ON-CAMERA TAMPER DETECTION

Abstract:

Methods and systems for detecting tampering with or to a video camera that are performed at the video camera. An illustrative video camera for use in a security system may include a housing for housing an image sensor, a lens for directing incoming light towards the image sensor, a plurality of tamper detection sensors each providing a sensed value, a controller, and a memory operatively coupled to the controller. The memory may store a set of normal sensor values for the plurality of tamper detection sensors. The controller may be configured to repeatedly poll each of the plurality of tamper detection sensors to receive a set of current sensor values and to compare the set of current sensor values with the set of stored normal sensor values. The controller may be configured to issue an alert when the identified one or more differences meets one or more predetermined criteria.
