I'd install this hack and it work fine (V0.95). Everything looks great!

1.May I play some alarm voice on it?

2.Any startup shell command? or just append some script to script/function.sh.

3.Where can i find the motion logs or any way to fetch motion status?

Thanks.

Hi @ghoost82 You have done a very interesting and outstanding job, my mijia-720p(software version:3.3.6_2017092710) is perfectly run.

At the same time, I would like to ask what is the principle of this hack. I noticed that the device file is mounted like this

Filesystem                Size      Used Available Use% Mounted on
/dev/root                 8.6M      8.6M         0 100% /
/dev/mmcblk0p1           28.8G     50.0M     28.8G   0% /mnt/media/mmcblk0p1
/dev/mmcblk0p1           28.8G     50.0M     28.8G   0% /tmp/sd
/dev/mmcblk0p1           28.8G     50.0M     28.8G   0% /tmp/sd/ft

How did you make your custom script load before the product firmware?

In addition, the ssh host key changed new one after the mijia-720p-camera restart, is normal?
