A wireless multi-drop IPT security camera system

This paper presents the design of an IPT security camera system with the integration of a secure wireless communication scheme. Two innovative circuits known as an LCL tuning circuit and a multi-phase interleaving system have been applied to the design of the IPT pick-up circuit. A wireless local area network (WLAN) using 802.11 g protocol has been chosen to realise the high bandwidth communication scheme which supports multiple cameras to operate simultaneously to form a multi-drop configuration. An experimental prototype has been built to verify the proposed concept.
