Teradek Bolt 500 SDI / HDMI Video Transmitter and Two Receiver Set. Supports HD resolutions up to 1080p60 with near-zero latency, the Bolt 500 system can find its way into studio and field video productions. A single transmitter can support up to four receivers, so multiple monitors or recorders can receive the same signal. The Bolt XT satisfies the needs of the most discerning professionals, from powerful software tools and rock-solid performance to smart power options and backward compatibility. A key feature of the Bolt XT is its backward compatibility with any Bolt of the same range, Sidekick II / LT / XT, and 703 Bolt, giving users more flexibility building onto their existing systems or linking with others already on set. Unlike alternative wireless video systems, Bolt XT includes a unique AES 128 encryption algorithm to protect your video footage, ensuring that only authorized receivers can connect to your transmitter.​
