Professional-Grade 2-Wire Surveillance Kit for Kenwood Viking Radios

Maintain discreet, hands-free communication with this premium 2-wire surveillance kit engineered specifically for Kenwood Viking VP400, VP600, and VP900 portable radios. Featuring OSHA-compliant audio limiting technology and a piezoelectric accelerometer microphone, this kit delivers crystal-clear covert communications while protecting your hearing during extended operations.

Key Features & Benefits

• OSHA-Compliant Audio Limiter: Electronically limits audio to a safe maximum of 90dB, preventing hearing damage during extended use while maintaining clear communications
• Piezoelectric Accelerometer Microphone: Advanced throat microphone technology picks up voice vibrations directly from your vocal cords, ensuring clear transmission even in extreme noise environments
• Clear Acoustic Tube Earpiece: Discreet, transparent tube delivers audio directly to your ear canal while remaining virtually invisible
• Reinforced Cabling: Heavy-duty polyurethane sheathing (4.5mm main cable, 3.0mm earphone cable) withstands daily professional use
• Industrial-Strength Connectors: 35 lbs axial pull strength at PTT and connector, 15 lbs at microphone ensures reliability in demanding conditions
• Wide Temperature Range: Operates reliably from -30°C to +75°C (-22°F to 167°F) for all-weather performance
• Direct Connector: Purpose-built for Kenwood Viking series - no adapters required
• 12-Month Warranty: Comprehensive protection against manufacturer defects

Technical Specifications

Compatible Radio Models

This surveillance kit is engineered for direct compatibility with:

• Kenwood Viking VP900 - Advanced multi-band P25 portable

Why OSHA-Compliant Audio Limiting Matters

Many low-cost surveillance kits expose users to dangerous audio levels exceeding 100-110dB, unknowingly causing permanent hearing damage over time. Our OSHA-compliant audio limiter electronically restricts maximum volume to 90dB, protecting your hearing during extended operations while still delivering clear, intelligible communications. For situations requiring higher volume (such as extremely loud environments), kits with volume control override are also available.

Piezoelectric Accelerometer Microphone Technology

Unlike traditional air-conduction microphones that pick up ambient noise, our piezoelectric accelerometer microphone detects voice vibrations directly from your throat and jaw. This advanced technology ensures:

• Crystal-clear transmission in high-noise environments (construction sites, manufacturing facilities, concerts, motorsports)
• Elimination of wind noise during outdoor operations
• Covert communication without visible microphone elements
• Consistent audio quality regardless of ambient sound levels
