5.2.X Modified Firmware: Increased line/intrusion/ROI limit to 4

[DemonicHawk]

2015/10/04 UPDATE: The ROI region limit has also been increased to 4, although I have only been able to get 3 regions working simultaneously. I've also added update-able zips for each version/region so you don't have to tinker with manually replacing the davinci binaries unless you actually want to.

First off, I'd like to say that I am disappointed that this wasn't shared earlier and was instead only shared to those whom were willing to pay money for it - I won't point fingers since I know there's more than a few people who have successfully modified firmware. I have noticed a lot of bright people in this community and we would all benefit from a greater amount of knowledge sharing.

So after spending a few days staring at code, I figured out the changes that needed to be made in order to increase the line crossing and intrusion detection limit. See the bottom of the post for downloads, I recommend flashing the modified firmware through the web-interface or tftp. EN/CH represents your camera region, NOT the language you want. For the technically inclined though, you can manually replace the davinci binary..

Before replacing the davinci binary, I highly recommend looking at the differences between your davinci binary and the corresponding one I've posted. You can do this with a tool called "VBinDiff" on Windows, just remember to extract the binary, don't compare the .tar.gz files. What you should see a total of 12 hex changes - see the attached 525-diff.png for what it should look like. If you see more changes than that, it will probably "brick" your camera when you upload it. I say "brick" because its not really bricked, you just have to tftp to reload the firmware.

I should also note here that if you're manually replacing the binary, my .tar.gz is NOT LZMA compressed, I cannot for the life of me create an lzma archive that the camera will extract properly (If you know how to do this, I would love to know). Thus, you will need to modify the initrun.sh to tell it that the archive is gzip formatted which can be done by running this command on your camera:

sed -i 's/axf davinci/zxf davinci/' /dav/initrun.sh

If you decide to restore your original davinci archive, you can swap 'axf' and 'zxf' to reverse the operation. Having the extraction parameters incorrectly paired with the archive format will also "brick" your camera.

If none of the attached files work for you and you have a Hikvision 2-series camera on 5.2.x firmware, post your firmware or davinci file with some info and I will take a look when I get the chance. If you're on 5.3.0 or up, you will not be able to use modified firmware until someone finds a way around the increased integrity checks Hikivision has implemented.

Thanks for sharing! Just recently updated my NVR's firmware and started playing with line crossing with my cameras, but having one 1 line option was forcing me to keep motion detection too. I'll definitely try this in one of my cameras for now and see how it works.

I downloaded DS-2xx2_v5.2.5_141201_4_line_intrusion.zip file, but I'm getting an archive is corrupt error. Even after re-download.

Thanks, you're right, I tried re-uploading a few times but still got the same thing, I've added a mirror to the first post instead.

Re: 5.2.X Modified Firmware: Increased line/intrusion limit to 4

OK, mirror link worked. Was able to download and extract the digicap.dav without errors. Thanks!

Re: 5.2.X Modified Firmware: Increased line/intrusion limit to 4

I will be looking to adding this into the downgrader if possible.

UPDATE, NOW INCLUDED IN THE 5.30 DOWNGRADER

The things I would like to get working are people counting and face capture.

Unfortunately there are people in this and other forums that want to profit from the knowledge shared here, I could name quite a few.
I'm proud not to be one of them....

Thank you for sharing your find.


Note: 5.2.8 was never released due to and error in the firmware, it was a limited production line only.

I will happily buy you a pint any time you want. Your attitude is one of the reasons this place is great and I hope many others see this and decide to do the same.

I'm proud to join you, but I'm not quite as helpful!

@DemonicHawk, thanks for your great attitude and contribution! Free pint for you when you are in London too!

everything works fine, really affordable 4 line of intersection. Great job.

So after spending a few days staring at code, I figured out the changes that needed to be made in order to increase the line crossing and intrusion detection limit. I hope to post a tutorial/guide of some sort eventually on how to modify the davinci binary, but for now you will find a few files attached below

Great appreciate the time you have spent on this. What would be a great addition is if this could be the start of a firnware that includes other fixes. If it could include the fix to make nas's work better that would be great - I have never managed to get the nas working properly due to this bug? Thanks

Not quite in the same area, but would handy if fixed to work right.

I would be honored if you added it to your downgrader . If you haven't made any changes to the davinci binary, you could just swap them out. Otherwise, I did include a picture in the first post with all of the hex changes that you'd have to make.

I will probably be looking into enabling some other feature in the future, hopefully it won't be too difficult. Just curious though, do you know which cameras officially support all the other "smart" features?

I'm not familiar with the issues with NAS, but if it has to do with the functionality itself, it would probably require significant changes (and therefore extremely difficult)

Re: 5.2.X Modified Firmware: Increased line/intrusion limit to 4

I will mod the binaries over the weekend, well done on this.
The 5.16 firmware was another error release as the some of Smart features were part enabled, these were meant to be just for the 4 series models.

Hi all I'm fairly new to hikvision cameras. I've purchased European cams running 5.3 firmware. How would I go about flashing this modified firmware. Sorry for the noob question.

Re: 5.2.X Modified Firmware: Increased line/intrusion limit to 4

I have updated the 5.30 downgrader with the add on @DemonicHawk and have made note to give you credit for it.

I never look at that .text file before now, it's interesting to take a look at the firmware on the 4 series to compare that file.

This add on is now added to the downgrader in the sticky section using hiktools change the region flag to 1 then just follow the instructions with the updater

As delboy also wrote ''I'm not quite as helpful"" i also feel very guilty somehow because dont have the knowledge otherways would help too. So actually what we are doing is just eating.. So with this message i , at least want to thank you.

I need to change the region flag for non chinese cameras?

Yes as the firmware is set for chinese models, don't worry it won't change the region of your camera, just the header in the firmware allowing it to load to your camera that is all.
