Option to upload all, upload flagged, upload flagged plus configurable period before after? I'd pay a lot more than I've paid so far for dashcams for this.

So the A119C is the recommended dash cam? Where is a reliable place to procure one?

Wouldn't be that hard actually. With a bit of setup on a phone app perhaps to link it, I don't see why this would be an issue. One of the cameras I made in the past had a continual, configurable buffer for up to.. 2 minutes-ish. That was back before ram was dirt cheap. The logic is still good though.

I'd add configurability to say "I also want the <x> minutes leading up to or after", as well. The GPS-enabled cameras with speed might sometimes also flag hard braking. The Blackvue DR550GW definitely does.

I'm getting a bit fed up with my Genius DVR-HD500D. It's a front-and-rear dashcam with a display, it records both the front and rear simultaneously, and the rear cam plugs into the dashcam using what looks like a normal headphone jack. What I want to know is, can I buy a front cam from someone else that would accept the video feed from that rear cam? Like is it a normal standard thing, or is it gonna be proprietary and only work with the Genius? The reason I ask is I'd really like to avoid de-wiring all the wiring work I did to get it set up: I've got the rear cam bolted through the headliner with tiny bolts, the wiring running under the headliner from rear to front, and all the excess wire hidden. Failing that, my main gripes with the Genius are: I already had to replace the battery (which could only be bought on aliexpress), the window mount keeps falling off, it gets a ton of noise interference from my alternator (which might be my car and not the cam, admittedly), and now it's just apparently eaten a 32GB SanDisk card after like 1.5 years' use. Also the "night vision" mode is just turning on four front-mounted white LEDs, which is completely, totally 100% useless in a dashcam. Also I think it's not quite a wide enough field of view (130 degrees) - I'd prefer a bit wider, or else mount an extra inch or two back, or something. The usual recommendation is the A119C but I want front & rear recording, a realtime video display, and - this may be asking for too much, but - significantly better build quality and longevity. I'd be OK paying $200+ for a dashcam if it's substantially better quality.

Leperflesh posted:Like is it a normal standard thing, or is it gonna be proprietary and only work with the Genius? Proprietary E: Well, it's probably just power, ground, and a video signal (either composite analog, or some sort of digital signal). If it's just composite, it's not necessarily non-adaptable, but most dashcams aren't going to support plugging in a second cam, and if they do it's probably not going to be the right plug for what you've got. But maybe you'll get lucky?  Leperflesh posted:it gets a ton of noise interference from my alternator (which might be my car and not the cam, admittedly) Might also be the cheap-rear end USB power supply it comes with. If you wired it with a removable USB cable, you might try a name-brand USB charger rather than whatever bottom-dollar thing (I assume) it came with.

Something that records at least front/rear and uses common control/memory. Having a single brain that you could connect multiple cameras to would greatly simplify data collection and upload. Maybe the possibility to expand to side cameras as well, so you can catch when some jackass tries to merge in to you and such. Hell, making it so you have a common control/storage would allow you to reduce of the size of individual cameras significantly, which would give more options for mounting in more useful areas.

Can't comment on reusing the rear camera but Street Guardian is close to releasing a dual camera model, SG9663DC. They're generally regarded as having the best support on dashcam talk forums, and the developer actively posts there.

MikeyTsi posted:Something that records at least front/rear and uses common control/memory. Having a single brain that you could connect multiple cameras to would greatly simplify data collection and upload. This is how my K1S works. The front and rear cameras connect to the DVR via microUSB. No idea if you'd be able to swap them for any other camera that uses the same interface, might be interesting. But yeah, it does mean that the cameras themselves are much smaller than most dash cams. Even people that know I have a dashcam have trouble finding it behind the rear view mirror. Can't do side cameras though. The DVR is a little box that sits in the glovebox, files are named the same with a _1 or _2 after the name it to indicate which camera it came from. It's not without its issues, the audio is terrible, it's not great at night, it's extremely picky with memory cards, and it seems like a not insignificant number of people have reported their DVRs dying/glitching out and having to get them replaced (I also recently had the video apparently cut out at the moment of impact during an accident, I'm still not sure if the impact caused the skip or not but it could be an issue). The Dashcam Talk review is pretty much spot on.

