I'd avoid the LK-7950 for now. It has a known issue when there is a lot of detail in the video (trees for example), the unit has recording errors. I sent mine back and am switching to the X2.
Geoff, this is my exact problem to a tee. Clearly this camera was not ready to be released. I think it is an issue of writing 2 files to the card at the same time. Not sure if they can update the firmware to record front to SD card, rear to MicroSD.
I'll be sending mine back. I ordered the...
Yes, that's with the stock cards, as well as Sandisk. To me, it's not worth the risk of potentially missing recordings on a dashcam. I'll look elsewhere for a dual channel system (maybe Panorama X2?).
I'm having the same "CHK" error while driving. Tried re-installing firmware, using different cards, etc. I think this one is going back to Lukas and I'll purchase something more reliable.
Really interested in this camera (namely video quality) vs. the mobius. I'd like to purchase one or two for road bicycling races. The Garmin Virb and GoPro are incredible, but much more than I want to spend.
Also, can anyone confirm extended battery life via an external usb charger? Most...
If I am only using the lk290 using the "voltage" setting, do I need to use the acc wire as well?
In other words, can I just tap into an always on circuit and ground and still have the unit work when I drop below a certain voltage?
