I have a dashcam video I want to post, but it has (a) a coworker's car visible (and he asked that if I upload the video, to block out the license plate) and (b) another coworker's face visible (road rage passenger screaming at him and pounding his window :stare:).

Anyone have suggestions on easy ways to blur out a face and license plate? Let's pretend I have no experience with video editing except for trimming clips and joining clips...

Absolute quickest & dirtiest is uploading the clip to play on a big screen, then recording it with another camera while floating a piece of cardboard attached to a chopstick over whatever private data you want to obscure.

It'll have the "filmed off the CCTV video monitor in the back room of a Burger King" type of vibe and everybody is gonna make fun of you for how awful it is, but honestly at that point nobody is gonna be able to make out a plate number or face regardless if you try to cover them up or not

Are encrypted Dashcams a thing? In an ideal world whatever I recorded would only be accessible by me (absent a court order). I like the idea of capturing video to cover my rear end, but not a big fan of capturing video in the odd event that I do something that actually is incriminating by mistake.

The fifth amendment is only about giving testimony, not "evidence". Also, if the thing you don't want them to see is worse than the charges for refusing to hand over evidence, then it could make sense.

Of course the real answer is, don't break the law while driving, whether or not you have a dashcam. If you drive responsibly, the dashcam is far more likely to help you out than it is to incriminate you.

Courts have ruled in a variety of ways on these sorts of things over the years depending on the situation, and so far most of the decisions have been at the state or district levels so they technically don't apply entirely to the rest of the country (though obviously courts do tend to respect precedent from other courts where applicable).

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.

I've been awake nearly 24 hours, and really don't want to stumble 2 buildings away to my garage to yank the dashcam. :v: I'll try to pull it overnight. I'm not even sure where my microSD card reader is right now..

It's honestly not that interesting of a video, it's more the audio that's interesting. rear end in a top hat CW jumped out of my car, stomped up to the passenger window of another coworker's car (also being an rear end in a top hat by stopping in the middle of the aisle to block us in), pounded on his window, and started screaming at him about being late for his therapy appointment.

The screaming about a therapy appointment is what makes it hilarity, though you can hear me and another coworker cracking up. Dude has some serious anger issues, and I probably won't be giving him a ride again in the future. He didn't do anything to me or the car, but the level of anger I saw over someone being an immature dick was kinda scary. (he doesn't drive... takes the bus to/from work, lives in one of the shittiest apartment complexes near work... despite making $45k+/yr stocking shelves).

e: goddamnit. now I WANT to stay up to edit and post the video, but I have no clue where my card reader is. Both parties told me they don't want it uploaded, but hey, one party consent state (I let rear end in a top hat CW know about the dashcam on a previous ride), video in a public area (parking lot), and I'd be blurring out the license plate and faces. The only way you'd be able to identify anyone after that would be if you (a) recognized the parking lot and (b) worked overnights at my store.

Pretty much yeah. I just don't know where the gently caress my card reader is; I use it maybe once every couple of months.

Worst case, we wait until I get paid again for me to go get another USB card reader. The camera doesn't show up as a USB device if I plug it into the PC, it's strictly power via USB.

It does have wifi, but it's essentially dialup speed (it takes ~10-15 minutes to transfer a 3 minute clip), and the app doesn't seem to play nice with Android 10 - at least, not my particular phone. The phone keeps forcing itself back onto mobile data once it realizes "oh hey this wifi AP doesn't have the internets", unless I force the phone into airplane mode and enable wifi by itself. My phone is also a special loving snowflake (Essential PH-1) from a company that only made one phone ever. :sigh:

The battery on the camera is also trashed, so I have to sit in the car with the key on to do that (the camera also requires a 1.5A power supply, so your typical 500mA-1A wall wart will cause it to power cycle - luckily the USB connectors on my head unit put out 1.5A/each without needing to negotiate Quick Charge or anything, only reason I was able to ditch the included cig lighter power supply). All of the wall warts I own that are capable of putting out over 500mA require some form of Quick Charge or Power Delivery protocol, otherwise they default to 500mA. When I first got the camera, I could easily get 30 minutes out of the battery; it shuts off with a low battery warning about 5 seconds after shutting off the car now (instead of recording for an additional 60 seconds).

