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
Inside this spoiler block is the complete source code which you can write to a .html file on your computer, allowing you to use it offline.
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.

<div><h2>Hikvision Camera Password Reset Utility</h2></div>
<div class="description">This tool will generate a <b>password reset code</b> which you may use to reset a forgotten admin password for a Hikvision camera.</div>
<div class="label">Enter your camera's complete CASE SENSITIVE serial number, as seen in the <a href="http://www.google.com/search?q=Hikvision%20SADP">Hikvision SADP</a> tool:</div>
<div class="input"><input type="text" id="serialNumber" style="width: 100%" placeholder="Hikvision Camera Serial Number" /></div>
<div class="label"><b>Important:</b> The date you enter below much match with the camera's clock. <b>Most likely it is not today's date!</b> To find out what date your camera thinks it is, power cycle your camera, give it time to boot up, and then refresh your camera list in SADP and check the Start Time column.</div>
<div class="label">Enter the <b>4 digit</b> year the camera thinks it is:</div>
<div class="input"><input type="text" id="year" style="width: 20%" /></div>
<div class="label">Enter the <b>2 digit</b> month the camera thinks it is:</div>
<div class="input"><input type="text" id="month" style="width: 20%" /></div>
<div class="label">Enter the <b>2 digit</b> day the camera thinks it is:</div>
<div class="input"><input type="text" id="day" style="width: 20%" /></div>
<div class="label">Your <b>password reset code</b> will appear below.</div>
<div id="output"></div>
<div class="label">The code must be entered into the <a href="http://www.google.com/search?q=Hikvision%20SADP">Hikvision SADP</a> tool in the <b>Serial code</b> box (called <b>Security Code</b> in later SADP versions). The camera will compare its internal date and time with the date and time you have entered above. The Serial Number and date much match perfectly or else the code will not work.</div>
