Product introduction 

This broadcast industry wireless system includes S-4904T transmitter and S-4990 receiver, adopts WHDI 

(OFDM) technology, supports uncompressed 3G/HD/SD-SDI and HDMI

 

wirelessly transmitted in 1000 meters

 

scale, and with less than 1ms latency, which is widely used in on-site shooting and director monitoring. 

 

Features 

  Uncompressed 3G/HD/SD-SDI and HDMI transmission 

Support up to 1080p 50/60 uncompressed SDI & HDMI wireless transmission 

 

  1000 meters transmission distance 

In open outdoor area, the effective transmission distance is approx 1000 meters. 

 

  Less than 1ms latency 

There’s no discernible video delay and you can use it as real time on-location monitoring. 
 

  License free operation frequency 

The wireless frequency is 5.1-5.9GHz, license free operated. 
 

  Frequency channel selection 

Adopt buttons to select frequency channel and digital tube to display, easier to operate. 
 

  Multicast support 

Support one transmitter to multi receivers. User can set frequency to pair the transmitter and receivers.   

 

  Battery plate optional 

User can choose Gold mount or V-mount battery plates for S-4904T transmitter. 

 

  All-Metal Shell 

Both the transmitter and receiver adopt metal shell which is durable and solid. 

 

  Simple connection   

The wireless system is plug-and-play designed, without any software connection and configuration. 

 
 
 

Remark: 

1. The transmission distance may be different, and depend on surroundings, radio wave conditions, buildings, 

etc., the 1000 meters transmission distance may be not guaranteed. 

2.  The  wireless  transmission  might  be  interrupt  if  there’re  many  other  devices  of  5GHz  wireless  bandwidth 

operated in the in the same location. 

3. Signal reception may be affected by the position, height and angle of devices. If reception video is not stable, 

please physically adjust placement for the optimized signal. 

4. Open the antennas at various angles and set receiver higher will enhance the transmission efficiency. 
5. The product offers the AES 128-bit encryption to protect the wireless transmission. Anyway, please be ware 
of the intentional capture from third person.
