Teradek Serv streams live video from the camera directly to mobile devices, allowing the director and script supervisor to monitor the camera image on a tablet or smartphone.
Technical Details
The Serv weighs 95 grams and measures 89×54×21 mm with a power consumption of 4.5 watts via Sony NP-F batteries or DC input (7-17V). Transmission is via H.264 encoding with bitrates between 0.2-20 Mbps, with a range of 30-100 meters depending on the environment. The device supports up to 10 simultaneous clients via the proprietary "Teradek Serv Pro" app for iOS and Android. Three model variants exist: Serv Micro (HDMI input), Serv 4K (UHD support), and Serv Pro (enhanced encryption and user management).
History & Development
Teradek introduced the first Serv model in 2015 in response to the growing demand for cost-effective wireless video solutions. The California-based manufacturer was reacting to the dominance of expensive systems like their own Bolt series (starting from 3000 Euros). In 2018, the Serv Pro followed with improved encryption, and the 4K variant in 2020. The development aimed to make professional wireless video functions accessible for budget productions and corporate video.
Practical Use in Film
Documentary filmmakers use the Serv for discreet director monitoring, as cables are eliminated and smartphones serve as unobtrusive monitors. For "The Florida Project" (2017), cinematographer Alexis Zabe used a Serv system for spontaneous handheld shots with child actors, with director Sean Baker maintaining image control via an iPhone. Corporate productions appreciate the client functionality: up to 10 people can follow the live image simultaneously. However, the limited range and H.264 compression make the system unsuitable for demanding color grading monitoring.
Comparison & Alternatives
Compared to Teradek's own Bolt system, the Serv offers significantly lower latency performance (100ms vs. <1ms) but costs only a tenth (300 vs. 3000 Euros). SmallHD Focus Pro or Hollyland Mars systems compete directly, with the Serv scoring points through its multi-client capability. For critical focus pulling, a dedicated wireless monitor like the SmallRig RC 60B remains superior. The Serv is primarily suitable for director monitoring and playback functions, while professional camera assistance requires more precise systems.
