One-Button LockDown does it all; it is fully compatible with existing card access and security camera systems, and can easily be added or integrated as an upgrade to almost any existing security system. The nature of a crisis may be impossible to predict, but you can prepare for it with a broad range of options allowing for a comprehensive LockDown. It can be initiated from a variety of devices such as: iPad, a Smartphone, a click of a mouse, a hard-wired panic button or an IP telephone system and more.
