Single camera or dual camera Dual Camera?

Some driving recorders have two cameras, which have two different designs.

  • Two separate cameras are installed in the front and rear windows: the main purpose is to record the behavior of the car, and there is evidence for being chased. The disadvantage is that it is troublesome to install and route, and it is impossible to record the rear passengers.
  • The camera integrates two cameras, all installed in the front window: the main purpose is to record the rear passengers. Easy to install, just like the dashcam with a single camera. Recording for the rear car is limited, roughly equivalent to the field of view you see through the middle mirror.



Both of the above designs have specific purposes and applicable populations. For most people, the rear-end collision is the responsibility of the rear car. As long as you don't worry about the other party's escape, it may not be necessary to install the recorder on the rear window. Of course, if your area is not so safe, or if you are in a bustling city like NYC, you are often worried that the car will be scraped on the side of the road. The recorders are more reassuring, and there is a 360-degree panoramic dashcam.




Precautions for purchasing a MicroSD card

 

  • Most driving recorders use a MicroSD card to store video. There are three factors to consider when purchasing a memory card.

 

  • Capacity: If recording with 1080P, 32G/64G is recommended, which can record about 5/10 hours. 4G/8G can only record about half an hour/1 hour, which may not be enough. 128G may not be necessary. 1440P HD is recommended for 64G.

 

  • Write speed: Class 10 is enough for 1080/1440P, which means the minimum write speed is 10MB per second; unless you record 4K video, you don't need U-3 (30MB per second) and higher.
