    reset password help

    It looks like the device has a serial console UART available - the 3 holes near the center of your image, marked G (ground) T(transmit) and R (receive). If you hook up a serial TTL to USB convertor (suggest a PL2303-TA based one) you might be lucky and find a command to clear the configuration...

    Multiple cameras showing in one channel

    If this is a Hikvision NVR, the PoE ports will only connect to one camera at a time. If the PoE switch is connected to an NVR PoE port only one camera at a time will connect. The PoE switch needs to connect to the same network as the NVR LAN interface, not an NVR PoE port.

    Cams / NVR Arrived - Have I Made a Mistake :-/

    Not on the hub web GUI, unless they've added that capability on the Hub 5 after user feedback. It's possible on a rather cryptic URL hack, but as you say, best left alone.

    Only 4 days of playback!

    Maybe I've misunderstood what you're advising but I don't understand why you'd want to install 4k cameras and only record the substream when all that's needed is to size the HDDs to match the needed history. The whole purpose of the installation is to be able to see enough detail to recognise or...

    What IoT camera could I buy with vulnerabilities to test?

    One of the earlier methods to find vulnerabilities was to unpack and disassemble a device's firmware, analyse the operation, and manually look for weaknesses in how it's been constructed. That's much more difficult now though, as the firmware of the major suppliers has been progressively...

    Bricked new tandem speed dome camera

    The Hikvision tftp updater doesn't support filesizes over 32MB. To get round that, the Scott Lamb Python2 clone doesn't have that limitation. https://github.com/scottlamb/hikvision-tftpd

    2MP 1/2.8" sensor camera

    By enabling the 'Virtual Host' tickbox in the NVR web GUI Network Management | Advanced Settings | Other tab, like this : Then use the new column of links at the far right side of the System | Camera management page, called Connect or Join depending on firmware version. The links provide...

    Interesting! I'm curious how you managed to retrieve that.

    Camera's not showing up at all

    I just checked a HiWatch NVR-208-M/8P with firmware 3.4.95 that I'd forgotten I had. In the VGA/HDMI interface, under 'Camera / Camera management' there is a tickbox 'Show password of IP camera' which after being given the NVR admin password adds a new column between Status and IP address that...

    Camera's not showing up at all

    By doing this, you have effectively 'orphaned' the cameras as the NVR is no longer configured with the camera passwords. The original passwords for the cameras would have been either the same as the NVR password, or be the camera-specific password that the later NVR firmware has the facility to...

    Jennov 8mp POE PTZ

    That's going to depend on which ONVIF events the camera generates. They will generally be quite limited, maybe just motion detection. You can see generated events if you connect to the camera with ONVIF Device Manager, the Events page will list what's being generated. Plenty of Chinese IP...

    Hikvision DS-7616NI-E2/16p NVR and DS-2CD2143G2-iu camera compatible?

    Hikvision DS-7616NI-E2/16p NVR and DS-2CD2143G2-iu camera compatible?

    By that do you mean that you reset the camera to 'Inactive' - can be done through the camera web GUI that you have access to - and then connected it to an NVR PoE port that's operating in Plug&Play mode? Alternatively, change the camera IP address to be the same as that expected by an NVR PoE...

    Hikvision DS-7608NI NVR-ISP 0.0.0.0.

    Do you have the PC connected to an NVR PoE port? How is is seeing the PoE-connected cameras?

    Dahua NVR I think bricked? Powercut

    Does the NVR definitely have a serial (RS-232) port? Usually that's just on the bigger models, a DB9 connector on the back panel. Most (and I'm unfamiliar with your particular model) have serial TTL interfaces via an onboard connector, which needs a different type of adaptor.

    Hikvision DS-7608NI-I2/8P bricked after updating to the latest version

    Beware of suggesting this to any users - instances of bricking, both NVRs and IP cameras, can occur via any method of updating if the jump in firmware version crosses a boundary where the structure holding the configuration has been updated, and the newer firmware doesn't have support for an...

    Need a perfect solution for Hikvision NVR windows application.

    Depending on how well connected your (very risky) port-forwarding remote access works - have you tried iVMS-4200 A heavyweight but very functional application.

    Can't access Dahua LPR camera via its IP address anymore

    Maybe a duplicate IP address on the LAN? So it works OK when the LAN is not connected. With the PC on the LAN, and the camera disconnected, does a ping to the camera IP address give a response?

    The bootloader is well past in your console screenshot. Hint - in PuTTY you can copy / paste all of the screen rollback text into something like Notepad etc to edit and post much easier for you and the readers. Use the 'Copy all to clipboard' option in the menu button at the top left of the...

    Bricked DS-2CD2342WD-I TFTP Firmware loads ok but still bricked

    That's a standard comment when UBIFS is used for the file system - not quite sure what it means, maybe all available are allocated for use. Here is a sample serial console from a somewhat similar model - DS-2CD2142FWD-I showing the use of the 'card' and also the LEBs comment. Hit Ctrl+u to...

    Bricked DS-2CD2342WD-I TFTP Firmware loads ok but still bricked

    This I believe is the cause of the reboot - the device hardware descriptor block cannot be read. This holds the device-specific data such as region, serial number, model variant, capabilities etc. So that's a fatal error when that data is missing. I'm trying to remember, but I'm not sure, if...

    Camera stops transmitting during the day

    With the repeatable problem, is there the possibility to temporarily connect using an ethernet cable to see if that changes the problem? Even a good WiFi signal can be impacted by too much competing and colliding traffic using the same channels. Presumably there are people (therefore devices)...

    Hikvision DS-7216HQHI-K2 password won't reset

    Is the PC IP address in the same range as that of the DVR? SADP normally does not need this for discovery - might need it for password reset, I'm not sure.

    HIKVision 7608 installation driving me nuts

    If the cameras are from Hikvision or one of their OEMs, SADP will find them if you plug the PC into an unused NVR PoE port. When the PC is on the LAN, only the NVR will be found, the PoE ports are not accessible from there, as you have discovered.

    Bricked DS-2CD2342WD-I TFTP Firmware loads ok but still bricked

    Agreed. You are observing network traffic, and the tftp updater is working OK. The network is fine. There is another reason the camera isn't fully booting, and the serial console output will likely show why.
