Protocol7 posted:It's a pretty great little dashcam, and thankfully not a child. This email is just loving hilarious. Though I don't know why they insist on using a max 32GB card, it works fine with a 64GB Samsung card. The "don't use cards larger than 32 GB" thing is pretty common in cheap dashcams, and the reason probably comes down to Microsoft. The SDXC spec that enables >32GB SD cards requires supporting Microsoft's exFAT filesystem. This is a patent-encumbered system and licensing is required to support it commercially. That said, SDXC and SDHC are basically identical from an electrical standpoint. The SD > SDHC transition required a reworking of how the cards identify their size so it was impossible for a SD device to interact with a SDHC card without a firmware update, but when they designed the new format with SDHC they were thinking ahead as far as capacity. The C_SIZE field is 22 bits long and counts multiples of 512KB, allowing it to support a card up to 2TB. The SDHC spec just said that anything over 65535 was invalid for now. A SDHC device that just doesn't consider large numbers to be invalid would effectively have unofficial support for SDXC cards without having to support exFAT. So basically if they want to officially support >32GB cards they have to pay Microsoft for the right to do it, and I'm sure a lot of these cameras have really tight margins. I'd assume there are a portion of cameras that say that which truly do not support >32GB cards, either due to following the spec to the letter or bugs resulting from a lack of testing up there. I think however that there are a lot more that work just fine with larger cards but are officially SDHC devices for licensing reasons and thus can't officially support them.

Did that other goon who was working on a dashcam project a while back ever end up getting anywhere with it? I gave up on my Pi Zero-based ideas a while ago but have recently been having the itch to work on a project again, especially now that there are a lot of other SBCs in that class now which may be more suitable for the task. In case I missed anything when searching around, is there anything out there commercially that will automatically connect to my home WiFi and offload flagged recordings to my NAS without requiring my cell phone or a cloud service to be involved? There are a lot that have WiFi, but it seems that most of those are for a cell phone to connect and download videos. That'd certainly be nice too, but it's not that important IMO. For me the biggest goal is to keep as much of the card free for the rolling file buffer while not requiring any manual actions on my part. Too often I've found my camera only running one buffer file because the automatically saved recordings filled up the card without me realizing. wolrah fucked around with this message at 21:36 on Aug 5, 2019 |

Takes No Damage posted:Sup bros, just turning right on this red light. What's that? Yeeld? I don't know what that word means... In a some jurisdictions the law says that turning traffic from a single turn lane goes in to the nearest lane unless there are cat tracks or similar indicating otherwise. Even where that's not the law, it's just a good idea. There's no reason your protected left and their right-on-red couldn't happen at the same time, and they'd even have had a full lane of buffer space between, but you aimed for the middle lane and they incompetently took one and a half lanes for a simple right turn. Had either of you stayed entirely in the nearest lane this would have been a non-issue.

Blue Footed Booby posted:Iirc, this changed recently. You can be forced to pony up biometrics, but not passwords or pins. Here's a relevant recent case, and at the bottom of the article are links to discussion of other similar cases over recent years: https://arstechnica.com/tech-policy/2019/11/police-cant-force-child-porn-suspect-to-reveal-his-password-court-rules/ The general consensus of the courts so far seems to be that requiring the accused to disclose their password violates the fifth amendment, but that ordering them to enter the password so specific data can be decrypted may be OK in cases where the existence of the evidence is a "foregone conclusion". Not a lawyer and all that stuff but it seems like when it comes to any kind of surveillance footage the "foregone conclusion" justification by the state would be hard to counter because it'd be reasonably easy to determine what the camera could have seen. --- My personal opinion is that the right balance is to have a well-hidden camera and only bring it up to the law if it's actually going to benefit you. If you've hosed up so badly that they've searched your vehicle and found your camera without your involvement, you probably have bigger problems. I wouldn't use GPS logging in most cases because there are a lot more situations where that can gently caress you than help you, audio varies by your personal situation and what constitutes "eavesdropping" in your jurisdiction. wolrah fucked around with this message at 19:09 on Dec 3, 2019 |

