Perimeter Connect is the modern, self-programmable dog collar built for homeowners who already use an Invisible Fence brand system and want full control without dealer visits, confusion, or extra costs. Unlike traditional replacement collars, Perimeter Connect automatically adapts to your existing Invisible Fence brand system, so there's no need to identify your model, frequency, or collar type before purchasing. If you have an Invisible Fence brand system, Perimeter Connect handles the rest. Using the Perimeter Connect Bluetooth app, you can set up and program your collar in minutes. Adjust correction levels, manage settings, and make changes anytime, right from your smartphone. No professional installation. No subscriptions. No service calls. Comes with two collar batteries. Choose the power option that fits your lifestyle, with either a rechargeable collar or a replaceable battery collar. Built by Perimeter Technologies and engineered in the USA.
