I can understand why someone might want outdoor wireless IP security cameras. I sometimes think it would be nice to have one mounted in such a way that I could easily see who was knocking on my door without having to get up and look. Of course, I am aware of how lazy that sounds. It would also be nice to have one positioned so that I could see who was pulling into my driveway. There's a blind spot out there so that if a vehicle pulls far enough up, I cannot see it without going outside. There have been a couple times when I discovered a strange vehicle parked in my driveway, and this made me think that this might be a problem worth trying to solve. Having a camera out there probably wouldn't be a bad idea, especially if it could be set up to alert me.
On the other hand, I'm not sure about the indoor cameras I see advertised everywhere. What are they for? Do people aim them out their windows to cover portions of the exterior, or is there some reason one would want a bunch of cameras covering the interior of their homes? Aside from the brief fun of monitoring a pet while one is away, I can't imagine how I'd use something like this. Do parents use them to monitor babysitters? I suppose they could record criminals during a break-in and that the footage could then be used as evidence, but it seems that something more like an alarm system would be more useful there. Maybe they have other applications that just aren't occurring to me.
I once thought that such cameras would never be popular because nobody would like the idea of having cameras throughout their homes due to privacy concerns. I no longer think that is the case. There are now a variety of products that listen to everything said in one's home, and they seem to be quite popular. Many people have been perfectly willing to trade their privacy away for convenience.
Do any of you have wireless IP security cameras inside your home? If so, I'm curious about how you use them and whether you've found them worthwhile.
