Shock sensor detects sudden acceleration, breaking or impact, and locks the video file. This automatically protects most important video clips from overwriting when memory card runs out of free space. Also it triggers recording in parking monitoring mode.
If shock sensor detects an impact, it turns the camera on and record short video clip. Then camera turns off again to save battery. This helps if your parked car was hit.
If enabled, camera only records when it sees something moving. If a picture does not change, then nothing is recorded. This is helpful to conserve the space on the memory card then your car is stationary.
This is a digital interface to connect your camera to modern flatscreen TV to see your video in razor sharp Full HD.
This is analog interface to connect your camera to older TVs and VCRs.
If turned on, when your memory card runs out of space, oldest files are being overwritten by newer ones so the recording never stops.
With GPS receiver, the camera can record current speed and coordinates. These data not only imprinted on the video, but also you can see your track on the map with special software.
Built-in processor can analyze video feed and it can warn the driver as needed. For example, if you forgot to turn on your headlights, or you following other car too close, it will warn you. If you stopped at intersection, and a car in front you moved, but you did not - it can gently let you know.
With optional backup camera, you can clearly see what's behind your car when you are backing up. Backup camera usually mounted right over rear bumper so it gives you much better view than through rear view mirrors or rear window.
If you happen to do not have a photo camera with you, you can take a photos with your dash cam. For example, if you had an accident or need to capture something important. However, you don't need to take photos when your camera shoots a video — the video is good enough to make clear and sharp stills in Full HD resolution.
