Is there new firmware for the Dahua DVR-9116HFI-H16? My DVR started running in a loop, rebooting every ten minutes approximately. It occurred after a house power loss but the DVR was plugged into an UPS. I've removed the cmos battery, checked the HDD's, connectors, etc. but nothing has helped.

Over the course of many hours, I was able to track down a file called General_IPC-4300S_Stream3_V2.420.0002.0.R.20140621_a.bin which somehow restores fine both via the web client and the Config Tool.... however this is very old software and the image actually looks very poor from the camera using this version. It also zoomed in the image somehow, I was missing quite a bit of my frame. I wasn't satisfied with this, so I extraced the check.img from this and placed it into several other firmware versions, overwriting the check.img in those, and tried restoring them. Most didn't work, but I did find one image file that did work, and have uploaded a link to that here.

The quick info on replacing the check.img file is that it appears to allow the restoring of different versions of firmware, since it's using the check from the original version that works. You have to use a hex editor and change the first 2 letters of the file from DH to PK, then you have to install Total Commander (zipping it didn't work for me), and double click the .bin file (after you changed it to PK in a hex editor), which will allow you to see the files inside. You do this for both the original firmware that restores properly, as well as the new version you want to restore (that doesn't restore properly), then drag the check.img file from the original firmware to folder in total commander to the new firmware folder in total commander, overwriting the new folders' check.img file with the one from the original folder. After you finish that, change the first to letters back to DH using the hex editor, and restore the firmware using the Config Tool.

I've done all of that already for the firmware file I'm linking here... you should just be able to restore this firmware file and have it update to this newer version of the firmware. The only firmware version I could get this to work with was: V2.420.0005.0.R.20141205 - I found firmware files for 0007, 0008, and 0009, but for some reason when I did these same steps with those, it only seemed to restore 0005. Not sure why, but 0005 is working fine.

I recently bought a pair of Dahua cams, model DH-IPC-HWF1200SP-W and they both lose connectivity quite often. I was in hope that firmware upgrade can help me but I can't find any fresh firmware for this model. I currently have:

gtp, wireless cams are known to be unreliable sometimes. If you have an older router and or a lot of wireless devices connected, that could be it. Before trying new firmware, I would try a factory reset, there should be a button for that.

Unfortunately I already tried all that, i.e. factory reset and also changed the router, but no luck. Weird thing is that I also have a couple of DH-IPC-K35P which work perfectly fine with the same wireless setup. The last thing I decided to try was to switch the power adapters between K35P and HFW1200S-W. They both are 12V 1A but the ones I use on K35P are from factory and the ones I use for HFW1200S-W were bought separately and I hoped they are not giving stable enough power. It is too early to make any conclusions but they work fine for more than 24 hours now. Strange enough that K35P also works fine on the potentially "faulty" adapter. Anyway, if anyone have a newer firmware that I mentioned below please let me know. I also have an annoying software bug which I hope was fixed.

I've seen that website already but I have absolutely no clue which firmware is suitable for my cameras and it is totally unclear from the filenames. I tried opening the description of the files one by one and search for anything related to HFW1200S-W but failed to find one. That's why I posted here in a hope that someone who has such cams already have a new firmware for them.

unfortunately the power adaptor replacement did not help, the camera still looses the connectivity (however, seems to occur less often on the new adapter than on the old one). I also tried to place the camera very close to the router (3-4 m line of sight) but it did not help either. I am still looking for a newer firmware however I doubt it exists. I probably will be able to connect it via the LAN cable which will probably fix the issue but in that case what was the point to buy a WiFi camera... unfortunately I have no option to return or replace it.

just in case anyone will face the same issue. unfortunately I failed to find any newer firmware than the one I have but I found a guy in another forum who works a lot with Dahua cameras and he confirmed that it is a known problem for some of the Dahua models with wifi. the problem seems to be appearing on all cameras within one batch so the only way to fix this is to try a camera from another batch or just use the LAN connection. I did not have an option to exchange my camera so I used the LAN connection and the camera works perfectly since then. 2351a5e196
