What is HDZero Digital FPV System (Formerly Shark Byte)

by Oscar
Hdzero Logo

HDZero is a new digital FPV system, a step up from the traditional analog FPV system. HDZero offers higher definition video feed and is less prone to interference. In this article we will talk about what makes HDZero so popular, its products, and how it compares to DJI’s FPV system.

Shark Byte Becomes HDZero

HDZero digital FPV system was developed by Divimath, Fatshark pushed the technology to the FPV market and and rebranded it as “Shark Byte” (the earlier iteration was called “Byte Frost“). Around the end of 2021, HDZero transitioned from being the supplier and manufacturer of Shark Byte to providing products directly to retailers and customer supports, and they started using the name HDZero on its products. Meanwhile, Fatshark announced that Divimath will take over support for the Shark Byte system.

DJI vs. HDZero

Currently there are three major digital FPV systems: DJI’s digital FPV system, Walksnail Avatar and HDZero. We also know that Orqa is working on their own digital FPV system, but there’s no confirmed timeline yet on the release.

Let’s talk about how HDZero compares to DJI’s FPV system as of today, since DJI is the most popular digital FPV system currently.

Popularity and Development

DJI’s system was released in 2019, it has been around for much longer therefore it’s more widely adapted than HDZero today by comparing the size and activity of their respective user groups on Facebook .

However, being the new kid on the block, HDZero appears to be more willing to listen to its users and keeps pushing out new features that the community asks for. It can take literally forever for DJI to fix some small bugs, let alone new features.

Image Quality

HDZero’s video resolution is 1280x720p, same as DJI. The image quality from both systems look impressive compared to traditional analog system. However, DJI has better image quality than HDZero. It’s not better in all situations, but on average DJI is better.

Here’s a sample footage from the VRX recording (what you see in the goggles when flying):

However, the DJI video feed tends to just freeze when you lose video signal instead of gradually becoming worse like analog. The image of HDZero gets “blocky” as signal degrades, it might not look pretty but it gives the pilot a warning of how signal strength changes.


DJI handles multi-pathing interference better than HDZero (for example when flying in bando and underground carpark). However, DJI’s delay changes with signal quality, the variable latency makes it harder to control and unreliable in some situations.

While that’s usually not a problem for cruising and freestyle, HDZero has become very popular among FPV racers because of its consistent latency regardless signal strength or distance.

The other consideration is signal interference handling. Although HDZero handles interference better than analog, it still cannot match the performance of DJI’s FPV system in these noisy environments.


If you are new to the hobby, both systems cost about the same if you are buying everything from scratch:


  • FPV Goggles ($570)
  • Vista or Air Unit with original camera combo ($165-$200)
  • Total ($735-$770)

HDZero with analog goggles:

  • Analog Goggles ($210-$550)
  • Video Receiver ($240)
  • Video Transmitter ($50-$100)
  • Camera ($50)
  • Antennas ($50-$100)
  • Total ($600-$950)

HDZero with HDZero FPV goggles:

  • HDZero FPV Goggles ($600)
  • Video Transmitter ($50-$100)
  • Camera ($50)
  • Antennas ($50-$100)
  • Total ($750-$850)

On average, both systems cost about the same, but if you already own a pair of FPV Goggles with HDMI input that’s compatible with HDZero, you would be saving a considerable amount of money (for example, the Skyzone SKY04X, Orqa FPV.ONE Pilot or the Fatshark HDO2). The HDZero video receiver can used with most FPV goggles with HDMI input (check compatibility before purchasing).

With the DJI FPV system, you would have to get the DJI FPV Goggles to use it.

Apart from the goggles, the costs of the VTX and cameras are similar between the two systems.

Betaflight OSD Support

DJI supports some of the OSD elements in Betaflight, but not all of them, for example Link Quality, which has been an ongoing request for at least a couple of years now and I don’t see full OSD support coming any time soon to be honest. On the other hand, HDZero supports Betaflight OSD fully just like analogue system.

Hardware Options

When it comes to VTX, DJI only has two and they are both pretty big and heavy for micro drones. There’s no new VTX expected anytime soon that supports the current system. However, HDZero is constantly releasing new hardware, and there will be options for aircraft of all sizes and voltage requirements.

When it comes to cameras, both systems support third party cameras, but since HDZero is relatively new, there are currently more camera options for the DJI system than HDZero, but that is likely to change in the future as HDZero’s popularity increases.

User Experience

While HDZero is evolving rapidly, it still feels slightly more complicated to setup and use than other major digital FPV systems.

Open Source

The owner of Divimath announced on 24th April 2022 (source) that some of the software and hardware of HDZero will be open source. Hopefully this allows other companies to release their own compatible hardware for the HDZero system!

