Issues with DG-M1X HD 960P

[DavidVentura]

Hey I bought a DG-M1X HD 960P but am having issues getting a shell.
I just set up a dhcp server on my notebook to isolate this device from the internet while setting it up.
I get connection refused if I try to ssh or telnet to the camera; but I can watch the rtsp streams (even though they are quite low quality and onvif2 seems to lag >10sec)

Any ideas? If I curl to the camera at port 5000 I get some xml back..
How did you get the shell originally? Simply telnet?

Hey, Yes over telnet. I simply plugged it into a DHCP enabled switch and made the wifi settings over telnet. Is telnet running in your firmware (scan port 23)? DavidVentura <[email protected]> schrieb am Do., 20. Sep. 2018, 18:32:

I commented a bit hastily. I ordered 2 cameras and one of them works as described here - the other one doesn't seem to be running telnet.

But! The one that works said something via the speaker ("Setting up device" or something similar) while the other one doesn't say anything

[DavidVentura]

I opened the camera that did not offer telnet, connected via serial and started up telnetd.
I found a few differences between the cameras, I'll tag as working the one that came with telnetd.

Shows that the non working has lower framerate and bps.. (I can see this on the video quality, which prompted me to start investigating)

Also the non working will always rotate to the left when I send any command for it to rotate..

Increasing fps on the second camera
yields this on dmesg

[   26.890000] fps is 25, support max shutter time is 20480000 curr shutter_time 0
[   27.050000] mirror_patter 3
[   28.720000] win_height:0 win_width:0

and the stream is 15fps

but on the good camera I get

[   26.990000] fps is 25, support max shutter time is 20480000 curr shutter_time 0

@DavidVentura
How did you actually log into the camera that had no telnet then? Is there a way through serial port?
Asking because I have sort of bricked my camera by carelessly modifying /npc/boot.sh, and now it does not boot.

I can connect to the cam through serial, even got into the uboot shell - but now I have no way to actually modify the file though serial?

[DavidVentura]

if i remember correctly, i either got a root shell directly from the serial connection or it had a silly user/pwd (like admin/admin or root/root)
