Hate it that you’re having problems, but at least you’re seeing them firsthand which is beneficial as far as your reviews/recommendations.
Yeah that definitely helps. Even if I didn't see the issue myself (I live in a cooler part of the world than many of you guys), it's really helpful hearing your experiences as well so I have a lot more datapoints to reference and we have a better idea of reliability across the board.

That's what happens when you talk nice about something in your video. Stops working. Nice one. Haha

That stuff really bothers me.. to find something I like and recommend, only to find that we start discovering issues once we get them. It's one of the reasons I try to do a lot of testing, research, and discussion beforehand. I still haven't done my full review video of the dashcam. Just a quick overview video with some sample footage and going over the differences from the 750. After I finish up my next round of dashcams to test and review, I wanna do a full review of the 900 with details like this and information from Blackvue as far as their take on the issue. It's all part of the process.

The only solution is to "not not" recommend something

I'm chatting with Blackvue about the overheating issue now. I sent them a link to this thread last week so that they can see that a number of you guys are experiencing it too. It doesn't look like too many people have reported the issue to BV yet (which surprises me a bit) so I'm glad that you guys are sharing your experience. It helps them figure out whether it's limited to a few copies of the dashcam or if it's more widespread.

Something that I just found out when they asked me about it, a few seconds before the dashcam shuts off, it'll say "HT" at the bottom where it would normally say "NV" when you have Night Vision enabled. I presume that stands for "High Temperature" and that is basically an error message to confirm that the subsequent shutdown is heat related.

To those of you guys running 4K and H.264, are you seeing any overheating issues?

It turns out that the DR900S has a chip inside that allows it to do hardware encoding for H.265 so while there is a slight difference in processing power when jumping from H.264 to H.265, it's not much. Nevertheless, Blackvue is wondering if running at H.264 would help resolve the overheating issues and I'm curious to hear what you guys' experiences with that is.

Wouldn't that significantly increase the file sizes?

IIRC, the file sizes stay the same, but the quality will be reduced. Either way, the main question is if a less intensive encoding scheme would allow the camera to stay cooler and thus not have the same overheating and shutdown issues.

Ah okay.

But if the video quality drops significantly, doesn't that defeat the whole point of getting the high resolution cams?

Perhaps. I shoot my GoPro and 4K30 H.264 and it performs great. I don't remember off the top of my head how the DR900S looks with H.264 since I was mostly looking at file sizes (that was a while ago so even that I don't remember), but either way, I think it should still be alright. Either way, it's easier to just try it out and see for ourselves and then we'll find out for sure. :)

I have experienced the same thing. I can tell you the camera itself is hot to the touch in my garage. I haven't gotten temperatures, but I pulled my micro sd out of it yesterday and the camera and the micro sd were hot, not warm, but hot to the touch.
Yeah just powered up my 900 in my office. The temperature in my office is 76F. I had the unit on for 20 minutes moving it around from time to time. The unit became very warm. And this indoors at 76F and no sun. I haven't installed on the windshield yet. Will probably do that on Wednesday. It's been in the low 90s to middle 90s. We will see what happens parked in the sun.

I think the quality is equivalent, just that H.265 file sizes are smaller than H.264 == improved compression. Indeed, H.265 takes more CPU work and therefore might exacerbate overheating issues.

Purchased this the end of Sept. didnt know about the overheat issues at the time. Mine was shutting down periodically in the GA weather. For now, I have changed to 264 compression. unfortunately the weather cooled down the last week, so will need more time to see if it alleviates the problem. not exactly the solution I wanted, but for now, its better than the camera shutting down. I do have a 128g card, so not too worried about larger file sizes.

Just got my 900 installed yesterday (it was purchased back in July from Blackvue) on a Tesla model 3 with the B124 battery. Just want to say I appreciate everyone’s comments as I noticed as well I could cook an egg on that thing. And that was sitting in my garage, approximately 80°F outside. Definitely gets hot.

I drove home yesterday from the install shop and I didn’t have any issues. It was a sunny day about 85°F. Of course, only about 20 minutes on the road.

I did notice there was a firmware upgrade to v.1.005 and I upgraded today to the new version. Also, FYI, I’m using the BlackVue 128G SD card that I purchased with the unit.

Will report back if I have any issues with running it on 4K. In other words, my silence means it’s working OK and I don’t need to switch to the 1080P or change to H.264 as recommended in the previous comments.
Thank you again

Good Luck, hope it keeps up for you.

switching to the 264 compression, I no longer got the overheat shutdown, even after spending a week parked in the savannah, ga heat last week. I have since changed it back to the 265 with the cooler weather, also to see if the 1,06 firmware had any effect, which it shouldn't since it was not discussed in the release notes.

LOL, I have the 128GB card, and I want a 512GB card because unlike my DR650GW-2CH, this camera can't do 24 hours on this card.
