ratio rises for all of the approaches since progressively more
of an event area is covered, and, with the proposed approach,
a maximal value is obtained. This is because we judiciously
selected the SLs in the monitored region. Likewise, the
redundancy ratio values were found to be less in the proposed
approach than in the others, as is evident in Figure 6(b).

CONCLUSION
This article presents a novel approach, e.g., CMT-MDSD,
based on SL determination for lowering the number of cameras activated and thereby maximizing the event region covered.
In this scheme, the entire monitored region is segregated into
a number of virtual compartments. In each of the compartments, the minimal mean distant scalar is elected as the SL of
the concerned compartment. These chosen SLs operate as representatives of the other scalars for conveying the event information to their corresponding camera sensors. Then the
camera sensors collectively decide regarding their actuation.
From extensive experimentation, it was observed that our
approach attains minimum camera activation along with maximal
event area coverage in comparison to other approaches. While
varying the number of cameras, the maximal coverage was found
to be 93%, with the redundancy minimized up to 26%.
