Re good camera in the dark...without flash

I have shot a photo with NIKON COOLPIX L11. The image has lot of background noise even in back environment (little red white spots noise on the surface). I only what the light spots which I cast/project onto the surface of the object. Here is link. http://community.webshots.com/album/562147898TNlijW?vhost=community

Any suggestion on what camera Model should I buy? I am not good at camera knowledge. Thks!!
