The Zao-X is a hardware transmitter for cellular that can stream fully encrypted live video. Simultaneously, a return data feed can be sent back from the operations center, enabling various operations such as controlling a 4G-enabled surveillance PTZ or broadcast camera, or remote control of a device that relies on a real-time operator such as a robot, drone or vehicle.
The Zao-X can reliably live stream over multiple bonded 4G and 5G SIM cards from different network providers. Additionally, it can support Wi-Fi and LAN connectivity.
At the receiving end, a Windows, Linux, or cloud based software decoder will provide a video output of the live video. End to end latency starts at a remarkable 0,04s.
Shoot
The period from when the light enters the lens of the camera until video data is on the output of the SDI/HDMI terminal on the camera
Capture
The period from capturing video data from SDI/HDMI and performing color space conversion until it is input to the encoder
Encode
The encoding (compression) time
Transfer
The period in which compressed data is extracted from the encoder and divided into communication packets for multilink transmission/reception. Includes time for error correction and packet sorting between each connection
Transfer
The period in which compressed data is extracted from the encoder and divided into communication packets for multilink transmission/reception. Includes time for error correction and packet sorting between each connection
Decode
The decoding (uncompression) time
AV Sync
The time until adjusting audio and video timing and outputting to SDI/HDMI
Display
The period from SDI/HDMI output of the receiver to display the video on monitor (monitor-dependent part)
