How a dronestagram serves in rescue, patrol application?

Drone, as an auxiliary and high profiled tool, catches people’s eyes as the development and exploration of 5G technology in civil industry. it is widely used in disaster rescue, surveillance patrol, electricity patrol, transportation surveillance, scenic spot aerial photography, film aerial photography, personal aerial photography etc. by equipping drone with a camera to take videos, DDMALL provides multiple solutions for transmitting drone video to ground for surveillance or live streaming.

● Low-latency transmission of drone aerial video

By choosing low-latency-transmission solution HEV-2K + HDD-20, it can realize AV low-latency(less than 86ms) transmission to large screen for display or surveillance.

1, Drone transmits video to its remote control by its own image transmitting technology.

2, Plug HDMI IN of HEV-2K into HDMI output interface of the remote control, to complete AV stream encoding, compression and transmission.

3, Connect HEV-2K and HDD-20 to the same LAN to conduct DDMALL’s unique low-latency AV transmission.

● Dronestagram video remote transmission

The main solution for remote transmission of drone aerial video is via RTMP live streaming. So a third-party live streaming server is required when people conduct living streaming via RTMP protocol on Internet resulting in high-latency transmission and high risk of data exposure. So it is not suitable for those have high requirements for real-time data and high confidential industry.

DDMALL solution HEV-4KW+HDD-20 can realize safely, reliable and low-latency remote transmission of drone aerial video.

1, Video taken by drone is transmitted to remote control via drone’s image transmitting technology.

2, Plug HDMI IN of HEV-4KW into HDMI OUT interface of remote control to process AV encoding, compression and transmission.

3, HEV-4KW joins Internet via router/portable router to process NAT port traversal via upnp and binding dynamic IP on Internet to domain via DDNS. The computer or decoder can build a link and conduct AV transmission on Internet via domains of encoder + WAN port.

4, HDD connect Internet via wired network and decode AV stream received and output to display equipment.

5, It is suggested to use SRT transmitting protocol for HEV-4KW+HDD-20 as SRT is a protocol based on UPD that it has low latency(about 120ms) and supports AES encryption to ensure the data safety.

● Dronestagram video multi-routes transmission

In some special industrial applications, Drone is always equipped with some other professional cameras to take videos to gain better quality aerial photography. In the meantime, to increase drone’s endurance by powering drone at base station. When the video taken by drone need be transmitted to both drone’s remote control screen and computer for surveillance, how to realize video’s multi-routes transmission

HEV-20W provides a solution for multi-routes transmission of drone aerial video. HEV-20W with size 110mm(L)*60mm(W)*22mm(H) and weight 96g, is very convenient to equip on drone. In the meantime, HEV-20W supports both wired and wireless transmission methods. It also has a HDMI local loop output function.

1, Plug HEV-20W HDMI IN into camera’s HDMI out interface to process video collection, encoding, compression and transmission.

2, Plug HEV-20W’s HDMI OUT into HDMI input interface of drone’s image transmitting system to transmit drone’s video to the drone’s ground control platform screen.

3, HEV-20W can join the ground computer’s network via wired or wireless (via portable router) connection. It then can transmit drone’s aerial video to ground computer for display via RTSP/UDP/SRT/HLS/RTMP protocol.
