    Here is the manual: https://www.dahuasecurity.com/asset/upload/product/20180709/DB11_Users-Manual_V1_0_1.pdf

    Here is the spec sheet: https://www.dahuasecurity.com/asset/upload/product/20180709/DB11_Datasheet_20180621.pdf

    We are off to a better start than with the Db-10 video door bell. Keep in mind, So far this is based off of the DB-11 residing about 3 ft from my wifi router.

    As I don't have a traditional door bell, I'm testing this using a 24vac transformer.

    The following works as it should:
    • Adding to the Lechange app.
    • Manual Video viewing: both SD and HD
    • Audio during manaul view-talk and listen.
    • Audio Quality from the door bell speaker is MUCH better than DB10....still very low volume.
    • No batterys!
    • Motion detection alerts, with actual recorded video.
    • SD card is recognized and can record to the card (same exact SD card the DB10 still doesn't recognize)
    • Pressing the door bell button, alert comes to phone.
    • Pressing the alert on the phone, brings up video from the Db11.
    Here's where things go a little south. When answering a call on the phone, out of 10 test calls, 3 times I received the error that "Audio Failed". Video still streamed.

    We'll see what happens when I move this out by the front door.

    Well there is good news and not so good news.
    • When motion is detected in the dark, it takes 4-5 seconds for the IR to turn on, that's too long IMHO.
    • My wife and I agree the "door bell" button emblem does not stand out well enough, and most people won't see it to use.
    • Dahua Configtool finds it
    • You can adjust "some" of it's settings with CT
    • SmartPSS doesn't find it, but it can be manually added.
    • I can view live video in both and with my phone.
    • While messing with SmartPss, and changing settings in the door bell, the DB11 crashed.
    • Took two hours of futzing around deleting it from Lechange, Adding back, Resetting to defaults, etc. to get it to come alive again.
    • I have it added to BI, see screen caps below.
    • Audio works in BI
    • It does have RSTP.
    • Door Bell crashes and reboots while live viewing video every 2.5 to 3.25 minutes. No matter what method I've use to view. Takes about a minute to come back online.
    • This is all with the router within 3ft of it.

    I captured this video via BI between crashes. Sorry for the IR glare, this is setting on my water softener, and the IR is bouncing off the lid. There is no glare when properly placed.

    Whew! Good thing they included a screwdriver, right @looney2ns ? :highfive:

    Thanks for taking time to do the review and post the pictures.

    Can you clarify:
    I see no mention of ONVIF compliance, RTSP availability, or BI compatibility, right?
    Am I correct in stating that it's cloud-based and one needs to have (probably) minimum of 4.0 Meg Internet download and upload speeds, right?

    I wonder if it would have been possible for Dahua to enclose a battery-backup option, should the wires ever frail

    But on the other hand, good to see more competition, no need to depend on cloud-based services here

    Myself, I really enjoy the bubble level. ;)

    I will do some more digging and get back to you.

    It can be used as cloud based, but if you put an SD card in it, then the videos and alerts can be saved to the card without a cloud account.
    But, you do have to install the LeChange app, and link the DB11 with it, that leads to no port forwarding or such.

    @Arjun if installed correctly, the door bell wires should out last you. If you want battery backup, then get the DB10.

    Message #2 has been updated with video and more info.

    Also, the Doorbell works with the Lite NVR I have here. But, the DB11 still has the reboot issue.

    @looney2ns Thanks for doing this review.

    Does DB11 crash if I live view via UI3?

    Oh I just saw the update in Post #2, ouch ... maybe Dauha need to move away from the doorbell business and stick with wall mounted cameras. It not having a good track record with doorbell so far.

    As usual, thanks for your hard work for the review, @looney2ns .

    With regard to "....My wife and I agree the "door bell" button emblem does not stand out well enough, and most people won't see it to use.",
    I agree as well and offer the following suggestions to Dahua, should they care to check with this forum. It employs the noted "wet paint" phenomenon, wherein the reader of such a sign feels compelled to touch the wet paint. I have included an International (or illiterate?) version and an English version. To avoid offending any more folks and for the sake of brevity (not one of my stronger suites), I did not include the Italian or Polish versions.

    NOTE TO DAHUA: This is a joke! :p

    Hopefully Andy is drawing Dahua's attention to this thread.

    My first thoughts at seeing this is unlike most doorbell cams, the daylight quality looks very good. Night time, once the IR is on and the camera adapts (BOTH of which take some time), it's decent quality if not groundbreaking. However, as pointed out the IR takes too long to come on and for me, the time taken for the camera to recognise it and adapt is too long also - I make it around 9-10 seconds in total using the video timings, which is more than enough time for something to happen. It would be good therefore to see both improved IR switching and adaptation times, the latter especially, as using your timing of 4 secs for IR, that leaves an even worse time of 6 seconds for full adaptation to the new lighting source.

    Hopefully the rebooting issue is something that can be quickly fixed with a firmware update. Seems ok except for that issue.
    You said you are powering via a doorbell transformer, but don't have a doorbell right? Perhaps an issue with that? Not likely, but... Do you have a DC source to test with?
    Just a thought.
    Thanks for testing.

    if talk does not work with standard settings, try the dahua 2320 option from the dropdown.

    The doorbell is powered by transformer, the ir light should be on the entire time. No reason to shut it off.

    Agreed. Unless the device is overheating with IR light and recording on, there is no reason for this. That would solve slow ramp up and image adjustment issue. Fix rebooting issue with firmware and Dahua has winner.

    It's not a doorbell transformer per say, it's a plug-in 24vac 40va supply. Actual measurement at the door bell terminals is 25vac.

    I dug around and found a 12vdc wall wart. I'm now using the 12vdc supply and in the dark, and viewing live same results goes offline in 2-3 minutes. But with the garage lights on, and no IR, It's now been streaming non-stop for 57 minutes. That's a huge improvement. So, it does appear that the IR lights being on, and pulling a stream, cause's it to wig out. By the way, the temp in the garage is around 85F.

    There is a status light above the door bell button that stays lit all the time, and goes out for a few seconds when it goes off line.
    So, I sat in the garage last night, with the lights out, and sat still so the motion didn't detect and IR was off. I watched that status light for 30 minutes to see if it went offline, and it never blinked. I'm took one for the team here. :)

    I'm going to move it outside by the front door today, and see how it goes.

    @looney2ns Thanks for going the extra mile. Can you confirm that your wall wart can delivery sufficient amps to the DB11, especially when IR is on. Perhaps, DB11 is rebooting due to insufficient power?

    The wall wart now in use is rated at 1.5amp. Specs say DB11 pulls <4 watt max.
