After getting involved in the tachograph industry, in 2012, the intelligent functions have been applied to the dash cam, and in less than a year, it has successively launched a dash cam with lane departure reminder, front car start reminder and other functions. For the most basic recording function of the dash cam, many of the products of Pai Pao Dog have performed well, and a few products are equipped with advanced chips and image sensors in the industry.
 
As a veteran manufacturer of tachographs, in recent years, the market share of Pai Pao Dog has been declining, not only because of its positioning, but also because of 360, Xiaomi and other companies to enter the tachograph industry, aside from the brand bonus, in terms of products alone, Pao Pao Dog's various tachograph products are the most cost-effective choice for consumers.
 
There are many product lines under Papaogou, with more than 10 series such as GoSafe, C, D, F, H, N, etc. It should be noted that there is a big difference in product strength between different series, and there is also a big difference in the performance between different products in the same series. GoSafe series is the most recommended series of dogs, the series generally uses Novatek chip Sony image sensor scheme, the difference between different models of dash cams lies in the difference between the main control chip model and the image sensor model.
 
In the field of night vision performance,GoSafe 560WIFI is undoubtedly the most worthy series,Its Novatek high-end NT96663 chip Sony IMX291 starry sky night vision chip,And using the mainstream high-end machine on the market6G 1IR lens,Up to support1440P video resolution,The picture quality performance is very good,The current price is between 549-699 yuan。 The same hardware configuration is also used N291 series N291, the difference between the two is that N291 aperture is larger, F-value is 1.33, and 560WIFI aperture F-value is 1.6, the smaller the F-value of the dashcam (other parameters remain the same), the more conducive to night scene shooting, the better the night vision effect, but the aperture F-value is smaller, the depth of field will also become shorter, and it is not easy to see the license plate slightly farther away.
 
In terms of the choice of main control chips, there are three main types of Novatek NT96663, Novatek 96658 and Novatek custom chips, of which NT96663 is the highest-end chip, followed by Novatek 96658 and custom chips. Novatek 96663 and 96658 chips are equipped with a new generation of WiFi module, which can establish a LAN connection with the mobile phone to achieve zero-traffic video transmission.
 
In the choice of image sensors, there are also Sony IMX291, IMX323 and Haowei Technology OV4689, etc., Haowei OV4689 Although it has 4 million pixels, it is not a real low-illumination chip, its pixel particles are only 2μm, and the performance in low light (night vision) is insufficient.
 
On the other hand, Sony's IMX291 has only 2 million pixels, but it is equipped with Sony's exclusive STARVIS technology, and its night vision ability is still very impressive. Although the Sony IMX323, which is also 2 million pixels, is not equipped with STARVIS technology, its pixel particles reach 2.8μm, and the effect of receiving photons is better, and the night vision ability is still better than that of OV4689. Users can use it as a reference when purchasing Papa Dog products.
