Teradek Wireless Video for Film Sets: Bolt 7, Bolt 6 LT and Ace

A wireless video system has one job on a film set: put the camera’s picture on a monitor somewhere else, at the same moment the camera sees it. When it works, the director watches the take, the focus puller judges focus on a monitor, and the client sits at video village without a cable run. This guide explains Teradek wireless video in plain terms, compares the current zero-delay range, and lists what to ask before you commit to a kit.

Everything below about models and specs comes from Teradek’s own product and FAQ pages, read on 11 October 2026. Check the live pages before you finalise a purchase.

What a transmitter and receiver actually do

The transmitter (TX) mounts on or near the camera. It takes the camera’s video output over SDI, HDMI or, on some models, USB-C, and sends it out as a radio signal. The receiver (RX) picks that signal up and outputs it to a monitor, a recorder or a distribution rack. That is the whole idea. The difference between systems is how fast, how far, how clean and how many receivers you can feed.

Teradek calls its Bolt and Ace families “zero-delay”. Its pages say the performance starts with RF transmission, which removes the latency of Wi-Fi based workflows. The Ace Micro TX page goes further and states video with less than 1 millisecond of latency, over 70 times less latency than Wi-Fi based solutions. That is Teradek’s wording, and we are not adding any measurement of our own. For a focus puller, the practical meaning is simple: you pull on the wireless image and the image does not trail your hand.

Each person cares about something different. The director wants a stable image with no dropouts mid take. The DP wants accurate colour. The focus puller wants no visible lag and a receiver that mounts neatly. The client wants a reliable view, often on a tablet.

The current Teradek zero-delay lineup

On 11 October 2026 Teradek’s menu listed five products under Zero-Delay Wireless Video: Bolt 7, Bolt 6 LT, Bolt Mobile RX, Ace 750 and Ace Micro TX. Here is what each one is for. The brand overview sits on our Teradek India page.

Bolt 7

Bolt 7 is the top of the range. Teradek describes it as the same Bolt 6GHz zero-delay video, plus a separate dedicated channel for data. That data channel is a new 900MHz radio. Teradek’s FAQ explains that it works as a wireless Ethernet and USB cable replacement, enabling wireless camera control, live colour management and telemetry without a Wi-Fi network. It comes in 750, 1500 and MAX versions, with published ranges of up to 750 ft, up to 1500 ft and up to 5,000 ft. Other published points: a 2 inch full colour OLED display, direct wired pairing, USB-C DP-Alt mode on select cameras and iPhone, and a transmitter Teradek says is 20% smaller than the Bolt 6 XT.

One limit matters for mixed kits. Teradek’s FAQ says the 900MHz radio only works when both the transmitter and the receiver are Bolt 7. A Bolt 7 transmitter with a Bolt 6 receiver will carry video, but not the data channel.

Bolt 6 LT

Bolt 6 LT is the lightweight Bolt 6, with internal antennas, a compact aluminium body and 6GHz support. Teradek’s page lists 750, 1500 and MAX versions, with the MAX listed at up to 10,000 ft. Teradek’s own FAQ compares it with Bolt 7: Bolt 7 adds the dual radio system, the display, quick swap battery plates and DP-Alt mode on top of the same 6GHz foundation.

Bolt Mobile RX

Bolt Mobile RX is a receiver for iPad and iPhone. You connect it, open the Teradek TV app and monitor, with no Wi-Fi setup. Teradek lists 750 ft and 1,500 ft versions and says it receives video up to 4Kp30 from Bolt 4K, Bolt 6 or Ace transmitters. It suits a client or producer who wants a view on a tablet. On the day we read the page, Teradek marked it “Coming Soon”, so confirm availability before you plan a shoot around it.

Ace 750

Ace 750 is the HDMI entry point to the same ecosystem. Teradek states it works with any camera that has an HDMI output, at up to 4Kp30, over a range of up to 750 ft (228 m). It pairs out of the box and selects its frequency automatically on 5GHz and 6GHz. Teradek says Ace 750 works with all Bolt 7, Bolt 6 and Bolt 4K devices, and that range is set by whichever device has the shorter range. It does not work with the older Ace 500.

Ace Micro TX

Ace Micro TX is Teradek’s smallest transmitter. It connects over a single USB-C cable and sends 4Kp30 uncompressed video at ranges of up to 500 ft (150 m) to as many as six receivers. Teradek lists support for DP Alt Mode cameras including the Blackmagic URSA Cine and PYXIS, and it also turns an iPhone into a wireless camera. It needs external USB power. It is a transmitter only, so you need a Bolt or Ace receiver on the other end.

