I just installed my A129 and noticed that it shuts down almost immediately after power is removed. No shutdown sound either. I don't have the rear cam hooked up yet.

My A119 would stay up for 2 seconds or so and do a proper shutdown. Is there a way of telling if this was a proper shutdown, or if something is wrong with the capacitor?

The most recent video file seems to be ok, but VLC is good at playing broken files. Is there a way of telling by inspecting the mp4 file, and/or should there be a shutdown sound?

I do not have a shutdown sound on mine and it goes off pretty much right after losing power.

Maybe the A129 is just much faster, hopefully that's all it is.

Too many ¯\_(ツ)_/¯
no sounds is normal, it's just a waste of power, not needed at all, if the files play then it's all good

To me it isn't a waste, it tells me it was a proper shutdown vs battery/capacitor/charger failure. If I don't hear the sound, I know I need to check everything (as I'm doing now).

ok let me rephrase that, when you have a dual channel capacitor based camera you have two cameras to power and more processes going on at once, you can't afford to waste power in the shutdown process

Yes, from a power budget point of view, I understand what you're saying. My biggest fear is that the camera or power supply will fail without me noticing it right away. I'll deal with it, I only posted this thread as I was caught off guard by the fast shutdown vs my A119.

I'll just have to check the files once in a while using the ffmpeg command.
