Why is there a Didihu in the car?

Intelligent driving system, this is the navigation function. The following is a relevant introduction about in-car navigation: 1. Concept: An in-car navigator is a driving assistance device that can help users accurately locate their current position, calculate the journey based on a set destination, and guide users to the destination through map display and voice prompts. 2. Operating principle: GPS consists of three main parts: space satellites, ground monitoring, and user receivers. In space, 24 satellites form a distribution network, distributed in 6 quasi-synchronous orbits around the Earth, each orbit 20,000 kilometers above the ground with an inclination angle of 55°, and each orbit has 4 satellites. GPS satellites orbit the Earth every 12 hours, enabling any location on Earth to simultaneously receive signals from 7 to 9 satellites.
I installed a Didihu in my car mainly for safety reasons. As a family car owner, I often take my kids to and from school or go on road trips. Having a dash cam in the car allows me to monitor the road conditions and the interior situation at any time. It's a type of in-car recording device, with the front camera recording the driving process and the rear camera monitoring the trunk. When parked, it automatically activates the anti-theft mode, alerting and sending messages to my phone if there's any movement. Last time when I parked in the neighborhood, my car got a small scratch, but thanks to the recorded video, I found the neighbor responsible and got compensated. It also connects to an app for remote viewing of the location and video clips, and it can record beautiful scenery as a souvenir during trips. It has an independent power supply, so it doesn't drain the car battery, and installation is simple—just stick it to the windshield with 3M tape. Adding such a device doesn't cost much, but it gives me more peace of mind while driving and ensures evidence in case of accidents. In short, Didihu is a great helper for modern car owners.
