    Critical vulnerabilities found in 'millions of Aruba and Avaya switches'

    At least with a managed switch, the flaw can be fixed. As it has been.

    HIKVISION DS-2CD2386G2 / DS-2CD2387G2

    Hikvision DS-7616NI-E2/16P upgrade

    Your screenshot shows that this is actually a Chinese NVR, with very old firmware. The barcode label with the -NI suffix is a fake. The usual consequence of attempting a firmware upgrade with EN firmware on a CN NVR is a 15-beep bootloop. But a CN E-series NVR can be converted to EN and fully...

    TruVision NVR TVN 11 only records video for third party cameras ONVIF Profile S

    It's likely that the NVR will simply record what's being offered to it by the camera. Do the (unspecified) cameras have a video type selection dropdown or tickbox to include audio in their configuration screen such as exists in Hikvision cameras, example below : When a camera is connected to...

    BI vs NVR

    Here is another live sample, now that darkness has come. There are no PTZs on that switch, all turrets. Note: Max power used by PSE: Class 0: 15.4W, Class 1: 4.0W, Class 2: 7.0W, Class 3: 15.4W Port State Priority Power Limit Power(W) Voltage(V)...

    BI vs NVR

    Just in case this determines anyone's buying choices ... Sorry, but I disagree. Based on actual experience, and also device specs. Even Pro series models (ie more RAM and faster processors) with active strong IR or white LEDs use no more than 5 or 6w worst case. I believe your figures are out...

    Amcrest NV4116E-A2 keeps losing Reolink Duo 2 stream

    It sounds like the (presumably fairly new) firmware on that camera is a bit bugged. Reolink doesn't have the best reputation for their firmware, as you'll have seen in multiple threads here. If you haven't already done so - it would be worth checking with the seller what the newest version of...

    Bricked iDS-7204HQHI-K1/2S(C) no HD or LAN

    That does make sense - that's what others have also used when the bootloader 'update' command is missing.

    Newer Hikvision offerings still using active/x controls?

    What firmware version are they currently running? Live View works OK plugin-free under Firefox in Linux, and Edge in Win10, on this version of firmware, and presumably the couple of later versions : A selection of firmware from here ...

    Bricked iDS-7204HQHI-K1/2S(C) no HD or LAN

    So (now no longer using just the phone so I can now see your PuTTY logs) I'm curious what command (if any) you used to recover the DVR. In your transcript I see no update command. So was it the built-in 'probe for a tftp updater' that re-flashed the firmware? I'd have expected that to rely on...

    Bricked iDS-7204HQHI-K1/2S(C) no HD or LAN

    Excellent! Well done. Re-flashing the firmware this way will reset the device to it's default configuration, so you'll need to set it up again. Unless you have a previously exported file you can import.

    Bricked iDS-7204HQHI-K1/2S(C) no HD or LAN

    With the caveat that I've not seen that DVR before - Interrupt the bootloader with Control-U Then at the command prompt, use printenv and help to see the variables and available commands. You may have to use setenv ';printenv' and setenv ';help' to get round the silly attempt to hide the...

    Hikvision RCE Vulnerability

    Provided you have the 'inform surveillance system' or similar enabled in the camera event linkage settings, you can use iVMS4200 to show you just the events on the continuous recording timeline. That's so much quicker than ploughing through a full timeline.

    Boot Loop after Firmware DH_NVR5XXX-4KS2_MultiLang_V4.002.0000000.5.R.220729

    Be a bit cautious - This may not be RS232, it's most likely serial TTL if the connector is on the motherboard. The RS232 interface is generally via a DB9 connector on the device back panel. An RS232 interface will not work on a serial TTL interface and may damage that type of interface as it...

    DS-2CD2686G2-IZS - 8MP varifocal - Bad 'Ghosting' video artefact

    Just to clarify - Ignoring the high-end models such as the Ultra series that have transcoding facilities, video from attached cameras is simply recorded 'as-is'. The encoding is done in the camera itself using the in-built DSP (digital signal processor) and the resulting encoded video stream...

    Hikvision mailserver problems

    In case it's a name resolution or connectivity problem - As an experiment try using a valid IP address for the mail server instead of its domain name. Enable SSH on one or more cameras, log in and use the ping command in the psh shell against both a domain name and its IP address, to confirm...

    HIK DS-7616NI bricked with new firmware 4.0

    We need a bit more detail in order to help - How are you connecting to the NVR? Is it via a DB9 connector on the back panel, or via a 4-pin connector on the main board? What type of interface are you using on the PC? Is it a serial TTL to USB convertor, or an RS232 serial interface? What port...

    Hikvision RCE Vulnerability

    OK - That would imply you've customised the HTTP port to 8080 from 80. If not - the check will fail. And it would also imply that the device coincidentally has the same IP address as @bashis used in an example. If not - the check will fail. Suggestion : Re-try with the actual values of your...

    Hikvision RCE Vulnerability
