I can tell you a little about the Auto Event Detection parking mode - earlier in this mode, video recording started when motion was detected in the frame, and when the G-sensor was triggered, it was blocked from overwriting and fell into the RO folder. If there was no movement but there was a blow to the auto, the recording did not start. This was the reason for my appeal, and as a result, version V1.1_1010 appeared where, and for only the G-sensor, the recording now starts too.
Those. the logic of the parking mode is as follows:
The recorder enters the parking mode either immediately when the voltage on the ACC wire of the HK4 fails or after 90 seconds - this is configured in the "Enter Parking Mode Timer" menu.
The parking mode works all the time that is set in the "Parking Recording Duration" menu (if set to "Off", the time is not limited), or until the battery drops below the shutdown threshold HK4.
Video is recorded from 2 cameras.
The parking mode is selected in the "Parking Recording" menu, with the value "Off" the parking mode is disabled.
In the modes of low bitrate (Low Bitrate Recording) and low frame rate (Timelapse N fps) - video recording starts immediately upon entering the parking mode.
In Timelapse modes, no sound is recorded.
When the G-sensor is triggered, the current recording goes to the RO folder to protect it from being overwritten.
In the event detection mode (Auto Event Detection) - recording starts when motion is detected in the frame (there are 3 levels of detection, set in the "Parking Motion Detection" menu) or when an impact is detected (3 levels in the "Parking G-Sensor" menu). There are 15 seconds of video buffer BEFORE the event is defined and another 30 seconds are written after the event - in total, each such video is 45 seconds long.
(by the way, this is my current, not yet realized wish - to take the duration from the one set in the "Loop Recording" menu, since 45 seconds is not enough)
