Many sites it is impossible to connect surveillance cameras through cables due to the distance, the distances between one of the surveillance cameras and the control center may exceed a few kilometers, and here it is necessary to think about creating a wireless network to integrate all the elements of the system, wireless surveillance networks need before starting to establish the approval of competent authorities such as the It relies on special types of pickups that differ from each other in terms of the transmitted wave intensity and the angle of transmission of the wave at special frequencies that can be limited to the range between 5.8-2.6 GHZ, these pickups have a wave transmission capacity of up to 20 dbi and have many types such as :
Omni – directional antenna
Sector – antenna
Parabolic – dish antenna
And you also need special transmitters of the type:
Rocket M2 or M5
Base Box
It can integrate wireless WIFI signal transmitters and receivers via LOCO - NANO stations over distances exceeding several kilometers.
Registration periods for the monitoring and data preservation system
It is necessary to specify the required recording period for recording devices and using hard disks that enable you to record all those events, the captured events are recorded on the monitors by compressing audio and video files to the AVI or H Extension.264 and in some types for the extension of MPECO and for each type a way to calculate the size of the hard drive to record the number of days required, which is mostly not less than a whole month, but it is possible to determine based on the monitoring conditions for each site, DCS Egypt offers its customers a fast automatic computer to calculate the size of disks and storage
