Hard enough quality, functional stable, clear pictures can be said that these three "tachograph what makes a good" best annotations than Fangke Han logger can say is recognized as high quality, functional stability, the role of explicit pictures recorder, which features a stable of high quality can also be said to be a reflection of, and the role of this camera recorder night vision must be clear. ? In our actual purchases are difficult to distinguish, and view, then we should be suitable for the performance of the recorder is stable and can be crazy buttons, the machine is sensitive reaction test, whether there will be situations card machine and crashes, which is the simplest kind of way. What is driving record instrument: mounted on the front windshield of the car, shot the driver a ride for DV machines, dynamic shooting and video traffic accident liability in favor of the differences and deal in foreign regions are more prevalent. This product was the birthplace of Korea, commonly known as car black box, in addition to shooting dynamic and video, but also with G-SENSOR and GPS track records, but to the country, a lot less function, it can only be called driving record instrument, more suitable conditions. Role, the role of the recorder day are similar, whether it is high-definition still puqing, due to the camera chip in the day light satisfactory situation, the software processing, the role is very good; but the night came to the fore differences, and this that is why so many logger with infrared lights up! But the role of infrared light is very small, small infrared light power did not reach the required only as a selling point; many so-called high-definition recorder, often false; a standard definition is very simple: HDMI interface, is You can not have high-definition interface for logger discrimination is not HD; another is tight format, many with MJPEG, this treatment is not very good quality, professional monitoring is the H.264 compression format; open driving record Miriam motion detection function, the machine boots up, the recording standby state, when the useful area inside the front of the camera to monitor a moving object through the period, the machine will automatically recording, perhaps out of a moving object suspend activities useful area of ??the machine take the initiative to suspend the video! Of course, motion detection light intensity might be affected and car glass viewpoint and film varieties, and even not normally use. Sensitivity to provide the basis for a traffic accident, the car can travel the whole process of recording video pictures and sound, the internal shock sensor can be set, and when the external impact force greater than the set value, resulting in the impact of the field data will be recorded . Eradicate deceive prudent action. 4 Reasons to Choose Section culvert 1:10 in brand precipitation, ultra high-definition tachograph first 10 years of export brands, products exported to Europe, famous exhibition (Germany IFA, US CES Taiwan Computex, Hong Kong CSF) Exhibitors 50 professional R & D team, down to the hardware group, the software group, test group and other eight functional teams within the company management: Kingdee ERP management system, accessible OA paperless office system 2: Product improve the internal quality inspection and testing to ensure product excellence through six security detection test (PCBA function testing → Chassis → high temperature detection function detects the whole 24 hours aging test → → → packaged whole appearance detection test) have passed the high and low temperature testing, vibration testing, eight professional and reliable Test Experiment 3: Focus on quality expertise in ultra-high definition detail tachograph first brand imported by the United States Ambarella Ambarella chip ultra-wide angle, loop recording, super night vision passed ISO9001 quality system certification, with the invention, utility model, appearance, etc. 30 patented 4: improve the quality of service team to provide you with a strong service guarantee a response within 48 hours of delivery, SF worry-free service nationwide free shipping, less than a year that is artificial damage retired functional replacement for new host families Han is easy to think of Shenzhen Science and Technology Co., Ltd's own high-end brands.
