you get what you pay for....something that will stand up to rp weather,vandal resistant,give a good picture,be remote controllable will end up costing you a grand....or you can buy the cheap ones like frys has and just keep changing them out...not sure which is the best way to go...
I agree and the cost really isn't a factor (within reason). I just want to find something that will give a much clearer picture. Being controllable would be neat but isn't a must.
A couple of the articles that I saw on the topic indicated that you could use a video camera....get high def and a good lens...just need to find one that lets you stream....if you put it outside, you'll definitely need some kind of enclosure....
