Event Recording: Fill & Download for Free

A2A thanks CyrusAre we still debating this?Europe starts in Greece.Geographically.Culturally.Scientifically.Philosophically.Historically (first historians and events recorded were Greek).Politically (Democracy first appeared here and Greece is a EU & Eurozone member).Religiously (Christianity was first adopted in the Eastern Roman/Byzantine Empire).Even linguistically since Ευρώπη is a Greek word.So it would be prudent to assume that people who live in Greece are European.

In 3100 BCE, two officials of a temple in Jemdet Nasr (then part of Sumeria, now part of Iraq) received a load of barley. They have been receiving and distributing barley for four years already. In six instalments they received some 160 barigs (one barig equals to 300 litres approximately) of barley.That is the oldest event recorded in history.The event is documented in the Jemdet Nasr tablets, the earliest written script found and read.Here’s a link if want to read more on the tablets: Revisiting Jemdet Nasr Texts.

The audio on police body cams and many dash cam systems begins recording as soon as the “record” button is pressed. The reason you often don’t hear any audio for the first 30 seconds is because of “pre-event recording.”With modern (the last ten years or so) car and body cam recording equipment, the camera is recording whenever it’s powered on, whether it’s in “record” mode or not. The video is sent to a solid-state buffer that holds the last 30 seconds (the interval is variable with many systems, but 30 seconds is standard) of video. This is constantly being updated.When the operator pushes the “record” button, the contents of the buffer are appended to the front of the recording. This 30-second segment has no audio, for privacy protection. Most cops don’t want to have a device that records everything they say throughout the entire shift.When you see a police bodycam or dashcam video online, the first 30 seconds is often silent (and largely uneventful) because you’re looking at the contents of that pre-recording buffer. The sound comes on once the officer pushes the “record” switch.The pre-event feature was created to overcome a shortcoming with dash cam video. While the officer was on patrol, some noteworthy event (someone running a red light, the brandishing of a gun, an explosion, whatever) would take place within view of the camera. However, if the recorder wasn’t turned on, the event wouldn’t have been recorded. The officer could capture everything that happened afterward, but the incident that created the need for the recording was lost.Early systems were not much more than VCRs connected to cameras mounted on the dash, and recording onto two-hour VHS cassettes. That technology didn’t provide for pre-event recording. When the systems started to become 100% digital, the pre-event recording feature was possible.
