Hi, Thanks for your great website.
I'm a newbie looking at purchasing a 2 or 3 MP IP PTZ outdoor camera with 20x zoom. I have come across these two product on here.
Product# IPPTZ-EL2MPL20X
dome style
Product# IPPTZ-EL2MPIR250L20X
turret style
I will be mounting it on a hill overlooking our 100 acre property and want to be able to zoom right into detail across the valley.
However, why the two different styles and what are the pros and cons of each style.
I'm concerned that strong sunlight on the dome will wash out the image in places and also may distort the image as it introduces another "optic" element in front of the lens.... also, something else to keep clean?
However, I'm also concerned that the turret style camera is not insect proof. If you saw the size of our spiders in Oz, you would understand my concerns. Don't forget, as lil'uns, they can easily get into vent holes and open joints.
Many thanks

I'm just a member of the forum, not SCK support. The two PTZ's you're looking at are mostly different in that the dome camera has no IR and the torrent dome does. So, is night viewing important to you? If it is, you'll need to go with the torrent dome camera with IR. The camera without IR will go black if there is no exterior light outside. Now, IR will attract spiders so that is also a concern. But if night viewing is not a priority for you, you can turn the IR off, so that still makes that camera consideration to choose. Dome cameras can be susceptible to sunlight distorting the image at some angles and at some times of day- usually in the morning if the sun rises and throws sunlight right at the camera. But since the camera is a ptz, you can adjust the positioning of it to help avoid a problem, whereas a fixed camera you'd be stuck with the problem until the sun migrates across the sky a bit. The torrent dome doesn't suffer from that problem. Either camera needs wiping to clean it occasionally. But dome images tend to get more effected during rain that the other torrent dome type. Both suffer from getting a distorted image in the rain, but domes tend to be worse in the rain believe it or not. As far as spiders just making a home in one, both have ample room for that. Good luck.
To solve the non-IR problem on the dome, you can install an illuminator that would solve that problem. If shockwave is correct about IR attracting spiders, you can install the illuminator away from the camera and still point it in the direction you want to see at night. Here's the link to the illuminators.

That is a possibility. However- "I will be mounting it on a hill overlooking our 100 acre property and want to be able to zoom right into detail across the valley" - You have to be realistic about your expectations, both with zooming distance and certainly IR throw. Those IR fixtures will only get you so far, well short of what you want.

Thanks for your comment guys.
I don't need IR as there is nothing worthwhile viewing at the distance the IR will illuminate.
I see several pros and cons of the 2 styles, but having no experience, the concerns may be more imaginary than real and I'm hoping your hands-on can point me in the right direction.
I imagine the plastic dome could suffer from light flare, especially in winter when the sun is low and compromise the quality of viewing.
It may also get quite a lot hotter... just like a glass house. The IR turret style being white, may keep it cooler.
The plastic dome styles are generally cheaper however, and the money I save could go into a better zoom or extra pixels, giving a better viewing experience overall.
Comments ???
Many Thanks.
