The Guidance for Buying Tachograph
The following points should be also paid attention to when selecting tachograph:
Caching: choosing bigger cache as much as possible is better for smooth video playing and promoted compatibility of memory card.
Night vision: it refers to low illuminating performance of products. An excellent product is not that with LED lamp and red light lamp. The fill light will never be brighter than two headlights however strong it is. It is no able to light the way and will be reflected back when lighting on the front glass, influencing the definition of vision seriously.
Urgent video recording: it is on the basis of the characteristics of the cyclic recording oftachgraph. Even though a video footage is very important, it may unfortunately be deleted automatically because of the later shooting. Thus, a design for urgent video recording will be here. If there is any significant picture recording, what you have to do is to press a button, and the recording will be restored forcefully forever.
Automatic urgent video recording is to use gravity sensor for protecting the video from being covered or deleted automatically when monitoring the violent vibration of cars. This function will perform well when there is car collision.
Shielding measure: copycat product may not take any shielding when designing measure due to low cost. Without strict test, GPS navigation, remote control, radio, tire gauge and ECU will be affected significantly.
