Front and Back Dash Cam, 4 Inch Touch Screen

4" front and back dash cam has a waterproof rear camera. It can easily realize safety reversing. There are 4 display modes for real-time images: only show the front image, only show the rear image, a small window for rear image in the edge of front image, and a small window for front image in the edge of rear image.

Features:

1. G-sensor
   Turn on collision sensing function. After an emergency brake or collision, car dash cam will automatically lock the current video without being deleted/ overwritten, and save it as the accident evidence.
2. Reverse image
   Car-level rear camera supports reverse image, and automatically switches to this mode when the car is reversing.
3. 24-hour parking monitoring
   DVR dash cam can be equipped with a step-down cable and realize 24-hour parking monitoring. It can guard all-weather real-time monitoring of theft, scratching, and recording accidents.
4. Replay viewing
   Use the car dash cam to view the playback video anytime, anywhere, and observe the recorded content to quickly resolve driving disputes.
5. Loop recording
   Whenever the memory card is full, the dash cam will automatically loop cover the previously unlocked videos, which will save storage space and save the most recent videos at all times.
6. Motion detection
   Intelligent detect movement and recognize moving objects.
7. Blank screen recording
   The video can be recorded even when the screen is off, which can save power consumption and improve driving safety.
8. Full-automatic working
   Dash cam will automatically start to record when the car is ignited, without manual operation. After stopping and powering off vehicle, the dash camera will automatically shut down after a 10-second delay to protect the car battery. (Except when the cigarette lighter is continuously powered after the car is off, or the dash cam is connected to an additional battery.)
9. Automatic WDR+HDR dynamic processing
   Perform DSP intelligent arithmetic processing on the bright and dark parts of the image to improve image quality and detail performance.
10. High-brightness LED light
    When the night light is insufficient, especially in the parking monitoring mode, the fill light is automatically turned on to avoid too dark light and unclear pictures.

Tips: What is the G-sensor of the car dash cam?
There is a G-sensor function of the dash cam. Its main effect is to record and lock the video in real time after the car collides to prevent it from being overwritten.
Gravity sensing is also known as crash recording. When the CPU of the dash cam reads that the value of the gravity sensor exceeds the set value, it will consider a crash occurred, and the current video will be protected against deletion, thus realizing automatic storage function. Generally, the car dash cam gives three setting options of high, middle and low. When the car often accelerating or decelerating and driving on the rugged road, as long as the dash cam is set to high or medium state, the video will basically be saved as a read-only state, that is, all the videos are saved and can't be overwritten. So it is recommended to turn off this function and save the video manually when a collision occurs. Most dash cams are also equipped with a one-key emergency storage function.
If you like to turn it on, it's best to set it to low, and then format the memory card regularly (according to the size of the card and the driving distance per day), so as not to save too many videos. As a result, the memory available for loop recording is reduced. When the memory card cannot continue to record, or there is an entire segment of some videos in the memory card missed, please check the status of G-sensor function.
