Garmin - Dashcam 65W

Yes $230 for 1080p single channel only is rather expensive. I can't even find a equivalent Viofo since the current ones are 1440p minimum. Garmin have a lithium ion battery to provide up to 30 minutes of extra recording when power is out, while most others use a super-capacitor to only close video file safely when power is out. Lithium ion battery are known to not last long in high heat, but I haven't seen Garmin having battery bulging issue. Garmin have their own software with a unique feature that let you sync multiple Garmin cams. Other brands just modify Novatek base software stack, all their apps have similar look and features. Garmin also have lots of accessory options although somewhat expensive, like you can use a suction cup mount instead of sticker mount.

I know 2 guys with them that have been really happy. They are still selling units. There are a lot of action cameras but I went down the rabbit hole and two issues hit most, battery life (I wanted at min 4 hours) and dashcam mode that was useful. I ended up getting the Garmin front (recently) and rear (over 2 years ago) and have been really happy. For me integration to make it easy and on every ride is key. I move them between bikes in 30 seconds too this way.