A List of HDZero Hardware

To use HDZero, you will need the following parts, which can be bought separately:

  1. Video Receiver (VRX) or HDZero-compatible goggles
  2. Video Transmitter (VTX)
  3. Camera
  4. MIPI Cable (for connecting the camera and VTX)

Let’s talk about all the HDZero hardware and specs.

HDZero Video Receivers

Apart from the Shark Byte VRX, there’s currently only one VRX module under HDZero’s name.

HDZero VRX Receiver Module

Hdzero Vrx Front

Product Pages:

This is the latest video receiver from HDZero, expected to be available in May 2022.

See my review here for a more detailed overview of the HDZero VRX.

Hdzero Vrx Fpv Goggles Mount Orqa Antenna

The HDZero video receiver module is designed to be mounted on the front of your FPV Goggles. It supports most FPV Goggles with HDMI input, though it’s optimized for the shape of Fatshark FPV Goggles. For other goggles you might need to get creative how you mount it (might require 3D printed adapter for example).

There are four SMA antenna connectors, and you should choose the right antennas for the job. When racing or just flying around the house, all omni antennas would work well. When flying outdoor and long range, using a patch antenna like the TrueRC X-Air MK II along with a couple of onmi would be an excellent choice.

The real time clock (RTC) automatically timestamps your DVR recordings to make it easier to review footage.

ExpressLRS Backpack expansion plug makes it easy to switch channel, output power and other features from your radio.

Ambient audio recording allows you to capture the sound around the pilot, such as lap times callouts and pilot commentary.

Shark Byte RX5.1

The original video receiver module for Shark Byte but also compatible with HDZero gear.

Product Page: Discontinued

The Shark Byte receiver module (aka RX5.1)  is an attachable module to Fatshark FPV Goggles. It’s weighs 80 grams, measures 105 x 21 x 39 mm.

It has two built-in patch antennas, and two SMA antenna connectors for two additional antennas (not supplied). Since the DVR in the goggles cannot record digital video, the RX5.1 has its own DVR.


Although both DJI FPV system and HDZero use MIPI between the camera and VTX, the MIPI connectors are actually different sizes in the two system and not interchangeable. Make sure you get the compatible cable for HDZero.

Other HDZero Accessories

MIPI Cable

Beware that neither the FPV camera nor the VTX comes with a MIPI cable, the ribbon cable that connects the camera to the VTX! You have to purchase this cable separately.

Hdzero Fpv Camera Vtx Ribbon Cable Mipi

Product Page:

It comes in different length so make sure you measure the length you need before purchasing. Lengths available are: 4cm 8cm, 12cm, 25cm. Note that the DJI MIPI cable doesn’t work with HDZero gear because DJI don’t use standard size MIPI connectors.

Get the longer cable! It’s better be too long than not long enough! I learnt my lesson the hard way. 12cm should be ok for most 5″ frames, but for some with long body it might not if you are mounting the VTX at the very back. Double check.

The receiver HDZero VRX can transmit image 1080p30p to the monitor with a good resolution?
What cameras to use?

Blufkip 20th May 2022 - 1:47 pm

Will the HDzero lite camera have an extreme fisheye effect since the cam and lens are so tiny?

Nick 18th May 2022 - 12:21 pm

Are you sure any goggles with HDMI inputs are supported by the receivers?

The reason for the question is that some goggles (such as Skyzone 02c) have HDMI but do not support the HDCP protection system. That means they may not work with some HDMI sources that expect it. I’m sure I have read that 02c goggles do not work with the Shark Byte VRx. Therefore that might apply to some other goggles as well.

Oscar 18th May 2022 - 12:42 pm

The Skyzone 02C does work, but just not plug and play, direction connection doesn’t work, and you need a converter (splitter) for it to work. Skyzone acknowledged the incompatibility and they fixed it in newer goggles after that.

Lemon 29th July 2022 - 2:49 pm

So the newer O2C and O2O goggles work plug and play ?

bvonbla 17th May 2022 - 7:57 am

It runs Linux! That’ll be a modders paradise!

rc dude fpv uk / mikey 16th May 2022 - 8:28 am

Great info, Thanks

Nikotttin 2nd May 2022 - 4:34 pm

Oscar, not all goggles with HDMI input work with Shark Byte (don’t know for the newest HDzero). My trusty sky02x would not work. I could however get the VRX to work on a TV and other monitors. Neither fatshark nor skyzone helped. Fatshark said it was developed only for fatshark. Skyzone said there’s a HDCP issue. Fatshark said it’s not the case. After months of discussions, I got frustrated and I resold all my equipment.

Please change the sentence above:
« The HDZero video receiver can used with any FPV goggles with HDMI input. » and feel free to edit this response. If you need the emails from fatshark and Skyzone, just ask.
