A dashcam, dashboard camera, car DVR, driving recorder or event data recorder (EDR) is an onboard camera that mainly continuously records the view through a vehicle's front windscreen and sometimes rear or other windows. Some dashcams include a hidden camera to record the interior of the car in 360 degrees and can automatically send pictures and video. Driving recorders and EDRs also record acceleration/deceleration (g-force), speed, steering angle, GPS data, etc.
One wide-angle (130, 170° or more) front camera may be attached to the interior windscreen, to the windshield mirror or to the top of the dashboard, by suction cup or adhesive-tape mount. The backup camera is usually mounted in the rear window or in the registration plate.
Dashcams record in high-definition video (today at least 1080p, 1296p, 1440p or higher definition for front camera and 720p for back camera) and include f/1.8 aperture and night vision mode.
Dashcams can provide video evidence in the event of a road accident. Rear cameras can help with parking, and, 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).
Traffic Collision
A traffic collision, also called a motor vehicle collision (MVC) among other terms, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, death, and property damage.
A number of factors contribute to the risk of collision, including vehicle design, speed of operation, road design, road environment, and driver skill, impairment due to alcohol or drugs, and behavior, notably speeding and street racing. Worldwide, motor vehicle collisions lead to death and disability as well as financial costs to both society and the individuals involved.
In 2013, 54 million people sustained injuries from traffic collisions. This resulted in 1.4 million deaths in 2013, up from 1.1 million deaths in 1990. About 68,000 of these occurred in children less than five years old. Almost all high-income countries have decreasing death rates, while the majority of low-income countries have increasing death rates due to traffic collisions. Middle-income countries have the highest rate with 20 deaths per 100,000 inhabitants, 80% of all road fatalities by only 52% of all vehicles. While the death rate in Africa is the highest (24.1 per 100,000 inhabitants), the lowest rate is to be found in Europe (10.3 per 100,000 inhabitants).
