    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.

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

    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...

    32 Channel NVR with 16 POE not working

    NVR PoE channels can't be added to or removed, but they can be re-assigned to use a LAN-connected camera instead of one connected to the on-NVR PoE port. Depending on the firmware version, this can be done by either a menu choice in the NVR web GUI, or by changing the channel mode to Manual...

    Alternative way of recovering HikVision NVR password

    When you reset the camera to default settings, did it show as 'Inactive' in SADP or via the browser? I suspect not. That's important for this method. You've originally said the camera firmware is 5.4.0 which is in the range that it no longer has the original default passwords of 12345 or...

    Alternative way of recovering HikVision NVR password

    Not with this method - it relies on the NVR 'Activating' the camera with what's usually the NVR password. However - as you have the current password for the camera, and have been able to extract the camera configuration file, after you've used the camera to pull the NVR password, and therefore...

    HIKVISION mtd Brick Recovery Guide

    Worth noting for those who have a go at this - This isn't the ideal way to run the tftp updater, since connecting the devices directly can cause the extra delay due to link setup / negotiation between the 2 devices to miss the short time window that the camera allows when waiting for a response...

    Camera Issue's After Power Down

    The camera 007 / 003 on your SADP screenshots is showing a 'self administered IP address' as it has DHCP enabled. Untick DHCP using SADP. There is no DHCP server (the NVR does not act as one) so it reverts to a random address in the 169.254.x.x address range. Camera 002 in both your SADP...

    Camera Issue's After Power Down

    Suggestion - as it looks like you've re-plugged the cameras into different ports from where they were originally - In the NVR web GUI, in the Camera Management | IP Channel page (as per your existing screenshot) make a note of the IP addresses and associated channel number the NVR is configured...

    how to recover cameras

    It sounds like you are making progress. If you can reset them, presumably they have a reset button, that's probably the easiest way forward, but you will then need to reconfigure them from scratch. The reason behind knowing that detail was to determine if they have the security vulnerability...
