• Swann CCTV won't communicate

    From Davey@2:250/1 to All on Saturday, December 09, 2023 14:51:47
    I have a two or three year old Swann CCTV system, that lay in its box
    for over a year before I started to use it. All seemed well.
    There was a period where it was regularly shutdown by powering it off,
    which I know is not good. But it still comes back up when re-booted, to
    exactly the same display as when it was last shut down, which can now
    only be done by powering off.
    The problem is, that I cannot get into the Setup menu, which also
    allows an orderly shutdown. In theory, you move the cursor to the bottom
    left of the screen, a few icons pop up, and you click on the left-most
    icon, which brings up the box for entering ID and PW, etc. But it
    might take 5 or 6 attempts to get the box to be displayed, and when it
    is displayed, the first attempt to enter any character instantly shuts
    the box down, and I'm back to square 1.
    I have tried plugging in a keyboard and interrupting the boot, but I
    have not found the magic combination of keystroke(s) that will interrupt
    the boot process.
    I have tried Swann Technical support, which is useless even when I can
    finally get to discuss this with a human being, which is harder than
    extracting blood out of the proverbial stone. It drives you round in
    circles, never remembering anything of what was discussed two minutes
    ago. Not a good advert. for AI, more the opposite.
    Finally, Swann's chat-bot. responded today with the comment: "Your
    device is now too old, technical support is no longer available". I
    won't be buying any more of it from them, then.
    All I want to do is to, first, be able to interrupt the boot procedure,
    and second, go from there to at least see what I can see. I don't even
    know if it uses Windows or Linux, but the 'app' that is supposed to let
    you interrogate it to find its MAC address is Windows only. I already
    know the MAC address, and the rest of the procedure that the 'app' is
    supposed to enable again assumes that you have access to the menu,
    which I don't.

    Any help gratefully received.

    In the absence of any response to my post, I can at least add the
    information that it responds to a Cntrl/Alt/Del keyboard sequence,
    implying that it might use a Windows OS rather than Linux. All it does
    is Restart, though, so it is not of much help.

    Again, any help much appreciated.

    Port scan with nmap it can sometimes tell you what the OS is.

    Also as windows costs money and Linux does not its more likely to be
    busybox but that's only a guess

    Thanks.

    nmap {Swann} gives me:
    PORT STATE SERVICE
    85/tcp open mit-ml-dev
    554/tcp open rtsp
    9000/tcp open cslistener

    which means nothing to me! I find:
    a reference to ClearOS for the mit-ml-dev.
    rtsp seems to be part of the streaming process.
    cslistener sounds like a similar process.

    Any more help again welcome. But this is a good start, thanks.
    As you might gather, I am in, for me, uncharted waters here.

    I have tried again several times to interrupt the boot, to no avail.
    And again, every attempt to engage the Menu box just shuts the box.

    1) As others have suggested, this is almost certainly a bespoke Linux

    that the chances of it being anything else are pretty small.

    3) You make no mention of having a manual for it, do you have one? If
    not have you tried to find one online?

    4) Failing 3, or additionally to it, have you tried looking for a
    useful YouTube video, or hardware specific social media group? You may
    find that people at uk.tech.digital-tv may be able to help, as some of
    them install pro CCTV systems, so I've added that ng to this reply.

    5) Have you tried a factory defaults reset?

    6) Can you log into it using a serial or ethernet connection using such
    as putty and protocols such as telnet or ssh?

    7) The curse of these small systems is often the PSU, and errant
    behaviour such as you describe can be a symptom that it failing. Is it
    yer bog-standard common-or-garden wall-wart, or POE? If the former, do
    you have a similarly specced one for something else that you could try?
    Or, if you have the kit, or know someone who has that you could borrow
    to test it, does using POE improve matters?

    8) Another example of capacitor rot? If you can open up the PSU, check
    the caps for signs of bulging, etc, and if any are found, replace them.

