For existing DDPAI N5 and Z60 user, is it possible to turn off the greeting message every time the dashcam is turned on? Hate all these AI voice beeps and bongs + it sounds a little vulgar

It also depends on the quantum of your claim and your relationship with service advisor/manager,
whatever off the record chat with SA doesn't prevent them from changing their minds when the
rubber meets the road

At the end of the day its's best to ask oneself if that's a risk you're comfortable taking

Thanks. FYI for anyone curious, its under Device Setting > Power On Tone

Food for thought, if you're going with the cigarettes' lighter port the A510 may be a better option.
Both options require hardwiring for parking surveillance feature, however A500 can still record video when a collision is detected when parked as it uses a Lithium battery.
Supercapacitor in DDPAI are only used to transfer file to SD card once ignition is switched off, it cannot record during parking without a hardwiring kit.

All that hoo haa about supercapacitor being able to withstand higher temperature, I've heard of exactly zero cases of dashcam catching on fire and rarely any 70Mai
shutting down due to high temperature.

The HMC1450 battery cost 16 bucks a pop and its super easy to replace the one in A500/510, unlike the A800/810. Can you even find a replacement supercapacitor?

You're right. I set my A800 to switch off with the ignition, and I
could have sworn the dashcam started recording when someone
closes the door really hard, I'm still confused how I got it mixed up.

Appreciate the correction!
