Recording
RING BUFFER CONCEPT
Before starting to record, it is important to understand the concept of how the images
are stored in the camera. Considering that the camera needs to capture an immense
amount of data in a very short time, the quantity of very fast memory is limited, hence it
is paramount to manage that memory properly to mitigate the loss of frames after the
camera has been set to record.
In order to capture all these images, the Chronos cameras will record to what is called a
Ring Buffer in the internal high-speed RAM. The ring buffer is a data structure that
holds frames of recorded video. Once it’s full, the oldest frames are overwritten as new
frames are captured. This allows the camera to record for unlimited periods, but only the
most recent frames are kept.
The length of the buffer depends on the Record settings.
Reducing the frame rate below maximum will increase the
record time proportionally.
For example, if the maximum frame rate for your resolution is 3000fps, setting the rate
to 1000fps will result in 3x the record time available at maximum frame rate.