    I have tried again several times to interrupt the boot, to no avail.
    And again, every attempt to engage the Menu box just shuts the box.

    9) As you suggest, you can often interrupt the boot - common
    keystrokes are: any, <Return>, <Esc> - but this usually involves some
    sort of direct serial connection using a suitable interface such as a
    TUMPA suitably connected to known points on the PCB, and the connections
    may require soldering. The information required to be able to do this
    might be found in a YouTube video, hardware specific social media group,
    or similar.

    Can you take the lid off and look inside? Take some pictures and post a
    link?

    Does it have a HDD? If it's Windows you might be able to pull the HDD and mount it on another machine. Likewise if Linux.

    Looking at the hardware might give you some clues. eg if there's a big chip with a heatsink on it, it could be an x86 PC. If it's a bunch of smaller
    chips like a Raspberry Pi, then it might be an embedded Arm Linux thing.

    Does it work without the HDD? If it's an Arm thing with the OS in flash, it might not need it to boot.

    If Linux, there is often a serial console available on a header somewhere. What access it gives you depends on how locked down the unit is.

    Without a model number it's very hard to make any further progress beyond speculation.

    See note earlier, but briefly, the online manual is no help for getting

    running.

    Yes, They all assume that I can access the menu, which I can't. Maybe
    the other ng may come up with an answer.

    5) Have you tried a factory defaults reset?
    That requires access to the the menu, which I don't have.


    6) Can you log into it using a serial or ethernet connection using
    such as putty and protocols such as telnet or ssh?

    See earlier response re: ssh and telnet. Briefly, "No entry allowed". I thought, maybe erroneously, that putty was for Windows, as well as
    windows.


    7) The curse of these small systems is often the PSU, and errant
    behaviour such as you describe can be a symptom that it failing. Is
    it yer bog-standard common-or-garden wall-wart, or POE? If the
    former, do you have a similarly specced one for something else that
    you could try? Or, if you have the kit, or know someone who has that
    you could borrow to test it, does using POE improve matters?

    The PSU is use-wise pretty new. This strange behaviour is predictable,
    the only thing that is not exactly the same is the number of mouse
    button presses required to bring up the menu, it may be one, it may be
    five, or anything in between. But every single time that I manage to do
    that, the first character entered into the menu box dismisses the menu.

    8) Another example of capacitor rot? If you can open up the PSU,
    check the caps for signs of bulging, etc, and if any are found,
    replace them.

    It is a wall-wart. I don't think it's the PSU, it is something in the
    software. But I am prepared to admit it if I am proved wrong.

    I have tried again several times to interrupt the boot, to no avail.
    And again, every attempt to engage the Menu box just shuts the
    box.

    9) As you suggest, you can often interrupt the boot - common
    keystrokes are: any, <Return>, <Esc> - but this usually involves
    some sort of direct serial connection using a suitable interface such
    as a TUMPA suitably connected to known points on the PCB, and the
    connections may require soldering. The information required to be
    able to do this might be found in a YouTube video, hardware specific
    social media group, or similar.

    I had never heard of a TUMPA until now, and am unlikely to go to those
    lengths, even if I could find the information.
    Finally, I was discussing this with a colleague today. I have decided to continue to try to fix it, but non-destructively, ie no prising open of wall-wart PSUs. It is currently doing the basic job it was purchased
    for, to allow me to monitor the patio at the rear of the house, but I
    cannot record anything, so it is live vision only. But it is mainly to
    observe visiting wildlife or neighbouring cats. I will look at buying a
    better system at some stage for general around-the-house monitoring and recording, when my current system (Dell from 2000, and Zoneminder!)
    finally expires. In the absence of any knowledge that gets me into the
    Swann software/OS, I will keep trying to interrupt the boot.
    Interrupting by keyboard has always worked for me on desktops and
    laptops, it should work on this thing.

