Discrete 4K Dash Cam with external DVR

Wouldnt it be better to make a dashcam with an external DVR? That way you would 1, Reduce the camera footprint for a more discrete approach. 2, More easily accessible SD card and DVR + other features. 3, The biggest problem of all, The main electronics will be out of direct sunlight resulting in little to no heat soak. 

 

Having all the electronics in one place especially in such a small camera causes a large amount of heat it's self, throw in direct sunlight and you have a very expensive dummy camera with rapidly degrading electronics and many failed SD cards.

 

I Personaly think this will be a better option and with the possibility of adding more cameras.

 

Cheers,

Mike.

    Let's just start small by getting the current cameras to work properly.^^

    There is too much going on in such little space. There is the voltage regulator ( Not sure if it is linear or buck), The SD card, Camera sensor, Microcontroller, Wifi Chip and other electronics all giving off a lot of heat. When running high-quality recordings this will cause a lot of heat and the only way to combat this is to drop the quality. When you spend £500 on a 4K dash cam you want it to run at its best for long periods of time without interruption or quality loss and not have to update the firmware with a lower bitrate just to lower the temps.

     

    Blackvue have had long enough now to sort the problem, and I feel the only way to sort the heat issue is to separate the components and have the DVR away from direct sunlight.

    Not really. Introducing yet another source of problems isn't really the best method of solving the other ones. I do agree, it's pretty crammed in there, but shifting parts of it t another location adds more and thicker cables. The current power/2nd camera cables are already too much for just squeezing them under most headliners.

    The biggest problem (for me) is that the focus shifts with temperature and the software being total trash. The camera does get well over 90°C warm before it shuts down. While doing so, the video quality is as bad as when it's cold. I really can see much of a difference there. It's also not something you could avoid. The major heat source is the video processing chip, which can't be placed at any distance from the camera module. The power supply uses a simple step-down converter with 70%+ efficiency.

    I'd like to see a open source firmware. That would be great. The hardware is already acceptable, if you ignore the lense system and the photo sensor xD
