Intercom - VOIP & Analog
  A key tool for a safe and secure facility is the use of intercoms.

An intercom can be used to screen persons prior to entry to a facility. Intercoms can also be used as a call box in a parking facility or for a patient to call a nurse.

Having the capacity to quickly and easily communicate to a security personnel, nurse, or responder can dramatically save lives and property.

Intercoms also have additional features such as remotely opening a gate or door.  Intercoms can be used as a commercial quality sound system.
 
 
     
  IP Network vs. Analog Intercoms
