Water Spots on Dome

[Guest]

Archived from groups: alt.comp.periphs.webcam (More info?)

Has anyone had experience with water spots (actually preventing) on dome
cameras? I have a Vicon Surveyor and after a rainstorm I get some water
spots that are annoying as the camera is not readily accessible to clean.
Have you tried Rain-X or car wax or Pledge Spray Wax or anything else that
might work without damaging the acrylic dome. Open to any suggestions, put
on your thinking caps...

Interesting - I have water spots on mine at the moment, and keep meaning
to lean out the window and polish with a clean soft rag. Be interesting
to know if there's any way to prevent them in the first place.

I've done something to my webcam where i took the front of a plastic
ziploc bag and tightly put it over the lens, so that there were no
wrinkles, i dipped the webcam in a bucket of water and it worked
perfectly, make sure the bag is airtight. Even though the cam I was
using was only around $10 we still made sure that the bag was
secured. The bag drys up real fast so you shouldnt have to worry
about water spots.

You need something to beakthe surface tension of the water
droplet. Soap, dishwasher detergents and such do this well. You
could try coating the dome with windex and not wiping it off.
Same for something like Calgon. You would have to recoat from
time to time as the coating would eventually wash off.

anti fog cloths,,, by rainX maybe, did/doing that experimental here for
a window that a network cam looks out - glass tends to get exterior dampness
from sprinkler system, a misting fog fills an atrium area and teeny tiny
water spots the exterior of the window badly - seems to prolong cleaning so
I guess it helps,,, rainX seems to cause tiny drops to coagulate together
for bigger spots.

supposedly rub a mirror with bar soap and buff and it wont fog from the
shower.

They can put a hydroscopic(sic) coating on plastic sunglass lens's to shed
water which works extremely well on sunglasses - maybe one of the vision
centers can coat it too ?

Tnx for the input. You confirmed what I thought about Rain-X that it would
coagulate into bigger drops. THat may not be too much of a problem if the
the drops run down to the bottom of the dome, which I don't use much at all.
The dome is located 200 miles away and is easy to get to when I am there but
I only go there every other month during the winter. I'll check with an
oculist to see if he has anything, good idea...any others ???
Thanks,
David Gerard

so from this i have learned there could be a problem with water droplets on
a dome cam....
cool... a good way to find out rather than setting up a cam a few miles away
just to find out i have to borrow a ladder to clean it from time to
time...best to start as i mean to go on and sort it as i fit it..

but what method is best? in the past i have placed a good sized rigid
perspex sheet over the camera to stop the rain getting near it.. and in most
rains it does work, but driving sideways rain is a different matter,,,so a
dome in a dome with window wipers externally fitted. just to be safe..

so i guess its time to invent that down wiper i have visioned in my
head....??

thanks all who commented you have started me off on my strange inventions
again..but i can see it working...cheers
