• Older firmware. Dahua’s download files from 2016 to 2018, which are still online but no longer linked from its site, and RVI’s old file server, with upgrade files for each model from 2012 to 2018.
• Files shared by the community. Firmware posted on forums or shared through Yandex Disk, Google Drive, OneDrive, MEGA and Dropbox. Each file’s page says where it was shared.
• New brands and sources. Sapsan, Vidimost, Hybrone, Goliath and Imou, plus older Dahua, Amcrest and Lorex files listed on Softpedia. ASM and dahuawiki also turned up more files.
• Rescued before it vanished. A Vietnamese KBVision and Dahua download server went offline this month. Its files were recovered from Wayback Machine copies.
• Better matching. About 800 more files are matched to the hardware they run on, nearly 7,800 in all, and almost 900 more retail model names are listed.
• Cut-off copies point to the full file. Some files turned out to be just the start of another file. Their pages now send you to the complete file instead of offering the broken copy.

As always, new files appear on Newly added, and flashing firmware is at your own risk.

• More places to find firmware. New sources include Global DS (Hungary), TVC (Mexico), SNR, Lupus Electronics, Sveistrup, Santronic, BITS, Winco, Security Point (Italy), Dahua India, the Eltrox family of brands (Kenik, EasyCam, Notis, Zeus, Irbis and Konig), and community collections shared on IPCamTalk and ip-phone-forum.de. Dahua’s own servers also turned up older builds that are no longer on its download pages.
• Saved for good. Almost every file now has a permanent copy on the Internet Archive, so it stays downloadable even after a vendor removes it.
• Better matching. Nearly 7,000 files are now matched to the hardware they run on, about 1,000 more than before, and around 1,000 more retail model names are listed.
• Clearer labels. Firmware that can’t be read is now explained instead of marked as failed: encrypted firmware (common for newer recorders) is labelled as such, and microcontroller firmware, which updates a small part like a PTZ motor controller rather than the device itself, is marked separately.

As always, new files appear on Newly added, and flashing firmware is at your own risk.

• Many more brands. Dahua’s own download sites, plus EmpireTech, ENS Security, Inaxsys, VIP Vision, Rhino, Montavue, RVI, Speco, Optiview, IC Realtime, Intelbras and others, and distributor download servers in Europe and Ukraine.
• Rescued firmware. About 800 files that their vendors no longer offer were recovered from old copies saved by the Wayback Machine.
• Better matching. Nearly 6,000 firmware files are now matched to over 6,000 devices, so it’s easier to find firmware for the same camera sold under another brand’s name.
• Know your chip. Many firmware pages now show the chip the firmware is built for, and you can browse firmware by chip.
• Safer flashing. Firmware pages warn when installing a file may stop you going back to older firmware, flag incomplete downloads that can’t be installed, and point out Hikvision firmware that some vendors list alongside Dahua’s.

Some firmware still can’t be analysed, mostly encrypted recorder images, and a few more downloads are on the way. New files appear on Newly added as they arrive.

• Retail models by brand. Pick the brand that sold your device to see its models. Brands with thousands of models, like Dahua, are split into series such as IPC-HFW or NVR.
• Shorter pages. Long lists of firmware, on device, chip, brand and year pages, are now split into pages of 100, newest first. Brand pages show their newest firmware and most common models, with links to everything else.
• More detail where it helps. Firmware pages can now show the chip, Linux kernel and flash layout, and list the earlier addresses a file was published at, which helps when hunting for copies.
• Faster loading. Brand logos are smaller and load only when needed.
• Old links still work. Pages that were merged or retired now forward to the closest current page.

• A page for every firmware file, showing who publishes it (vendor sites, mirrors, or Wayback Machine copies), the retail models each vendor sells it as, version, release date, size, checksums and changelog.
• Permanent downloads: where a file has been archived on the Internet Archive, that copy is offered first, because vendor links break.
• Clear warnings on firmware that is truncated, can’t be downloaded, or isn’t Dahua firmware at all (some vendors also sell Hikvision-made devices).
• Device pages built from the hardware IDs inside the firmware, so you can find every compatible file, whichever brand published it.
• Retail model and vendor pages, with each vendor’s current firmware listed first.
• Search for models, device IDs and file names, right from the header.
• Newly added firmware with an RSS feed, plus this changelog.

As before, flashing firmware is entirely at your own risk. See why this site exists before you start.
