ZOSI ZR08MN (DVR) cannot talk to zoneminder

ZOSI ZR08MN
just bought this dvr from amazon, was attempting to add cameras to Zoneminder 135.12, no luck.
here is what zenmap intense scan says about the dvr:

according to Zosi DVR in Network settings:

HTTP Port 86

Mobile Port 5001

IP Address 192.168.000.025

Test button (when clicked says OK)

Yes, I can ping 192.168.0.25

The question then is, has anyone else tried this dvr yet?
I will continue to test it, will let you know of any conclusions.

See: https://wiki.zoneminder.com/Finding_Camera_Stream_Paths

Does it have Onvif? Does the User manual detail an RTSP path?

[halbatron21]

no, and no respectively.
The Manual is less than adequate.
I am now starting to suspect that this dvr, was only designed for cloud deployment.
I have tried many of the rtsp:// strings, too many to list, but have tried several.

You say :-

Code: Select all

HTTP Port 86
Server Port 5000
Mobile Port 5001

NMAP says :-

Code: Select all

23: A Telnet Port

If NMAP can't find a server listening on port 86 then there's no server there, nor anything listening at 5000/5001.

86 is a non-standard port for http, port 80 is assumed if you just http://the-device/ you'd at least need to visit http://the-device:86 to get there when it *is* listening.

So, it would appear that something is disabled/turned off. You may have to telnet in and do something on a command line to change this, and possibly save that as the default state so it sticks when you reboot!

What happens if you telnet in? Start working out what user name/password you may need!

[halbatron21]

found an issue, config.xml is not configured correctly.
settings at issue:

Code: Select all

<config>
<serverip></serverip>
<serverip></serverip>
<serverport>554</serverport>
<loop_nums>1</loop_nums>
<multicast>0</multicast>
<metadata>1</metadata>
<rtsp_over_http>1</rtsp_over_http>
<http_port>80</http_port>

according to that file, port 554 and 80 should be open.
I then did a factory reset, nothing changed. I only transcribed the relevent bits of the config.xml file, since putty isn't allowing me to cut and paste.
P.S. this file didn't change after i set the port to 86 in the settings dialog. The assumption is this file is blocked or disabled.
also apt is disabled as well.

I can confirm updating firmware will kill telnet access, after the update no ports are available. I found a file called pm_callback.sh, while I still had telnet access. I am betting this file sets up the connection to whatever displays the feeds. I think someone figured it out which is why they rolled out a firmware update from 3515 to 3520, which killed the open telnet port. I might be displaying some paranoia again though, wouldn't want to appear negative. I will close this off and wait for someone to roll out a independent firmware fix. I know, there I go again living in LA LA Land.

Gotta say, this DVR is not well designed. I was using the usb port, with a thumb drive to back up video and jpgs. Now, it will not see the usb drive, thought it might be the thumb drive, and tried another it wouldn't see that one either. I tried both thumbs on another machine and they worked fine. I will try flashing it again, but even if it works in my opinion the ZOSI ZR08MN is of poor design.

Addendum:
ROFL; I can flash it from the usb port, but it still won't see it after reset. The Process to flash this DVR, is to remove mouse, disconnect power, insert usb drive with latest firmware package from zosi support site, and leave mouse disconnected and power up unit, it will then display upgrading on screen, until zosi logo displays, followed by the zosi info dialog. You then power it off, remove the usb drive reconnect mouse and power it up click finish on info screen and you are done, for completeness, I do a factory reset as well. The other funny thing is when you plug in the usb drive the mouse quits regardless of port used.

The result is that you cannot pull the videos and or jpg's from the DVR without their cloud service and apps, which requires you to register with them.
I refuse to do that on principle.

While I'm sorry to hear of your struggle with this device, I think your conclusion is perfectly sound -- and one I 100% agree with.

Things that "can be backed up to the cloud" are fine, things that "must be operated in the cloud, through our service, and with working broadband/wifi/mobile signal at all times" are spyware/garbage dressed up as a revolutionary new idea. Emperor's clothes and all that.

As soon as your broadband/ISP/region of internet fails, or they remove the service just-because, or decide to charge you for the "free cloud" service (at ever increasing rates), you are dead in the water.

Thank You. I am not that upset about it, I can use it in the overwatch role if you get my meaning. The fact that we have revealed the drawbacks may prevent someone else, from making the same mistake. I thought I had purchased it from amazon, but actually it was an ebay purchase. I may try to open the firmware package and try rolling my own. I have not done coding in a long time, but might be able to wrangle something.
