Hi All,
Thanks for the comments, and Striker well best of luck, I tried a Peltier and had it bolted directly to the 1/4" mount thread, but found that it could not cool the whole camera (required as the CMOS chip is a long way in) the Peltier went down a good 20 C. below ambient, but as the Camera is of Plastic construction theres not much thermal conductivity, anyway it will be interesting to see your results, I used a large heat sink- no fan (to get away from vibration) and that bit worked well, unless you control the current to the Peltier it will run-away, I t did some tests to find the optimum Voltage/Current for stable operation and left it at that (6 V. at 2.1 A on a 12V Peltier) another way to go is stack the Peltier devices, a smaller one on the main Peltier, this will bring down the Temp. a lot more, but requires more Watts from your power supply.
cheers.Jim
