I've found that the rain is only a problem when it falls close to the 
camera lens. So an extended hood over the front of the camera keeps the 
critical area clear. Mind you, we haven't had any rain for many weeks 
here in Australia :-(

Now spiders are a constant problem, particularly the webs. The only 
solution we've had is a weekly brush and spray. I wonder if the IR 
attracts the spiders?
