INTELLIGENT DVR USING A GRAVITY SENSOR, PARTICULARLY FOR RECORDING LOG INFORMATION BY SENSING EXTERNAL SHOCK AND LOCATION VARIATION

摘要

PURPOSE: An intelligent DVR using a gravity sensor is provided to enhance the security function thereof by securing the stability for external shock and rapid movement and providing accurate information through information storage and alarm functions.;CONSTITUTION: A key input unit inputs the setup of a user, and an impact sensor(110) senses the external impact. Based on the sensing results of the impact sensing unit, a controller(130) is operated in a security mode or a security mode. If the security mode is selected, the controller records the log information corresponding to the external shock of the impact sensing unit. A storage unit(140) stores the log information, and a communication unit(150) transfers an abnormal situation information corresponding to the impact sensing.;COPYRIGHT KIPO 2011
