10 Best Video Transmission Systems
for June 2023

Choosing the best wireless video transmitter is no easy task, but thanks to HEVO, the Cosmo C1 from Hollyland is a winner. It's reliable, easy to set up and use, and is light-years ahead of other wireless video systems. The Cosmo C1 is easy to set up, and after we plugged it in, it automatically connected our camera, monitor, and switcher to our Mac. (The Cosmo C1 also supports HDMI and SDI input, but we only tested it with HDMI and SDI output.) We were pleasantly surprised by the Cosmo C1's video quality -- the 1,000ft LOS range, 40ms latency, and 1080P60 video recording are all impressive. The Cosmo C1 is also easy to set up in auto-switching mode; in manual mode, it allows you to switch between different wireless transmitters in seconds. The Cosmo C1 also has a wide enough range to work with multiple cameras, monitors, and switchers. The Cosmo C1's video transmission range is about double that of our previous top pick, the Teradek Bolt Pro, and it's 40ms latency is just 1ms slower. The Cosmo C1's battery life is also impressive -- it can last for up to 3 hours on a single charge.

The Mars 400S Pro from Hollyland is a wireless transmission system for shooting video with 4K cameras. It improves upon its predecessor, the Mars 400, by dropping the price, adding 4K resolution, and adding SDI input (for 4K cameras that don't have HDMI). The Mars 400S Pro's video quality is competitive with its predecessor, and its latency is extremely low, making it well-suited for real-time streaming. It has the same range (400 feet) and same power options, and it also has low light sensitivity, allowing it to transmit video in dimly lit conditions. It has the same unique features as the Mars 400, including audio monitoring, an IR remote control, and auto-frequency management. The downside is that its video quality isn't quite as good as that of the Mars 200, and it has the same audio monitoring issues. The Mars 400S Pro also costs more than the Mars 200, and it lacks an audio delay feature, which the Mars 200 has. The Mars 400S Pro also doesn't have SDI input, which the Mars 200 has, and it also has slightly lower video quality. Overall, the Mars 400S Pro is a good choice for shoots with long cables, but its video quality isn't as good as that of other 4K wireless transmission systems.

The Mars 400S PRO is an affordable, professional-quality SDI monitor system. The system comes with two receivers and two transmitters (the receivers are sold individually). The transmitter and receivers are portable, so you can use them separately or together. The transmitter has a 4-channel audio mixer, so you can monitor audio separately from video, and you can also remotely adjust audio levels. The SDI output is standard definition, but HDMI and 3.5mm audio outputs are also available. The transmitter has a 3.5mm audio output, and the receivers are also 3.5mm audio-capable, so you can easily connect a mixer, a recorder, or an audio transmitter, and route the audio to the receiver. The transmitter and receivers both have OLED displays. The transmitter has a 1.5-inch and the receivers have 0.8-inch displays, so both of them are big enough to display important data, such as battery power level, channel count, signal strength, and audio levels. The transmitter and receivers both have 3.5mm audio inputs, which makes it easy to connect audio devices such as a mixer or a recorder. The transmitter and receivers both support 5 to 12V DC power, and you can also use 6 to 16V DC power. The transmitter and receivers both support SDI-3G (3G SDI), SDI-HD (HD SDI), and SDI-2K (2K SDI) video formats. The transmitter and receivers both support SDI-3G(3G SDI), SDI-HD(HD SDI), and SDI-2K(2K SDI) video formats. The transmitter and receivers both support SDI-3G(3G SDI), SDI-HD(HD SDI), and SDI-2K(2 SDI) video formats. The transmitter and receivers both support SDI-3G SDI, SDI-HDSDI, and SDI-2K SDI video formats . The Mars 400S PRO is an affordable, professional-quality SDI monitor system.

The Hollyland Mars 400S Pro ($949.99) is, hands down, the best wireless video transmission system we've seen for camera monitoring. It has everything we wanted in a system, including low latency, multitasking, and a long range. It's the only system we've tested that transmits video over 400 feet, and it performs as well as or better than more expensive systems we tested. It's easy to set up, and it comes packaged with two chargers, two batteries, two cables, a transmitter, and a 400-foot Cat 6 cable. (The transmitter can also be mounted on a tripod.) The transmitter's display is bright and easy to see, and There's no need to worry about the transmitter overheating. Latency is extremely low, and the receiver supports multicasting, which allows you to transmit to up to 4 devices at once. The receiver has a 4K HDMI port, and supports 1080p, 4K, and 6K video. The receiver's display is bright, easy to read, and it has a touchscreen interface, so it's easy to navigate the menus. We also like the built-in audio mixer, which lets you adjust audio levels and set the audio source.

