Worldcast Systems - Radio & TV Broadcast Solutions


In an emergency, response time is critical. Police, fire-fighting, search and rescue services depend on fast and reliable audio and video communications. Our resilient mobile network access solution with award-winning SureStream technology is designed to meet the needs of public safety aviation professionals for surveillance and video transmission in emergency situations.

Two solutions are available: 

  • APT SureStreamer HELI
  • APT SureStreamer DRONE

This resilient, low latency solution enables high quality, simultaneous video streaming between mobile surveillance forces (helicopters, drones and vehicles), the Control and Command Centers, and the first responders.
On a low and constant latency of less than 0.5 sec. over 4G/4G+/5G networks (glass to glass) enables fast and efficient decision-making and action-taking, in real-time.



Ultra-low latency

Thanks to the TCP-free signal chain and the omission of channel bonding, the APT SureStreamer HELI and DRONE ensure the lowest latency achievable and significantly lower than traditional broadcast video codec solutions.


SureStream is a streaming technology based on diverse streaming, sending multiple copies of your video stream across different carriers. You benefit from high stability of the IP connection, even under difficult circumstances. 


Utilizing secure VPN encrypted links for all transmissions over the cellular network and the public Internet, end-to-end video is secure and safe from prying eyes.

Low operating costs

Your video content is distributed across affordable 4G/4G+/5G mobile internet links. Using the unique tool-sets and features incorporated within SureStream, the SureStreamer HELI and SureStreamer DRONE are compatible with any network with the use of standard SIM cards.


Helicopter Application

With the SureStreamer HELI our first responders can have multiple and simultaneous access to the ‘eye in the sky’ in real time.
The team on approach make critical split-second decisions without direction or communication form the pilot


SureStreamer Heli in Operation with a USA Sheriff Department

See how one Sheriff Department used the SureStreamer Heli to broadacst ULD (Ultra Low Delay) video from their onboard camera with augmented reality / digital mapping overlay. No requirement for any expensive ground infrastructure, SureStreamer Heli uses the award winning SureStream algorithm and existing cellular (4/5G) infrastructure to send seamless video from Air to Ground with seamless broadacst quality. The video is then relayed to remote command centres, on the ground operational positions, and first responders again in real time with ULD.
