The megapixels of webcams of a comparable age and spec to this webcam range from 0.3MP to 20MP. The Konig IP Camera has one of the lower megapixels (only 0.3 megapixels) amongst webcams of this age.
Other 0.3MP webcams currently available which you might want to look at include the PLCM37FRV, or the PLCM38FRV (£19.79) both from Pyle and both of which are cheaper.
If you would prefer a higher megapixel then you might want to look at the HP 2100 (£18.99) (1.3MP and higher rated), or the Logitech C525 (£27.05) (8MP and higher rated).
