I'd need a pan/tilt head supporting absolute positioning, but I can only found products costing hundreds of euros; I am not professional, so I can't afford such a price for an amateur project; even just one axis movement would be enough, in a first instance, for testing; I need a 1° positioning precision or better. But the most important thing is that I need to send commands over wifi, or bluetooth, or as as last chance over cable, but not by 433MHz/866MHz remote control. Any suggestion? Should I look only for PELCO-supporting devices, or do also PTZ devices support absolute positioning? My budget is 100$. Even a china-product on Aliexpress or Banggood would be fine... but I can't find it.

Stream coming from my DVR can only be viewed using Internet Explorer as it requires an ActiveX. I'd like to see the stream using Firefox or even a cellphone, so I need to "hack" it a bit. Some reverse engineering reveals that the stream should be RTP on port 54000, but I did several test with Firefox, Realplayer and VLC, but I can't see the stream. Please note that I currently don't know if I have to specify any file name after urk xxx.xxx.xxx.xxx:54000 to access the stream, so any suggestion also about this topic would be appreciated. The DVR is a china clone named DVR8204 in the shop where I bought it, but "TW2700 DVR" by examining its HTML code. Strange thing is that by looking at the .js file inside the DVR I figured out that rtp ports for 4 video channels should be 64000, 64004, 64008 and 64012, but actually a port sniffer reveals that stream is coming out from port 54000 after the DVR receives "something" from ActiveX on port 6610.

Don't know original manufacturer. And don't know URL for rstp stream, if any.

did you succeed with hacking the ipcam?

No ideas?

I have a similar problem, I'd like to see my DVR video stream on cellphone, or on browsers other than IE. But my DVR uses an ActiveX! I know videostream is on port 54000 (verified with multiple port/ip sniffer), but how to "hook up" to it with VLC, RealPlayer, Firefox or any other player?

I recently bought a standalone DVR named just "8204S": http://www.kingshopitalia.com/dvr-videoregistratore-4ch-lan-web-mjpeg-p-139.html?osCsid=lrabu46rpcbfsgkf6aqfggc875 I successfully configured both it and my modem/router, so I can see internal DVR web pages from remote, even by virtual DNS. Unfortunately, that's all I can see: I am not able to see any video stream. The weird thing is that I CAN see video stream by conneting to local IP 192.168.0.5, but I cannot if I connect... to my PC from my PC itself, using the public IP! The DVR uses an activeX named iFlyNPSX.CAB , which I am not able to find info about nowhere. It should also be possibile to connect to the DVR using QQEYE SW I received bundled with the DVR, but actually I can't. I also received an additional mobile SW, called MyEye, but it does not install at all, and I can't find any info about it. So, te question is: do DVR use a standard method to stream video? Do they exist free SW to connect to generic DVRs? (both for Symbian phones and/or Windows PCs) If it can be of some use, I am able to see video steam coming from my PC if I use WebcamXP SW, so it shouldn't be an issue related to my ADSL.

My 8204S DVR has network connection, USB support and it mounts Linux: does anybody know if/how it is possibile to access DVR filesystem from PC, rather than by using Internet Explorer activex to download recorded file from the DVR?

The DVR has no local playback? yes, I can play all stored clips through Internet Explorer, but I can't delete/copy/rename them. Just play.

Emulator is not the correct word here. This DVR appears to be a Chinese made Linux (embedded) DVR. Your only option would be to take the drive out and plug it into a computer and see if you can mount the drive. Being that it is Linux the drive is probably formatted ext2/3/4 or some type of journalized filesystem which will not be playable in Windows. You could try grabbing a Linux boot CD (Ubuntu install cds for example) and seeing if you can mount the drive. Even if you do mount the drive, the recordings are probably not stored in a standard video container. I know all of these, that's why I asked for a method to use the DVR itself to access the recordings.

Problem solved: the router wizard mis-configured my provider (Libero), by pre-setting PPPoA connection rather than PPPoE, and PPPoA does not allow autoconnection. http://win98.altervista.org/DVR-8204/auto-connect-libero.JPG

I connected my web-DVR to my router. I can properly access internet from PC, and DVR is properly configured to be accessed from internet. What I can't do yet is to get the router connected to internet when the PC is turned off: is it possible? Usually I gain access to internet from PC by accessing router page and clicking on CONNECT button..

