is actually the worse one they currently manufacture. Note that I do not mean it is a bad unit, but it is the one they have with the lowest specifications and the least options. But it does do what you are asking for, and I am sure you should be able to find it much cheaper than $200. Last 31xx units I have gotten from Dahua were not 31xxE any more, they were 31xxH which have slightly better specs. So I do not even know if 31xxE are still being manufactured. http://www.dahuasecurity.com/products/dvr3104-3108-3116e--65.html http://www.dahuasecurity.com/products/dvr310431083116h-217.html

A mini Android device that connects to the HDMI port should do it. Something like this: http://es.aliexpress.com/item/MK808B-bluetooth-android-mini-pc-new-Stable-Dual-core-RK3066-mini-pc-dual-core-Android-HDMI/764597463.html Note that I have no idea if this one is good or bad, just found it on Google. I do have a couple of customers with devices like this one, connected to a TV working 24h/day, just showing cameras. Cheap, and way more energy eficient than a normal computer. Google for "android hdmi stick" or "android, hdmi dongle", or something like that. If your camera has Android client, you can just leave it running there forever. If it must be RTSP, you can use some RTSP client, like VLC for Android. I think that your Apple TV also should be able to do it, there is must be some way to avoid that it goes to sleep...

There are many routers that support 3G connection. I do not remember the model, but I have a TP-Link nano router where I can connect a 3G USB stick, and make a DVR, IP camera, etc. uses a 3G connection. I did a few tests, and it worked great. The nano router is powered with 5V, so I could even power it from a USB port on the DVR.

Looks like the same product, but this one does not include the power supply.

Ahhh, I did check out the PDF the first time... But I guess I just did not try hard enough The command http://ip/Streaming/channels will list all the available channels, and I see that there are 8 channels available: 101 102 201 202 301 302 401 402. Each channel (1 2 3 4) has two stream (01 02). So with the command http://ip/Streaming/channels/101 will show me the information on main stream on channel 1. And with the command http://ip/Streaming/channels/101/picture I will get a screenshot from channel 1, and I can also use channels 201, 301 and 401. It is strange that while my main streams are 704x576 and the substreams are 176x144, no matter if I make the screenshot on main or substream, both give me a 704x576 screenshot. But I can live with that. " title="Applause" />

That is a BNC connector. You need a video to VGA converter with BNC input.

Hi buellwinkle, Did you test this on and DVR or just IP cameras? I just tried it and it worked great on a DS-2CD7153-E and DS-2CD8153F-E, but I could not get it working on a DVR. I tried an old 7204HFI-ST and a brand new 7204HFI-SH with no luck. 7204HFI-ST gave me a 404 page not found, I guess the old firmwares just won't support this. 7204HFI-SH gave me a 403 forbidden error after asking for user/password, so it does seem to be supported, but maybe something needs to be changed on the URL or I need to change some permissions. http://ip/Streaming/channels http://ip/Streaming/channels/1 The first command works OK and shows me a list of all channels and their configuration, but the second one gives me an invalid operation. Any hints? <ResponseStatus version="1.0"> <requestURL>/Streaming/channels/1/</requestURL> <statusCode>4</statusCode> <statusString>Invalid Operation</statusString> </ResponseStatus> Thanks!

Dyndns is surely not in chinese... http://www.dyn.com

That is something I didn't knew, thanks for sharing all your Dahua knowledge dexterash! " title="Applause" /> So, let's say, with a Dahua NVR3216, is it possible to record 4ch at 1920x1080@25fps; but it would also be possible to record just 3ch at 1920x1080@25fps, and also at the same time 4ch D1@25fps from a Dahua 4ch DVR?

Does the DVR have more than one output? BNC, VGA, HDMI, etc. If so, try another output, some DVRs will only show menus on one of the outputs, maybe for some reason when you reset to defaults now the menu is showing on the output you are not currently using.

Do you have your DNS correctly setup on your DVR? With no DNS your DVR is unable to resolve names (like smtp.gmail.com). Check your settings on Additional function -> Preferred DNS. Here is a guide with the exact settings you can use with your DVR (which is manufactured by Dahua) and Gmail, it is in spanish but it should help you out. http://www.securamente.com/como-mandar-emails-por-smtp-desde-un-dvr-o-camara-ip-utilizando-gmail/

I actually gave it a try 2-3 days ago, and I thought it was quite... unfinished to say the least. I think Dahua is building a program from scratch to replace PSS, so they do have a lot of work to do, but I do not think the current version is usable.

That is awesome! " title="Applause" />

You are new, and are going to make a CCTV installation for a factory with cable lengths up to 1000 feet... You are surely going to learn the hard way, good luck.

Check to make sure that the ports in your router are still forwarded to your DVR.

I have to agree that there is no way you can be looking at the same time for the "best WDR camera", and "something inexpensive"...

Never used Swann, but that is not something hard to find on a DVR. I use mainly Hikvision and Dahua, and with both of them you can remove datestamp, timestamp and camera name.

Where are you located? I am sure this will differ from country to country, in some places it might be ok to do this, in some others it might not.

Yes, you can if your DVR supports PTZ domes.

Well, if it does not detect the hard drive, where do you expect it to record...? My suggestion on what to do, take out the hard drive, and try it on a computer. If the computer also does not detect it, you have a dead hard drive.
