Stellar occultations by asteroids and outer solar system bodies can offerground based observers with modest telescopes and camera equipment theopportunity to probe the shape, size, atmosphere and attendant moons or ringsof these distant objects. The essential requirements of the camera andrecording equipment are: good quantum efficiency and low noise, minimal deadtime between images, good horological faithfulness of the image time stamps,robustness of the recording to unexpected failure, and low cost. We describethe Astronomical Digital Video occultation observing and recording System(ADVS) which attempts to fulfil these requirements and compare the system withother reported camera and recorder systems. Five systems have been built,deployed and tested over the past three years, and we report on threerepresentative occultation observations: one being a 9 +/-1.5 secondoccultation of the trans-Neptunian object 28978 Ixion (mv=15.2) at 3 secondsper frame, one being a 1.51 +/-0.017 second occultation of Deimos, the 12~kmdiameter satellite of Mars, at 30 frames per second, and one being a 11.04+/-0.4 second occultation, recorded at 7.5 frames per second, of the main beltasteroid, 361 Havnia, representing a low magnitude drop (Dmv = 0.4)occultation.