PPPoA (I think "over ATM"). I tried... but I can't see the router from outside. I'll do further tests.

you must be more specific about the problems you encounter to allow us to help you. WHat does it happen upon trying to connect to the IP corresponding to DVR (both local and public)? Which error messages? You should be always able to connect to the DVR from your local network using an IP like 192.168.xxx.xxx, just read on your DVR (by using TV connection rather than web access) to see which local address it has been assigned, probably it changed since last time you tried. Once you can connect locally, you can restart configuring properly it.

Which sensors can I plug into this DVR? http://www.cn-dvr.com/manual/8204english.pdf Or, better, which are technical specifications of such sensors? Which V/I does the unit expect to see on its ports to get triggered?

I did additional tests: alarm is triggered if input is set to HIGH and connected to nothing; connecting it to GND stops the alarm.

I guess it depends on me, not on the providwer... How is it supposed to work? Assuming I have all devices off (PC, DVR and router), should it be enough to turn on DVR and router to get them connected to internet?

I thought this too, but any option I set ("high" or "low") for the inputs, connecting them to GND does not have any effect. That's why I'm asking if I have to apply some voltage.

Using a different PC in same local network, I eventually obtained some results... although weird: Working settings: Uploaded with ImageShack.us Uploaded with ImageShack.us Weird things: *IE 8 used in both PCs, even same built. *Same settings on both IE. *Same router, no settings changed. *Same OS (Win XP SP3). Weirdest: look at second picture: *why is IE downloading from local 192.168.0.5 although I clicked DOWNLOAD button on remote page on 151.xxx.xxx.xxx ?!? *why Port Explorer shows port 20000 is used on this PC rather than on remote like for streaming and playback?!? Others: * why is the activeX using port 54000 for any channel, although script specifies 64000 + 4*ChannelNumber? * what the hell is port 6610 for?!? * why manual of a DIFFERENT unit recommends to open ports 54000-54030, 6610 and 3180?!? Have fun with finding the answers!

no manufacturer label on the unit, just a serial number Google can't find... I deleted the activex (doesn't it exist a better method to uninstall plugin from IE8 than roughly deleting files from windows\system32 ???) and reinstalled it, nothing changed. Could IE8 by the cause of the trouble? I just tried the "download" option of the DVR, but IE8 prevents script from opening the window to select folder to save file to! same script works in office PC, which has IE7 installed (but which can't access DVR from remote... ). Anyway, inserting download path by hand, download starts, file is created... but it never grows, progress gauge does not increase, nothing happens. "Fun" to see that download script use an even additional 64030 port... Even more funny to see is that in the DVR CD there IS a Viewer SW (I didn't find it before because it's in DOC folder ), but it can just view already downloaded MJPG files!

Never mind, it's not it (although it IS also available on same online store: http://www.kingshopitalia.com/dvr-videoregistratore-4ch-mjpeg-500gb-p-142.html) What about this "Vtek" site?!? http://www.vtek.com.br/ How do I browse it???

after long searches, I came to this weird page comlpaining about DVR cloning! http://www.cn-dvr.net/enindex.html Although my DVR has no built-in monitor, I suspect this is the original manufacturer, as looking around for patent n. 200830253597.6 I found this manual: www.cn-dvr.com/manual/J104English.pdf If that's true, the manufacturer would be "ShenZhen Skybest Electronic Co.,Ltd.". First picture is very similar (but not the same) to my device. But the device in that manual completely lacks external alarm inputs, so I don't know what to think... I'll check for labels on the unit. I thought "MJPEG" was a streaming standard... Do you know where to download from the CMS plugin, besides... from my DVR? I'll try deleting it and reinstalling from scratch. But... how do I uninstall an IE activex/plugin?!?

Just guessing: I "downloaded" from the DVR a .js file containing scripts associatd with the video straming page, nad the sources "talks" about port 64000 + 4 * Channel , and activating debugging in Internet Explorer shows Channel allowed values are from 0 to 3. I wonder how I can exactly determine the actual manufacturer of my device and how to find a complete manual.

I didn't yet understand if this is actually an AvTech, anyway I know it mounts embedded linux. What do you mean by "changing all the ports"? BTW router is Sitecom WL-613, not "54G".
