Abstract
A recording apparatus and process for conserving space on a recording medium of a security system includes the steps of detecting a motion amount from the image picked up by a camera, while recording the image, comparing the detected motion amount to a predetermined threshold, and increasing a counted value when the motion amount is equal to or lower than the predetermined threshold, and resetting the counted value when the motion amount is higher than the predetermined threshold, and comparing the counted value to a reset value, and when the former is higher the latter, rewinding until the counted value becomes zero, and then return to the step of detecting a motion amount. Therefore, motion of a recorded image signal is detected and compared. A recorded part is found, in which no motion occurs for a predetermined period of time. Recording is again performed, to overwrite this part where no motion occurred. This increases the available recording time, and economizes use of space of the recording medium.
