Access nodes of the NSBox-LTE series use 4G / LTE wireless communication channel as uplink. In video surveillance networks, guaranteed bandwidth is required to transmit traffic from cameras in real time. The amount of information transmitted is very large. This is not a barrier to fiber optic data transmission lines, but can be a problem when using communication channels provided by cellular operators. To avoid the difficulties associated with transferring large amounts of data in real time, a compact video recorder (NVR) should be added to the NSBox-LTE access nodes, which acts as intermediate storage or buffer for video recordings.
 Accordingly, there is no need for round-the-clock video transmission in real time. Video recordings can be transferred from the NVR upon request. Naturally, the ability to access video cameras in real time remains, and the operator can obtain an image from any video camera connected to the access node.
  As models for the NSBox-LTE application, you can use any standard or customized NSBox Access Node models by adding a wireless 4G LTE router and NVR to the configuration, if necessary. The optimal choice can be compact special models NSBox-121 | NSBox-122 without ODF (Fiber Optic distribution Frame), in which there are 3-port switches with support for two or one PoE port with a capacity of 30W or 60W.