    Hmm, I didn't manage to find much on that. There's some internal pics of
    the DVR8-5580: https://gadgetblogist.wordpress.com/2019/05/10/swann-dvr8-5580-noisy-fan-fix/

    What's interesting there is the text RS-DM-372B. Apparently the DM stands
    for 'Dedicated Micros' who are the board designer/manufacturer.

    Supposedly there are default passwords for those: https://superuser.com/questions/739794/how-do-i-reset-the-password-on-a-dedicated-micros-dvr

    but yours isn't listening for telnet (port 23) so perhaps not much help. (although you could try telnetting into the ports you do have and see if it replies)

    There are also some tricks that imply you can reset it by pulling the hard drive and deleting files (copy somewhere safe first): https://www.cctvforum.com/topic/8588-dedicated-micros-lost-password/

    Even if not, it sounds like that forum is a good place to ask for further help.

    I suppose you DID run nmap from another box on your LAN since its designed

    Knowing nothing about video streaming applications, that's about as much

    suggest:

    - contacting the source of your gadget and asking for a manual if you
    don't have one

    - pointing Wireshark, if you have it installed, to see what. if anything
    is sent and/or received by your streaming gadget when it's starting up.

    - are there any relevant log file entries that you can access on your
    streaming device?

    - since I see you're using a Fritz-box, you might want to look at its
    manual (available by download) to see if it can offer any diagnostic
    help.

    When trouble shooting a relatively unfamiliar device or application, I
    tend to look at logs with less, gedit or vi, since both have good search abilities, and then fire up Wireshark if I suspect it might be a comms problem. .

    My laptop. My CCTV box, the Dell. Also, two Humax DVRs, which I think
    use Linux of some variety.

    much as I can suggest. If the above doesn't give your pointers I can
    only suggest:

    - contacting the source of your gadget and asking for a manual if you

    I always get pointed to the same one, which icnludes a load of
    different models, and is of no use at all.

    - pointing Wireshark, if you have it installed, to see what. if
    anything is sent and/or received by your streaming gadget when it's
    starting up.

    I have never managed to get Wireshark to give me anything I understand,
    which I am sure is my problem, but does not help. What it describes, I
    don't see when I fire it up.

    - are there any relevant log file entries that you can access on your
    streaming device?

    - since I see you're using a Fritz-box, you might want to look at its

    I might try that, thanks.

    So what, if any, ports are open? nmap should show you that.

    I suppose you DID run nmap from another box on your LAN since its

    Is there any system you know of on your LAN that's running Ubuntu?

    Knowing nothing about video streaming applications, that's about as
    much as I can suggest. If the above doesn't give your pointers I
    can only suggest:

    - contacting the source of your gadget and asking for a manual if
    you don't have one

    - pointing Wireshark, if you have it installed, to see what. if
    anything is sent and/or received by your streaming gadget when it's
    starting up.

    - are there any relevant log file entries that you can access on
    your streaming device?

    - since I see you're using a Fritz-box, you might want to look at
    its manual (available by download) to see if it can offer any
    diagnostic help.

    When trouble shooting a relatively unfamiliar device or
    application, I tend to look at logs with less, gedit or vi, since
    both have good search abilities, and then fire up Wireshark if I
    suspect it might be a comms problem. .


    I got Wireshark working, simply a matter of using the command 'sudo
    wireshark' instead of using the icon. Easy when you know, not when
    you don't.
    I performed a re-boot on the Swann. and the only packet recorded
    was a simple enquiry:

    "SwannCom_ae:36:11/Broadcast/ARP/68/Who has 192.168.1.254? Tell
    192.1681.195"

    192.168.1.254 is the Fritz!Box, ~~195 is the Swann.
    That's all from the CCTV box.

    There is a shit-load of stuff going on! But very little Swann.


    For what it is worth, I've been involved in CCTV stuff for a long
    time, and if I can be honest with you, Swann is a complete POS that
    was heavily sold by Maplin before their eventual demise.

