NS Optical Fiber Conversion Camera System

NS Optical Fiber Conversion Camera System camera recorder signals of shoulder types and handy types are transmitted through optical fiber cable.
One optical fiber cable enables long-distance transmission of video signal, microphone sound, AES/EBU, return signal, tally signal, intercom, camera remote controller,GENLOCK signal, and LAN needed for system camera (studio). (some models are excluded such as LIGHT type etc.)
Optical Fiber Conversion Camera System NS series can be select from 3 types, such as NEUTRIK, TAJIMI, and LEMO.

ENG camera can be used for studio and field recording and event multi recording.

NSR series for 4K signal by 12G-SDI

NSR-X412 can transmit by 5 x 12G/6G/3G/HD-SDI, 2 x RET6G/3G/analog, 2 x Intercom, LAN, and can output 170W power supply.(*)
Carbon casing with lightweight and high hardness (Option).
Besides, NSR-X4, which can transmit by 3G/HD-SDI, and NSR-X1, which can transmit by HD-SDI, RET3G/analog, are newly released.

*The value is the maximum instantaneous output, and not support continuous output. Moreover, the continuous output value varies depending on the using condition.


Build-in patented optical fiber transmission technique, transmitting SDI/analog image without input switching. No switching is more helpful!

Digital channel can connect almost all formats of SD-SDI/HD-SDI/3G-SDI, composite, HD-Y, and SYNC like being connected with BNC cable. (Some models are excluded.)
Transmission (PAT) is possible without any settings in switching and the like.
SD-SDI/HD-SDI/3G-SDI support LevelA/B.
It conforms to the following transmission specification.

  • SMPTE 125M: NTSC(480i 59.94)
  • SMPTE 292M: 1080i 50/59.94/60, 1080p 23.98/24/25/29.97/30
  • SMPTE 296M: 720p 50/59.94/60
  • SMPTE 424M: 1080p 59.94/60(3G)
  • PAL(625i 50)


It can transmit without missing data, with ANCI area and embedded audio being remained as they are. (There are some models with SDI dedicated line and terminal.)

All signals can transmit either synchronous or asynchronous.

All video signals can transmit asynchronously.
It can transmit mixed signals of 8K and 4K.
Signals of disparate formats can be transmitted with no problem.
It will useful in reporting collaboratively with other stations.
It is possible to transmit different synchronous signals from base station.

4 types of power supply method selectable connecting method in accordance with the situation

In feeding to the camera adaptor from base station, it can be used NEUTRIK/LEMO/TAJIMI camera cables, DC12V external input, battery, or power feeding unit which operate with optical fiber cable only (about 10 to 20km can be possible) between camera adaptor and base unit.

Certainly real-time transmission.
Safety transmission without a bug when power interruption occurs.

Power switch is removed except base unit.

PROTECH Optical Conversion System as well as LS series and PS series are OK to switch off the base station abruptly.
It prevents accidents arised from switching off by mistake.
Power ON/OFF operation can be performed only on the base unit.
(Please power ON/OFF your cameras according to the manuals.)

In addition, it displays if it has plenty of power energy in base station side.
Signal monitor is standardly equipped except for NS LIGHT to know accurately which signal has transmitted.

A single fiber can transmit a large amount of data.

A single fiber cable can transmit signals bidirectionally in large stadium, ski ground, and arena using single fiber conversion box NS-BSCT and NS-CSCT TAJIMI type.
It can transmit for a maximum 4K x 2.

Optical Conversion Camera System with high reliability and great achievement

It is daily used in fields, for example, LS/PS for drama, outside broadcast, and studio filming, 4KLS system for 4K live filming etc.
It is designed to work the function if adaptors being connected have same functions, by making signal processing of NS series in common.

Transmission comfortably in every camera

It supports almost all the HD cameras and 4K cameras.
Since it is not an exclusive transmission device, it supports any type of camera. (Some models are excluded.)

System construction with PROTECH products will lead to improvement in box type lens adapter, view finder, and solve return switching problems.

Adapter HDS-1500RT which attaches camera to box type lens is fully loaded with functions needed in fields, such as return function (PAT), iris incorporating (PAT), return switching in view finder (PAT), return switching in optic camera (PAT), connecting handset to camera adaptor (handset) (PAT),and transmitting SDI and composite without switching (PAT) etc.

Dedicated to Canon latest model EOS C500MK II Studio use optical fiber camera adaptor.
