Vueroid S1 Dash Camera Review

I would add that using cheap memory cards, which heat up to high temperatures in the dash cam not from sunlight, but from recording data, increases the heating of the dash cam itself.

Cheap memory cards pose a greater risk of failing to record, or outright not working, long before overheating becomes a problem....

Unfortunately, it's the camera that often shuts down from thermal max, long before the MicroSD. For instance, the Viofo A329 max operating temperature is 65C (149F). A MicroSD can go to 85C (185F), well above what the dashcam can tolerate.

Blackvue's idea of having the dash camerass mount to a central unit that is removed from the windshield would be the most proactive design to mitigate heat. However, Blackvue's trend has not gained traction with other manufacturers.

If DCT is a gauge of dashcam popularity, then the DR770X thread on DCT indicates an appalling lack of interest in the camera, which I suspect is due to its box design rather than its image quality. I had been enamored of these box-style dashcameras at one time, but got over it. They are better suited for commercial and fleet applications than for the casual consumer market. There is a swath of installation factors that involve box placement, proximity to the fuse box, running power if the fuse box is not easily accessible, the extra cable for the GPS, and whatever else may come up. Installation is not geared to the average everyday consumer who wants to install a dashcam.

As far as heat shutting down a dashcam. The bulk of that heat comes from the Novatek CPU, with other components adding their own share of heat. The MicroSDXC card will take a lot of heat before it crashes. The problem is that users demand the image quality of a Sony Venice 2 digital camcorder, but want that ability in a small dashcam that will hide behind the rear-view mirror. There is reality, and then there are delusions. The reality is that this much heat in a small space is problematic. Another reality is that larger DSLRs and digital camcorders also have their own heat issues.

Most of us like the concept of external memory. I will venture that the most reliable implementation will be from a dashcam that uses 12VDC as its operating power, takes into account the length of the factory cable, voltage drop, and heat resistance, and uses a separate power rail and regulator to power the SSD or the MicroSDXC.

Of course, users need to understand that an SSD is a storage device and dislikes constant read/write activities. The SSD, while intended to replace a spinning-platter hard drive, does not offer the same read/write reliability or longevity.

Correct, the main processing unit (Novatek, et al.) generates the most heat, which is why companies dabbled in to creating a separate black box. Industry wide, the CPU and a dedicated GPU (gaming rig) run the hottest on most if not all electronics. The science behind creating black box is sound, but the consumer demand appeared lackluster. Consumers want concealment of a tiny dashcam, but get upset when the dashcam turns itself off on a hot summer day. As Dashcam resolution (4k, 8k, etc) increases, so will the heat generated by the processor. What we then have is expectations not aligning with reality, per your observation.

I am still skeptical that the MicroSD contributes significantly to a dashcam overheating, as the energy output from the card is negligible. Far as using an SSD, either companies could require users to manually select when to copy the MicroSD contents to an SSD, or the process could be automated by a timer if unit is hardwired. Option #1 (consumer) is unlikely, because most people probably have a basic grasp of how to even use the camea, but the option of manual transfer should still be available. Option #2 requires the car be on, and would the data transfer pause existing recording, or could the camera record and move video simultaneously.

Lots of factorys to consider from an engineering standpoint. Still, the secondary storage from an SSD would be quite useful if the process can be perfected.

In my view, that is correct. After disassembling a handful of dashcams and performing surface-heat tests with probes and an IR camera, the biggest factor causing the SDXC to heat up is the controller at the base of the SDXC housing tray. Not the card itself, but the controller, its very short wiring, and the metal housing induce a lot of heat into the SDXC card. That arrangement runs quite hot, and the faster the card and the greater its capacity, the hotter it gets. Some users may notice that a given size and speed SDXC card, when plugged into their computer, some housings will get hotter than others or adapters. I have seen heat differences between two identical USB-C adapters, and even between different-brand adapters with the same speed rating. My personal opinion is that the SDXC card is a minor contributor to overall heat, and in fact, in its dashcam housing, it acts almost like a heat sink.
 