    The eaiest thing to is to bin the Swann and start again with a decent
    qaulity DVR like Samsung, Distributed Micros, Hikvision or Dahua.

    What I do is I set up a wireguard VPN server at home (easily done on a Rasberry Pi.)

    Then install the wireguard app on the iphones, ipads and android devices.

    You then do a portforwarding rule in the router to forward to a port on
    the wireguard server.

    DO NOT FORWARD any ports to the DVR.

    Then install the CCTV viewer app on the mobile devices.

    Connect over VPN and then access the DVR.

    however, you will need to get a static IP address for your homebroadband unless you set up NOIP or DynDNS.

    P.S. if you're still using CVBS cams rather than A-HD or CVI or TVI,
    there are some Samsung SRD 860 DC on ebay from time to time.....

    Be aware that that interpretion of ports is just from a standard list (/etc/services) and doesn't necessarily correspond to how the ports are used
    by a particular device. While RTSP makes sense, I think the other
    descriptions are red herrings. From various googling, it appears port 85 is the webserver for the DVR and port 9000 is the 'control' port, for what purposes unspecified.

    I'm guessing Davey has already tried the web interface on http://dvr:85/
    ?

    Also to note, while I spotted a potential link with Dedicated Micros
    upthread, it's possible this is a red herring too: while it seems DM went
    bust in 2016 and were reincarnated it seems their hardware is a bit more enterprise-y (hundreds of cameras, etc) than this unit, which looks to be
    more of a small business kind of thing.

    Taking the lid off and taking some clear photos of the board would help for
    any clues to identify the real manufacturer, since it seems Swann just
    rebrand others' hardware. Even if we don't know, the CCTV forum might.

    I have a two or three year old Swann CCTV system, that lay in its box
    for over a year before I started to use it. All seemed well.
    There was a period where it was regularly shutdown by powering it off,
    which I know is not good. But it still comes back up when re-booted,
    to exactly the same display as when it was last shut down, which can
    now only be done by powering off.
    The problem is, that I cannot get into the Setup menu, which also
    allows an orderly shutdown. In theory, you move the cursor to the
    bottom left of the screen, a few icons pop up, and you click on the
    left-most icon, which brings up the box for entering ID and PW, etc.
    But it might take 5 or 6 attempts to get the box to be displayed, and
    when it is displayed, the first attempt to enter any character
    instantly shuts the box down, and I'm back to square 1.
    I have tried plugging in a keyboard and interrupting the boot, but I
    have not found the magic combination of keystroke(s) that will
    interrupt the boot process.
    I have tried Swann Technical support, which is useless even when I can finally get to discuss this with a human being, which is harder than extracting blood out of the proverbial stone. It drives you round in
    circles, never remembering anything of what was discussed two minutes
    ago. Not a good advert. for AI, more the opposite.
    Finally, Swann's chat-bot. responded today with the comment: "Your
    device is now too old, technical support is no longer available". I
    won't be buying any more of it from them, then.
    All I want to do is to, first, be able to interrupt the boot
    procedure, and second, go from there to at least see what I can see.
    I don't even know if it uses Windows or Linux, but the 'app' that is
    supposed to let you interrogate it to find its MAC address is Windows
    only. I already know the MAC address, and the rest of the procedure
    that the 'app' is supposed to enable again assumes that you have
    access to the menu, which I don't.


    It was the Trackball that did it.
    Some time after installing the system, I had mounted the DVR high up
    on a shelf, the only available space, and out of the way. This,
    however, meant that the mouse cord was at more than a stretch, so I
    bought a Logitech Wireless Trackball, enabling me to control the system
    from anywhere convenient. And it worked for everything that I used it
    for at the time, which was selecting camera display layout, or
    selecting one camera, and even zooming in on any part of the image,
    which was not described in the manual. Because it did what I asked of
    it, I had no reason to suspect it when later I could not do other
    things. Reverting to the original mouse has restored the missing
    functions.
    A good Christmas present, and information for any other users who might
    have similar problems.