HDMI versus SDI, in set terms

Cinema cameras mostly offer SDI, while mirrorless bodies usually give you HDMI. The Bolt 7 and Bolt 6 LT pages publish both: SDI at 4:2:2 10 bit and HDMI at 4:4:4 RGB 8 bit. On Bolt 6 LT, Teradek publishes the maximum SDI resolution as 1920×1080 and HDMI as 4096x2160p60, so do not assume the SDI output matches the HDMI one. Ace 750 takes HDMI only, and Ace Micro TX takes USB-C. Match the connection to the camera you actually shoot with, then check the receiver’s outputs against your monitors.

How many receivers can you feed?

Teradek’s zero-delay page says each transmitter can share identical 4K video with up to six receivers, or unlimited receivers in Broadcast Mode, which it states is only available on MAX receivers. Before you buy, count the screens on your last three jobs, not the screens you hope to have.

6GHz and 5GHz in plain words

Wireless video travels on radio channels, and crowded channels cause interference. Teradek says Bolt 6 added 12 new 6GHz channels to the existing 5GHz options, which doubles the number of channels you can choose from. Bolt 7 carries both 5GHz and 6GHz bands as standard. An optional Advanced Spectrum License, needed on each transmitter and each receiver, adds licensed bands and 5MHz channel tuning. Teradek states its products meet FCC and CE requirements. We have not found any Teradek statement about Indian regulation on the pages we read, so treat India regulatory status as a buyer question and confirm it with us before you order.

Compatibility and older models

Bolt 4K Deluxe kits show as sold out on Teradek’s own product pages, which point buyers to the latest Bolt generation. The Bolt 4K hardware itself still talks to the new gear: Teradek’s FAQ says Bolt 7 is backward compatible with Bolt 4K, Bolt 6 and current Ace models, with the note that 6GHz is not available on Bolt 4K.

Older Bolt 500, 1000 and 3000 units are a different story. Teradek’s Bolt 7 FAQ says Bolt 7 is not compatible with those older BB2 Bolts, and the Bolt 6 FAQ says the same for legacy BB2 products. If you own an older kit, plan to replace both ends, not one.

Typical rigs

• Commercial or feature shoot, cinema camera: a Bolt 7 or Bolt 6 LT transmitter on the camera, one receiver at the director’s monitor, and a second at the focus puller’s monitor.
• Mirrorless run and gun: an Ace 750 pair from the camera’s HDMI port, or an Ace Micro TX on a USB-C camera.
• Client on a tablet: a Bolt Mobile RX once it is available.
• Monitor with the receiver built in: Teradek says SmallHD monitors are available with integrated Bolt 6 transmitters or receivers. See our SmallHD range for the monitor side.

What to ask before buying

• Which output does my camera give: SDI, HDMI or USB-C?
• What is the longest real distance between transmitter and receiver on my typical set?
• How many receivers will run at once, and do I need Broadcast Mode?
• Do I need wireless camera control or telemetry, which means Bolt 7 at both ends?
• Do I already own older Bolt or Ace units, and are they BB3 generation?
• What is the India regulatory status for the 5GHz and 6GHz bands on this model?

Frequently asked questions

What does zero-delay mean for wireless video?

Teradek uses zero-delay for its Bolt and Ace radios, which transmit over RF instead of Wi-Fi. Teradek's Ace Micro TX page states less than 1 millisecond of latency, over 70 times less than Wi-Fi based solutions. We quote that as Teradek's own claim.

Can a Bolt 7 transmitter work with a Bolt 6 receiver?

Yes for video. Teradek says Bolt 7 is backward compatible with Bolt 6, Bolt 4K and current Ace models. The 900MHz data radio only works when both the transmitter and receiver are Bolt 7.

Do old Bolt 500, 1000 and 3000 units work with Bolt 6 or Bolt 7?

No. Teradek's Bolt 7 and Bolt 6 FAQs say the older BB2 generation, including Bolt 500, 1000 and 3000, is not compatible with the newer systems.

How many receivers can one transmitter feed?

Teradek states up to six receivers per transmitter, or unlimited in Broadcast Mode with MAX receivers. Bolt Mobile RX is also listed at up to six per transmitter.

Is HDMI or SDI better for a wireless video system?

Neither is better. Use the output your camera actually has. Bolt 7 and Bolt 6 LT publish both, Ace 750 uses HDMI, and Ace Micro TX uses USB-C. Check the maximum resolution for each connection on Teradek's page.

Is Teradek wireless video legal to use in India?

Teradek states FCC and CE compliance. We did not find an Indian regulatory statement on the pages we read, so confirm the India status of the 5GHz and 6GHz bands for your chosen model before ordering.
