ENDURA C BLOCK
Figure 7 illustrates how the A, B, Core, and C Blocks concept is implemented to form a complete Endura network. The Endura network is scaled
by replicating the A and B Blocks to accommodate the video input and performance requirements for the network application.

Table H lists the Endura network blocks and summarizes the functionality for which each block is responsible.

Entity Function Network Devices
A Block The A Block is functionally responsible for encoding, recording, and storage of the video streams
entering the Endura network (both live and playback video).
The A Block is summarized as follows:
• Each A Block can support up to 48 NET5301T encoders and one NVR5100.
• Each A Block is assigned to a specific VLAN.
• The number of A Blocks is unlimited.
• Each A Block has only one NVR5100 for recording all NET5301T video streams: video is
recorded on the NVR5100 and stored on the SEB5000.

B Block The B Block is functionally responsible for decoding and displaying the video streams, as well as
providing the control and configuration of the Endura networking components.
The B Block is summarized as follows:
• Based on permissions, operators can view and control any camera on entire system.
• Each Block is assigned to a specific VLAN.
• The B Block can be replicated any number of times (limited only by network capacity).
