I'm having the same problem with the chime, but exacerbated by a setup issue... I originally set up the device using only BCT, and after a few bumps it works except the indoor chime.
So I spent 3 hours today resetting the device and trying to configure it with either of the EZVIEW, HikVision, or LaView apps. No luck. I had in fact reset the admin password as described on the 101 as a bad thing, but I was fortunately able to reset the password back to the default during the reset (I did a power-off and on while holding the reset button, maybe that was the thing that did it), so I don't
think that's the issue. Basically I got to the step of having it connect to the device's wifi and set it all up, and each time it simply said it failed. Checking the wifi AP logs, it doesn't look like it ever connected to the actual wifi network. I have 3 wifi networks, and I tried each of them as options, but no joy.
So in the end, I connected again with the BCT, and re-uploaded the original configuration and it's back to normal (with the same chime issue).
It's a Hikvision camera running the latest Hikvision firmware.
I hope they come out with a BCT update that will allow that setting to be controlled with that
tools.
If anyone happens to be able to set it up from default with mechanical chime, export the configuration file using BCT, then repeat exactly the same except choosing electronic chime (or no chime, whatever) and export
that config file, that might be extremely helpful, I could probably manually edit the config file then I just need to reset the checksum and install it. Could brick it, but why not... I'll be a guinea pig.
