    New Build for Blue Iris System

    Arguably the 4TB SSD is over-sized for the OS, though it could also be used for video snaps storage, and is undersized for primary video storage, depending on how much history you want to retain. Maybe add a large HDD for the video storage, after working out the aggregate bitrate and the needed...

    Internet Isolation - How important is it really?

    I'm puzzling a bit over what you've described about how the devices are connected. It sounds like the cameras, BI PC, and general-purpose PC are all connected to the unmanaged switch. You've not mentioned a dual NIC for the BI PC, and if so, that would need a separate switch. And I'm assuming...

    Please help Hikvision NVR lost cameras but not all

    A selection of firmware here : https://www.hikvisioneurope.com/eu/portal/?dir=portal/Technical%20Materials/02%20%20NVR/00%20%20Product%20Firmware/04%20I-series/%5B76%2077%2096%20NI-I%5D

    Hik vision NVR Reset

    There is a fair chance it will work OK. I'm hesitant to suggest using the Hikvision tftp updater, which on those old NVRs would likely reset to defaults, as the NVR is a Chinese model and the acceptable firmware would be hard to find.

    Well done for getting there, and sharing.

    R0 / DS-2CD2x32 BrickfixV2 brick recovery and full upgrade tool - enhanced.

    For info - the EN and CN versions of the BrickFixV2 tool have different language settings in the header to cover when the currently installed firmware would reject one with a language mismatch error. And the very latest R0 series firmware is 5.4.800 here ...

    dahua nvr require specific serial cable?

    Have you confirmed that the 'gender adaptor' does not swap pins 2 & 3? If so, either purchase a USB to RS-232 null-modem cable, or a null-modem adaptor for the standard DTE cable.

    dahua nvr require specific serial cable?

    To make it almost like a null-modem connection, pins 2 and 3 needed to be reversed. If 2 goes to 2 and 3 goes to 3 on the adaptor the interface adaptor will not connect to the serial console.

    dahua nvr require specific serial cable?

    Does this mean that the (unspecified) model of NVR has a DB9 connector on the back panel? If so, the 'gender adaptor' must convert the connections of the usual RS-232 serial interface to those of a 'null-modem' cable, in particular swapping pins 2 & 3 around. If you have a multimeter it would be...

    Not getting ONVIF events on Amcrest IP8M-DLB2998EW-AI Panoramic camera in Blue Iris

    To check if a claimed ONVIF compatible camera actually generates ONVIF events, you can check with ONVIF Device Manager. Give ODM some login credentials, top left of the window, and check the Events folder to see. ODM will detect an ONVIF Device automatically.

    *SOLVED* Swann NVR softbricked after firmware update - Currently on uBoot console

    Trying to answer your questions - A manual inspection of the firmware with a hex editor can often reveal a header that indicates how the firmware is packed. And the positions within the file where they are located. Then the tool binwalk can also be used to confirm the main components so that...

    PW reset

    What firmware version are the cameras running? You can see this if you install the Hikvision SADP tool, and connect the PC to an unused NVR PoE port. No need to change the PC IP address. If it's 5.4.4 or earlier the camera password should be able to be extracted, which is usually the same as...

    DS-7608NI-I2/8P recover firmware

    It looks like the tftp command only downloads uImage to memory and doesn't write it to flash. Then the update command still loads the corrupt uImage from flash and fails on startup. So the question is, how to apply the uImage to flash?

    Mean Well power supply for POE+ Switch

    That sounds very thorough and prudent.

    DS-7608NI-I2/8P recover firmware

    Yes, that's to apply a uImage file. Your bootloader transcript suggests the uImage is corrupt. It's guess work which uImage to use not knowing the firmware version, but see attached from the K51 4.1.64 firmware. If that works - but the main firmware is then found to be corrupt as well, see if...
