Struggling with parking modes-need real experience advice

[ncpilot]

Planning on getting the A329S 3CH, have been reading all the threads for a week or more... getting close to understanding all the permutations...

Use case: this will be for a strictly pleasure car (Miata for the other couple owners in the forum), local driving/errands. Never plan on parking for more than maybe and hour or two at a time. Top down all the time.

I'm thinking that hybrid low bit rate constant with timeout after 2 hours to LPID would work without killing my battery (I think that's an option)? I'd be interested in all stuff going around outside the car, people possibly walking up to it, etc... or would AED suffice?

I recommend low bitrate mode because you're guaranteed to not miss anything.

The 2 hours on normal car battery is very sensible.

我建议使用低码率停车监控，因为它能让你听到周围环境的声音。无需启用碰撞警报功能，因为这样做会略微增加功耗。

I've chosen to set mine up to capture 1 frame per second video for up to 24 hours after the car is shut off, and this seems sufficient to capture things that happen around the car when it is parked. I've also chosen the 3 cameras in a frame mode so that I don't have to fool with juggling multiple video files. We have good AGM car battery and I've never seen the camera pull the battery down to where there's any problem whatsoever.

With this setting, the videos stored capture 3 hours in each 1.5 GB file. I've captured my neighbors as they walk by. The video frames are like a bunch of still images in a row; there's no blurring. You'll want to make sure you have a video player (e.g., VLC with the E key) that can do 1 frame advances.

Does this not reduce the horizontal resolution of the cabin and back camera files? I'm just thinking in a mall parking lot one would want to keep the highest resolution possible...

I don't think it reduces the resolution. One gets an image organized as shown above, with 4K for front, 2K each for back and interior cameras. I've downsized the above image a lot for display here.

In 3CH Multiplex configuration front channel remains 4K.
All 2K remote cameras are downscaled to 1080p.
All channels have reduced Bitrate.
Multiplex is a good compromise for commercial drivers that need to keep footage for 6 Months or more due to smaller file size.
However, image quality is reduced, (resolution & Bitrate).
If you want maximum image quality do not use Multiplex.
Hopefully the next version of Multiplex will be 4 equal channels in 16:9 aspect ratio with no degradation in resolution.

Thanks for the correction, Chuck. Today I learned that the 2K is 2560 pixels wide, while 1/2 of 4K is 1920 pixels. I blame my mistake on the way marketing named the resolutions.

In practice, there's really not that much difference in image quality, and the payback is quite a bit easier file management.
