V-Max 5.8 GHz Wireless Video
Audio and Data Transmission System

VMax 5.8 GHz Series Video/Audio/Data Transmission System

WTI’s V-Max series is the ultimate solution when conventional cable installations are impractical or impossible. It can provide simultaneous real time transmission of video, dual-channel audio and/or RS-232 data. It provides exceptional wireless performance in all climates and is unaffected by fog, rain, or snow.

WTI V-Max goes where cable can’t - in all climates and adverse conditions.

A Multitude of Features

• 16 field-selectable channels of operation
• High density co-location potential
• System comes complete. No extras to purchase
• Utilizes high-technology Phase-Array microstrip antennas
• Two sub-carriers for audio or data. Optional transmitter modules provide for input of line-level audio, microphone, RS-232 data, or contact closures. Optional receiver modules provide for output of line-level audio, speaker drive, RS 232 data, or contact closures
• Audio and data interfaces are fully isolated to eliminate ground loop problems
• Seamless operation with any WTI PTZ data system
• Optional thermostatically controlled heater
• No user license required

There are Three V-Max Systems to Choose From:

V-Max I
This system is for moderate range transmission up to two miles. The V-Max I utilizes an internal Phased-Array microstrip antenna on both the transmitter and receiver.

V-Max II
This system is for longer range transmission up to four miles. The V-Max II transmits with an internal, Phased-Array microstrip antenna and receives with an external, mast-mounted, low-gain, dish antenna.

V-Max III
This system is for distance transmission up to six miles The V-Max III transmits with an internal, Phased-Array microstrip antenna and receives with an external, mast-mounted, high-gain, dish antenna.
