Introduction to Driving Recorder

The driving recorder is a device that records images and sounds related to vehicle driving. After installing the driving recorder, it can record the video images and sounds of the entire process of car driving, which can provide evidence for traffic accidents. People who like self-driving travel can also use it to record the journey of overcoming difficult obstacles. When driving, record videos and record time, speed, and location in the video, which is equivalent to a "black box". It can also be used as a DV to shoot life fun at home, or used as home surveillance. Normally, it can also do parking monitoring, the installation of the driving recorder, video data cannot be trimmed, if trimmed, it cannot provide help after the liability accident occurs. It is also to prevent the unavoidable touching porcelain behavior in society.

Function of Driving Recorder

1. Safeguard the lawful rights and interests of drivers, against those who frequently cross highways on foot, bicycles, or motorcycles. In case of scraping, you may be blackmailed. With the driving recorder, the driver can provide effective evidence for himself.

2. Replay the surveillance video recording, and the responsibility of the accident is clear at a glance. Traffic police handle accidents quickly and accurately; they can quickly evacuate the scene to restore traffic and retain effective evidence at the time of the incident, creating a safe and unimpeded traffic environment.

3. If a driving recorder is installed in every car, the offending vehicle will be captured by other vehicles' driving recorders. Traffic hit-and-run cases will be greatly reduced.

4. When courts hear road traffic accident cases, sentencing and compensation will be more accurate and justified, and it will also provide evidence for insurance companies to indemnify.

5. Encountering professional touch porcelain and roadside robberies, the driving recorder can provide decisive evidence to crack the case: the accident scene and the physical characteristics of the perpetrator, etc.

Classification of Driving Recorder

The driving recorder is mainly divided into two major categories: portable driving recorders and post-fitting car machine integrated DVD driving recorders. Among them, portable driving recorders are divided into rearview mirror driving recorders and data driving recorders. This type of recorder has advantages such as good concealment, easy installation, replacement, low cost, and easy use; while the post-fitting car machine integrated DVD driving recorder is generally dedicated to the vehicle and is divided into pre-installation and post-installation The installation cost of this type of recorder is higher, the modification difficulty is larger, but it can maintain the beauty of the car interior after installation. In addition, some luxury car models have been installed with driving recorders when they leave the factory.

Tips for Choosing a Driving Recorder

When choosing, you need to analyze product parameters, including shooting angle, video resolution, compression format, cache, whether the video can be manually turned off, emergency video recording, and it does not interfere with other car electronic products.

Shooting angle: The shooting angle of the driving recorder is mostly about 100 degrees, and this angle can basically ensure that the lanes on both sides of the vehicle are taken in. A larger camera angle helps to fully record the surrounding vehicle's situation. But remember, the lens angle should not be too exaggerated, so as not to distort the picture taken.

Video resolution: Generally speaking, when the video resolution is 1280*720, it can basically ensure that the license plate of the car in front can be clearly seen, and the license plate of the side lane is relatively blurred. In addition, the sensitivity of the CMOS chip of the recorder and the quality of the glass of the external lens. It directly affects its shooting effect at night.

Compression format: Driving recorders mostly use H.264 compression format. Without a good compression method, it not only means more storage space, but also higher requirements for the speed of the storage card. Otherwise, it is easy to drop frames, affecting the compatibility of the storage card driving recorder. For cars, choosing a reasonable recording interval and capacity to assist in bringing about timely evidence in case of an accident is generally advisable to choose one minute as the interval time.

Cache: Choose as large a cache as possible, which can bring smoother video and better storage card compatibility.

Night vision effect: The night vision effect mentioned here refers to the low-light performance of the product. Outstanding products are not ones with LED lights and infrared lights. No matter how strong the supplement light is, it's no brighter than two car lights and can't be photographed on the road. Moreover, the reflection on the front glass severely affects the clarity of the line of sight recording.

Emergency recording: Based on the cyclic recording feature of the driving recorder mentioned above, if there is an important video, but future videos still need to be shot, then the important video recorded earlier will be automatically deleted. At this time, the design of emergency recording appears. If there is an important image, just manually press a key, and it will forcefully save this video so that it will not be automatically deleted when the card is full. Automatic emergency recording uses a gravity sensor. When a violent vibration is monitored in the car, it will automatically protect this video from being automatically overwritten and deleted. This function will be very useful when the vehicle collides.

Shielding measures: Shanzhai products does not adopt any shielding measure to reduce cost during design, without rigorous testing, it will interfere with GPS navigation, remote control, radio, tire pressure monitor and car computer, etc. The influence is huge when something happens.

In addition to the above points that need to be noticed when choosing a purchase, try to choose a product with a larger cache. A larger cache can bring users smoother video and better storage card compatibility. Driving automatic recording, turning off the flame automatically, and covering automatically are basic functions of the driving recorder. When buying, remember to ask clearly.
