    How do I reset a dhi-nvr4104-p-4ks2?

    If it was mine, I'd check out J29, above the board part number. Serial TTL, not RS-232

    R0 / DS-2CD2x32 BrickfixV2 brick recovery and full upgrade tool - enhanced.

    What you've described in detail looks good - so there is not an obvious cause for the bootloop, unless the bad block in the backup cfg_sec is implicated.. The serial console hopefully would provide a clue. I don't think an original - but what may be a 'hacked to English' version from...

    DS-2CD3145F-IS firmware upgrade

    What are you trying to achieve with hikpack? Hikvision changed the firmware packing scheme in 5.5.x such that hikpack no longer handles it. Remember also that the 'language change' in hikpack is only for the firmware header - it does not change the firmware language itself. To change your CN...

    Public port forwarding on firewall?

    Does the firewall log the probes and access attempts against the port? Any interesting exploit attempts?

    Forum technical problems getting bad?

    Did you do some endurance estimations? I'd imagine drive writes per day will be quite significant whilst @Arjun is still around ...

    Friends dont let friends install wireless cameras

    Probably an AI bot, wouldn't mind so much if the post wasn't just stating the obvious. We'll see if it's a placeholder for future edits.

    GDID and Windows 11

    I'm on Linux Mint 22.3 with Kernel: Linux 6.8.0-136-generic just now, been on Mint for quite a few years. It's easy to use, stable, with a good set of tools available for those 'research tasks'. ** edit ** On the rare occasion I might need Windows - I just boot up a virtual instance with Oracle...

    Russische dienst hackte camera's

    Translation : " In the Netherlands, Russians have hacked "a small number" of private cameras along routes where military goods are transported. The intelligence services AIVD and MIVD have alerted the owners so that they could take action, Defence reports. These are cameras that can be accessed...

    Capture Schedule delayed and stops after few days

    Relative to real time, or camera time? Is the camera time properly synced using NTP?

    Rename cameras in Remote Config settings?

    I don't use iVMS4200 much - so this may be wrong, but - What are the camera names in the NVR web GUI? I'm wondering if that's the origin of 'Camera 01' etc and it's being inherited from there.

    NVR

    Maybe try this method : https://www.ipcamtalk.com/threads/hikvision-camera-admin-password-reset-tool.2837/page-61#post-926390

    RF Detector?

    That's perfect, a full stealth result. That's one possible cause for the NVR behaving oddly now eliminated - it's not accessible from the internet such that any vulnerabilities could have been exploited.

    Camera Password Corrupted - Power Surge Knocks off NVR

    The camera should have been automatically activated by the NVR after you reset the camera to defaults. Odd that it didn't, when the channel is set to Plug&Play. But you can still add the camera manually. If the admin password that you activated the camera with is the same as the one the NVR is...

    RF Detector?

    It might be interesting if you repeat the test with the NVR connected as it normally used to be.

    RF Detector?

    Well done! Yes, that's a perfect scan result, there are no listening ports found on the inbound scan. A full stealth result, as it should be. However - a question - did you have the NVR powered on and 'connected to the internet' as you normally used to for reviewing recordings? Not just...

    RF Detector?

    OK, but here is a simple non-technical thing that you can do that may provide potentially useful information. One of the many services that will do an inbound scan from the internet to see if there are any holes in your inbound firewall protection. This just needs you to 'connect the NVR to the...

    R0 / DS-2CD2x32 BrickfixV2 brick recovery and full upgrade tool - enhanced.

    Good to hear - thanks for sharing. Not using the R0-specific method that you have used, the G1 cameras have a different architecture. I've not had my hands on a Chinese G1-series camera, so I've not explored how the region is defined, sorry.

    Hikvision NVR email notifications overriding IP camera email.

    Are both cameras connected to NVR PoE ports - such that the email notifications must go via the NVR, or are the cameras on the LAN such that they have direct access to the internet? If the former, maybe as an experiment reconfigure the newer camera power and network to operate on the LAN and...

    HikVision DS-7732NI-M4 versus DS-9632NI-M8

    Storage capacity - 8 drive bays with RAID capability vs 4 drive bays. A larger number of UHD resolution cameras. Recognising and being able to make use of a wider set of advanced camera capabilities. Not that the spec gives detail on that.

    R0 / DS-2CD2x32 BrickfixV2 brick recovery and full upgrade tool - enhanced.

    Min-System mode should allow telnet access, so the fixup script can be activated. But it would normally use the 192.0.0.64 IP address, not the 192.168.254.2 address that your SADP list is showing. I'm not sure why that is. If you change the PC IP address to, say, 192.168.254.100 does a telnet...

    R0 / DS-2CD2x32 BrickfixV2 brick recovery and full upgrade tool - enhanced.

    Is the camera still connected to the NVR PoE port? And the PC on the LAN? If so, the camera isn't directly accessible. If the camera is still connected to the NVR, either connect the PC to an unused NVR PoE port, or connect the camera to the same LAN as the PC and power the camera with 12v...

    Looking for advice on multi-site solution

    Some questions aimed at helping get constructive responses : Is this for camera traffic only, or other traffic also, if so what type? Have you been given a hypothetical budget to work within? That would require the maximum bandwidth of any solution, and also provide multiple point of failure...

    Router replacement question

    If you were able to do that - and also to arrange that the scope (the pool) of DHCP IP addresses was set to match the old router - then you should not need to go round all wired devices on the LAN and reconfigure their network settings to match the different defaults of the new router. Reserved...

    Help Needed: Hikvision DS-7732NI-ST Boot Loop - Looking for Full NAND Flash Dump (Board: DS-80088 REV 1.2)

    If the existing bootloader is still functional, and includes the tftp recovery capability that allows valid firmware to be loaded, maybe try flashing the new chip with the contents of the existing chip and then loading the valid firmware using the tftp updater.

    Is my Dahua DVR being hacked?

    Just in case you are unaware - Unless you are using a managed switch for the NVR / PC / camera(s) that has the capability to nominate a port for the PC to sniff traffic from, the PC running Wireshark will only see traffic directly between the PC and the NVR, and not any traffic between the NVR...

    Can not setup rtsp stream

    I've never had a problem playing RTSP streams under Linux (Mint), but it may vary with the specific codec in use in the stream. I am always a bit suspicious about attached executables, but your file has been pronounced as safe by VirusTotal.
