    DS-2CD2387G2P-LSU/SL - Power Supply?

    Also in the video settings, there is a selection for Video only, or Video and audio.

    Trouble swapping HIK cameras

    You don't need to do anything to enhanced SDK. You need to check the camera IP address versus the IP address that the NVR channel is set to expect the camera on. You can use SADP to set the camera IP address if you know the camera admin password.

    Trouble swapping HIK cameras

    Are you sure that's not just the IP address that the (unspecified) NVR channel is set to expect the camera to be on? Was the new (unspecified) camera in the 'Inactive' state that is needed to be able to be 'Activated' when connected to a Plug&Play PoE port? If not - depending on the model -...

    Wiring diagram for water damaged rj 45

    That diagram is still valid, no reason not to use it, except that - Note - on the later (G1) cameras, Hikvision have swapped pins 4 and 5 (Grey and Purple).

    Hikvision Virtual Host with non-Hik ONVIF cameras

    If your router has the ability to define a static route, you could experiment with accessing the PoE-connected ONVIF cameras directly via the NVR LAN interface. The needed settings are described here ...

    Hikvision DS-7616N-E2 / 8P

    Also - I've just remembered - the E-series NVRs don't support the h.265 codec, just h.264. So worth checking the camera web GUI to see if h.265 is enabled by default.

    Hikvision NVR with HiLOOk cameras (issue)

    On the older firmware, cameras that were activated on NVR PoE ports in Plug&Play mode used the NVR admin password for activation. On newer firmware - Hikvision tried to fix this weakness by providing a separate password for camera activation. That password can be viewed on the NVR using the...

    hikvision 7116hghi-k1 no boot

    The CPU is aborting due to an illegal instruction and unable to run normal code. It is likely that the flash memory is corrupt or faulty.

    Hikvision DS-7616N-E2 / 8P

    Both cameras you quoted are 8MP models - the E-series NVRs do not support that resolution, you'd need a newer NVR model for them. Also - it's likely that the NVR would complain of a 'language mismatch' when adding EN cameras as the DS-7616N-E2/8P (If that's the correct model, ie not...

    Incorrect Time on Hikvision DS-7716NI-E4 After Power Down

    That's good. One problem solved. That's likely a Timezone or DST problem as opposed to an NTP problem. I've seen this way back when a camera handles its own time sync but is also being managed by an NVR, which periodically updates the camera time using it's own values. I don't recall what the...

    Going crazy - POE Hikvision cam works, Amcrest won't - same cable

    This is a managed switch - and while the specs don't specifically mention what port monitoring there is, I'd expect it to show power consumption. That might be useful if it was to confirm that the Amcrest camera was quite a bit heavier on power than the Hikvision one and so was more demanding...

    Going crazy - POE Hikvision cam works, Amcrest won't - same cable

    For some reason (and I maybe just imagined it ) I thought you had a managed PoE switch. Which would provide a PoE status page with power being drawn per port.

    Going crazy - POE Hikvision cam works, Amcrest won't - same cable

    Oh well. Looks like the cable then. What's the PoE power draw with the short cable, with and without your hand over the front of the camera to simulate night mode?

    Going crazy - POE Hikvision cam works, Amcrest won't - same cable

    I think a key test here which should determine if it's the camera or the cable that's causing the problem would be, if possible, to operate the camera connected to the PoE switch with a short length of cable. If it doesn't work - that lets out the existing cable and points the finger at faulty...

    Going crazy - POE Hikvision cam works, Amcrest won't - same cable

    When patched to the router, did you power the camera with an external 12v supply? When on the PoE switch, which status lights show on the switch port that the camera is connected to, compared with the hikvision camera? Do you have a PoE injector or another PoE switch that you can test the...

    Cameras losing privacy mask on reboot

    The password used to activate the cameras will be defined in the NVR, and should be able to be seen in plain text.

    Cameras losing privacy mask on reboot

    It generally works best to set camera configuration settings in the camera interface. These are then picked up by the NVR if the camera is managed by an NVR. Try setting the mask on the camera web GUI and see if it survives the NVR reboot.

    Incorrect Time on Hikvision DS-7716NI-E4 After Power Down

    Presumably the NVR and encoder time values are now correct. Maybe what you saw showed the parameter line format for specifying NTP servers in Linux, such as : To use this specific pool zone, add the following to your ntp.conf file: server 0.uk.pool.ntp.org server...

    Incorrect Time on Hikvision DS-7716NI-E4 After Power Down

    That's not a valid NTP server. Presumably you mean 1.uk.pool.ntp.org Or suggest using something like time.windows.com

    Dahua IPC unbricking / recovery over serial UART and TFTP

    The string appearing won't affect the commands you type, or paste in from Notepad etc. Just makes it a bit confusing to look at, that's all.

    Unless you temporarily change the PC IP address to be in the same range, in which case you will be able to connect.

    is my camera connecting "outside"?

    Unless you are collecting the traffic by using something like a managed switch that's configured to replicate or copy the traffic from the switch port to which the camera is connected (I'm assuming it's wired) to the switch port for the PC that wireshark is running on, you will not see any of...

    Where is the reset button on a Hikvision DS-2DE4A425IW-DE PTZ Camera

    If it's like other Hikvision cameras, the steps are as follows: Start SADP so you can see the camera and its status, presumably 'Active'. Power off the camera. Press the reset button and keep it pressed. Power on the camera. Still keeping the reset button pressed, hold it for around 40-50...

    Configuring NVR (Hikvision) with PoE cameras for a dedicated VLAN

    I would not expect the camera network and other configurations to change when the NVR LAN IP configuration is changed, when the cameras are connected to the NVR PoE ports.

    Getting clear (or not) password from Hikvision Cam root

    Are any of the other cameras older models with firmware 5.4.4 or older? SADP reveals the firmware version. If so - there is an exploit that can extract a plaintext password.

    Getting clear (or not) password from Hikvision Cam root

    I've never attempted to brute-force any SHA-256 hashes, not realistically feasible. If you want to gain access to the camera web GUI etc you can simply delete or rename ipc_db and ipc_db_backup and on the next bootup the camera firmware will recreate the configuration database with default...

    Configuring NVR (Hikvision) with PoE cameras for a dedicated VLAN

    Provided that the VLAN you create will still allow access to the NVR from the (presumed) PC that you are using to manage the NVR, I'd suggest: Change the NVR IP configuration as you've described above. You will then lose access, temporarily. Tag the NVR switch port with the target VLAN. Access...

    7608ni-i2/8p firmware problems now loop booting

    Yes, the Hikvision tftp updater tool has a 32MB filesize limit. Another option to get around that size limitation is to use Scott Lamb's Python2 clone of the tftp updater, from here : https://github.com/scottlamb/hikvision-tftpd

    Getting clear (or not) password from Hikvision Cam root

    That's the Linux access credentials. Depending on the model of camera and the firmware version, the access credentials and capabilities for admin and other users for camera operations are held in a SQLlite database /davinci/ipc_db in hashed form. Here is an example of the sec_user_mana_info...
