Conventional surveillance systems capture realtime events from cameras mounted at fixed locations. A surveillance user then monitors the occurrences via a browser at a stationary computer. To enhance the mobility at the viewer side and the camera side, we implement a remote mobile surveillance system by integrating some inexpensive techniques - an OSGi service platform, which can easily be implanted with future developed applications, a camera mounted on an embedded system which is carried by a robot - Lego Mind Storms NXT, and a J2ME based viewer and controller program on a mobile phone. With assistance from modern wireless networks, surveillance users can handily monitor the remote events in a wider viewing range at anytime and anywhere.
