SWIT FLOW500 Tx | 500feet(150m) new generation Wireless FHD Video Transmitter, Super Anti-interferen

The SWIT FLOW500 Tx is a next-generation wireless Full HD video transmitter using KUWI 5.1–5.9GHz technology. Supporting 3G-SDI and HDMI (up to 1080p60), it delivers stable, low-latency transmission up to 150 meters (500 feet) with strong wall penetration, multicast capability, and dual encryption security.

The SWIT FLOW500 Tx wireless transmitter is built on SWIT’s advanced KUWI wireless technology operating in the 5.1–5.9GHz band. Designed for professional film, broadcast, and live production workflows, it transmits uncompressed 3G/HD-SDI and HDMI signals up to 150 meters (500 feet) line-of-sight with exceptional stability and minimal delay.

Equipped with 1× 3G/HD-SDI input, 1× SDI loop output, and 1× HDMI 1.3 input, the FLOW500 Tx supports resolutions up to 1080p60. The SDI loop output allows simultaneous local monitoring while transmitting wirelessly.

High-Performance Wall Penetration

Through RF and image optimization, the FLOW500 offers enhanced stability when transmitting through walls or obstacles, making it ideal for complex shooting environments.

OLED Display & Smart Channel Selection

The built-in wireless scanner automatically detects frequency conditions and selects the most stable channel. Users can also manually choose from 7 non-DFS channels. The OLED screen displays video format, channel number, and signal strength in real time.

Multicast & Double Encryption

The system supports 1 transmitter to up to 4 receivers in multicast mode. Pairing uses a private wireless protocol combined with AES-128 encryption, ensuring secure and interference-resistant transmission.

Reclocking & Accurate Color Reproduction

The FLOW series supports signal synchronization (reclocking) to maintain black level accuracy, reduce noise, and preserve faithful color reproduction.

Flexible Power Options

The transmitter features:

• NP-F battery plate

• Lockable 7–34V DC input

• Power consumption below 8W

A Micro USB port enables USB OTG firmware updates for future enhancements.
