Wireless Sensor Networks have been widely used over a period of time for observation and surveillance. Wireless Sensor Networks are the combination of different sensors built on a tiny embedded device for specific observation such as temperature, humidity, pressure, motion etc. of a subjective region. This paper presents a unique method for customizable design and implementation of `Wireless Image Sensor' for surveillance and monitoring purpose. The image sensor OV7670 captures 8-bit raw RGB image of resolution 640×480 which provides visual information and implement a simple surveillance and monitoring application. There are several challenges in image sensors which have been discussed in this paper such as encryption, transmission and processing speed, power efficiency and computational cost. Implementing wireless image sensor on Arduino Mega board provides an affordable and reliable platform for visual surveillance. The Zigbee transmission protocol provides encrypted transmission over a wireless network. The implemented hardware of visual sensor gives a clear insight on wireless image sensor based on microcontroller. The results elaborate the usefulness of wireless sensor networks in the proposed area of research.
