Your high tech baby monitor could let crooks know you're not home -- or even worse. A Harris County family says its baby monitor was hacked and the hacker started cursing at the baby.

Is nothing safe? Security expert Keith Squires says no.

"What you're hoping for with security cameras is being secure and it seems like maybe just the opposite is going on when someone can actually see inside your home."

Squires says baby monitors with web cams need a user created login and password -- don't just use the default settings. He says older monitors with just audio can be monitored by your neighbors, because they're on the same frequency as cordless phones.

"There are many that are secure but I think there probably are some of the earlier versions that didn't provide the type of security that really was necessary and there are probably plenty of those still floatin' around."
