Hollyland Syscom 421: 2 transmitters + 1 receiver

Hollyland Syscom 421-4 is a wireless HD video transmission kit (up to 1080p60) capable of transmitting and receiving up to 550 meters in optimal conditions. The set includes 2 transmitters with SDI-HDMI inputs capable of transmitting with a latency of 0.7ms against a single receiver, which in turn delivers 2 HDMI/SDI outputs.

It is also possible to connect the receiver to a LAN, allowing it to pass control signals back from a control panel to transmitters, allowing PTZ cameras to be controlled and tally information sent.

The transmitters have a Tally output port. Both units have an OLED screen that shows the resolution, the transmission channel, the signal strength and details such as the battery charge. The transmitter has a built-in L-series battery plate, and the receiver has a V-mount battery plate. Both transmitter and receiver feature 2-pin power input, for extended run times.

The transmitters are equipped with the L-series battery plate and the receiver is equipped with a V-Lock battery. Both the transmitters and the receiver can also be powered via a DC adapter.
