Free Space Opical Transmitter for Elevator
 

Video Transmission System For Elevator
SOT-AV Series
 

Feature

Ideal models specialized for applications on moving elevator, etc.
Transmission ranges of 70/130/250 m with small and compact design
Designed for simplified installation and connection
Wiring and other work are not necessary thanks to cable-less design.
Range can be extended up to 450 m.
Since it is free from restrictions under laws, it is ideal also for applications where it is difficult to wire cables
crossing a public road,for example.
Being immune to disturbance by noise, it can be used in very noisy environment.
FM modulation by this space optical picture transmitter hardly
