Figure 4—With only six chips costing less than $16 in small quantities, I developed a full-featured analog video motion sensor. The chips include an ATmega88 as the main controller, an AD9280 ADC, an LM6134 high-speed quad op-amp, an LM1881 video sync separator, a 74HC4066 as a simple analog switch, and an RS-232-level converter.
