To clarify my point.

There are lots of ways to keep an external CCTV camera housing clear from moisture and condensation. You can either vent out the moisture and air and balance it with the relative humidity of the ambient air external to the housing or you can trap the moist air inside and try and deal with the problem with silica gel bags etc. I do have experience of both and have experimented greatly so my remarks about venting this housing are well founded. I actually experimented with this housing six years ago and found it readily misted up!

If you had a damp problem in a house you would prevent further damp getting in the house then make sure the ventilation is good. Blocking off ventilation is sure fire way of creating damp problems.

Natural ventilation is a good option, it

for that. And by the way i drilled some holes at the bottom and so far touch wood it seems to have solved it
