What are the functions of a dash cam?

Automobile driving recorders have functions such as identity recognition, recording vehicle driving time, speed, mileage, overtime driving (fatigue driving) alarm and recording. They also include management software, providing a good human-machine interface to achieve vehicle information input, modification, query statistics, and report printing functions. When using a dash cam, secure the recorder to the car's rearview mirror with a clip, place a power supply device in the glove box, and connect it to the central control cigarette lighter. At this point, the dash cam, portable navigation, and radar detector can all be powered by the power supply device. Finally, tuck any excess wiring behind the glove box. Generally, dash cams do not have built-in memory and rely on memory card expansion or mobile digital hard drives. For SD card expansion, capacities vary from 2G, 4G, 8G, 16G, to 32G. For mobile digital hard drives, capacities can be 250G, 500G, 1000G, etc., meeting users' greater video storage needs.
Having driven for over a decade, my dash cam has become a loyal companion. Its primary function is to continuously record videos of the front and rear views while driving, providing solid evidence in case of accidents or fraudulent claims to determine who's at fault. It also automatically activates parking surveillance, detecting movement and recording when parked. Once, after coming out of a supermarket, I found my car scratched, and the surveillance footage helped me identify the other party. The GPS function records routes and speed, assisting in reviewing driving conditions. Loop recording ensures uninterrupted video without worrying about the memory card filling up. An added benefit is the peace of mind it brings, reducing insurance disputes. I recommend installing one regardless of the car model—it's simple to plug into the cigarette lighter to start, and the night vision function provides clear footage even in the dark. Using it makes driving more confident and reassuring.
As a tech enthusiast, I find dash cam features incredibly cool. The core function is high-definition video recording, capturing clear footage both day and night, with infrared technology providing fill light for night vision. Wi-Fi connectivity allows direct control via smartphone, making it easy to download and share recordings. When parked, built-in sensors detect movement or collisions, automatically triggering video saving to prevent loss of evidence. GPS tracks routes and speed, and some models even integrate ADAS collision warnings. The motion detection is highly sensitive, acting like a little guardian for the car. I also enjoy experimenting with different brands, comparing 1080P and 4K effects. External power ensures reliable battery life, and the combination of features is both practical and innovative.
