---

Smart Radio Systems are an authorised Hytera Dealer and PoC Service Provider for the leading South African PoC Mobile Network Operator, who operates the world leading Hytera HyTalk PoC platform. Our services include platform network access and a range of radio and bodyworn camera user devices.

We offer flexible outright purchase and rent-to-own finance options with 12, 24 and 36 x month fixed airtime contracts tailor-made to suit both your capital or operational expense budgets.

Hytera’s PoC range also showcases benefits on management systems, allowing them to be easier to use and reducing the need for high investment. This is because Hytera’s PoC management systems do not require a network to be established in order for them to operate effectively. Dynamically assigning resources to maximise channel capacity, the Hytera PoC systems support a rich variety of voice and data services – including man down, lone worker monitoring and high speed emergency response coordination. Caller ID ensures central control teams can immediately identify every radio user, taking advantage of caller interrupt to break into radio traffic to send out priority transmissions.

The Hytera HyTalk PoC communication solution delivers various services, including instant the voice and video call, unified dispatch, and multimedia data communication. Users can install the Hytera HyTalk client on smartphones, professional radios, multiple-mode advanced radios, or body worn cameras (BWCs) to access the Hytera HyTalk services through the public network (3G or 4G) or WLAN network to help communicate for mission critical anywhere.

Hytera Hytalk/Hytera Hytalk Pro PoC solution provides nationwide group calling from one or more dispatchers with pre-programmed or dynamic call groups. Quickly build dynamic groups with a simple list selection or by selecting an area on the dispatch map.

Hytera Hytalk

 can track multiple user locations and travel routes with job site time stamps to manage and dispatch remote workers. Dispatchers can draw geofences on the map to define boundaries for territories and service areas. Alarms can be generated when users enter or leave a geofenced area.

View and share multiple videos from remote workers using Hytera PNC550/PDC550 PoC radios and running the Hytera Hytalk Android app. Hytera Hytalk Dispatch can also save videos and stream to all users in the field.

Voice calls that meet various dispatching operational needs including: private call, group call and all call. Through the dispatching channels the system can receive all types of calls as well as trigger any type of call through a user-friendly and easy-to-operate interface.

All incoming/outgoing calls will be recorded and stored on the dispatch system server. Users can retrieve recorded voice calls and play them back at any time so that important conversations are not missed. All recorded voice calls can be searched via time of call, caller ID or called ID.

The dispatcher can perform various functions to terminals displayed on the map including calls, presence check, call alert, text messages and remote monitor. The current map interface can be saved so that when the client logs into the system again, the GPS can automatically open the previously saved map interface.

By un-muting the microphone of a radio the Hytera Smart Dispatch System will be able to monitor voice activities remotely without the PTT button having to be pressed. This can be useful in emergency situations when the control centre needs to listen to remote voice activities without the need for the radio PTT to be pressed.

This feature is only available for radio subscribers which are fitted with GPS. Each radio subscriber is able to obtain its location coordinate information from this built-in GPS module. The Hytera Hytalk Dispatch System can retrieve the location information of any radio either by requesting on demand the current position of the radio or by sending a Start Tracking Command, setting up a radio to update the location information from the radio to the dispatcher periodically with a configurable time interval.

The location of any radio can be tracked in real time. Users have the option to display the location route on the map. The tracking interval depends on the location update interval configured in each radio. The total number of location tracking activities that can be activated at one time will depend on the mapping system and limitations of system resources.

All location information of radios will be kept in the systems database for later retrieval and history location checking. Users are allowed to query history location information of a radio as well as playing back the location route of a radio within a specified time interval.

Dispatch users can define regions on the map as working or restricted areas for a predefined set of radios. This can also be enabled in each region. Once the geofencing rule is infringed (based on whether the area is a working or restricted one) by any of the predefined set of radios, a geofencing alarm will be activated in the control centre and optionally a message will be sent to the subscriber unit.

Dispatchers are able to send and receive PoC standard text messages. A text message can be sent to a radio or a group message can be sent to a group of radios identified by group ID. A chat-based GUI is used to send and receive text messages. All incoming and outgoing text messages are stored in the database for later retrieval. A text message can be sent automatically at a preset time, e.g, 1 day, 1 week, 1 month, etc.

When an emergency is activated by a subscriber radio, the Hytera HyTalk Dispatch System will trigger an alarm. Optionally, the location information of the radio that triggers the emergency will be shown on the map depending on the validity of the location information of the radio at the time the emergency is triggered. When speed alarm is enabled, alarm messages will be dispatched to radios that exceed the over-speed alarm limit. 

When the radio is powered on/off it will send a status report to the dispatcher. They will also be able to check the status of any radio with a status query command. This allows the dispatcher to monitor the status of all the radios in the system. 

The Hytera HyTalk System can generate various types of reports. Examples include, calling report, radio status report and location tracking report.
