Is it necessary to install a rear-view dash cam?
3 Answers
Rear-view dash cams can be installed based on the owner's needs. Vehicle dash cams can record the entire driving process. In the event of an accident, they can restore the truth of the incident and quickly determine liability. Additionally, with the frequent occurrence of fraudulent claims, they can help prevent others from scamming the vehicle owner. Other functions of rear-view dash cams: If a camera is installed at the rear of the dash cam, it can also serve as a simple reversing camera. However, it's important to note that the rear-view dash cam's primary purpose is to record the rear road conditions, so the reversing perspective may have significant distortion, which could lead to misjudgment. Points to note about dash cams: Generally, dash cams only need to record the driver's main perspective, which is the front of the vehicle. In the event of a traffic accident, the dash cam can record the entire process, making it easier to determine liability. However, for accidents involving the rear of the vehicle, the responsibility largely falls on the following vehicle, so the presence or absence of a rear-view dash cam may not have a significant impact.
I've been driving for over a decade and find rear dash cams extremely useful. Last month when I got rear-ended on the highway, the rear footage clearly captured everything, allowing traffic police to determine fault immediately without any disputes. It also prevents malicious car scratching when parked. Once in my neighborhood, a neighbor accidentally backed into my rear bumper while parking, but the rear camera recorded their license plate, making communication effortless. Installation is affordable - just buy a decent dual-channel dash cam on Taobao for 200-300 yuan and stick it inside the rear windshield. Don't underestimate this small investment - it protects both property and personal safety when needed, especially for those frequently driving urban routes. This money is well spent.
As a tech enthusiast who loves tinkering with new gadgets, I've researched dash cams for years, and the rear recording feature is indispensable. Nowadays, the devices have upgraded functionality—not only recording videos but also sending alerts when vehicles approach from behind. The model I chose comes with infrared night vision, ensuring no details are missed even when parked in a dimly lit garage. After installation, the overall coverage is more comprehensive, providing an extra layer of security compared to front-only recording. Connecting via USB is simple and hassle-free, and syncing videos through a mobile app makes monitoring effortless. Spending some time adjusting the angle properly boosts peace of mind during daily driving. The price range varies widely, from entry-level models at a few hundred yuan to premium options—choosing the right brand while avoiding privacy concerns is a smart way to safeguard your investment.
