Surveillance system, method of remotely controlling sensor apparatus, and surveillance remote controller

A vehicle surveillance system includes a vehicle-installed sensor apparatus for transmitting by radio, sensor information acquired by a sensor, a communication adapter for receiving by radio the sensor information from the vehicle-installed sensor apparatus and transmitting the received sensor information onto a public network, and a surveillance server for receiving the sensor information from the communication adapter. The vehicle surveillance system further includes at least one portable surveillance remote for relaying transmission of the sensor information from the vehicle-installed sensor apparatus to the communication adapter.
