yakky 0 Posted September 19, 2012 Not sure if this is old hat, but I finally stumbled upon the telnet password for most dahua ip cameras and DVRs. This was posted on Rory's board. root:vizxv Also, neat development: http://tanidvr.sourceforge.net/ I poked around the dvr, seems to be a lot of stuff based on LUA.

gadfly 0 Posted September 30, 2012 hmmmmm..... so if I settle on a Dahua looks like I need to look into stopping telnet in my router. Thanks Share this post Link to post Share on other sites
Liquid_Squelch 0 Posted October 6, 2012 wow, awesome info. Telnet works great on my DVR, just snooping around for now.... nothing interesting to find. But, that TaniDVR looks like something I could use. I was looking for a Linux program (or as they call it on the sourceforge page, "aproper OS". I'll be loading that up tonight Thanks for the info!

buellwinkle 0 Posted December 27, 2012 I tried to go in and change the main logo, can probably get more for the DVR or IP camera if it said Axis or Mobotix. OK, only kidding, I want to my name up there. I got my logo.jpg file in the /tmp directory, same pixels (256x55) but I can't find a way to copy it to the /mnt/web/image directory. It's read-only, not usually an obsticle for me but this one is SquashFS format that I'm not familiar with. I believe this is some sort of compressed read only file system. So my guess is I would have to un-squash it somehow, mount it as read/wite, copy my logo.jpg file and then squash it back. Anyone tried this yet? I know it's possible because Q-See puts their logo in there over the Dahua logo. Share this post Link to post Share on other sites
Liquid_Squelch 0 Posted December 27, 2012 What program are you using to FTP to the DVR? I tried ports 21, 22, 23 and was unable. When I telnet in, my images are located here: /usr/data/Data I have no images in /tmp Share this post Link to post Share on other sites
danito 0 Posted December 29, 2012 I don't have a Dahua DVR but I just got a Dahua Camera and started looking around a bit. From what I read here the camera and the DVR appears to be running the same software... On my camera there is no FTP server installed, so you need to telnet into your DVR and FTP out files that you wish to look at, using 'ftpput'. To do this you need a FTP server running somewhere where you can upload files. There is also some basic unix commands that are implemented in Busybox but to which Dahua didn't put symlinks, like df and top. To run them you need to issue 'busybox df' and 'busybox top'. Useful to find out how much space is left on the camera, or how much CPU is used. Buellwinkle, you seem to have it right with SquashFS, it looks like you'll have to dd the partition in a temp file, ftpput it somewhere, unsquash it, change the logo, re-squash it, ftpget the new file on the dvr/camera, and dd again the file to the partition. I don't have the camera running right now but with df it's easy to find the mount point. BTW you work in IT? On a side note, if anybody is interested, there is a way to get a snapshot of the camera in HTTP, it's not a MJPEG feed, only a still JPEG. But anyway it's not that bad, I was able to get about 3fps out of the snapshot URL with ZoneMinder. It's definately better to go with the RTSP feed but it's quick & dirty if you want to have an idea of what's going on at home while you're away. Here it is: http://:9988/onvif/media_service/snapshot I believe you can add ?channel= to the URL if you want to select which camera you want on the DVR, it doesn't do anything on my camera for obvious reasons Oh and it appears to require NO PASSWORD, so draw your own conclusions!!

Allodo 0 Posted June 11, 2016 Thanks to soksavda for the url Now I have connection via telnet to my VTO2000A IP Intercom. Are there other commands which I can send via URL? Exists an list with commands? Is it possible to connect with WinSCP for copying files and analyse them? Share this post Link to post Share on other sites
andyh747 0 Posted June 16, 2016 I would also like to know if there's a list of commands which can be sent via telnet to the DVR. I would like the ability to change the display output so you can show the different views output to the HDMI interface. This should be a straight forward command set. Any pointers appreciated.
