Why use IR rather than radio?
Radio signals may cause interference, are easily detected and intercepted or may cause problems with munitions or flammable atmospheres.
Why is the Azdec system short range?
To make sure there is no ocular hazard we operate at low power levels.
Why is there a battery pack separate from the headset?
To provide 8 hours of typical use we need a battery of this size. We have a cordless headset with an integrated battery but time between charges is reduced.
Why are controls on the battery pack large?
Our systems are routinely used on naval vessels where the equipment is required to be used by operators wearing anti-flash gloves.
Why are the headsets relatively large?
Lightweight domestic headsets are not robust enough and do not provide adequate performance for professional use.
Can the system be used for data transfer?
We can very easily transmit data including streaming compressed video but the data rate is limited by the switching speed of the infra-red diodes to 0.5 Mbits/sec.
What naval vessels use the Azdec system?
The system is used by the UK RN on Type 23, Type 45 and RFA ships as well as IPVs & OPVs from around the world.
