Product Overview
The Teradek Prism Mobile 857 HEVC/AVC Video Encoder with Dual 4G LTE (V-Mount) is a professional portable video encoder designed for live streaming and broadcast contribution over bonded cellular networks. Supporting both H.265 HEVC and H.264 AVC encoding up to 4K, with dual integrated 4G LTE modems for bonded cellular streaming, and a V-Mount battery plate for extended field operation, the Prism Mobile 857 is purpose-built for ENG, live news, sports broadcasting, and remote contribution workflows where fixed internet infrastructure is unavailable.
Product Description
The Prism Mobile 857 V-Mount accepts 12G-SDI and HDMI 2.0 inputs and encodes video using H.265 HEVC or H.264 AVC at bitrates suitable for broadcast-quality streaming. The dual integrated 4G LTE modems bond two cellular connections simultaneously — maximizing available uplink bandwidth and providing failover redundancy when one carrier experiences congestion or signal loss. A 12G-SDI loop output passes signal through to local monitoring equipment while the encoder streams upstream.
The V-Mount battery plate enables hours of untethered field operation on standard professional V-mount batteries. Teradek Core cloud management provides remote monitoring, stream management, and encoder configuration from broadcast control rooms. The unit supports SRT, RTMP, and BGAN streaming protocols, integrating with a wide range of CDN and broadcast contribution platforms.
