The Smart Phone Alarm can be operated using your own iPhone/ Android Smart Phone or via a standard PC web browser. Upon triggering the PIR camera can take an image of the room & send it direct to your phone for visual confirmation of what has caused the alert. Upon alarm triggering the external siren will start sounding & you will be notified by email & push notification (i OS only) on your smartphone. There is a wide range of accessories available for this system including the clever power switch accessory allowing you to turn lights appliances & other electrical items on & off using your smartphone
