A dashcam, dashboard camera, car DVR, driving recorder, or event data recorder (EDR) is an onboard camera that continuously records the view through a vehicle's front windscreen and sometimes rear or other windows. Some dashcams include a camera to record the interior of the car in 360 degrees (inside camera, usually in a ball form) and can automatically send pictures and video (using 4G).
EDRs and some dashcams also record acceleration/deceleration (g-force), speed, steering angle, GPS data, etc.
A wide-angle (130, 170° or more) front camera may be attached to the interior windscreen, to the rear-view mirror (clip on), or to the top of the dashboard, by suction cup or adhesive-tape mount. A rear camera is usually mounted in the rear window or in the registration plate.
Most modern dashcams record in high-definition video (often 1080p, 1296p, 1440p, or higher definition for a front camera and 720p for a back camera) and include f/1.8 aperture and night vision mode.
Dashcams can provide video evidence in the event of a road accident. When parked, dashcams can capture video and picture evidence if vandalism is detected (360° parking monitor) and send it to the owner (usually employing 4G).