TotalLossBrain posted:

Tried it with multiple micro USB cables, same result. Doesn't show up as a mountable file system, or any kind of device - it just starts trying to power up over and over again (since a PC USB port is limited to 500mA....)

It was a great dashcam a couple of years ago. I'm just too cheap to replace the fucker until it starts corrupting the card when I shut off the car. At least right now, it pops up a low battery warning immediately after shutting off the car, and does a graceful shutdown (usually). It'll corrupt the card once a month or so, always when it just turns off without showing the shut down screen.

tl;dr Anker makes great cables and battery packs, their dashcams not so much...

Just FYI, a microSD card is very small and easily swallowed. Not your fault you didn't have a card in your dashcam when you used your car to tenpin bowl a Klan meeting.

I've had to show dashcam video to cops a few times. It was always with my old G1W, which had a horrible screen. Thankfully, the one time I actually got in an accident with it, I had a tablet with me that had a microSD slot. The other driver claimed I ran a red light, and slammed into him doing 60+. It was a protected left turn with 2 lanes turning, and he took it wide with me in the outside lane. The cop was already asking him to repeat it (and to write it down as an actual statement, probably so he could nail him with giving a false statement), because the damage from a Saturn slamming into a Lexus at 60 MPH would have put at least myself in the hospital, if not the morgue. Instead, my car got the front bumper refinished, and they needed a new rear bumper and reflector. IIRC the total repairs on my car wound up being about $700, plus a rental for two days. That's not a repair bill you get from a 60 mph collision.

The only other time I remember having to show a cop the video was when I called in someone that was ping-ponging from curb to curb (on an 8 lane road - 4 each way - 50 mph road, he was doing 15-20ish IIRC). The cops didn't catch up until he'd parked at a drug store and gotten out of the car, so they couldn't do anything unless they had proof. The dashcam showed everything, including him pulling into the store, parking (across 2 parking spaces), and falling out of the car. Despite the terrible screen, they basically said "yeah, that's all we need for an arrest... can you email us the videos for whenever he goes to court?". The cops later told me he had taken Seroquel (an antipsychotic that's also used off label as a very powerful sleep aid).

That why I buy dash cams with screens for anyone over 50 years old. For everyone else it's wifi directly to the cell phone.

My trick for getting that video quickly, is to disable mobile data on the phone so it doesn't get confused and connects directly to the camera. But maybe brand of camera makes a difference, I don't know. The B1W bluesky app is simple, stupid but functional. $60 well spent

So I picked up a cheap Aukey GRA1 from Amazon the other day as it was on sale, ran it with the cable just hanging down for the first day to test/work out positioning etc. I tucked the cable around the edge of the windshield yesterday and now my SiriusXM reception is terrible. I unplugged the cam from the lighter socket to see if it was interference, but it seems the actual presence of the cable in that area is causing it, and that must be where they run the antenna in my car (‘10 Corolla).

Do I have much option other than having a cable hanging there, or having to go back to FM?

Yeah, that was Nitrox's point about the over-50s. For someone who can handle using an app, your phone offers a much better screen than any standalone dashcam has ever been equipped with at the cost of a very small amount of latency (so when positioning you might have to tweak it a bit and then wait a fraction of a second for the display to update).

The trickiest part about any kind of DIY solution is handling crashes, both the internal software kind and the external vehicular kind.

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.

Supercaps have a few benefits beyond temperature. They don't wear out like batteries, and they are very lightweight so it's much less likely to rip off the board in a crash situation. And they don't need any special charging circuitry like batteries that aren't lead acid.

Worth trying the increase before a new card, it’s just as likely a case of optics rather than resolution. Heck it might even be upscaling to the higher res.
