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.

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?

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.

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

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.

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 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..