Take several memory cards with different acceptable specifications and let them run in the dash cam for about 30 minutes. After 30 minutes, remove the memory card from the dash cam and measure its temperature. You'll be surprised how hot some memory cards can get. Some can burn your fingers when you remove them. And the temperature from these memory cards is transmitted to the dash cam itself.
This is not an assumption, this is practical experience.

It may not be possible to reach such a high temperature in 30 minutes, but there have been cases of burns from the memory card when it was removed from the dash cam.

When replacing a low-quality memory card with a high-quality one, the problem with the memory card overheating disappeared.

See @lufa6977 explanation. A camera that records at FHD requires a lower class MicroSD than a camera that records at 4k given the need to write larger file sizes more quickly.

Here's a test. Take 3x different MicroSD Cards of reputable brand that are U3 A2 V30 and place them into the same camera, under the same conditions, and measure their temperature after X minutes. It is unlikely that one card will run much hotter than the two other counterparts, because MicroSD use solid state memory. The heat you are detecting is from the controller, as @lufa6977 explained, and from the heat buildup within the case itself due to the CPU.

The "Low Quality" MicroSD cards are using inferior components and are often software written to show a larger size than actually provided. Trying to make an argument based upon these cards is irrelevant, because we're talking normal operating conditions, not user ignorance.

I wrote my post based on real-life cases.
You can believe it or not. That's your right.
 
The most common cause of dash cam functionality issues I hear about on DCT is usually the third party SDXC or firmware, and that's what everyone recommends checking and updating first.

The hottest part of any dash cam is usually located near the SDXC memory card, even when using branded card, Why?
Perhaps it's not the SDXC memory card itself, but its controller, as @lufa6977 noted.
And in the case of an optionally remotely installed SDXC, the controller is also moved in the card reader.

In any case in the dashcam+SDXC/controller combination, both are generating the heat.
And no matter which part generates more heat or less, separating the two heat-generating components benefits both, plus benefit of the stealth aspect.

As for SSDs, this is a completely different and virtually uncharted territory for dash cam manufacturers,
With SDXC available up to 2TB, why invest in something as risky as SSD?
What percentage of dash cam users need to store several weeks' worth of recordings?

An SDXC at 2TB I would consider more desirable than a 2TB SSD at the end of a 3-meter cable.

Logically, it would be a minimal number of consumer-level users who need to store more than two or three days of videos for their protection. I do not know the exact date range for my video files, but I use a 1TB Kingston Canvas Go Plus in my VUEROID S1 4K, and with my driving habits, I am sure I am getting about 6 days of the INV files for the front camera. It is hard for me to say, as I do frequent testing, which sometimes means frequent formatting. With the S1 4K, there are four different Memory Allocations for video and video events, so the date range is quite variable. Anyone with a 256GB SDXC would likely have no issues retrieving a video from several days past.

I think the Max "Officially" supported by many dashcams is a 512GB MicroSD, although I'm not sure if people have tried larger ones?

I do agree that a 2TB MicroSD is far more practical than using an SSD. However, SSD's could serve as secondary storage for the "niche market" wanting more space.

it is very difficult to read and write at sametime with SD CARD. so during copying data from SD to SSD, the Recording should be stop, if the copying want to be finished more shorter.
In case of Remorte SD card, we worry about the reliability of cable. and we will keep following this item.

Yes, read / write at the same time does slow down a card, along with requiring processor power. I would make MicroSD copy to SSD a manual function so that Customer can choose when to initiate the function. You may wish to require hardwire to prevent power source interruption while copying.

100% correct. Files need verified when written to ensure the file copied is a true copy and is not corrupt. You don't want a file to partially copy over and be erased from the MicroSD if the SSD copy fails.

Honestly, I think SSD backup will be a "select" market of people. 99% could get by with a 2TB MicroSD (if supported) and never have a need for the SSD.
