![]() ![]() Most importantly, supercapacitors can withstand the harshest temperatures without risk of damage even after years of daily use. Those components can hold a charge for a short period of time, for example to allow the dash cam to safely end a recording to avoid file errors when shutting down–accidentally or not. That’s why all BlackVue dash cams have always come equipped with supercapacitors instead. Both cold and hot temperatures will do a number on lithium-ion batteries, with heat in particular potentially causing swelling or even fires. Unfortunately, that comes at the expense of temperature resistance. Lithium-ion batteries are perfect for their high energy density. While some cheaper models advertise lithium-ion batteries as a perk, we believe that even an entry-level dash cam should not compromise on safety. Heat and cold resistance Supercapacitors vs lithium-ion batteries Moreover, a good dash cam should be able to record reliably over hours in hot and cold temperatures. Check this in-depth video by YouTuber Vortex Radar for a better understanding of this topic. This is why a lot of premium dash cams often perform even better than premium action cameras in low-light situations. For the best results, the engineers need to spend time not only coding but also testing in real-life situations, gather their findings and further improve their algorithms.Ī good dash cam will generally be tuned to produce useful footage in a wide range of lighting situations, including at night. ![]() They do so by applying noise reduction, color correction and a multitude of other tweaks. ISP tuning is the process by which engineers take the raw image output by the sensor and convert it into the final image produced by the camera. That’s why image signal processor (ISP) tuning is becoming more and more important to extract the best results out of any chip and sensor combination. However, as the available light goes down or the action speeds up, blurriness will always become an issue. Even the cheapest cameras nowadays can capture decent footage in bright daylight. The truth is, out of the box, even the best CMOS sensors from the most reputable manufacturers can produce subpar results if they are not tuned properly. However, one of the common misconceptions about video quality is that if you are using a good lens, sensor and processor, you will mechanically end up with good image quality. Oh, and of course, these components need to be somewhat affordable enough for a consumer-level product. Then the processor needs to be efficient and generate as little heat as possible as well. The lens should have a wide-enough view angle to cover the action without introducing too much distortion or blur. When it comes to image quality, this means choosing a sensor that will have high enough resolution but also good low-light sensitivity, all in a small form factor and without generating too much heat. It goes without saying that selecting the best components for the job is a crucial part of building a quality dash cam. Image quality (hardware + ISP tuning) Quality hardware components: lens, sensor, processor. why alternatives like action cameras may not be ideal to use as a dash cam.what goes into the development and manufacturing of a premium dash cam, such as a BlackVue.Or perhaps you are thinking about using an action camera or an old phone instead of a dedicated dash cam? In this article, we will cover: BlackVue is compatible with every type of vehicle and can be used by individual users or entire fleet of vehicles.įor more info about the collaboration, Mapillary’s camera grant program and pricing head over to Mapillary’s website.One of the most common comments we get here at BlackVue is “why does this dash cam cost this much? I found one on Amazon for $30!”. To optimize BlackVue for mapping purposes, Mapillary teamed up with the BlackVue manufacturer Pittasoft and developed a special custom firmware designed for capturing imagery that helps improve maps from every hour of the drive. So far, anyone could contribute with such tools as their smartphones or action cams, but now street-level image collection got even simpler and more convenient thanks to Mapillary customized BlackVue dashcams! In other words, Mapillary brings together a global network of contributors who want to make the world accessible to everyone by visualizing the world and building better maps. Mapillary is the street-level imagery platform that uses computer vision to fix the world’s maps. We are happy to introduce a new BlackVue collaboration – Mapillary customized DR900S Series dashcams! ![]()
