Camera Domes

The only problem with the sharp cctv camera is the first baseball size hail will destroy it ! But yall are thinking out of the box now !
 
How far upward does the camera need to point? How about using a wide acrylic cylinder with a flat top made out of something strong enough to withstand hail?
 
Does anyone monitor their camera through a small lcd screen as opposed to running into a computer? At the moment I don't think I'll stream from the roof cam (if I build it), and would like to avoid needing a computer for monitoring the video. Mainly interested in the car acting as a mobile tripod of sorts. I've come across a few little lcd monitors, but was wondering if anyone else has anything like that, or any ideas of something that might work. If I do decide to stream, I was thinking about throwing one of the GoPro cameras up there.
 
Since my original post I made yesterday in the marketplace thread was deleted (the one that Skip got his avatar from) I thought I would just leave this here:

I've carefully considered the two plastics. The problem with polycarbonate, despite being much, much stronger, is that it scratches more easily, it yellows in the sunlight, and it costs A LOT more. My $65 acrylic dome costs $195 to have made out of polycarbonate. Even if I wanted to spend that much, the yellowing and scratching make it impractical for the application. For hail protection, it definitely makes sense to use polycarbonate (although those sheets are super expensive too), since you want the strongest material, and it doesn't need to have perfect optical qualities.

Thanks for the tips, Skip! For what it's worth, the polycarbonate panels I've used on all of my hail guards haven't yellowed in 5 years. I think that happens with constant exposure to sunlight over a period of years. In most cases, this dome would only see a month of "action" each year and be stored away the rest of the time. But I definitely agree on the scratching issue...you have to be much more careful with it. And from what I've read, polycarbonate can't be polished like Acrylic can if it does scratch. So, it's a toss-up. I think I'm willing to sacrifice a little video quality and spend a little more to know I won't be destroying a $500 camera and motorized head.

I *try* to avoid hail cores too...but they don't always avoid me! :p
 
Great thread!

As I was reading about polycarbonate domes I thought of the polycarbonate eyeglasses I got this past year and how well they have held up. I got the anti-scratch coating and the stuff works very well. So I Googled it and found a product called Vueguard 901WC. It is a scratch and abrasion resistant coating formulated for polycarbonate and acrylic. It is also available in an anti-glare formulation. I don't know if this might help extend the useful lives of your domes or not, but I thought it might be worth looking at.

Yes, I have a small monitor (looks like a garmin gps screen) that is on my windsheild. I got it on ebay for like $15. I run the AV from my camcorder to this.
But I also stream so i run my firewire as well to my camcord to the laptop to stream live. I connected the screen to a toggle switch when i want to turn it on. Here is a example: http://cgi.ebay.com/Mini-3-5-TFT-LC...itu=UCC&otn=5&ps=63&clkid=7267666548902459499

That's right Jeff, I remember you saying something about that now. That's a lot better than the ones I was looking at... most of them were around $120 to $200. Don't really need anything super nice for this application, only need to be able to see what's going on to compose nice shots.
