For the reason that the image information can not achieve high reliable transmission because of channel interference and others’interception during transmission

a measure that based on RSA and RS algorithm and Zig Bee communication technique is proposed.The RSA encryption algorithm and the RS coding algorithm are deeply analyzed.The Zig Bee communication technology is introduced.The overall design of the Zig Bee-based image scout sensor is given.simulation and analysis is carried out by computer.The result shows that RSA encrypt then RS code before transmission has the relative lower false code rate and lower calculate complexity.
