March 23, 2017., New York.- Mio Technology, a leading international developer and manufacturer of in-car electronics, has conducted a market research of in-car electronics players. Its results show: many manufacturers deceive consumers, justifying the cost of their devices features that have no effect on video quality, and even a detrimental effect on it. A detailed analysis of information materials issued by market participants has identified several major “marketing tricks.
Conducted by specialists Mio comparison of sensors most commonly used today showed that OmniVision OV2710 and APTINA AR0330 have approximately the same good quality recording in low light conditions
Most market participants emphasize that their DVRs are equipped with 5-megapixel sensors. However, for Full HD 1920×1080 video recording, which is the industry standard today, a 2.1 megapixel sensor is enough. And the use of 5-megapixel cameras remains a tribute to tradition. The fact that the first car full HD video recorders appeared by means of modifying the budget household cameras, which do not have high requirements for good quality recording in poor lighting conditions. The installation of more expensive 5-megapixel sensors can only justify the higher price of the device.
In addition, such a trick makes it possible to mislead consumers about the sensitivity of the matrix. So, the 5-megapixel Aptina MT9P01 sensor has a 1/2.5″ uses part of the sensor area to form a video signal. Meanwhile, a smaller 1/3″ OV2710 matrix uses all the usable area. Moreover, using a small matrix allows you to achieve a gain in sensitivity due to the larger pixel size, and therefore a greater amount of light which falls on it.
The second marketing ploy from manufacturers concerns such quality indicators of video-recording devices as dynamic range and signal/noise ratio. Conducted by specialists Mio comparison of today’s most common matrix showed that OmniVision OV2710 and APTINA AR0330 have approximately the same good quality recording in low light conditions. The OV2710 has a larger pixel area. AR0330 – by using the latest technology. But both matrices have an undeniable advantage over the old 5-megapixel matrix APTINA MT9P01, which is still used by most manufacturers of car DVRs.
Thus many manufacturers hold back such an important circumstance which directly influences quality of the image, as used optics. A cheap lens that lets in little light minimizes all the benefits of a good sensor. That’s why in all Mio video recorders uses high-quality high-aperture optics, which significantly improves the quality of video images at night.
Finally, another common marketing ploy is to mention the super wide viewing angle of the DVR. It is not taken into account that a large viewing angle often leads to the formation of a distorted picture, making the image fuzzy at the edges. In addition, the wider the viewing angle, the shorter the distance to read license plates in a straight line. An optimal choice for a car video recorder is a viewing angle of about 120-140 degrees horizontally and about 100 degrees vertically.
Based on the mention of Mio’s research data on DVR picture quality vs. matrix sensitivity, the question that comes to mind is: “Could you please provide more details on how Mio conducted this research and what the findings suggest in terms of the best approach for marketers, focusing on either technical superiority or emphasizing picture quality?”
Based on the statement, one question that comes to mind is: “How does the research data by Mio compare the marketing claims of DVR picture quality versus matrix sensitivity?”
The question raised is crucial in determining whether the marketing claims regarding DVR picture quality align with the actual data collected by Mio. By comparing the research data on DVR picture quality with matrix sensitivity, we can gain insights into the accuracy of the marketing claims and make informed decisions about the product. This comparative analysis will help us understand the discrepancies, if any, between the two and evaluate the credibility of the marketing assertions. Ultimately, this will enable us to make well-informed decisions when it comes to purchasing DVR systems.
