Information

S-4904P Broadcast/Film industry wireless system supports uncompressed 3G/HD/SD-SDI and HDMI to transmit 1000 meters (Line-of-Sight) distance, at less than 1 millisecond latency.

WHDI wireless transmission
1000 meters (LOS) with Panel Receiver
S-4904P Broadcast/Film industry wireless system is based on WHDI wireless technology, 5.1-5.9GHz license free bands, with a new developed high Gain Panel Receiver, supports uncompressed 3G/HD/SD-SDI and HDMI to transmit 1000 meters (Line-of-Sight) distance, and less than 1 millisecond latency. The system is pure hardware connection, plug and play, which is widely used in director monitoring, drone, ropeway camera, steadicam etc.

The Transmitter
The Transmitter has 2 omni antennas, signal interfaces are:
1x 3G/HD/SD-SDI input
1x HDMI 1.3 input
(If both SDI and HDMI are connected, the system transmits SDI as priority.)
1x 6-17V DC input

Panel Receiver
The Panel Receiver adopts 14dBi high Gain Panel Antenna and build-in wireless receiver design, to set up by lighting tripod.
The Panel Receiver interfaces are:
1x 3G/HD/SD-SDI output
1x 7-36V 4pin LEMO DC input

1000m Transmission
In Line-of-Sight, S-4904P supports non-compressed 3G/HD/SD-SDI and HDMI 1000 meters (3300 feet) transmission, with less than 1 millisecond latency.

Embedded Audio Transmission
S-4904P supports SDI and HDMI embedded audio (CH1&2) transmission.

5.1-5.9GHz Frequency
S-4904P wireless system works at 5.1-5.9GHz License-free frequency. The frequency bands are user configurable and support 3-4 pairs wireless channels to work together in one location. The wireless output power is less than 63mW, which will not do harm to human bodies.

Multicast Setting
Users can set several Receivers at the same frequency point as the Transmitter, to enable 1 Transmitter to multi Receivers multicast mode.

Power Supply and Set-up
Transmitter: Equipped with V-mount or Gold mount battery plates, so you can install the transmitter between camera and battery, and to power the transmitter and camera together. You can also power the transmitter via 5.5/2.1mm pole tap DC-IN, input voltage 6.5-17V.

Receiver: Provides VESA bracket to set up on lighting tripod, and power via 4-pin LEMO DC-IN, 7-36V. The package also provides V-mount or Gold mount battery plate with clamp, to install battery on lighting tripod.

Standard Package
S-4904P package includes:
1x Transmitter (V-mount / Gold mount option)
3x Antennas (For transmitter, 2+1 backup)
1x Articulating arm trestle (Cold shoe and 1/4")
1x D-tap DC cable (For transmitter)
1x Band switching driver (For transmitter)
1x Panel Receiver
1x VESA bracket for lighting tripod (For Receiver)
1x D-tap to 4-pin LEMO DC cable (For Receiver)
1x Battery plate with clamp (V-mount / Gold mount option)
1x Carrying case (for everything)
