the camera has multiple voltages in use for different parts, 1.8v, 3v, 5v etc, add firmware into the mix and it starts getting more complex, power supply stability is an important part of the process, I wouldn't have expected the results you were getting from the problem you found but you learn not to be too surprised when things like this turn out to be something you never considered, an odd one that's for sureElectronics is an exacting technology and yet somehow when it comes to digital electronics it's still kinda' part Vooddoo.
Well, yes, nothing is an exact science and all that but I guess in context withNothing is an absolute 100% perfect exact science end to end especially electronics.

Yeah, I think we're really saying the same thing, except that by "Voodoo" I guess I'm referring to an apparently confirmed (so far), but odd result which even you guys find puzzling.Nothing is an absolute 100% perfect exact science end to end especially electronics.
I guess I'm a little puzzled about how you could conclude that the problem I reported might indeed be "a short or broken wire/s in the lead" for the reasons I will try to explain below but either way I'd say it was a good call. Please don't feel that you shouldn't "go up against jokiin & jon" as your opinion is as worthwhile and valuable as anyone else's around here, especially in this case, where neither of them had a good clue about the cause of this oddball problem, whereas you did.I read through both pages of Dashmellow's dilemma and after he mentioned a couple of times that unplugging and reconnecting the lead the GC worked fine until the next failure.
I was thinking to myself maybe there is short or broken wire/s in the lead, but there was no way known I was going to go up against jokiin & jon and suggest it.
Luckily for me I reached the end of page 2 and Dashmellow had located the problem himself.
I have experienced various types of wire connections (not just USB cables) with a break in them many times before, just by moving them a fraction in any direction would make them work.I guess I'm a little puzzled about how you could conclude that the problem I reported might indeed be "a short or broken wire/s in the lead"
I see what you are getting at but at the same time, (as I mentioned above) unplugging and re-plugging the camera also reboots it and as anyone who has ever re-booted a balky computer knows this will often resolve issues or glitches on any digital device, including dash cams. Plus the fact that rebooting the camera by unplugging and re-plugging would consistantly resolve any start-up issues with the dash cam for the entire rest of day even when the USB cable was swapped from the vehicle's power supply to a power bank also made the cable seem a less likely suspect. I would probably have been initially more suspicious of physical damage to the USB wiring if the same issue happened repeatedly throughout the day with each start-up.I have experienced various types of wire connections (not just USB cables) with a break in them many times before, just by moving them a fraction in any direction would make them work.
You mentioned that several times that you would unplug the cable and re-plug it in and the dash cam would then work, that is where I drew my conclusion from, it had to be a wiring problem for my money. I also could have been totally wrong, just look back at post #21 above.
I'll report back, but that could take awhile. Typically, we'll get cold winter temps but they fluctuate quite a bit. Cold snaps come and go but they usually don't last all that long. Then last year, when we experienced one of these "polar vortexes" it lasted for months and just wouldn't let up.The temperature often hovered above and below zero degrees Fahrenheit (sometimes quite a lot below zero) and was accompanied by numerous severe storms with lots of heavy snow. It was brutal! Hopefully this time around it won't be quite that bad but it's been in the news and that's never a good sign.interested to know if it works ok once the weather warms up a bit more, might be a sign of some component that is starting to fail that becomes a problem in the cold conditions
I can try that, at least on a temporary basis. The problem is that I would have to forego using a power bank for parking mode which is important to me. Perhaps I can try it for start-up and switch back to my usual method with the USB-A cable.are you able to set it up using the included power cable for a while, I know we go back to power and memory being the two most common points of failure but I know in our own lab testing not starting when cold has been a problem that could be reproduced with some power supplies and also some memory cards
Thinking about this and considering how the problem has manifested I would have to do this temporary "test" numerous times to know if the SG power supply really was or was not really affecting the outcome and then I still wouldn't be sure until I went back to further testing with the cabling and power supply I've been using all along, all the time having to deal with uncertainty due to the variable of whatever temperatures we happen to experience on any given day. Given the way the camera is installed I would have to remove it from its mount each time so I can have access to unplug or install each cable for each of the two power supplies. Since the problem has been manifesting intermittently all along, going to all this trouble may not even tell me anything definitive when all is said and done.yeah was only suggesting as a test to see if the problem remains or not
Yeah, if I want to use my power bank during my daily travels, it means swapping in a USB-A to Mini-B cable when switching from the Street Guardian power supply to the dual USB power supply. Again, like I said, I'll see how it goes. Who knows, maybe a single test with the original Street Guardian power supply will evoke the issue and we'll have our answer.with a cig charger I would generally just unplug from the socket, pulling in and out of the camera is too much mucking about, was only if convenient, if not then that's understandable
That's new information. Wish you had mentioned this sooner. Yet, all this time (3 years or so) the cam has never balked at even much lower temps. Come to think of it, back in October when this all started the colder temperatures I speculated might have contributed to the issue were nowhere near as cold as it have been recently.the temps are below the rated temp of the processor which it normally deals with ok, maybe as it has aged it has lost some tolerance to the cold starts, hard to know for sure
