Hur väljer man höger fram & bak instrumentbräda cam?

Whether you are commuting to work, embarking on a long road trip, or simply running errands around town, the ability to capture both the front and rear views of your vehicle can transform your situation. This dual-lens setup ensures that no incident goes unnoticed and provides you with crucial evidence in case of accidents, disputes, or unexpected circumstances.

In today's article, we will bring you a comprehensive understanding of the front and rear dash cam.

Is it worth getting a front and rear dash cam?

Yes, it is worth getting a front and rear dash cam. Studies show that having a dual-view dash cam can increase your chances of capturing crucial evidence in case of accidents. Around 30% of road incidents involve scenarios from both the front and rear of the vehicle. 

Is the dash cam legal?

Dash cams are usually legal in all states of the United States, and there is currently no national law explicitly prohibiting their installation. However, if the installation is improper, such as interfering with equipment and vision, or removing key safety components such as the rearview mirror of the vehicle for the installation of the dash cam, such modifications will not pass the vehicle annual inspection.

In conclusion, the normal and standardized installation and use of dash cams are legal, reasonable, and widely recognized, which can bring many conveniences and safeguards to car owners. But if the above-mentioned unreasonable behaviors occur during the installation process, it may violate relevant laws, regulations or traffic rules.

How does front & rear dash cam work?  simultaneously?

It obtains power through the vehicle's power interface, and the two cameras at the front and rear simultaneously capture the road scenes. The internal hardware contains two independent camera modules, facing the front and rear of the vehicle respectively. At the software level, the operating system can control simultaneously and send instructions to the two cameras to capture images simultaneously when starting. During image data acquisition, each of the two cameras converts the optical information into electrical signals and transmits them to the central processing unit. The processing unit processes and encodes them separately and allocates different cache areas and data channels for the front and rear views to prevent interference. Finally, the encoded and compressed data are written into the storage device simultaneously in a specific format and sequence to achieve synchronous recording. 

Seven tips to choose a front and rear camera 

Having learned this, do you have the intention to purchase one? Here are some matters needing attention sorted out for friends who may buy a front and rear dash cam.

• Processor performance: The processor is the core part of a dash cam, and its quality directly and crucially affects the stability and video recording effect of the device. You can refer to the relevant chip ranking list to understand its performance. An outstanding processor can guarantee rapid data processing, making the dash cam run smoothly and avoiding problems like lagging and system crashes. For example, some high-end processors can handle multiple video streams simultaneously and work stably even in complex road conditions.
• Lens quality: High-quality lenses have elaborate designs with multiple layers of lenses. This can not only expand the wide-angle range but also significantly improve the imaging quality. You should prioritize multi-coated optical lenses and avoid low-quality ones judged merely by weight. A good lens can capture clear images with vivid and natural colors.

• Image clarity: Generally, a resolution of 1080p or above and 5 million dynamic pixels can meet daily needs. But note that too high a resolution will reduce the recording time on the memory card and may affect the night vision effect.
• Wide-angle size: A larger wide-angle isn't necessarily better. Usually, about 140 degrees can meet the usage requirements. An overly large wide-angle can cause distortion at the edges of the picture and even loss of valid information.
• Night vision effect: It mainly depends on the performance of the image sensor. Both day and night shooting effects need to be considered. An aperture f-value of around 1.6 is suitable.
• Stability: To avoid unstable and shaky pictures and seconds lost due to quality. Dash cams usually have an automatic overwrite function. If the processor capacity is insufficient, seconds might be lost during video connection. It's also necessary to set it accurately according to the local power supply frequency to prevent horizontal stripes.
• Display screen: Dash cams with a screen allow you to view the recorded content directly and the operation is convenient. Those without a screen can obtain data through the mobile phone WiFi hotspot and have the advantages of smaller size and lower heat generation. You can make a choice based on your personal habits and actual needs.
