    Accessing cams with BI on NVR POE ports

    If the cameras have the NVR PoE interface IP address (usually 192.168.254.1) set as the default gateway, and there is a static route set in your LAN gateway (presumably your router) that specifies the NVR lan interface IP address as the gateway for the 192.168.254.x address range, the cameras on...

    Hikvision camera admin password reset tool

    Does the NVR have new enough firmware that in the VGA/HDMI interface (and the newest in the web GUI) it has the facility to show in plaintext the password that has been configured to 'activate' the cameras on first connection? Don't these cameras have a reset button next to the microSD holder?

    Hikvision UBIFS

    Camera or NVR? Firmware version? Maybe I've not looked far enough, but I've not seen a custom UBIFS in use in the firmware, it just seems standard. What are you actually seeing?

    NVR password recovery or reset

    One thing I'd try is to locate (assuming it exists, which is likely) the 'serial console', which is usually a set of 4 holes together on the main board. These will be 'serial TTL' signal levels, and should provide a command interface into the system controller, the CPU. The method of connecting...

    DS-2CD2342WD-I Password reset

    That's a pity - the 5.4.5 firmware has the backdoor vulnerability fixed that the config file exploit depends upon.

    32 Channel NVR with 16 POE not working

    PoE ports won't show much of a steady voltage on them - the PoE handshake needs to happen before the 48v is asserted. That's not good! Depending on where in the circuit they are, that could certainly cause a fault condition. A bit larger capacitance, and at least the same rated voltage, would...

    DS-2CD2342WD-I Password reset

    That 'password reset request file' must be processed at a Hikvision support system to create the response file - there is no password within it. What's the firmware version of the DS-2CD2322WD camera? If between 5.3.0 and 5.4.0 you may be able to extract a configuration file, which can be...

    Hikvision firmware for Discontinued NVR and cameras

    That error, and the serial number, does suggest these are Chinese region cameras. It is possible to permanently convert that model to the international region that will then allow firmware updates to succeed from the source that you have attempted. It is quite a technical process though, but...

    Hikvision - Clearing Passwords and/or Loading Firmware via TTL Serial

    You need a USB to RS232 adaptor with a null modem interface standard. Totally different signal levels and polarities than serial TTL.

    Hikvision - Clearing Passwords and/or Loading Firmware via TTL Serial

    The RS232 port isn't serial TTL. It's RS232.

    How do ya'll do backups?

    I've 2 NVRs, recording the same cameras. One not very visible, one well hidden.

    DS-KV6133-WME1 (B Version) – Need .dig firmware, received .dav file

    .dav is the usual file extension used by Hikvision firmware. From ages back, it's short for Davinci, a name that's spread around inside the firmware. What makes you think it's a video file? Did you try playing it?

    Alternative way of recovering HikVision NVR password

    Well, that's a good helpful result, at a reasonable price. If you are curious and want to take a quick look, the NVR VGA/HDMI interface camera management page will show what password has been configured to use to 'Activate' an Inactive camera that gets connected in Plug&Play mode.

    Advice request

    That's a current model of Hikvision NVR, I'd expect it to work well with their current range of IP cameras. I'm wondering if the problem is a language or region mismatch. When checking the camera specs, they don't appear on the international sites. Are there any clues in the NVR web GUI camera...

    32 Channel NVR with 16 POE not working

    Just a thought - did you check if the power supply is still providing the 48v that the PoE circuitry needs? If the 48v is missing, that won't stop the rest of the NVR working. Also - the PoE channels each have several 'transient protection devices' designed to absorb or self-sacrifice if / when...
