Our Security systems are unlike all others. In an invasion statistics say you have 30 seconds in the daytime and 15 seconds if asleep to decide what you're going to do. Our alarms go off when some one enters and most do not go off for 30 seconds, losing valuable lifesaving time. Ours has a security button you keep by your bed at night or with you within your home and when pressed you have two way audio to 911 and at the same time a security light will be flashing outside and scare an intruder away, because it can be seen inside flashing outside and it will allow the emergency responders to find you much quicker. Our security system works with VoIP, ISP, Cell and Landline all for a one time price of $299 + $15 shipping.
