I ended up with the 650S-2CH. Having now seen your F770 review, I may have swung that way instead. But for the most part I'm reasonably happy with the 650S.
- Yeah, the rear camera quality isn't great, but during the day it'll see nearby license plate numbers. I live out in the country, so night driving is dark enough that I don't have high expectations.
- The front camera has lots and lots of dead/stuck pixels. You only notice them with night videos. Obviously inferior quality camera parts.
- The bundle deal included the polarizing filter. Way overpriced for what it is, but it does make a dramatic difference as far as cutting down reflections.
For me though, the main weakness and strength comes from the WiFi/Cloud connectivity. Basically, there are flaws in the implementation. The Blackvue Cloud functionality may impress some people, but is extremely limited. It's basically designed for people with in-car WiFi that's on/connected all the time.
I have mine set to connect to my home router. And when it does connect, all is well. But if I go for a drive and return, it won't reconnect by itself. I have to disable/enable WiFi via the button, or do a power-cycle reset.
The reason this is important to me is, you only have a few limited options to get your videos off the camera:
- Yank the microSD and plug into a PC, which is risky in terms of damage & wear.
- Use the iThing or Android apps to connect to WiFi and do a major song'n'dance to pull the videos. Slow and infuriating poor design, and nearly impossible to get the videos onto a PC.
- Use the Windows Cloud viewer, which requires that you select videos on the camera, upload *to* the cloud server, and then back down from there to your local machine. With my crappy-ass 800kbps upload speed, that's *hours* per video. Useless.
But the good news is that the web interface to the Blackvue cameras is well-known. There are Windows options that, once you're connected, allow you to direct-download video files from the camera to your PC, and just use the Windows viewer app (which is actually pretty darn good). I'm actually working on an app of my own to expand the functionality to auto-download on a schedule. That's just not going as smoothly as I'd like due to the manual intervention required to reconnect the camera to WiFi. I reported this to Blackvue, and maybe they'll update the firmware to make that more reliable.
I mention the above, because I'd like to see more talk of this in reviews of dash cams with alleged WiFi capabilities. I'd love to see reviews answer an simple question: "How do I get the camera videos onto my Windows PC without having to remove the microSD?". I think more coverage of those idiosyncrasies may shape popularity of various models.
