I’ve had the same old cam for about five years, and was disappointed that I couldn’t get a better picture on the fishtank. Surely there had been advances in technology since my last purchase right? Right! Logitech Quickcam Pro 5000 – actually has more bells and whistles then I need (comes with microphones, headsets, goofy comic facial recognition system) but the picture is beautiful and it also has a low-light setting on it. $30+shipping on ebay, sweeet!
That blue glow that you’ll see until about 4:30pm is the blue led moon lights. The metal halides turn on at 4:30PM and keep going until about 2:30AM (my home hours).
