This is my first choice among all other products with a high price tag. Most other security cameras are designed to be fixed in one direction, whereas this one detects motion and sends an alert. It also has a sound alarm option, but it's too sensitive and annoying. With this price range, I think it's the best choice. The only kicker is power cable is too short that it should be only installed within 3 feet from an electric outlet. I did some homework and purchased an extension cable. After installation, I changed the password. Highly recommends this.
