This invention satisfies a need for surveillance of any fixed or mobile location from a 4G wireless terminal or cellular telephone equipped to view video. The surveillance device consists of digital video cameras, microphones and alarms interfacing a control unit which has the ability to time stamp and store all camera outputs on a storage device, recognize alarms, send alarm status to a remote wireless user, receive wireless calls from the remote user and act on remote commands to transmit any camera output occurring during a time period selected by the remote user. The latter will enable the remote user to document video and sound for a time interval of interest. Video and sound of this time interval may be placed in permanent storage for transfer to a portable video medium. This invention will employ the new 4G wireless network to allow a wireless terminal or telephone equipped with a video display to select the proper bandwidth needed to receive streaming video and sound from the remote surveillance device.
