The Teradek Bolt is a wireless transmitting system for HD video signals and its primary utility lies in configuring a convenient and efficient, on-set monitoring scheme, such as a video village. As many of you may know, the term “video village” derives from a common phenomenon on film sets, which is precipitated by a monitor’s ability to attract a sizable population of curious onlookers. This is where the Bolt comes in. Teradek’s Bolt can wirelessly transmit a 4:2:2, 1080/60p video signal up to 300 feet with no frame delay, which means that all of the noises and distractions inherent to a video village can be located a suitable distance from the action.

Bolt transmitters come in “unicast” and “multicast” varieties. The Bolt Pro is the multicast model, and it enables users to transmit to multiple receivers simultaneously, with secure AES 128 encryption. The Bolt Pro also features 3G-SDI connectivity with loop-through and an internal, rechargeable Li-ion battery with enough capacity for approximately 60 minutes of run time. Both the Bolt Pro and the Bolt (unicast) feature a 6-28 volt LEMO DC input for connecting an external power source.

Bolt transmitters are enclosed in a milled aluminum housing, and the Bolt receiver is housed in ABS plastic. In addition, a number of 1/4”-20 threaded holes provide several mounting points for attaching the transmitter or receiver to a support system. Despite its robust construction, the Bolt transmitter weights only 7 oz.

The Bolt receiver features dual 3G/HD/SD-SDI outputs for either a two-monitor configuration or one monitor plus a Teradek Cube or Brik. Compatibility with Brik and Cube encoders allows the Bolt to stream to an iOS device or a content-delivery network of your choice via HLS, ZiXi, RTMP, RTP, RTSP and MPEG-TS transport protocols. WSDI Pro technology enables the Bolt system to adjust frequency bands in real time, which allows the system to coexist with Wi-Fi and 5 GHz cordless phones.


The Teradek Bolt Pro Wireless 1080p60 SDI Monitoring Transmitter & Receiver set includes the Bolt Pro transmitter. The difference between Bolt Pro and non-Pro is that Bolt Pro has a looping SDI output, a 70 minute internal battery, and can connect to more than one receiver.

Wireless 1080p60 4:2:2
The Bolt Pro Transmitter and Receiver set can wirelessly transmit 1080p60 4:2:2 up to 300 ft with zero delay. 

1 TX to Multiple RX
A second and even more than two receivers can be added into the setup. One Bolt Pro transmitter can transmit full 1080p60 HD video to multiple receivers simultaneously. Bolt receivers have dual 3G-SDI outputs, which can connect to field monitors, switchers, and also Teradek Cube Encoders. 

WSDI Pro Connectivity
Bolt transmits uncompressed video using WSDI Pro, which provides a wireless range of up to 300 ft and can coexist with other wireless equipment by dynamically adjusting the frequency bands used in real time. Bolt Pro transmitters have loop-through SDI outputs that you can connect to local monitors or recorders. 

Internal Battery / P-Tap / Lemo DC for External Batteries 
The transmitter has an internal 70 minute battery and a P-tap input for connecting to camera batteries. An AC power supply is included for the receiver. The transmitter and receiver each also have a Lemo DC input for connecting external V-mount or Gold-mount batteries. 

Rugged Design
The transmitter has a milled aluminum body, and the receiver has an ABS plastic body. Both the transmitter and receiver have 1/4" mounting threads and can be attached right onto or next to the equipment you'll be using them with.
