Dies after a while
2009-06-21I've purchased a casio camera and it comes with this battery. I tried to charge my camera after not using it for a few months, and it didn't work. I called casio tech support and they just told me to buy a new battery.

Casio NP-20 Rechargeable Li Ion Digital Camera Battery
2009-05-30Haven't actually used the new battery - purchased as a spare. Hope it is better that the original battery supplied with the camera (Exilim). Battery has a sporadic performance history, sometimes failing to recharge. Rating 3 stars based on product history since it has yet to be used. Would rate seller with 5 stars as the product arrived ahead of schedule using the Free Shipping option.

My camera works again.
2009-05-17the original battery that came with my camera crapped out on me. When I went to charge it, the light indicator on the battery charger just blinked and I couldn't get my camera to work after "charging the battery" for 24 hours. I read this is a known problem with this camera battery, so I bought a replacement battery and my camera works again.

CASIO EXILIM BATTERY review
2009-04-05The product itself is good in that its lightweight, small and compact and is rechargeable. Not to mention is recharges fairly quickly and lasts quite a while. However, its not a good product in how the battery dies after a few weeks of inactivity and you have to buy a replacement. not everyone will have a need to use a camera every week... they should have a longer period of inactivity before dying. However, at least the batteries are fairly cheap when purchased online.

NP 20 lithium battery
2009-04-03this was a total waste of time. I bought the battery to replace one which had was dead and the new one was just as dead as the old one,. I was ripped off because the battery sent was dead. I checked the charge with a reading monitor and after it was charged it was dead as a door knob. Be careful about someone offering you a battery because probably the only reason they are selling it is because it was dead.
One star rating only because I could not do zero stars.

Audio & Video Connections Guide
" For a list of all the ways technology has failed to improve the quality of life, please press three." - Alice Kahn
This quote is certainly applicable to consumer electronics. From the very first commercially produced radios to the latest in high-definition television technology, the manner in which the components used to deliver our news, music, movies and entertainment are interconnected seems to have escaped logic. For both the newcomer and the old hand alike, connecting equipment in the most efficient and effective manner can be a painful chore. It is hoped this article will improve your background knowledge concerning potential A/V system connection schemes and where each is most appropriate. The next time you find yourself in a "connectivity quandary" perhaps the ideas shared here will help you to quickly solve the riddle of which wire goes where and why!

Professional video camera
A Professional video camera (often called a Television camera even though the use has spread) is a high-end device for recording electronic moving images (as opposed to a movie camera, that records the images on film). Originally developed for use in television studios, they are now commonly used for corporate and educational videos, music videos, direct-to-video movies, etc.
There are two types of professional video cameras: High end portable, recording cameras (essentially, high-end camcorders) used for ENG and EFP image acquisition, and studio cameras which lack the recording capability of a camcorder, and are often fixed on studio pedestals. Portable professional cameras are generally much larger than consumer cameras and are designed to be carried on the shoulder.
Technology
It is common for professional cameras to split the incoming light into the three primary colors that humans are able to see, feeding each color into a separate pickup tube (in older cameras) or charge ...
