Smart City Migration to NG911 Relies on Cloud-Based Communication
Overview
Public safety communications are transitioning to IP-based Next Generation 911 (NG911) as a replacement for traditional, analog 911 communications. Sealevel partners with a proven global leader that is at the forefront of this digital transformation. Their NG911 solutions including call routing, crisis management software, and tactical communications are deployed in smart cities worldwide.
The company’s primary NG911 communications platform is cloud-based to enable the quick exchange of information between operators across call centers, reducing emergency response times. In accordance with NG911 goals, the platform enables the transfer of texts, images, and videos in addition to voice calls. As part of the system, they needed an external relay module to operate the light tower for each operator terminal to signify an active or incoming call. They also specified a need to communicate to the hardware via their cloud-based software application as opposed to native software drivers.
In accordance with NG911 goals, the platform enables the transfer of texts, images, and videos in addition to voice calls.
The Solution
To meet the requirements for Form C relays, USB connectivity, and Windows 10 compatibility, Sealevel specified the SeaDAC Lite 8115 USB to Form C Digital Interface. The 8115 allows users to control and monitor up to four Form C relay outputs via USB with status LEDs for I/O activity. For simplified field wiring, an added benefit for the many installations, the 8115 has removable terminal blocks. To further guarantee reliable communications, the 8115 features a Sealevel SeaLATCH locking USB port to prevent accidental cable disconnection.
Natively, the SeaDAC Lite 8115 USB to Form C Digital Interface includes SeaMAX software drivers and utilities for operation and integration via the SeaMAX API. However, as the customer requested the ability to communicate to the hardware via a web interface, Sealevel’s application engineers recommend WebUSB and WebSerial APIs. These APIs enable communication directly from a web browser through low-level commands.
120 of the 8115 interfaces are actively deployed in this initial call center upfit with future installations planned to integrate the next generation of 911 technology for smart cities around the world.