Nitrox posted:when you have WiFi, your phone is the screen. taqueso posted:That post made me realize a way to have encrypted dashcam footage might be making a car pc into a simple DVR for some webcams. For the former, many "industrial PC" or "dev board" type platforms offer a hardware watchdog feature which can help. Basically it's just a simple hardware timer that needs to be reset by software every X period of time. If it is not reset, in time, it trips and resets the CPU causing the device to reboot. Normal PC hardware generally doesn't have this, but the kind of hardware intended for people to build appliances around often does. If you really insist on using generic PC hardware you can also build one pretty easily out of a microcontroller wired to a serial port and your motherboard's reset line, but now you've added another potential point of failure. For the latter, the big issue is sudden power loss. SD cards and the FAT32 filesystem most commonly used on them are both fairly fragile when it comes to interruptions during writes. If a semi truck blows a red and suddenly the battery and alternator are a block down the street, you want that camera to still be able to shut down safely so you can be confident the video is actually saved.. This is why a lot of modern dashcams have supercapacitors, they're a lot more tolerant of the extreme temperatures experienced in cars than lithium batteries.

Krispy Wafer posted:I can't find it now, but there was a car column where the author was agonizing over buying a cheap used Audi A4 wagon manual transmission. I could be getting the exact issue wrong, but I think this model Audi had a plastic timing belt tensioner that was guaranteed to fail and was buried so deep into the engine that the whole thing had to be removed to get to it. IIRC you're thinking of the 4.2L V8, which for whatever fucktarded reason has the timing chains on the back instead of the front, meaning that servicing them is an engine-out job, and of course in true German fashion they used plastic that disintegrates over time for the chain guides.

bird with big dick posted:In a massive impact dash cams typically aren't going to record continuously through the moment of impact, right? They're going to glitch out from the G forces? It is definitely possible to build a dashcam that should not glitch out in any crash that doesn't result in total destruction of the camera itself. How close any given product on the market gets to that ideal is a question we don't have great data for. quote:I have/had a Thinkware F800 Pro and the two video files from before the impact are 36 seconds long and the one video file from after the impact goes back to being 60 seconds long and there's about a 1 second gap in between them according to the timestamp. And there's no reason to power the thing up and connect it to my phone, right? There's nothing to be gained over the files that I've already taken off the card? I would guess your SD card shifted enough to lose contact or the power supply drooped enough that it didn't successfully write. Being a capacitor camera the latter shouldn't really be a problem for your device.

Pressing the button is good if you're lazy, sure if I have something that really matters happen I'm pulling the card immediately but if it's just something little I might totally forget by the time I get home and not think about it until the next time I do pull the card and run through the saved clips. Also if you have one of the older battery based cameras that can't old time anymore it becomes a lot more important since finding anything in the rolling buffer is impossible.

Angle them correctly so that you can just see your door handles, and you'll be fine. If you need to beck up a long distance for some reason, get a spotter. Some part of the mirror should stick out beyond the width of the trailer so that you can see straight down the side. Partial blockage is fine, but if you couldn't see someone peeking around the back of it you need more mirror. The blind spot "shadow" of your trailer should be either straight back or narrowing in to the distance, not widening.

I just pulled the SD card from my A129 Pro Duo and ran through all the recordings in the save folder looking for anything that was worth posting. I found that a significant number of clips had broken video from the front camera with nothing but a static view of whatever was in front of the camera when the car was started. The audio records as normal and the rear camera file is fine, but the front camera clip is just that one frame forever. If there are multiple clips from the same drive it'll be the same static frame for all of them, as if the camera itself is crashing and just dumping the one thing forever. I can then have another clip from later the same day that works fine. Any ideas? I took the opportunity to update the firmware, I did not note which version I was on previously though but it's either whatever it shipped with or whatever was current when I installed it in January. The one constant is that it only seems to happen when my car was parked outside for an extended period of time, but it doesn't seem to fit with the symptoms others report for overheating cameras. I am using this Sandisk SD card https://www.amazon.com/gp/product/B07P4HBRMV/ and an Aukey 30W power adapter.

I have managed to find this thread on the Viofo forums that fits my issue exactly https://www.viofo.com/community/index.php?threads/front-camera-freeze.27271/ That thread notes a significant point that the OSD continues to display in the broken clips over the stuck frame, and overlays itself with every update eventually becoming a mess like what used to happen when you'd drag a frozen window around in Windows 95. This indicates that the problem is upstream of the video encoder, which is then generating and outputting to the card valid video from a bad input. We'll see how a firmware update goes.

