wyze as a cyclist security cam
#11
This guy's Amazon review (a video) shows him using the cam with a phone battery bar thing, and an SD card, which negates the need for a network connection:

No $40 dash cam will do 4K and 60 fps (not even the $250 GoPro Hero 5 Black will do that).

I have a Sunpak 4K camera that was about $50 on sale at Fry's. They go on 1 day sale about once a month in the Monday - Thursday specials.
Currently $70 - https://www.frys.com/product/9315500
I don't know how it would do on a vibration prone bike but I could try if you are really interested. I would need to tune up my wheels and maybe fix a flat, so it could take a couple of days.

The Undoug, you are correct. No internet required. But I would still go for a dash cam.

Found this on SD. $49.99 ends in 5 days. Has a screen. And G sensor protection.

1080P and includes a 32GB micro SD card

The 5s, and presumably the SE will do 1080p/120fps and 720/240fps.

Maybe some will do 1080/240. Get a 'Phone with 128G or more, and you should be covered at either 120 or 240fps for a decent ride.

I have no experience, but I'm betting a higher frame rate at 1080 offers a better chance of not needing the ENHANCE button on your computer, than 4K/30fps, especially when a car is approaching. Then you're at about 900kt closure.

Playback will be a little slow, but grabbing a sharp frame would be much easier.

@ Filliam H. Muffman - sure if you have the inclination.

Can't under stand why 30fps couldn't capture a plate and movement in daylight. I sure would not be pedaling these parts even at dusk. Not when SUVs are doing 45 in a 30.
The cycliq that mattkime has, ticks a lot of boxes and is made for the purpose, though the reviews are mixed at best in a couple places.
The Yi is popular as a dash cam and does 1080@60fps. G sensor, 165º.

Wyze can be USB pack powered according to users and can be time locked by turning on within the network.

You can also install a Dynamo to your bike to provide power to the camera.

Okay, I will look for the mounting bracket and tune up the bike. I use it as a 'dashcam' with a velcro strap to the back of the rear view mirror.

The problem with 30 fps is that the effective shutter speed is pretty low. Any significant vibration or fast panning/motion ends up with the image very blurry. I keep looking for reasonably (sub $150) priced action cameras that can capture over 1080p resolution images with at least 120 fps, but the market isn't quite there yet.

Who said it couldn't? Or wouldn't.

I'm sure there are a lot of circumstances where it could and would.

But I've seen plenty of 30fps footage that didn't capture a plate clearly and one was left to take guesses as to what it read. It some cases, that was good enough. Others, not at all.

You provide police with a copy of the video. What you're reporting, and how much of the plate is legible while have an effect on how far the investigation is prosecuted. A good, clean video or still is worth a thousand words and a conviction. Less than good, clean— not so much.

I don't know how in how many instances 4K would have improved the quality at that frame rate. Maybe some, maybe none. Not to mention there is a lot more detail available at a higher frame rate, as is at higher resolution.

Like torque and horsepower, I bet there's a similar curve between resolution and frame rate where the end sharpness of a frame can be found satisfactory without going to extremes.

This.

The very wide angle of dashcams makes images in the distance appear stable. As they get closer, relative movement is greater and blur can ensue.

And particularly for a bike without suspension (and even in a bike with suspension) the cam will have to be frame mounted for the best results.

At some point I'm going to try my 'Phone at 1080/120. It's a shame that I can't watch it played back at 120fps.
