Have been given access to the latest production firmware releases.
These are provided to vendors as well as to support cases as they are considered STABLE/tested.
I've uploaded the firmware library for the IPC, SD and NVR series.
These can be found here: Index of /DAHUA/
Excel sheet in the root directory will tell you which version goes with which camera.
Usual disclaimer, use at own risk, if you brick it, follow the recovery thread here: Dahua IPC EASY unbricking / recovery over TFTP
Highly suggest connecting the cameras directly to your PC for updates or disconnecting your Internet connection before hand.
Which leads onto the Best Practice Reminder for those having stability or security issues of late.
ISSUE: 1, Your Cameras are talking to the Internet, either via DMZ/UPNP/Forwarded in the router.
This can cause them to spaz out with too many connection attempts coming from the Internet side, even worse if they have been breeched.
Solution? Block them from talking to the Internet full stop. (Most routers can block devices on the network)
Otherwise look at investing in a proper firewall router that supports being a VPN Server.
Mine can only talk to my local lan and vpn lan, otherwise they can't get out.
ISSUE: 2, You have left the default username/password, suddenly your settings are changing or your uploads are going crazy?
Something in the network is hammering them, maybe some malware living in whatever other devices you have in your network.
Solution? Change the default admin/admin on everything you own. (Modems, switches, routers, printers, iptv boxes, NAS etc and then restart them.
ISSUE: 3, Camera doing strange things? Dropping Out? Lag Accessing the webgui? Video Feed Blocked?
You might be running old firmware, yes the older firmware has more holes then Swiss Cheese...
Solution? Upgrade to the latest firmware.
4, Issues accessing the cameras webgui after firmware upgrades but they responds to pings.
Solution? Camera is getting hammered again but its now blocking connection attempts.
Connect directly to your PC instead of a switch, change it's IP and password, then block it at the router, I suggest turning off UPNP.
Also block easy4ip, it's a sneaky little beast, it ignores being disabled prior to the 2017 firmware release.
if you are running 2016 firmwares then there is a good chance it's calling home. (See network capture screenshot below of a 201610 firmware still calling home after easy4ip was disabled and the camera was restarted.
20161130 and 201612xx firmware is less chatty with easy4ip but I'd still block it from accessing the Internet
If you follow these simple steps, it should resolve 99% of issues experienced.
Re bricked cameras, this would have happened because you attempted to firmware upgrade with the camera still getting hammered.
Solution? Don't do firmware upgrades unless you are directly connected to the camera.
EDIT: I've also uploaded the unofficial firmware source and the MOD firmware created by @cor35vet
