The A Block is the most important design entity of the network. 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 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 of video streams from all Encoders in the A Block. Additional storage is provided by 
SEB5000 storage expansion boxes.

Figure 1 shows the Endura components that comprise the A Block. The SEB5000 is shown directly connected to the NVR5100 using a patch 
cable. If multiple SEB5000s are required, you can use a dedicated, Pelco-approved gigabit Ethernet switch to expand the video storage of the 
NVR5100. For more information about connecting SEB5000s to the NVR5100, refer to 

 on page 26.

In a network, the logical area within which all devices can see each other’s broadcasts is referred to as a broadcast domain. Endura components 
generate multicast traffic, which in some cases can be treated like broadcast traffic, depending on the switch. For this reason, it is important to 
isolate these broadcasts and to create a separate broadcast domain for each Endura block on the network. The most efficient approach is to use 
VLANS to separate the broadcast domains (refer to Figure 2).
