Default what is the differance between PAL and NTSC..

I am contemplating buying a camera set up from http://www.rangevideo.com/aerial_video.html and they show two types of cameras although one is out of stock PAL / NTSC. what are the differances? Is this a pretty good set up for a newbie. Is there any thing better in this price range? thanks!

Default RE: what is the differance between PAL and NTSC..

An NTSC TV image has 525 horizontal lines per frame (complete screen image). These lines are scanned from left to right, and from top to bottom. Every other line is skipped. Thus it takes two screen scans to complete a frame: one scan for the odd-numbered horizontal lines, and another scan for the even-numbered lines. Each half-frame screen scan takes approximately 1/60 of a second; a complete frame is scanned every 1/30 second. This alternate-line scanning system is known as interlacing.

PAL is short for Phase Alternating Line, the dominant television standard in Europe. The United States uses a different standard, NTSC. Whereas NTSC delivers 525 lines of resolution at 60 half-frames per second, PAL delivers 625 lines at 50 half-frames per second. Many video adapters that enable computer monitors to be used as television screens support both NTSC and PAL signals.

If you plan on using this in the United States, only NTSC will work. Good news, the NTSC version is IN stock.
