Camera Types
Helmet cameras generally fall into two main categories; CMOS and CCD type. Although helmet cameras take on a variety of forms the majority are small cylindrical cameras resembling a tube of lipstick or a bullet, coining the name lipstick and bullet cameras. Helmet cameras may be connected to a video recording device with video input capability, such as a handheld camcorder, or purpose built digital video recorder.
CCD helmet cameras are based upon the charge-coupled device (CCD) image sensor. They typically operate on 12VDC power and output an analog type signal. These cameras draw more power than CMOS cameras but offer superior picture quality and better color replication.
CMOS helmet cameras are based upon the complementary metal–oxide–semiconductor (CMOS) image sensor. They typically operate on 5VDC and draw very little power. CMOS cameras are also generally smaller than the CCD type. CMOS cameras do not offer the same clarity as CCD type and generally do not work well in low light environments.

Famous quotes containing the words camera and/or types:
“The camera has an interest in turning history into spectacle, but none in reversing the process. At best, the picture leaves a vague blur in the observer’s mind; strong enough to send him into battle perhaps, but not to have him understand why he is going.”
—Denis Donoghue (b. 1928)
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
