If you have ever locked yourself out of a Hikvision camera or NVR by forgetting the admin password, and had to beg Hikvision or anyone else for an unlock code, you will appreciate this. I present a small tool that lets you generate your own unlock codes which can be entered into SADP to reset the admin password on any of your Hikvision cameras. This tool is written in HTML/CSS/JavaScript so it runs in any modern web browser and you can view the complete source code easily.

////////////////////
Update (September 13, 2017)

It is now possible to reset passwords on some cameras that won't work with the reset code tool, by exploiting a backdoor that was recently made public.

I've built a tool for that. It only works with cameras (not NVRs. If you need to reset an NVR, click here.

GitHub - bp2008/HikPasswordHelper: A tool which exploits a backdoor in Hikvision camera firmwares circa 2014-2016 to help the owner change a forgotten password.



////////////////////

Disclaimer: This tool may or may not work for your camera or NVR. Please follow the instructions very carefully and be precise in all your inputs into the tool. Devices on newer firmware require a more secure password reset procedure which I can not help with. I think this tool will only work with cameras running firmware older than 5.3.0. I do not know what version is the cutoff for NVRs.

Some Hikvision devices (perhaps only NVRs) show their model number appended to the beginning of their serial numbers. You may need to remove this from the serial number that you enter into the tool. For example, if the serial number shows as DS-7208HVI-ST0123456789AAWR987654321WCVU and the device's model number is DS-7208HVI-ST, then the true serial number is 0123456789AAWR987654321WCVU

Without further ado, here is a link so you can use it without downloading anything: Hikvision Password Reset Tool

Some will say it is irresponsible to publish this. I disagree. Evidently a number of people outside of Hikvision have possessed the ability to generate these codes for a while now. I found this (similar) functionality freely available for download elsewhere, so I really don't feel bad about releasing this and making it a bit easier to recover your cameras.

Just tested on my NVR (for no good reason, other than seeing if it worked on NVRs as well as cameras)

In the serial number from SADP, take out the beginning part of the serial which is the model number

Cool, I tried it with a Swann branded Hikvision cam and didn't have to remove anything from the serial. So that must just be a quirk of the NVR.

Are you sure about that? There need to be no errors at all in the serial number, and the year has to be 4 digits ("2015"), month 2 digits ("03"), day 2 digits ("12"), and the camera's internal clock needs to match the date you entered on the form. I do admit though I did not try it with a Chinese camera, only one from USA.

I will try one of my chinese cams when I get home. Maybe something needs to be taken out of the serial number like with an NVR...

Tested on a chinese 2332 and it worked fine. Full serial number, today's date, no trouble at all.

Hi, I have just bought a new DS-7608NI-E2/8P from a Chinese seller, and when trying to log in for the first time it is telling me the password 12345 is wrong. I have emailed the seller for the reset code however have not had any reply yet.

I have tried resetting the password using this tool however keep getting the message password recovery failed. I have tried the full serial number and by deleting the model number from the start.

Has anyone else successfully used this reset tool with this model NVR?

Thanks.
