Ok, few comment on the LS430W in comparison with Lukas LK7900 ACE. I was using LK7900 since April this year and bought LS430W a week ago.
1. Instant start of LS430W. After I start the engine and before I buckle up, camera is already starting recording. Amazing! it takes LK7900 about 15 seconds to start
2. LS430W has better video quality. I assume due to the 15MBS bit rate (LK7900 has 11MBS at max)
3. Addition to #2. Night quality for sure is better on LS430W
4. I still want to hear voice confirmation that LK7900 is doing... LS430W does the job silently
5. LS430W has screen... Don't know but i like the presence of the screen. Probably useless during the drive, but useful to check the recordings just after the stop without removing SD card and looking for computer nearby
6. USB and HDMI on LS430W. LK7900 does not have any of them (at least which can be used to access the video files). Basically, I don't need to remove SD card every time I want to check what was recorded.
7. Battery on LS430W. It can work outside the car for about 7-8 minutes. Not much, but personally I like this.
8. Cam attachment. LK7900 has very weird type of attachment, that can be easily broken. LS430W has 2 types of attachments: suction cup and tape mount. Also it is possible to turn the cam right/left up/down very easily on LS4300W
9. LK7900 takes less space and I was able to hide it completely behind the mirror. At least with suction cup it is not easy to do with LS430W. But maybe I just didn't try hard.
10. Display. LS430W has speed and compass, LK7900 has speed and time. I prefer speed and time...
11. It is possible to install CPL filter on LK7900 optics. Very nice feature that is not present on LS430W. But surprisingly enough, LS430W does not have so much glare on video, as LK7900 without CPL filter. LK7900 with CPL - no glare at all!
Still think that both cameras are good, but now prefer LS430W...
BTW, today was -20C and LS430W started without any issues. Waiting for colder weather for testing (just for testing!
)
