Drones provide a mechanism for streaming compelling video that other methods cannot compete with either from an infrastructure or cost prospective.
Whether it is used in broadcasting for sports or other aerial views, or for public safety to monitor crowds or in other civil emergencies, often the footage is required in real-time to provide up-to-the-second footage of unfolding events from a unique position that is not available to people on the ground.
For broadcasting the footage can be so fascinating, for public safety it can be lifesaving. Either way, a reliable and cost-effective method for delivering real -time video footage is indispensable.
This is where the Soliton Zao-S can reign supreme.
Typically drones with an on-board camera provide a Wi-Fi link to a base station near-by. Recent testing has shown this works very well and from the download link it is then possible to connect the output of the Wi-Fi base station to a Zao or Zao-S and then live-stream over multiple “bonded” 4G telco mobile phone signals, via dongles, fitted with SIM cards. With the Zao-S, the video feed from the camera is encoded to H265 and streamed back to any internet connected server in the world that can decode back to the original video signal – all with very low latency typically two to three seconds later.
However given the small size of the Zao-S and its H265 capabilities, another option has recently become available and only available via Soliton.
Tiny HEVC encoder for your drone
The Zao-S is a light weight encoder that weighs only 400 grams including its own internal battery. It is possible to mount the Zao-S in the drone with an onboard camera, and from within the drone, it can live stream video to anywhere in the world. And this is high quality HD video that will not deteriorate as the drone moves further away, as other streaming systems suffer from. The Zao-s does not need necessarily need Wi-Fi or a base station.
This has the added advantage that the drone can travel much further distances without concerns for losing Wi-Fi, especially if the drone is on an automated pre-planned trajectory path that may go quite a few kilometres. Also given that it streams directly back to a command centre for example, the latency can be very low, typically between half and one second.
Long Distance Drone Travelling with video streaming
Drone video streaming has never been more reliable for the broadcaster or for public safety applications that includes police, fire departments and even for military applications where drones need to be flown long distances. The Zao-S can use multiple 3G or 4G LTE mobile cellular networks to stream video. In the event that one of the cellular signals disappears, the Zao-S will automatically compensate. It is designed for reliability. Also by using the latest H.265 HEVC compression algorithm, as oppose to the older H.264 encoding algorithm, it needs less bandwidth and less bitrate to maintain delivering good quality HD video.
By programming the Zao-S on the live streaming drone with a global IP address, it can stream to a control room anywhere very quickly with very low delay.
The Zao-S is very secure and can support full AES256 encryption making it ideal for many law enforcement, public safety and military applications where security is an issue.
For broadcasters, the video streaming drone simply provides beautiful content from any live event or music concert, reliably, quickly and cost effectively that can be broadcast as part of any live event programme and/or via social media using IP (RTMP) vide streaming.

Drones provide a logical cost efficient mobile live-streaming for emergency services. With drones you increase surveillance and indeed increase the periphery of vision in the sky with instantaneous broadcasting of footage to the control centre.
This drone activity could cover many roles in outdoor events from monitoring large environmental disasters such as flood control, through to finding or identifying pirates or refugee vessels.
The ease at which a wild fire can start and then rage out-of-control with wind being a major factor, makes them difficult to contain and ultimately extinguish. By live streaming from a drone, we can get an immediate real-time view of what is going on” says Dangerfield. “We use the Soliton Zao-S technology to live stream reliably over multiple 4G connections which has a very low latency.
With the increase of Artificial Intelligence and mapping accuracy over recent years, more companies are seriously considering taking logistics to a new level of sophistication. With the profitability of letter deliveries remaining low, most delivery companies are making the most of on-line purchases by focussing on parcel deliveries.
If the stumbling blocks to adoption in the past have been technology, these are improving daily too. Artificial Intelligence (AI), logistics, encrypted, remote guiding, tracking on GPS (for sabotage – stealing purposes) have all made significant progress in the the latter part of the 2010’s.
Each logistical operation would ideally use live streaming, which would ensure that the delivering party can see where the drones are real-time. Many would initially be piloted and therefore requiring live stream, to ensure buildings, electricity wires and other obstacles are avoided. Even pre-programmed GPS drones would benefit from live streaming, to ensure the safe delivery of products.
The way Soliton has deployed the H.265 hardware based encoder results in at least 50% more efficiency in bandwidth usage compared to traditional solutions. For example: a 3 Mbps Soliton H.265 stream provides the same video quality as a stream doing 6 Mbps in H.264. The 4G Bonding algorithm has also been improved dramatically compared to the traditional 4G bonding systems. The overall result is a much improved picture quality, even with less latency, which is typically under half a second. It is even possible to have 2 way communication between the camera team and the editorial people with minor delay via the ZAO.
With the reduced cost of high definition cameras, parcel deliveries can use HD cameras for each delivery. The 4G bonding system, ensures that live, encoded video transmissions would be distributed between multiple networks to the Milestone or HDView systems, This collectively adds another level of difficulty to an already complex system to hack.
