It is well beyond the scope of this paper to further analyze this class of algorithms and techniques and how they are integrated and implemented in fire detection software applications. Nevertheless any early fire warning and monitoring system should consider carefully the above design and software component issues see ESA 2008 Tartakovsky Veeravali 2004 . Finally it is stressed that in the current literature assumptions include discrete samples binary messages and synchronous communications between the fusion center and the sensor devices. The approaches concerning continuous time processes require additional sampling quantization policies. For example fire and flame flickering is time varying and can be modeled as a continuous random process Markov based modeling approach . In these cases and due to power and transmission constraints the Remote F D Central Node receives data in a sequential fashion and the goal is to quickly detect a change in the process as soon as possible with a low false alarm rate. On the other hand bandwidth limitations require efficient sampling and quantization strategies since canonical or regular sampling may no longer be optimum. 5. Integration with First Responders communication systems It is important in this subsection to take a step further and raise the complex issue concerning First Responders FRs needs with respect to communications interoperability extending the scope of the proposed fire detection surveillance system. This aspect which in our opinion is not usually addressed in various proposed detection surveillance systems is highly important and operationally critical to any designer who needs to consider a fully realistic high level integrated architecture. In the case of large fire disaster and crisis outbreaks it is highly .
