Abstract: A mobile transceiver having selectable travel modes and a method of operation are provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver having a processor, and a wireless transceiver and a satellite receiver each coupled to the processor, the method comprising: sending a message to an asset tracking service, the message from a mobile transceiver including a device identifier (ID) associated with the mobile transceiver; receiving a message from the asset tracking service, the message including an instruction for the mobile transceiver to apply a selected travel mode; and applying the selected travel mode as a current travel mode.

Abstract: A method and system for converting privacy zone corner points in a still image to PTZ coordinates using the equations for distance along the great circles of a sphere, where the sphere is defined along the pan-tilt axes of a PTZ camera with radius equal to the focal length of the image. The method includes receiving planar coordinate data defining a plurality of privacy zone corner points, the planar coordinate data taken from a still image, converting each privacy zone corner point to corresponding spherical coordinates, converting each of the corresponding spherical coordinates to corresponding PTZ coordinates, and storing the corresponding PTZ coordinates in a storage device. The stored PTZ coordinates may then be transmitted to a computer monitor. The motor of the PTZ camera moves the camera according to the PTZ coordinates until the privacy zone corner points appear at the substantial center of the monitor screen.

Abstract: A controller for a video matrix switching system may include at least a first multiple purpose unit (MPU) module configured to provide video and control for a multi-camera video CCTV system, and at least a first port module connectable to the MPU module and having driver electronics for a set of interface ports. In some, but not necessarily all embodiments, the interface ports may include both a plurality of communications ports and one or more data line ports. Also, the MPU module may include a watchdog module configured to present an interface that monitors specified tasks and takes action when any of the specified tasks time out.
