Hi every one, I am new in the CCTV field and have a lot to learn. I have to choose a camera enclosure for desert conditions (extreme temperature 45° C in the shadow and more under sun light, frequent sand storms). I naturally think to use a seled enclosure to avoid sand to enter because of frequent sand storms. how can we evacuate heat if the enclosure is sealed (a fan will be useless). Thank you in advance for your help. Zyrius
