    Always be aware when invited guests or unwanted trespassers visit your property or enter a restricted area. The Defender FrontLine Wireless Driveway Alert System notifies you when motion is detected up to 30' away so you never have to worry about people sneaking around your property without your knowing. As soon as the motion sensor detects motion, it sends a signal to the parent unit which sounds an alarm to notify you that someone has entered your property. You can even adjust the settings for a smaller environment to safeguard an important area of your home or business. The system is expandable, allowing you to use up to 3 motion sensors with the 1 parent unit (additional motion sensors sold separately) so you can easily protect more areas of your property. With the Defender FrontLine Wireless Driveway Alert System, you can rest assured knowing when your children come home at night or when someone enters a private or restricted area within your business.
