Cheyou's loyal companion, the driving recorder, is an instrument that records information such as images and sounds while the vehicle is in motion.
With the occurrence of various moral declines in recent years and the chaotic traffic in the city, more and more riders have begun to understand that only retaining evidence can better protect their legitimate rights in the road. As a monitoring tool, the driving recorder has been selling well in China in the past two years. Let's take a look:
The driving recorder is mainly composed of three major components:
1. The main control chip CPU, the main control chip is equivalent to the computer's CPU, it is responsible for image data acquisition and data compression, is the core component of the recorder. At present, there are mainly Ambarella, Novatek, Zoran, Sunplus, STK, SQ, and Zhizhi.
According to the resolution of the video, it can be roughly divided into three series: VGA (640x480), 720P (1280x720), and 1080P (1920x1080).
VGA (640x480) is the earliest product specification. The current solutions are: Taixin (STK), SQ, Sunplus (Sunplus), which are generally used in low-end recorder solutions. Taixin (STK), SQ, Sunplus (Sunplus) can also interpolate VGA (640x480) to 1280x720 by software, but it is not real hardware decoding. Compared with VGA (640x480), the actual effect is not improved, but instead recording Take up more memory space;
720P is currently the most cost-effective specification, the solution providers are: Quanzhi, Novatek, Zoran, hardware decoding to achieve 720P effect, generally used in high-end solutions;
The 1080P products are available from Ambarella, Novatek's NT96650 and Quanzhi's F20, but at a higher cost.
From this, the pros and cons of the main control chip and the cost sequence are: Ambarella, Novatek, Allwinner, Zoran, STK, and SQ , Sunplus (Sunplus).
2. Image sensor Image sensor is also an important component of the driving recorder. At present, most of the driving recorders are OmniVision, Micron and sensors of companies such as ApTIna separated from Micron, mainly 300,000, 1 million, 5 million. 8,800, or even 12 million pixels.
3. Lens, the lens used in the current driving recorder, the fixed-focus lens usually uses the lens of Taiwan manufacturers, such as Taiwan Dali, matt plastic or glass fixed-focus lens.
The main chip manufacturers of driving recorders mainly include:
First, Ambarella: American company, advanced image processing and image compression algorithms, can be said to be the leader of this industry. The Aba series chips, which are used in high-end products, have good picture quality, stable performance but very high price. The core technology is not disclosed. Without authorization, the original technical support is not available.

Second, Zoran (Zoran): Also a company in the United States, mainly engaged in the design and development of digital audio and video integrated circuits and market sales, with the representative of the Taiwan brand Garmin driving recorder. Recorder market investment is relatively small, and market share is gradually decreasing.
With the ZORAN Zoran program:
CANSONIC - MDV-3000
Fly to the news - FDV-1080 WOW
Garmin - GDR35 (C14P)
Third, Taiwan Unicom (Novatek) : Taiwan's second largest IC design company, strong strength, top technology in general, but mature technology is doing very well, the price is relatively low, the product cost is very high. Especially after the launch of the NT96650 in 2013, 1080P also has its place, and with the WER and the magnesium imager AR0330, the performance is amazing, and even the picture quality clearly outperforms the Anba program. The advantage in price will prompt the company. Competitiveness has increased dramatically.

Fourth, SQ / Lingyang / Taixin : Taiwan company value is low, like a cataract during the day, like a chameleon at night. Generally used in insurance companies to purchase gifts.
Taixin master chip has:

With the strong solution:
FLYTEC - FS-101
Five, all wisdom : high-end, price advantage, performance is also excellent. The image processing capability is relatively high (multi-lens support), but the power consumption is slightly larger. It is mainly in the dual-lens and multi-lens recorder market, the real front video 720P, rear video VGA. The dual camera is not the Zallan all-in-one chip, the Zoran brand is used, the smart chip is cheap but the hardware is only 1.3 million pixels.
With the all-intelligence scheme:
FLYTEC - FS-101
