The only drawback to those is if someone ever gets your IP info.......ok I like to play devils advocate

There are cameras where I work. If you have the IP address you can go to it from any computer anywhere in the world.
Herb, I think thats the right way to go.Some people are afraid no matter what.
I am still considering a few cameras but I admit I don't put a lot of faith in them. Mine would be well hidden. If you come to my house I promise there won't be any in the bathroom.
Guess what else you can do remotely? Here is screenshot of my ipad. This is my home thermostat. I don't pay a monthy fee for this. When I put in my heat pump last week I added a redlink thermostat. The ipad goes to a honeywell server and can look through wifi at my thermostat. The thermostat itself is much more complex than this, but this free app lets me adjust temps, set schedules, look at outdoor/indoor temps and humidities.
