Pros: The cameras look small and discreet. We have a neighbor who keeps trespassing on our property and stealing things. We know it's him, but we need proof. So we've installed these cameras, and I don't think he can tell they're there. Of course, nothing's been stolen since the cameras were installed, so it's possible that he DOES know they're there. But it's also possible that he hasn't gotten around to stealing from us since the last time (things weren't going missing constantly - just once or twice a year, and we'd find eerily similar items in his yard a few months later). Either way, we installed the cameras. You can barely see them, but they cover a wide swath of property, and if he does try that again, we'll get him.

Cons: I wish I had more cameras. 4 cameras covers most of our property, but not all. Still, it's very impressive for their size.
