HDZero is a pioneering digital FPV video system developed by Divimath, offering near-zero latency high-definition transmission for drone racing and freestyle pilots.
HDZero represents a significant evolution in FPV (First Person View) technology, delivering high-definition 720p 60fps video with the ultra-low, fixed latency required for competitive drone racing. Developed by Divimath, Inc., the HDZero system eliminates the variable lag found in other digital solutions, providing the locked-in feel of analog video with vastly superior image clarity.
The ecosystem supports standard 5.8GHz frequencies, allowing up to eight pilots to fly simultaneously without interference. HDZero offers a wide range of components including video transmitters (VTX), receivers (VRX), cameras, and goggles, often designed for seamless integration with popular flight controllers like Betaflight. By prioritizing speed and community-driven development, HDZero has become a top choice for FPV enthusiasts seeking performance and precision.

The latest firmware for VTX, VRX, and goggles can be found on the official HDZero Document page at www.hd-zero.com/document.
HDZero is designed for ultra-low, fixed latency (less than 1ms glass-to-glass), making it ideal for racing and freestyle where reaction time is critical. It behaves similarly to analog video but with HD clarity.
You can update firmware using the HDZero VTX Programmer tool connected to a PC via USB. Alternatively, some flight controllers support passthrough flashing. Always refer to the specific manual for your VTX model.
HDZero operates on standard 5.8GHz channels. While it can coexist with analog systems, pilots should ensure they are on non-overlapping channels to avoid interference, similar to managing multiple analog feeds.
HDZero typically covers items that are Dead on Arrival (DOA). Damages caused by crashes, mistreatment, or powering up without an antenna are generally not covered.