The Locator posted:First point of contact was my left rear tire, then moved back to the LR fender. I was able to buff the black marks completely off this morning without too much trouble and can't see any sign of damage behind the fender. You should probably get your rear suspension checked out for any subtle damage, at least an alignment check and a visual inspection on the corner that was hit. Something being slightly off that you'd never notice visually can still add up to substantial additional tire wear at best and of course hidden damage could result in a wheel deciding it wants to be free at the worst possible moment.

GreenBuckanneer posted:Is there a thread recommended dash cam with a backup cam? I've tried a few cheap ones and the ones I've tried can't read license plates because the camera quality is so poor. I have a Viofo A129 Pro Duo, which is a pretty well regarded unit with a 4K front cam with a 1080p rear cam, and it varies from perfectly readable to absolutely useless sometimes moment by moment with the same plate. The video from the 4K camera is usually more readable when lighting cooperates, but each get washed out just as easily if light is hitting the plate just right and a fast moving vehicle can still be blurry. More often than not when I've picked random vehicles to try I've been able to get at least most of a plate from a series of frames, but that takes effort and luck. That's one of the reasons I keep my audio turned on, if something happens and I was able to see the plate myself I'll say it aloud to make sure it's in the clip even if the camera didn't catch it. the paradigm shift posted:on the flip side these rules make no sense for bicycles A good general rule I have for the road is if you do something that other road users have to react to, and you had a reasonable choice to not do that thing, you've probably done wrong.

Honestly I'd have had less of a problem with it had he done this at speed and cleared the intersection before anyone else got there

The power and rear camera wire both loop around the rear view mirror for support before heading down to tuck behind my phone mount before slipping next to the passenger seat to run to the back. The power plugs in to my rear 12v socket since that's switched, and the camera cable goes further back between the back seats before cutting over to the C pillar where I tuck it under the plastic trim to go up to roof level and back to the hatch. I've had "take my headliner down and finish installing this plus my reverse camera" on my to do list for about 14 months now.

It won't be an issue for anything I'm involved in or bad enough to be worth stopping for, but so far I haven't seen any of that. Also this just reminded me I have some clips from the other day I need to retrieve. --- This is why I wish someone would make a camera that had SMB upload support. When I get home and it sees my WiFi it should connect and upload any flagged clips to my network share. I have figured out how to get my A129 to connect to my WiFi but it won't upload anything automatically, the server would need to reach out to it and download the files. Also having WiFi turned on causes some interference on the rear camera feed so I can't just leave it on.

Buff Hardback posted:I’m happy with the A129 but my hybrid has a tiny 12v battery, and I work from home, so parking mode kills my battery. Blackvue has the external battery so I’m going to be using that to solve that problem As for cameras, I'm happy with my A129 Pro Duo but having had it I think I should have gone with the Plus model instead. The 4K front camera doesn't really seem to offer any significant gain in visual quality but it definitely is more sensitive to heat. I haven't had any crashes since the firmware update last year but the forums still indicate a lot more issues with 4K cameras than lower, which is a trend I've also seen in action cams. I haven't noticed any "blurry lens" issue yet even with the car mostly parked outside, I do have the polarized filter installed though so that might help protect it in some way.

I think at this point the A129 and 139 are the default choices you should look at unless you have a specific reason to be drawn to something else. The A129 has a screen on the device and is compatible with most of the same accessories as the older A119, but the A139 supports a third interior camera so if you do rideshare or otherwise might care about that it's worth considering.. The 129 is available in base (1080p front), Plus (1440p front) and Pro (4K Front) where the 139 is 1440p in the base model and 4K in the Pro model. They're all 1080p on the remote cameras. I have a 129 Pro and it has an issue where it'll occasionally freeze the front camera and keep recording audio plus rear, but the front view is just static. It happens most often in hot weather and was more common before a firmware update a few years ago, it's only happened once that I've seen since. Supposedly this is specific to the 4K models, which are also known to overheat in hot climates. 1080p and 1440p models do not do either from what I've found. Night vision is better on the lower resolution sensors. Personally I recommend the 129 Plus by default. I wouldn't say don't get the 4K but I also wouldn't say I think the tradeoffs are worth the higher resolution in the daytime.
