Attach Motion Sensors and Window Door Sensors where you want and need to detect events. The Swann Security App will notify you of movement involving heat and motion from people and/or pets. Use Swann's sensors to monitor entrances, thoroughfares, spaces requiring authorized entry, anywhere beyond your line of sight to detect motion, movements and much more. Swann's Alarm System can be integrated into a complete security system with your Swann Security IP Cams, or DVR and NVR systems - all managed on the Swann Security App. Add your Cams and Smart Sensors to the Indoor Siren for an audible and visible alarm. This is a powerful deterrent for intruders. Color: White.
