One issue with tubes apart from the restricted viewing angle is that insects
love to use them for their egg laying etc, so they tend to get bunged up
with stuff.

JakeD formulated the question :
I'm installing a number of security cameras on the external walls of
my house. I am interested in also installing some sort of rain
protection for same. The first thing that sprang to mind was to use
inverted quarter- sphere uplighter housings. However, buying the
housing alone without the light-holder and other gubbins is not easy,
and paying out for the full enchilada can be pricey - when you want
six! Can anyone suggest anything else?

Cheap as chips halogen outdoor flood light units - just take the lamp
out and point the camera through the glass fronted housing.


Thanks to all for the suggestions. My cameras are already supposedly
weather-proof, but I am thinking that rain drops collecting on the front
lense could be an issue. I am hoping not to put any extra glass in-between
the camera and the target area, because my cameras have IR LEDS, which I
think would be reflected back at the camera by glss. The 110mm plastic
pipe
idea seems worth exploring.

I've had Swann wide angle cameras installed for a few months and not noticed
any rain problems and we've had quite a bit. Must be similar to the amount
of dirt that window panes pick up. I notice the LED's have a limited life
10,000 hrs I think, so the cams will need renewing after a couple of years
anyway and won't need cleaning in the meantime.
