Complete light curves of the short-period RS CVn system SV Cam are parameterized for a circular, dark starspot model. The observational data provide a time baseline that spans over 50 years and so provides information that pertains to magnetic activity cycles of the system, which is presumed to center on the primary (G3 V) star. For each light curve that contains sufficient information, the longitude, latitude, and area of the spot group are computed for a fixed temperature ratio (0.65) of the spot relative to the photosphere. It is found that:(1) one spot group accounts for the visual distortion wave effects; (2) the spot groups fall into two zones of longitude, which are interpreted as active longitude belts; (3) the differential rotation rates within these belts are much smaller than for the sun; and (4) the spot groups tend to lie at high latitudes and certainly above the corotational latitude most of the time. The frustrating gaps in the data point out the need for high-precision synoptic observations of this and other short-period RS CVn systems.
