      Sorry to bother you. But been on a problem all day.
      I am new to hikvision. Tried to do a firmware upgrade today on a DS-7216HQHI-K2. Thought all was good until it rebooted. Can not log on? Empty user name. Connected laptop via network cable direct. Adjusted ip. I can ping success. But cannot see DVR. TFTP just says initialised. No other messages come up? Any ideas?
      Thanks in advance

        Sorry - I hadn't seen your previous response. Profile posts don't come up with the usual notifications.
        Glad that you got there, well done!
        That's an unusual trick at the bootloader command line - presumably Hikvision trying to hide something.

        Yes Hikvision hiding away. Suspect they will lock this away further in future versions.... Without reading allot on this site I would not have got this done. Really good stuff to refer to. thanks again...

      I got these values.
      The left hand byte (0x0C) is the most significant byte and should be used in location 0x05.

      The right hand byte (0xС4) is the least significant byte and should be used in location 0x04.
      Then I just replace these values in construction sites 04 and 05, with control figures of what happened?
      1. alastairstevenson
        Sorry, but I do not understand the question.
        That step is to select a specified block of the displayed bytes and calculate the checksum-16 value of them.

      Hello Alastairstevenson! Trying to restore the camera with your video. I’m stuck on point HxD. My camera DS-2CD2432F-IW. Can you help how much you need to highlight the values for my camera? The FF value is 12 and change 02 to 01.
      1. alastairstevenson
        For DS-2CD2432F-IW the value in locations 0x64,65 should show 1298. To calculate the new checksum, select from location 0x09 until the value HxD shows for 'Length : ' at the bottom is F4.
        Then use Analysis | Checksums | Checksum-16 to calculate the new value.

      Hi man, I have a problem with DVR DS-7204HQHI-K1, it absolutely dead, it shows nothing at display. Only power light is on, and i can hear that it powers the HDD but it dosn't show anything at display. I can not find the device with SADP Tool. I have tried doing upgrade with tftp but it seams that the LAN port is not working also, so i cant make the connection. Im really hopeless. Thanks in advance

      Hi, I think you're the subject matter expert on this. Appreciate your help: will I be able to connect ip cameras > PoE switches > NVR (DS-7616NiE2-16P) PoE port directly without passing through the router? Thanks

      Seems like you are the resident expert on Hikvision here.
      I'm trying to help out a friend that bricked a DS-9016HFI-ST, and have only spent about 20 minutes with it so far, I tried to connect to the console (RS-232) port on the back to watch what was going on and saw nothing, the only thing that is not clear to me is if I need a null modem cable or a straight thru serial cable.

      Hi this is my first time posting I apologise if this is a repeat question
      Ive got a DS7608N from China that I bricked trying to update the fw
      I found some Chinese firmware that I managed to load on to the NVR using Putty TFTP USB TTL
      The NVRs working but all in Chinese
      I tried the english version after changing the lang with hiktools in cmd prompt
      So has anyone got fw that will work in this situation
      Thanks Nick
      1. alastairstevenson
        The first thing to try is to ask the seller for a copy of the 'hacked to English' firmware that was on the NVR when you purchased it.

        Thanks for the reply, I've tried to contact them but they never replied. I'll try contacting them again. Failing that is there a way to extract the firmware from another nvr which is working (from the same supplier)

      Hi, this is Jack. I've a question for you, if you can kindly answer it.
      I bought a DS-7732N-E4/16P and I'm trying to update the firmware.
      I tried to change the firmware language (the NI release) using "hiktools lang digicap.dav 2" with no results.
      Can I modify my NVR as I can update it using NI's firmware release?
      Where can I download updated firmware for my NVR?
      Does I was stupid to buy the N version?
