Teradek claims the ranger is the world's first wireless solution that can transmit 4K HDR video streams with (almost) zero delay (

With Teradek's patented JSCC technology (Joint Source Channel Coding), the ranger transmits uncompressed 4K HDR video. At the same time, AES 256-bit encryption using the RSA 1024-bit key pairing secures the transmission immensely. In addition, the signal can be received by up to 6 receivers with only one transmitter, which underlines the multicast capability of the product.

Another user-friendly function is the Teradek Launchpad smartphone app, which is available in the App Store and on Google Play. With this phone app, the production team can set up wireless control functions, initialize device pairings, check interference across the channel, or consider other elements of the workflow such as the selection of the primary operating frequency.

This is of course an optional option as the user can still control the menu using the joystick navigation and the OLED display on the side of the product body. The other inputs, outputs, controls and connection options are clearly shown in the following illustration. Of course, a 12G-SDI input and a loop output form the heart and soul of the product. As usual, the V-Mount or Gold Mount battery on the back of the device, which supplies the entire camera with power, is usually also operated directly or indirectly with such transmission products. In this case, a 6-28 V DC connector with a 2-pin Lemo connector is available.

Differences between Teradek Bolt 4K and Teradek Ranger

Many filmmakers may know Teradek Bolt or Bolt 4K even better. You might also be wondering what the difference between your Teradek Bolt 4K MAX (with activated 12G-SDI and HDMI 2.0 (In / Out), DCI-4K resolution with 10 bit (4: 2: 2) at up to 60 fps unlimited receiver and the same transmission distance of 1,500 m line of sight) and the ranger.

Both products rely heavily on the same thing
