Wireless Micro-Camera includes camera (.900 inch square x 1 inch deep) with adjustable-focus lens, internal microphone for sound transmission, camera connector for 9v battery or wall transformer, 2.4 GHz video/audio receiver, 2 wall transformers, camera mounting plate and cable for connection to VCR/TV.

Wireless network sensor consists of small acceleration sensors connected to radio transmitter-receivers and a base unit connected to a PC with RS-232C (USB and Ethernet available). All of acceleration waveform data from sensors can be stored in a HDD of the PC. Each sensor works as an autonomous communication node and makes self-assembling into a network of sensors. Intermediate nodes assist distance nodes to reach the base station.
