Always know when an intruder is detected in your home with the Kangaroo Siren Smart Keypad Alarm. Compatible with Kangaroo’s sensors, this device makes an audible noise when the sensors detect a trespasser in your home. In addition, Siren works as a base station for your whole Kangaroo security system. You can also use the integrated keypad to manually arm and disarm your home when you are away from your phone. Moreover, each family member can have his or her own unique PIN to access the keypad. The smart keypad alarm even provides two Roo Tags, allowing guests to disarm the system with a single tap. Using the app, you can arm and disarm the Siren alarm from your mobile device.
