The doorbell cam I have (I won't mention manufacturer name here) would reboot if the power supply does not meet requirements.
It requires at least a 16V 30VA doorbell transformer.
A 16V 10VA transformer might cause issues.
The doorbell also reports its voltage in the mobile app: 3.9V to 4.5V is in the good operating range.

Somebody here posted they have a 24V 8VA transformer that worked with the doorbell cam being discussed... never heard of that. It's usually a 24V 40VA transformer if you go out to the hardware stores to buy one.

Hey Guys. I just got my DB11 today along with two of the new Starlight+ Cams from Andy from AliExpress. I got condensation on the lens when testing the camera at my front door, but it went away after bringing it inside. Mounted it up and replaced the old doorbell and the condensation is back so hopefully that goes away after it adjusts for a bit to the outside air.

For those who were having issues getting their mechanical chimes to work, go to the settings in the IMOU app and go under "Linkage Chime". You'll want to do "New Association", which doesn't seem terribly obvious but you can set to mechanical in there and enjoy the ridiculous 10 chimes which drives the dogs insane, or go back into the same screen and change it to electronic and it instead engages the chime and holds it open for 10 seconds and then releases for a total of one chime. Downside is on electronic mode it closes that circuit for the 10 seconds and then releases, putting full load on the doorbell transformer, not sure that's good for its lifespan. Also, for those who had issues with an Android device, or even with an Iphone when pairing the doorbell, typically when a wifi connection has no internet the phone will continue to send traffic over cellular, despite being connected to the doorbells hotspot I had to turn my cellular service off and then the App detected the doorbell and I was able to continue with no issues.

I too seem to be having issues with the doorbell overall. Initial testing went fine but my test assistant confirmed audio was kind of quiet and it wasn't super loud from outside but seems good enough to do its job. However after I tweaked the settings using config tool and turned up the bitrate and turned on WDR which is important, now the stream is very laggy in IMOU and the doorbell button no longer works, while the BI stream is still good. Everything has its quirks of course but it seems the DB11 is definitely quirky as others have mentioned. I need to actually work now since i've spent a fair bit of time messing with it this morning, will let it sit and hopefully it will be happy again after being left alone for a while.

EDIT: Guess this was my first post, my cherry is finally popped after perusing the forums for a few years.

"Tweating" the configuaration is not a supported feature which may be causing the issues, that said, I found changing the video stream to "variable" bit rate from the default "constant" fixed my jerky frames which occurred every 5 seconds or so. I haven't needed to change anything else from the default configuration, i.e. WDR, etc. It's producing good images under all conditions.

Has anyone been able to record events or alarms on local SD card. So far I have not been able to. Raised this with imou support team no resolution yet.
SD card is formatted and is detected normal but no video recordings.

I finally got a SD in the DB11. 64GB is the max and you have to format it with MSDOS(Fat). It come with ExFat from Sandisk. Now I am playing with it to record history without buying their Cloud.

How did you manage to record on SD card. I formatted it from the app and it seems in normal mode detected but can't record events or alarms.

Well fellas.. signal drops and ir issues solved!!

First I replaced the transformer with 24v 40va and no difference..
Just tonight inwas thinking the wiring from the transformer to chime and to CBS was 24 gauge.. I ran a short piece of 18 gauge from transformer to db11. 1 hour with ir onnand zero signal drops. Looks like I'm gonna be running new heavier db wire

What firmware do you currently have on it?

i have the same firmware. The Imou app confirmes that this is the latest version. but when i check the Dahua website i found a new one but i'm not able to download it. Here's another link with the downloadbutton. My DB11 hangs himself. I have to hard rest the doorbell and then it works again. I have allready replaced the powersupply from AC to DC but no result.

I'm trying it out. My DB11 doesnt work all of a sudden with 24V. It works if I peel the sticker off the back and plug it in with a USB cord.

How do we get warranty? Through Andy only?

Long shot, but did you give the upgrade process enough time to reflash and boot-up? In the past I've mistakenly thought the DB11 hadn't booted as there isn't any indicator lights when it's powered and initially the ring button will not respond during the boot cycle. I'd give it at least 5 minutes to be sure.

Failing that, you may want to try the SD card firmware recovery procedure as documented here. There's also an older firmware file (dated 20191014) that can be downloaded from here which is worth a try.
