4K optical transmission for Panasonic AW-UE150


The users of the Panasonic AW-UE150 PTZ camera are going to enjoy the featured Ereca TOPAS 4K allowing to transmit all signals over fibre and remote power the UE150 camera.


Topas 4K is specially designed and shaped to complete perfectly the UE150.
The mechanical interface of the transmitter enclosure has been precisely cut so it matches the camera bottom and mounting bracket for quick and easy installation while staying visually discrete.

The transmission module works with standard SMPTE cables (Lemo and Neutrik) and allows to power remotely the UE150 camera and the Topas 4K transmitter over 800 meters. The transmitter is also available with local power option and SC/APC connectors.

The receiver side comes with two options:

  • A standalone half rack 1RU receiver with remote power capacity and basic diagnosis.
  • For Cam Racer’s owners, the Topas 4K transmitter has been made compatible with the Cam Racer basestation receiver (signals and power), offering a complete solution comfortable to use with embedded web management and detailed diagnosis.
Topas 4K - RX (front & back)

Each TOPAS 4K system transmits the following signal set:

  • 1 x 12G SDI signal from Camera,
  • 1 x 3G SDI signal from Camera,
  • 1 x HD SDI monitoring signal from Camera,
  • 1 x HD SDI from basestation (return path),
  • 1 x Genlock from basestation (Composite video / Black burst / Tri-level),
  • 2 x Audio from basestation (can be optionally shared with LANC remote signal),
  • 1 x Ethernet 10/100 Mbps,
  • 1 x Serial data RS 232/422/485,
  • 1 x Tally Contact closure from basestation.

A small internal silent fan provides cooling of the transmitter electronics and
power supply section.
