Herein disclosed is a surveillance system, comprising: a camera unit for transforming an image into an image signal and outputting the image signal, and a display unit having a screen and operative to transform into an image the image signal outputted by the camera unit to display the image on the screen. The camera unit is operative to automatically chase an object as a chasing target to have the display unit display the object as the chasing target. The display unit includes marker displaying means for displaying a marker on the screen; and chasing target determining means for determining the object spaced apart from the marker at a predetermined distance as the chasing target among the images displayed on the screen.

Surveillance system for watching an object through an image

An appliance maintenance apparatus for contactlessly detecting the operation states of appliances and operating the appliances in response to the operation states of the appliances, and an appliance remote maintenance system which comprises a plurality of appliance maintenance apparatuses, and a remote diagnosis control apparatus which is communicatable with the appliance maintenance apparatus through a public network to ensure the remote diagnosis control of the appliance maintenance apparatus from a remote place.
