Congratulations, Andy!

Cool. That works! Thanks for the reply.

It appears I can use getConfig to get any configuration, as long as I know the exact configuration parameters. For example, I can get QoS configuration by the following get request: http://ip-address/cgi-bin/configManager.cgi?action=getConfig&name=Qos I will get the following output...

There is a risk to downgrade. See NVR4208-8p-4ks2 after Firmware downgrade - nothing works I have a DHI-NVR4208-4KS2 NVR. I downgraded it from 4.000.0000001.5 to V3.216.0000003.0. Then I ran into boot loop. I had to follow this thread to recover...

Thanks, Andy. Upgraded my DHI-NVR4208-4KS2. So far so good.

I follow this post, Help identifying Dahua OEM NVR from Speco N8NXP, and use eracfg to erase configuration. I was able to recover my NVR.

Thanks for sharing this information. I have a Dahua NVR4208-4KS2 in boot loop. I try the mechanism you mentioned but it doesn't help. Could you let me know which forum you found this information? I would like to do more research.

Test the IP5M-T1179E from Amazon. Its night vision is better than the IPC-HDW4631C-A, but not as good as N22AL12. I wish Dahua has a turret version of N22AL12.

I actually upgrade directly to 16 first. Then downgrade and stay with 15.

After upgrading to 2.800.0000015.0.R, Live view only works with Microsoft Edge. After upgrading to 2.800.0000016.0.R, 802.1x/PEAP stops working.

Has any one tried 802.1x with this camera? I am able to make 802.1x/PEAP working on all my Dahua cameras except SD49225XA-HNR. Authentication always fails.

Thanks a lot for the information. IVS comes back after disabling smart codec.

My NVR stopped working recently and auto tracking of my SD49225XA-HNR also stops. I am not sure if they are related. In post #17, Wildcat_1 mentioned "it can track targets triggered using Deep IVS rules and SMD in cam". However, the IVS option is completely gone from my SD49225XA-HNR when I log...

Do NOT downgrade from V4 to V3. Otherwise your NVR might not be functional! I have a DHI-NVR4208-4KS2 NVR. I downgraded it from 4.000.0000001.5 to V3.216.0000003.0. After downgrade, I notice the following: 1. NVR gets into boot loop. 2. If I power cycle it several times, NVR might boot up...

Are you able to recover your NVR4208 ? I run into the same issue :(

Cool! Thanks a lot for the information.

Upgrade to System Version: 4.001.0000000.1, Build Date: 2020-03-19. UI remains the same. Backup is still missing.

Thanks a lot, UmDaMan. But mine looks different from yours. My NVR is DHI-NVR4208-4KS2. Web Version: V3.2.7.121468. System Version: 4.000.0000001.5, Build Date: 2019-12-06

I have the same problem. By "Backup option", do you mean FTP/SFTP? I couldn't find backup option. Thanks.

I was able to upgrade my chinese version of IPC-HDW4631C-A via web interface without issue. My guess is your hacked non-chinese version firmware prevents you from upgrading. You do know the latest non-chinese version Dahua NVR doesn't support Chinese region hardware, right (I learned it the...

Yes, high wind indeed causes problem. When I mounted the camera at the far end of branch, movement almost never stops. Camera is stable most of time at current position. I will move it closer to the main trunk if I need to further minimize the movement.

I made a birdhouse from fence board, since beepsilver mentioned it. I will put it on the tree next weekend to see how it goes. I might add a front cover to it. Hope no bird will move in ;)

Good point. I didn't think about that.

I plan to bury the cable in front yard directly, since it's a CMXF direct burial UV ethernet cable. I feel a conduit attaches to the tree makes it too visible. Yes, painting the cam is the next thing I am going to do, once I confirm the set up works. Dahua camera comes with a waterproof...

I put a camera on the tree in my front yard recently. The road in front of my house is 25' wide. The camera is located 10' high. I use IPC-HDW2231R-ZS with maximum Zoom and IR. I follow the suggestion from LPR forum to set up the camera. So far it has been working well. During day time, I can...

Thanks, riogrande75. I try your script and it works well. I am able to send myself an email with the snapshot whenever someone rings the doorbell.

Yes. I have Blue Iris record video/audio from VTO2000A. If you have a 12V DC adapter, you don't need the special POE switch.

Never mind. I need to do preset: PTZPreset - Dahua Wiki

I have been using my DH-SD12203T-GN for a while with no problem. Today I try to configure IVS. But I can't figure out how to enable it. When I click on Smart Plan tab, it asks "Add Plan". But there is no plan is available. This is different from all my other Dahua cameras where I can choose IVS...
