A few UI improvement suggestions based on my couple weeks of ownership. These are in order of my perceived value add.
The emergency button is very difficult to get too, especially if it is tucked under the rear-view mirror like mine is. The on/off button however, would be a great, easy to hit, emergency button. A short press could trigger emergency/lock, a long press could turn off. Assuming this button is simply tied to a GPIO, that should be trivial to implement.
I agree with the poster above about the the parking monitor falsing on the door open/close. Perhaps a dead-zone setting option in the parking monitor would be sufficient. A default of +/- 30 seconds from power on/off. This should prevent most door open/close false triggers.
It would be nice to have an indication upon entering/power on if there were any issues during the parking segment. Turning on the screen, and displaying a large number (or beeping) or some other indicator to inform the user that the parking monitor was activated while away. Bonus points if the time/date/sensitivity of the impact(s) could be displayed.
Although, the way mine is tucked behind the mirror, a series of beeps on power on might be a better option b/c it is difficult to see the screen w/o moving my mirror completely out of the way.
And finally, it would be fantastic to be able to use the device as a wifi client on my network. This of course would take a fair amount of effort, but it would be much easier to pull/view videos. Not much ROI on this feature -- it's only neat. Perhaps a compromise would be to auto-enable wifi for X seconds after power so a phone could easily connect and see if there were any issues during the parking segment.
The nerd in me hopes the f/w is still in active development. This is a nice little camera. These updates would be worth a couple of dollars donation.
I wonder if anyone has built a custom f/w for this device?