We could use USB-C along with the imx6 processor to handle up to 4 cameras and stitch all 4 of them together during recording. What do you guys think?

I can't find any information on it so I am assuming a DSP or a chineese part.

Separating the camera from the brains would definitely be nice in a multi-camera setup, and I'm definitely in favor of USB-C as the interface. That would also allow for other forms of expansion, like OBD2, or GPS for those who consider it worth the risk.

It also claims the included 64gb high endurance SD card is a $90 value, which lol.

If it's just USB on the camera end, you might experiment with a high quality cig lighter phone charger with a discrete USB cable, just plug it in without routing the cable or anything to see if the noise goes away. But yeah, a big capacitor should act as a decent enough low pass filter, might be worth sticking one across the power input to see if that fixes your existing supply.

Try whatever you've got laying around and see if it helps E: Make sure it's rated for at least 20V! I wouldn't feel safe using a 16V cap for "12V" automotive.

Hey guys; I am writing up an engineering specification for the dash cam right now. Currently, for connectivity features, I have: Wireless - Bluetooth 4.2 - 802.11a/b/g/n 2.4ghz/5ghz - Wifi Direct Wireless will support: - AP/WPA-E/WPA2 and WPS setup. Wired - USB-C Other 9-axsis Accelerometer/Compass/Gyroscope module. MicroSD card reader. Software Features: - Automatic sync to a NAS when connected to a pre-defined wireless network. - User-configurable buffer up to whatever I figure out is the max. - One push button to automatically upload the user-configurable buffer to Facebook/Twitter (to start) using your cell phone to do so. - Automatically flag recordings to prevent them from being overwritten in the case of a sudden shock. (User defined) - Any LED's will be user configurable to turn off or on. - RTSP capabilities. - Easy to configure using a web-interface (Android/iOS apps to follow after release) - Standardized JSON-based API to write your own applets if you so desire. I don't think an LCD screen is necessary for a first gen product. Especially since you will be able to view the camera using any standard player that supports RTSP. This will reduce cost, both in engineering and to the consumer. I will also be using an automotive grade CPU to help prevent heat death. For the second product, I really like the idea of having a central black box to record too that can be placed anywhere in the car. That black box will have 4 USB-C ports on it that will allow you to connect up to 4 Dash cams, and stitch the video feeds together before saving them. As a side note: If anybody is concerned about a IOT dashcam and security, I would agree with you. That's why all of these products will be running Embedded Linux (I'm an embedded Linux engineer), with SELinux, and LibreSSL to start. I take great pride in making network connected things as secure as they can be. I will also have a guaranteed 4 month product update cycle at a minimum, and any major CVE's will be patched as soon as possible. Anything else to add would be greatly appreciated!

Hrm, not a bad idea. It will indeed be USB powered. If I can get away with it I would like to not have a battery in the device if possible. Extreme temperatures make batteries poo poo, and it makes customers poo poo all over you if the battery dies in 6 months even though they leave the thing on with the windows closed in 120F temps.

When you can get a 256GB microSD, that seems kind of unnecessary? The only reason I could see significantly changing the interface is if you are writing so much data that you'd saturate the ~800mbps the card can do, but at even modest compression rates that should be fine. Or am I talking out my rear end?  I just don't forsee exceeding the capabilities of microSD with what amounts to a cell phone camera, even if you have a few

Made a nice drive this past Sunday morning in the Eastern Highland Rim around Center Hill Lake in eastern middle Tennessee. The video is from my Dod Tech LS470W+ cam, in the original 1920x1080x30fps. I have the audio turned off, so no sound. I love to find hilly curvy 2-lane roads to nowhere. Here is 23 minutes of two of them (TN 96 and TN 141) made primarily to demonstrate the quality of the video from the cam. https://youtu.be/WxWB23YHeXk
