Domain(s) of application : Nuclear
No perturbation compared with a traditional video installation
o Parasites:
The traditional video signal is 1 V p to p .This video signal can receive by induction others signals. The result is bad pictures on the control monitor.
o Loops of ground:
This phenomenon gives unbalance of ground (frames jump on the screen)
o Magnetic fields:
Unfolding of frame; clearness problem, black bands.
o High Voltage:
Appearance of waves to the screen; colours attenuation; frequencies attenuation (range between 50 Hz and 6 MHz).
o Driving currents:
Video signal distortion, phenomenon “Boom row".
TRANSVIDEO PRINCIPLE :
A high frequency for each channel for transmitting : Video (up to 16 cameras); power supply ; Telemetry; Audio;
Dry Contacts.
ADVANTAGES
* Only one regular coaxial cable for: 16 cameras; power supply for each camera (9/12 v DC); 16 Audio; 2 Data links RS232
// RS485 // RS422 Full Duplex, 16 dry Contacts (alarms, remote control and so on)
* High frames quality (16 video signals simultaneously and real time: 25 frs/s per camera
* Compatibility with any type of camera and any existing video installation.
* Technical solution without equivalence in the event of impossibility of withdrawing of cable!
* Auto adaptation from 10m up to 1100m of cable.
* The installation time is reducing by 6.
* Product “Plug and Play”.
* High Technology directly resulting from the Nuclear technology; reliability tested more 10 years.
