1 WIRELESS MONITORING SOLUTION
2 Program Introduction Presentation of the WMS System Practical briefing Summary
3 About VTQ almost 50 years history of the company over 175 employees developer and manufacturer of professional wireless systems electronic manufacturing services (EMS)
4 Concept and target group professional wireless monitoring system application: on filmsets, serial and commercial spot productions user: directors and video assistants
5 Transmitter Receiver Free Mount Handheld RX Outdoor RX G-Mount V-Mount V-Mount RX Receiver
6 Features powerful plug-and-play monitoring system stable COFDM transmission no fragile WiFi or OFDM (DVB-T based), high HD video quality thanks to broadcast standard encoders transmission even without line-of-sight (NLOS) thanks to narrow bandwidth of 8MHz (instead of 40MHz at OFDM)
7 Features rugged aluminium housing for professional and uninteruptable work on set quickly ready for action through simple appliance concept interference free transmission up to 2400m at HPQ and 3000m at HG very low latency, only 22ms (Encoder/Decoder) overvoltage and reverse-polarity protection
