The meshed wireless networks are those networks in which the two topologies of wireless networks are mixed, the Ad- hoc infrastructure topology and topology. Basically are topologies infrastructure but they allow to join the network devices that despite being out of range of the access points are within the range covered by any network card that directly or indirectly is within the range coverage of an access point. Type mesh networks are widely used in video surveillance applications with large number of cameras and terrain features. Thanks to technology of intelligent routing of signals , the data transmission is effected by the ” desirable ” route. In Smartech Security work only with the best teams in the specialized market for the transport of video signals, which among other advantages provide the lowest latency, highest throughput or performance and redundancy wider industry.
