A dashcam or dashboard camera is an onboard camera that continuously records the view through a vehicle's windscreen. It may be attached to the interior windscreen or to the top of the dashboard, by suction cup or adhesive-tape mount. Dashcams may provide video evidence in the event of an accident. Various types of dashcam are available on the market, ranging from basic video cameras to ones which also record parameters such as date/time, speed, G-forces and location. Most dashcams are manufactured in Asian countries such as China and Taiwan. Due to the lack of governmental regulation in those countries, there is usually very little quality control in most dashcams. Dashcams are widespread in Russia as a guard against police corruption and insurance fraud, where they provide additional evidence. They have been called "ubiquitous" and "an on-line obsession", and are so prevalent that dashcam footage was the most common footage of the 2013 Chelyabinsk meteor, which was documented from a dozen angles. Thousands of videos showing automobile and aircraft crashes, close calls, and attempts at insurance fraud have been uploaded to social interactive and sharing websites such as YouTube, Facebook, Twitter and other websites. Dashcams are gaining in popularity in many parts of Asia, Europe (particularly in France), Australia and the US. They are forbidden by law in Austria, where they carry heavy fines. In Switzerland, their use is strongly discouraged in public space as they may contravene data protection principles. 〔(【引用サイトリンク】title=Guidelines on video surveillance in vehicles (Dashcams) )〕 In Germany, while small cameras for personal use in vehicles are allowed, posting footage from them on social-media sites is considered a violation of privacy and thus forbidden. Dashcam footage is only in exceptional cases admissible as evidence in a German court. In Australia and Poland, recording on public roadways is allowed as long as the recording does not infringe upon one's personal privacy in a way that may be deemed inappropriate in a court of law. ==Police use== Police departments use dashcams in police vehicles to gather evidence during traffic stops and car chases.〔(【引用サイトリンク】title=Cross-Examining Film )〕 Some dash cam systems can be automatically activated when a police car's emergency lights or siren are turned on.〔(【引用サイトリンク】title=Local police support dash cam policies, protecting citizens and officers )〕〔(【引用サイトリンク】title=LAPD officers tampered with in-car recording equipment, records show )〕〔(【引用サイトリンク】title=Court orders state police to hand over cruiser dash cam video of crash scene )〕 Freedom of information laws mean that the footage can be released under some circumstances,〔(【引用サイトリンク】title=Court rulings bolster public access to police videos )〕 and this can be an important tool in reporting on police actions.〔(【引用サイトリンク】title=How a little-known, Uber-driving freelancer brought the lawsuit that forced Chicago to release a police shooting video )〕 TV shows like ''World's Wildest Police Videos'' have frequently featured car chase videos shot from dashcams. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dashcam」の詳細全文を読む スポンサード リンク
