A camcorder can get as hot as the interior of your car on a scorching, summer day, which, if you read the small print on most video cassettes, the manufacturer warns against. Don’t leave the camcorder inside your trunk or hot vehicle. Scubacam and Camera Essentials have a line of sun and dust covers made of silver, reflective 4 oz. nylon. Space blankets or old, white T-shirts, clipped together with plastic spring clips, will work in a pinch.
