Bike Rearview Camera? (Cerevellum seems to be M.I.A.)

With it finally raining (yah!) here in Minnesota, I was planning on buying a rearview bike camera for my commute to work. I'm looking for something that has a screen you can actually see in sunlight, so I was going to go with Cerevellum. (While it may or may not be the same tech, I know my Panasonic fz200 has a "transreflective" or something screen that's 100% viewable in sunlight).

Unfortunately - Cerevellum seems to be completely missing. Their website is up, but it says "out of stock", and searching the internet it's been that way for a while. Looking on their facebook page, their hasn't been a post since December, and it appears that perhaps they did a Kickstarter but didn't raise the funds they wanted. I see complaints about people not being able to get ahold of the company as well.

I tried searching on Amazon, but mostly what I found was "OWL 360 Rear View Video Camera" - but the reviews repeatedly say that you cannot see the screen in daylight, making it pretty much useless.

Wondering if anyone has another suggestion (preferrably something they've used themselves that works in daylight), or has any idea what's going on with Cerevellum...

I've seen people mount rear-facing GoPros under their saddles.

So your plan is to use it as a fancy digital rear view mirror, not to record what is going on behind you? For the latter a gopro would be perfect. As for the former, why not just use a mirror? I know its not as fun/cool, but I would be worried about getting to distracted with a camera, plus one more thing to charge, etc.

Can you connect a go pro to your phone or mount a tablet to your bars?

Thanks for replying, and appreciate the suggestion about the GoPro. I'm looking for something that would mainly function as a rear-view mirror, though.

I've used mirrors before, and I've always been very unhappy with them for various reasons. I find the small mirrors than not using anything, because they give you a false sense you can see behind you but they aren't showing you the whole scene and sometimes I though I'd seen everything but missed another biker or even a car. "larger" mirrors need to mount to the bars and usually my own body blocks my view behind me, particularly since I ride a road bike.

I haven't even liked mirrors on my car until the latest generation where they made the mirrors decently large, even then if my car came with a $300 option to have a rearview camera that showed everything behind me and to my side I would have immediately bought it.

If someone has specific larger mirrors they like, I'd be interested if they posted them, but I'd prefer a camera with a wide angle lens that simply shows me the entire scene behind me in real time.

Hmm, thanks for the suggestion - you can view a GoPro video feed in real time on your phone now? Have you heard of anyone doing this - any idea if it lags or how much battery life it eats from the phone? (Could charge my phone when I got to work, as long as it lasted the ride.) My current phone sucks in direct sunlight, but I've been thinking of getting a new one and maybe I can find one with a better screen...

I don't know if you can, that's why I was asking. But I think you can

Ah, I will look into it more I hadn't thought of that, and come to think of it I think I know someone who owns a recent model I might be able to try it with - thanks!

Thanks for the thoughts so far. I looked into the Go Pro. It has a wireless wifi view you can use with your phone, but the lag time on even the newest model is 1-2 seconds, unfortunately. The Sony Action Cam looks like it's more around 0.2 seconds of lag -
https://www.youtube.com/watch?v=1mWQF1GWnIo

Both cameras seem to have hdmi out with a cable, which shouldn't have any lag, but no phones seem to have hdmi-in - they'll output hdmi, but not display it on their screen. They both seem to have only around 2 hours of battery life - which might be shorter if it's constantly outputting video.

Sony actually makes a waterproof shockproof remote for their camera, but it's pretty small -


Might try it out.

Garmin apparently had a quite solid working prototype nearly two years ago. They already do some rearview camera's for some of their other devices so this was an easy deal for them. Not sure why it's never come to market and if it has or doesn't have record capabilities.

Here is a mirror option that may work better for a road bike
RearViz

I have thought about trying it but have been hesitant with the price without hearing some first hand reviews. I figure I have so far without a mirror just fine.

GoPro with Wifi and a phone could work, but as you mentioned there will be some delay. Also seems like a pretty expensive solution to this problem. Maybe you can find someone who loves to tinker with electronics to build something for you.

My roommate has a camera on his Quadra Copter that sends live streaming feed to his portable DVD player screen or his video recorder. It's a slew of transmitters, receivers and antennas. But it works. I couldn't tell you where to start though.

Just saying... space craft. Some of the most advanced and expensive vehicles in the history of mankind, use mirrors for docking maneuvers. If a billion dollar Space Shuttle is not above using a lowly mirror, then neither is the o.p. IMO. Competition HPV's often get pretty tricked out with high tech innovations because they are mainly designed by college wonks. Often they use video systems to convey information to riders... they fail. Sooner or later. Every time. Often with catastrophic results. Now, some of the most sophisticated race bicycles that might have used video imaging to convey important forward information to their riders use simple periscope systems. For rear-view information its mirrors. Period. Nothing else is as reliable, regardless of cost, and when your @$$ is on the line, KISS is a mantra that you ignore at your own peril. FWIW.

Have you looked at external cameras for your phone?

I just mount two cameras, either both on my helmet or just the rear one on the rear triangle or rack deck.

I think having a rear view camera would be nice if it was cheap and worked in all conditions, and wasn't a hassle to maintain. Better than a wearing a mirror. Would I buy one though? Probably not.
