Abstract: An apparatus for providing secure access to a trailer connector includes: a cover, a locking device, and a controller. The cover is configured to be secured to a trailer and to cover at least one connector of the trailer. The cover has an open position in which the connector(s) are accessible and a closed position in which the connector(s) are inaccessible. The locking device has a first state configured to hold the cover in the closed position and a second state configured to permit the cover to move from the closed position to the open position. The controller is configured to cause the locking device to change from the first state to the second state, to permit the cover to move from the closed position to the open position, based on an authorization.

Abstract: An exemplary central system is configured to receive and store data from a registered device passing through an entryway of a restricted site, in a manner that permits the detection of unauthorized entry into the restricted site. A beacon broadcasts a beacon signal which prompts the registered device to transmit an active device ID and an active location ID to the central system, a sensor detects movement approaching the entryway and notifies the central system, and a camera captures an image of a region encompassing the entryway. The central system is configured to, among other things, receive the notification, communicate a control signal to the camera to capture the image, receive and store the image from the camera, cross-reference the active location ID with a registered location ID, and cross-reference the active device ID with registered device IDs. The entryway may have a barrier or may be barrierless.
