The Boundary Plus Smart™ System App works seamlessly with the Boundary Plus Smart Containment and Freedom Solutions to provide unsurpassed confidence that your system is operating at optimal levels. The Smart Doorman™ provides your pet the independence to explore your yard as needed while the containment system provides you confidence that they will remain securely in their Safe Area. The containment system provides both indoor and outdoor solutions for your pet including the ability to: - Set an Invisible Boundary® Area allowing your pet to fully enjoy your yard while giving you confidence that they are not leaving their Safe Area. - Set Safe Zones using SmartShields™ Devices to block areas where pets cannot go such as flower beds, the sofa, a child’s room or a trashcan. Overall, the system allows you to enjoy your pet more and worry about them less. With our latest technology, we have created an app which provides information on the system so you can be confident the system is working, and your pet is secure regardless of where you are. The app tracks: - Strength of your boundary wire - Battery life on all devices - Wi-Fi connection - Whether your pet is inside or outside (only available with installation of Smart Doorman™ Unit) All of that is displayed at a glance so you know the system is working well without moving from the couch or leaving your office. The app also provides notifications on maintaining your system including - Prompts to charge/replace batteries - Early indications if you need to contact your local dealer for a service call - Check your Wi-Fi connection If there is a critical issue, you will get a push notification alert, so you react quickly even when not at home. Critical alerts include - Wire breaks - Your dog leaving the Safe Area Equally important, you will get a notification when the issue is resolved. In addition, if you have the Smart Doorman, you will also be able to change the door from locked to unlocked to auto mode from your phone. If you notice something unusual or have other system questions and need to contact your local dealer, their information is contained within the app so you can easily get in touch with them. You can also share the app with other family members so everyone in the house can know your pet is secure and happy in the yard.
