Sentra Push-to-Talk (PTT)

Nybsys Sentra is a robust, secure, easy-to-use real-time communications and tracking solution, that helps frontline teams stay connected with always-on communications.

  • The Sentra PTT app transforms a Smartphone into a next-generation walkie-talkie, and
  •  Sentra Dispatch and Config applications allow easy setup and dispatch operations.

Both are free and bundled with the Nybsys Malin Networking solutions, including Malin 4g/5g private wireless solutions. Sentra provides easy-bridging to L3Harris military-grade P25 and with business-critical DMR narrowband radio solutions from Nybsys or elsewhere.

Sentra Push-To-Talk App

Sentra connects your team instantly on private, secure voice communication channels. Sentra allows both hosted and private options – so you can connect to Nybsys hosted sentraptt.com platform or host your own Sentra PTT servers. Sentra Push-to-Talk and tracking features can be accessed on multiple platforms, including Android, iOS, web browsers, and even on Android Auto-supported cars. The Sentra App can be deployed to any device. It has been embedded into even IoT devices, such as vending machines and intercoms.

Sentra Dispatch

The NybSys Dispatch Console is a full-featured but lightweight web-based dispatch solution that simplifies daily radio dispatch operations, and allows organizations to rapidly respond to incidents, emergencies, and facility events. It allows tracking locations and statuses, thus helping decide when and where to dispatch response teams. And dispatchers can facilitate and coordinate team collaboration by bringing the right people in PTT voice groups.

Sentra Car Connect

The Sentra App connects a car audio and dashboard system if Android Auto or Apple CarPlay is enabled in the vehicle. The Sentra Car Connect offers uninterrupted communication while driving with a hands-free option. Channel lists are displayed in the car dashboard, and users can mute and unmute a channel. The Android Auto support will ensure hand-free conversation. No additional installation or license is needed.

The Sentra App, when installed on the phone and connected via car USB, the app will be loaded in the car. You can press and talk if you prefer on the phone while driving or enable the VAD feature. Car Connect feature is only limited to talking and message listening capacity. Only Sentra offers this feature that can replace a need for mobile devices installed in a car. A single app can be used as a portable or a mobile installed in the vehicle without physically installing anything.

Sentra Device

The Sentra 199 is a 3G / WiFi Android Radio, without display, offering basic communication operations. You can install apps from your computer to the radio via the USB port. The radio comes with Sentra PTT built-in with a push to talk button and channel selector. The device offers traditional walkie talkie features without any required license fees to regulators.

The device is automatically trunked and can be accessed from anywhere, any time. Sentra PTT offers channel selector and PTT button functions along with text to speech notification feature. The device comes with a panic button option. A man-down feature is also included which allows dispatchers to get notified if the device has a sudden fall from a certain height.

Sentra PTT Features

Instant Touch

With Sentra, you can connect your team with just a touch of a button. Use any mobile phone like a walkie-talkie that extends your corporate two-way radios. Or it could act just like an extension of your IP PABX or Cisco CUCM / Cisco UCCX. There’s no need for any delay dialing someone and find that person. The user will get the message live, or the message will automatically be recorded on his phone.

Talk Group or Individual

Sentra lets a user instantly contact an individual or a group under different channels using the push-to-talk service. Group call supports floor control and can set the priorities to talk or hold in a group conversation. Individual calls are just like calls between two parties. Land mobile radios can easily communicate as a group member and similarly, an individual can call the traditional walkie-talkie from anywhere.

Locations

Even if a person is not online or is active on another channel, with Sentra they do not miss out on any conversations. A backup of the entire group communication remains stored as history. We also offer historical reports and analysis with the Sentra Dispatch.

Access Anywhere

The Sentra PTT usage is not limited to any specific network, device, or technology. It is a ready-to-go feature with very high security and reliability. So, the walkie-talkie on the phone can be accessed anywhere. Messages will be received from any network, any device, and anywhere in the world.

High Security

One of the most significant advantages of the app is that it is highly secure. All keys are exchanged using certificates. Users can install a custom certificate with the level of encryption they are looking for.

Photo Sharing

A picture tells a thousand words. You can share photos like Instagram or Snapchat in the Sentra app. Group photos and videos can be shared with the dispatcher, making it easy to explain the situation without saying a word.

Alerts

Alerts are a critical component of mission-critical communications. It can be a man-down alert or an auto-generated alert from an IoT sensor. e.g., a fire alarm from a smoke sensor or an intruder alarm from a PIR sensor. An alarm can also be generated from a video camera. NybSys Survello platform generates suspicious object detection or anomaly detection alarms which can be automatically routed to the Sentra platform.

Radio Integration

Any traditional radio network can be integrated using our LMR gateway device. Once connected, each radio channel appears as a Sentra User in the group or individual call. This way a regular Sentra user can push and talk to any radio network natively from anywhere. Currently, we support analog, DMR, P25, and NXDN land mobile radio networks with the Sentra Gateway system

Sentra PTT Benefits

Sentra PTT addresses the major challenges in mission-critical communications:

Complexity, Manageability
and Security:

Managing multiple devices, including LMR radios along with cell-phone, wearable, etc for mission-critical communications is increasingly challenging, not only for end-users but also for departments trying to manage and secure communications

Silo’d Outdated
Communications:

Workers using older LMR radios for secure workplace communications are also using over-the-top non-integrated Apps like Messenger, WhatsApp, etc with their private smart-phones. The Talk Groups on LMR and the much more dynamic voice chat groups do not necessarily overlap and create communication gaps.

Reliability, Timeliness
and Cost:

Mission-critical voice needs to be delivered immediately and reliably. Free over-the-top Apps is not designed for that, but LMR is too expensive to offer to everyone.

Sentra turns a Smartphone into a next-generation walkie-talkie and extends several advanced benefits.

  • Any company with field users who need to communicate with each other or need a dispatcher-led communications solution will benefit from using Sentra.

  • Other Companies that can benefit include those who want to connect different radio systems or those who want to expand or migrate away from their narrowband land-mobile-radio coverage by having LTE or 5G coverage.

  • Other than day-to-day operational communications, Sentra is perfect for seamless Incident Response across various usages, including factories, mining, hospitals, governments, public safety, first responders, and transportation workers.

  • If you use Nybsys Malin 4G or 5G solutions, you can try out the integrated and bundled Sentra PTT solution.
