Why is it so Difficult to Produce a Decent Rear View Streaming Camera/Screen?

Garmin has GPS navigation screens that beat smart phone screens in sunlight hands down. There are dozens of companies making micro/mini video cameras. Long lasting, high capacity batteries are now a regular market item. What is it that makes it so difficult to produce a rear facing camera tied to a smart phone size screen so riders can see what's going on behind them and even record it? I followed the promising attempt to produce the Cerevellum a few years back. I'm still waiting for something to arrive. There's a new helmet coming out by Briko but even that will only send the image to a smart phone which is useless in sunlight (so why bother?). If anyone reads this and has news of something being developed, please leave a note if you can.

I have a Longbikes Slipstream recumbent and it's impossible to turn and look over the shoulder like I can on a diamond frame bike. So this is something I feel strongly about. I know about the Garmin 530/830/1030 combined with a Varia but I think having visual information that is real time is the best solution.

Thanks

The Garmins are too underpowered to do it.

Video on the screens would likely look like crap.

A screen that it would look ok on wouldn't work in sunlight.

It's likely a small market that would need a relatively expensive device.

The small cameras don't have long enough runtimes (last time I looked).

=======================

You can do this with a small video camera and a smartphone. You could also plug them into external batteries to extend the life.

But, you probably want something small, good, and cheap. There probably isn't big enough market to do it cheaply. So, you are SOL.

Why wouldn't a bar-end mirror work on the Longbikes Slipstream? Doesn't need to be charged up, runs forever, no need to remember to turn it on or off, no Bluetooth/ANT+ connectivity issues to cause glitches. OK, it may not work as well at night, but you'd still see headlights in the mirror.

A better solution would be a heads up display, an updated version of Google Glass.

Right now that tech isn't cost effective enough for anyone to commit resources to a niche market like cycling.

My solution is to run the best cost effective cameras I can find, front and rear, and to use mirrors. Most rides I run Drift Ghost X cameras front and rear. These came with 5-hour batteries, HD video, tough, weather resistant as-is without special housing, reliable, cost under $100 (usually closer to $60-$70 with discounts via Amazon). It appears Drift is phasing out the HD and replacing them with the Ghost X 4k with 8-hour battery -- more expensive but pretty impressive for the money.

And due to limited neck mobility from injuries I usually ride with a bar-end mirror on my road bikes and Take-A-Look helmet mirror.

Eventually a wearable heads up display and radar/proximity sensing devices will be more cost effective but we aren't there yet. Those will first be developed for larger markets -- motor vehicles, maybe motorcycles -- then trickle down to cyclists.

How are you watching the output from the rear camera as you ride?

Garmin's radar/proximity sensing device isn't that expensive and people seem to like it.

Nope. I use mirrors, same as when operating a motor vehicle. Road conditions and potential hazards ahead are more important than what's behind me.

I don't subscribe to the notion that we should, or even can, "bail out" if we think someone is going to hit us from behind.

I prefer to ride assertively, taking the lane where appropriate, leaving room for drivers to pass where appropriate, and operating my own vehicle or bicycle as safety as I can.

Garmin's radar/proximity sensing device isn't that expensive and people seem to like it.
Yeah, a couple of friends use it. Seems like a pointless distraction to me. It hasn't reduced the perceived hazards. They occasionally post rear videos of dangerous close passes. The main problem is they ride hugging the road edge, inviting drivers to pass unsafely.

Rear facing radar and video won't help. It'll only record the inevitable unsafe passes because they're riding timidly, or choosing to ride inherently unsafe roads. There may be some roads that simply are not suitable for cycling, at least on some days and times of day.

I try to be pragmatic about this stuff. None of it will protect us from distracted or deliberately murderous drivers. I've told family and friends to have police check my video cameras if my dead body is found along the road, so they'll have some idea how it happened.

The OP wants to see the live video. He (probably) knows cameras exit.

You are arguing against yourself here.

I'm not sure if this is a real risk. At "best", it's veeery exaggerated risk (like being hit by a meteor).

If you are talking about close passes, moving to the right a little might keep you from being hit. I think part of the value is just not being surprised.

The Drift app can be used to view the camera through a smartphone in realtime, via the camera's built-in wifi hotspot. It will be laggy and will drain the batteries quickly for the phone and camera. An external battery, cables and secure mounts will be needed to make this work.

A more efficient rear view camera could be cobbled together from dash cams that offer good image quality and electronics in cheaper housings that weren't designed for use on bicycles or motorcycles. You could rig up your own housings, connectors and mounts.

A tablet would provide a more usable screen than any phone. You'd still need an external battery pack and some way to rig up connectors that are resistant to vibration and weather, unless you ride in conditions with predictable weather.
