Zao - SH
Zao-SH – Ultra Low Latency Mobile Encoder
The Zao-SH is a small mobile encoder that can live stream video from a remote location back to any destination. But with an incredible glass-to-glass latency of only 35ms over LAN, or 65ms over 4G.

The Zao-SH is an H.265 HEVC encoder that can be used in a variety of video contribution scenarios from broadcast for news gathering to public safety, law enforcement and military application. It can be utilized to send an encrypted live stream from a broadcast or surveillance camera, drone, vehicle, body cam or helicopter.

The Zao-SH can send a fully encrypted live stream, but simultaneously a return data feed can be sent from the destination back to the Zao-S, for example to control a PTZ camera or to control a drone gimbal remotely.

The Zao-SH can live stream reliably over multiple bonded 4G SIM cards from different network providers, and /or can be utilized with a LAN connector.

At the receiving end, a Linux based software decoder will provide a video output of the live video. End to end latency starts at a remarkable 35ms.
