Video storage of an accident (Black Box function)
The system will internally store all film sequences delivered by the camera and overwrite them after some
seconds, if nothing happens. So the system is able to keep a memory recording of the last 12 seconds
before and 6 seconds after an impact such as a car crash or a sudden stop with an acceleration of greater
than 1.5 G (~ 15 m/sec2) should happen. If such a recording has been made, the device will announce an
audio message of "Video has been stored." Using the GPS data, the system stores time, location, speed,
and acceleration information during the accident together with the camera’s video film.
• If you would like to have saved a recorded image (e.g. in case of an accident) on CD, remove the
main unit device and contact ALAN or the distributor where you purchased the product. Authorized
distributors will be able to analyze the image and transfer it to a CD. If You should send the main unit
to the Albrecht / Alan Service, we will send you the device back along with a CD copy of the accident
or image.
• If you do not want to save a video, you can leave it in the memory, because the unit is able to record
up to 3 video sequences. After 3 sequences have been recorded, the next event will automatically
overwrite the first one. So You will have always the last 3 videos available in your memory.
System restrictions and limits for crash recordings: The device records 12 seconds prior to the 1.5G
shock and 6 seconds after it.
It will also record the accident time, location, speed/acceleration information. These information are obtained
from the GPS data, so please consider that the black box functions are not available in absence of GPS
signals (for example in tunnels). After a 1.5G shock, power must be maintained for at least 20 seconds to
record the image correctly. If the car’s power supply should be interrupted during a heavy crash, the unit may
not save properly.
It is possible to set off the 1.5G sensor without an accident. (Road condition or sudden stops may set off the
1.5G sensor). In the event that the F-A-S 100 system records a video when there was not an accident,
please press the button that will erase the video.
