The Hollyland Syscom 421-2TX (2x Transmitter, 1x Receiver) bundle is a professional, multi-camera wireless video transmission kit engineered specifically for mid-sized live broadcasts, multi-cam live streaming, and commercial video sets.

By utilizing a multi-channel receiver hub, this system allows two independent cameras to broadcast real-time video to a single central receiver over a single RF channel, drastically saving valuable wireless bandwidth and preventing frequency congestion on a busy set.

Core Hardware & Kit Inventory

  • 2 × Syscom 421 Transmitters (TX): Mounted onto your individual camera rigs. Each unit accepts both 3G-SDI and HDMI video feeds up to 1080p60 and transmits them over a massive 1,800-foot (550m) Line-of-Sight (LOS) range.

  • 1 × Syscom 421 Multi-Cam Receiver (RX): Positioned at your director's station or video switcher booth. It simultaneously picks up both video feeds and outputs them across 2 dedicated HDMI and 2 3G-SDI ports.

  • 15 × High-Gain 5GHz Antennas: This generous count is mathematically designed for field redundancy. Both transmitters and the receiver require 4 antennas apiece to run their high-throughput MIMO (Multiple-Input Multiple-Output) wireless arrays (4 x 3 = 12 antennas in active use). Hollyland provides 15 total antennas in this package so you have 3 complete spares on hand if an antenna breaks or goes missing during a chaotic build.

  • 2 × Articulated Magic Arms (7-Inch): Heavy-duty friction mounts used to securely clamp each of the two transmitters onto your cameras' cages, top plates, or cold shoes without slipping during rapid pans.

Pro-Tier Multi-Cam Integration Features

  • Bidirectional PTZ & Tally Control: The system passes data back and forth seamlessly. It includes integrated RS-485/RS-422 serial links and RJ45 network terminals, allowing a technical director at the switcher booth to send remote PTZ (Pan-Tilt-Zoom) joystick commands back to a robotic camera rig. It also pushes physical Tally light data to notify operators and on-camera talent which feed is currently "live."

  • Wired Ethernet RTSP Streaming: The receiver hub features a native LAN port. You can plug it straight into a local router or streaming computer to execute direct RTSP network pull-streams, simplifying workflow routing into software switchers like vMix or OBS Studio.

  • Flexible Broadcast Power Solutions: Built for continuous deployment. Every unit features a rear-mounted Sony NP-F (L-Series) battery plate for mobile or handheld operations, alongside a locking 2-Pin LEMO DC barrel input (7–36V) to draw robust, continuous power directly from a cinema camera’s V-mount or Gold-mount D-Tap distributor block.

Technical Specifications Matrix

Feature Specification
System Scalability Limits Out-of-the-box 2TX setup (Scalable up to 4TX total to a single RX)
Maximum Operating Range Up to 1,300 Feet (400m) standard / 1,800 Feet (550m) Max Line-of-Sight

💡 On-Set Channel Allocation Tip: Because this system encodes multiple video links onto a single 40 MHz channel block, it makes multi-camera operations incredibly clean. If you need to expand your coverage down the road, you do not need to buy a completely new wireless system or worry about frequency coordination—you can purchase individual standalone Syscom 421 transmitters later and sync up to four cameras total directly into this exact same receiver hub.

Beautiful & Great Price!
Color: Gold-b, Color: Gold-b
I was looking at a $60 Williams & Sonoma “honeycomb collection” marble paper towel holder with gold bee accents, but decided to save a bunch of money and go with this one. Glad I did! It’s awesome!!! Easy to put together with the wrench that’s included, it’s packed well - great product for the price and they sent a free gift with it too. Received 3 super soft dish cloths along with the paper town holder. Unexpected surprise and happy with them too!! Just placed an oder for another one for the other bathroom sink. This will not be in a high use area so I’m not worried about the base getting beat up. I feel like it’s just the right weight. Not as heavy as real marble, but heavy enough to hold the towels securely. The gold is a pretty shade.

Heavy marble base and solid rod holder.
Color: White-aa, Color: White-aa
After researching the many different marble base towel holders, which is what I wanted to match my marble decor, I finally settled on this which arrived today, packed very nicely in a Styrofoam tight box to protect the marble and came with it as you can see a gift of some very soft Microfiber dish cloths, which work very well at removing smudge marks on kitchen appliances. It took me 30 seconds to join the base to the rod. It came with a little tool to tighten the base however it really wasn’t necessary. I then covered the hole under the base with a piece of One-sided circular sticky, felt, which covered the hole very nicely. I have tried it, and it does do as it says, and the marble base is heavy enough where it holds the roll of paper towels so that with a couple of tugs, I can get one of the perforated sections out. Does take more than one tug as some people showed but two tugs or three light ones really doesn’t matter it gets the job done and in a far lower price than any of the others, in fact, some of the recommended others were 2 1/2 times more expensive and the reviews were not good at all. It pays to take the time to go through people’s reviews like mine and that’s why I believe in completing the reviews whenever I can time permitting. I’m giving this a five star and I think that you will too. I was lucky based on some of the other marble bases that were shown for this product that I got a significant amount of gray marbling matter because some of them had very little it’s just the way the marble runs and you take your chance, but I was lucky.

Nice touch!
Color: Gold-b, Color: Gold-b
Handles large paper towel rolls. The gold color on the top which is mainly what you see when you have paper towels on it, coordinates nicely with the various shades of gold in my kitchen. The 4" pulls brushed gold, the Delta pull down facet as well as the Euro (Lamps plus) aged brass mini pendant. I find it easy to tear off paper towels even without the small tear bar found on different holders. Was a few $ more but it matches perfectly. Well worth it.
