Video recording apparatus and controlling method thereof

A video recording apparatus, comprising:

• a camera configured to perform a video recording function of an outside of a vehicle;
• a motion detection controller configured to:
• obtain sensing data in a digital format at specific intervals based on a reception signal of radar;
• determine a detected distance of an external object based on the obtained sensing data;
• determine target data when the detected distance is less than a threshold distance;
• and
• output an activation signal when a number of the target data is greater than or equal to a second threshold value;
• and
• a main controller configured to activate the camera based on receiving the control signal.

A controlling method of a video recording apparatus, the method comprising:

• obtaining, by a motion detection controller, sensing data in a digital format at specific intervals based on a reception signal of radar;
• determining, by the motion detection controller, signal strength of the reception signal based on the obtained sensing data;
• determining, by the motion detection controller, target data based on that the signal strength is greater than or equal to a threshold strength;
• outputting, by the motion detection controller, an activation signal when a number of the target data is greater than or equal to a first threshold value;
• and
• activating, by a main controller, a camera based on receiving the activation signal.
