Considering these units are essentially a plug and play wireless transmission, the Hollyland Pyro S packs in a decent range of features.
First and foremost, as previously mentioned, you have one transmitter that connects to your camera through HDMI or SDI (depending on your system) and can transmit that signal to four receivers, enabling the director, director of photography, and others to monitor exactly what’s going on from afar. When it comes to distance, it has a range of up to 400 m, so if you are filming an event and you’re unable to get to a camera, utilising one of these systems is a great way to keep an eye on what’s going on, especially with that low latency of 0.05 seconds.
In busy locations, interference can be a real issue, but here, the system utilises dual-band 2.4 GHz and 5 GHz, which should provide a good, strong signal. Also, helping to ensure the best possible transmission, the units feature auto frequency hopping, so if they sense any interference, they will quickly swap to another clearer channel for an uninterrupted feed.

One of the great features of the Pyro S is the multiple power options. You can either fit an NP-F battery, which should provide plenty of power, especially if you’re out and about on the move, or you can power it with a DC adapter so that you can feed it from the mains or a portable power station such as the DJI power banks . Unfortunately, there’s no USB power, and as these units operate at less than 11 watts, it’s something you’d think would have been included.
Another great feature is the UVC and RTMP streaming, which enables you to use these units for live streaming content directly to popular social networks.
When it comes to video transmission quality, these units are able to transmit at 4K 30fps for smooth video quality when monitoring your production. A standout feature of the Pyro S is that it’s compatible with all other products within the Pyro range. So, if you have a Pyro S, it will communicate with other Pyro S units, the Pyro 7, and the Pyro H, giving you plenty of flexibility in the field.
The unit essentially has two functions. Under the broadcast mode, when it’s activated, it is able to transmit to up to 4 other Pyro devices. When it’s deactivated, it can still transmit to up to 2 Pyro S units but will also transmit to up to 2 mobile devices. However, don’t expect the same range from a mobile device as you would with one of the Pyro units.
There are also two transmission options: Smooth mode and HD mode. Smooth mode drops the bitrate of the transmission to give you ultra-fast and smooth visuals, which is ideal for monitoring in most situations. In contrast, HD mode boosts the bitrate to 8 to 12 Mbps and is better if you need to record footage from the monitors.
Another feature that Hollyland has added to the Pyro S is the USB Video Class. This means that when plugged into a computer and utilising OBS software, you can transmit from your camera to the Pyro S transmitter, to a Pyro S receiver that’s plugged into a computer, and then stream to your favourite social media platform such as YouTube, Instagram, Facebook, or even TikTok.
While this is impressive, they’ve also taken things a little further. If you’ve got a 4G LTE Wi-Fi modem, you can plug that directly into the Pyro S. The Pyro S will then transmit to your mobile phone installed with the Hollyview app. From there, you can again transmit to your favourite social platform.
Essentially, the Hollyland Pyro S is packed with features, but at its heart, it’s easy to use. All you really need to do is plug it in and get going with filming, knowing that these other features are ready to use if and when you need them.
