Astronauts on the International Space Station inserted an effervescent tablet in a floating ball of water to test a new device that can record four times the resolution of a normal high-definition camera.

As IP-based video systems continue to gain widespread popularity in the video surveillance market, one of the benefits is the ability to capture high-resolution images through megapixel video. Also emerging is use of the HDTV standards that are prevalent in the consumer video market. The images produced by this new generation of cameras are often collectively referred to as high-definition (HD) or as megapixel images. Because the terms HD and megapixel both indicate an improved level of imaging performance compared to traditional analog images, they are often thought to be the same. But, there is a difference.

The Illustra 400 Series of IP cameras have 2/3 megapixel resolution, which is perfect for those who want enhanced resolution over standard 480 x 640 pixel resolution but who are not ready to make the jump to megapixel cameras.
