A Camera is an electronic recorder of visual images, either as single frames or sequential motion pictures, stored on standard computer datachips. Each chip can hold more still images than you are likely to need, or several hours of full-motion video. Basic models cost around Cr200 with minimal extra features. Units that cost Cr1000 or more usually have 100x zoom lens, low-light capability, remote control, etc. Most models mass about 0.5kg and fit in a pocket.
