A method, device and/or a system of centralized management and emergency allocation of deployed defibrillators each having associated communication modules. A central server may process a message from a communication module associated with a defibrillator, and then analyze a photograph and/or a video of a defibrillator display to compare it to a set of expected visual markers using a pixel algorithm of a pixel analysis module. The central server may then determine the operational status of the defibrillator such as whether it is in a nonfunctional status. The central server may then send alerts to the communication module and notifications to the an organization owning or leasing the defibrillator. The central server may also send alerts to the communication module based on a nearby emergency call, provide geospatial mapping of defibrillators to improve deployment efficiency and/or establish bi-directional communication between the operator of the defibrillator and a medical professional.
