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

💡 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.

need a smooth sink surface for this to work
Color: Silver
Suction cups didn't stick to my sink and kept falling; to be fair, surface of my sink is textured.

Three months later, it's a keeper
Color: Silver
I hate it when reviews are left one day after the product arrives. At that point, there's no way of knowing if the item is going to last. When my last sink caddy went bad (the suction cups rotted out and the wires had started to rust), I ordered this as a replacement. Inexpensive, functional, worth a try. There were two things that impressed me when this arrived. The suction cups weren't permanently mounted, so if they fell apart, the caddy was still worthwhile. Secondly, the company offered free replacement suction cups if the time came I needed them. That struck me as above-and-beyond; I had no idea this was part of the package. I'm happy with this. It looks good, I detach the sink caddy regularly when I want to move it out of the way, and it pops right back into place. For the money, I don't think you can beat it.