The Shimbol ZOlink 600 is a top-notch wireless HDMI and SDI video transmission system, making it easy to set up and link multiple cameras. It shoots at up to 1080P resolution and 60 frames per second, with no loss of picture quality. The transmission range is impressive, covering 600 feet, and the system supports 4K video transmission at 60 frames per second. The transmitter has a 3.5-inch OLED screen, so you can see your cameras at a glance, and the receiver has a 3.5-inch OLED screen. Both screens display important system information, such as video resolution, FPS, and battery level. The transmitter includes an infrared receiver, which helps you avoid running cables across a room. The transmitter and receiver feature infrared remote controls; the transmitter has a focus knob, and the receiver has a power switch. The transmitter and receiver both include power chargers. The transmitter and receiver both support wired remote controllers. The transmitter and receiver both support 3.5mm audio cables.

The Vaxis Atom 500 is an impressive video transmission system, especially for its size. The image quality is excellent, and the system's 300-ft range, low latency, and support for H.265 make it competitive with the best systems we've tested, including the Teradek Bolt Pro. The Atom 500's biggest drawback is the price: it's considerably more expensive than any of the systems we examined, and its smaller size means it's not ideal for large shoots. But if you're looking for an entry-level system, or if you simply don't need the long-range transmission range of the Atom 500, the AJA Cion is a worthy alternative.

The Shimbol ZOlink 600s is our favorite wireless video transmission system for broadcast-quality video. It transmits SDI and HDMI video up to 600 feet and includes a cold shoe mount, so you can easily mount it to a camera, tripod, or light. The ZOlink 600s is also extremely easy to set up, with no complicated equipment setup required. The transmitter and receiver are compact, lightweight, and silent, so you won't hear any fan noise while shooting. The transmitter and receiver both include a built-in OLED display, which displays data such as battery level, signal strength, and signal status. The receiver also has a built-in USB port for power, so you can easily power the transmitter and receiver from the same supply. The ZOlink 600s supports a variety of shooting modes, including single camera, dual camera, and IP-based streaming. The system includes a 10/100 Ethernet port for network monitoring and control.

The Mars 400S Pro is the most powerful wireless video transmission system we tested, and it's the only one with a built-in transmitter and receiver. But it's also more expensive and a little more complicated to set up than other systems we tested. The Mars 400S Pro is easy to set up, but it requires users to first connect each transmitter and receiver, and to set their channel numbers and baud rates. The Mars 400S Pro is also more expensive than other systems we tested. The units we tested from other systems, including the Mars 100S Pro, cost between $150 and $300. The Mars 400S Pro costs $499.99, plus $199.99 for a 5-12V battery and $129.99 for a 6-16V battery. Users also need to pay $39.99 for the optional transmitter or receiver unit. The Mars 400S Pro is more powerful than the Mars 100S Pro, which can only transmit video up to 150 feet, and it's also more expensive. The Mars 400S Pro also has better features than the Mars 300S, which can only transmit video up to 300 feet. The Mars 400S Pro, however, is more complicated to set up than the Mars 300S, which requires users to connect the transmitter and receiver by wires. The Mars 400S Pro also takes up more space than most of the other systems we tested. The other 4 systems we tested, including the Mars 100S Pro, the Mars 300S, the Mars 200S, and the Mars 100, are all small enough to tuck away in a camera bag, but they require users to connect each unit via wires.

The CVW Swift 800Pro is a top-quality wireless video transmission system that will satisfy most cinematographers, videographers, and DSLR users. We set it up for livestreaming, and it transmitted our video to a live-stream server with almost no latency. It delivers smooth, vivid images, and it supports multiple resolutions up to 1080p 60Hz. The transmitter and receiver each charge via a wall outlet, which means it's convenient to transport, and you can also charge your smartphone while it's transmitting. The transmitter and receiver each support three mobile devices simultaneously, and you can use any HDMI or SDI camera, and any smartphone or iPad (there are adapters for any of these devices).
