All the other Dahua cameras I have installed had the ability to format the card, but I am guessing this is different due to the lack of a web interface?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.

FWIW, the above factory reset procedure with holding down the reset button while power cycling did not work to reset my DB-11. I tried it multiple times. What worked was holding the reset button for about 5 seconds until dark blue light came one, then releasing and hitting it again to start the hotspot (this is also whats in the manual). Power on the whole time.In the event I needed to factory default the doorbell, the smart switch would allow me to perform the operation myself versus recruiting a <complaining> family member to either hold the button on the back of the camera or power-cycle the breaker.
Mine did not let you format in the iMOU app unless it is MS-dos(fat). ExFat could not be recognized by the DB11 on a 64 or 128GB Sandisk Ultra micro SD card.All the other Dahua cameras I have installed had the ability to format the card, but I am guessing this is different due to the lack of a web interface?

I was able to factory reset by holding reset down for 20 secs when powering on breaker. Then you have to press momentary to get the DB11 to broadcast on its wifi to connect and reset up the doorbell using IMOU. Again I verified if power goes out then you have to get it working again by momentarily pressing the reset. Luckily the capacitors held the doorbell up for about 20-25secs. This is good as our Generac is set to come online 10 secs after a power failure.FWIW, the above factory reset procedure with holding down the reset button while power cycling did not work to reset my DB-11.
