Vivotek AMN-M21-02 Dual External LTE Antenna

Vivotek AMN-M21-02 Dual External LTE Antenna

The Vivotek AMN-M21-02 is a dual-antenna external LTE package engineered for the Vivotek NV9x21P series network video recorders. This antenna solution delivers reliable 4G/LTE cellular backup connectivity for surveillance deployments where wired network infrastructure is unavailable, unreliable, or impractical. The dual-antenna configuration enables flexible RF positioning to maximize signal strength and coverage in challenging environments, making it ideal for remote monitoring, mobile deployments, and locations with limited or no fixed network access.

Key Features

• Dual-antenna design optimizes signal reception and transmission in weak RF environments
• Direct compatibility with Vivotek NV9x21P series NVRs
• External antenna form factor allows flexible positioning for line-of-sight optimization
• Supports LTE/4G cellular redundancy for continuous video surveillance monitoring
• Includes mounting hardware and connection cables for rapid deployment
• Enables deployment flexibility across temporary, mobile, and remote surveillance applications

Technical Highlights

The dual external antenna design provides superior RF signal capture compared to internal antennas, particularly valuable in areas with marginal cellular coverage. The flexible positioning capability allows installers to orient each antenna independently for optimal signal strength, reducing dead zones and improving connection stability. This configuration supports seamless LTE/4G failover, ensuring uninterrupted video transmission even during primary network outages.

Typical Applications

• Remote facility monitoring with limited network infrastructure
• Temporary and event-based surveillance installations
• Mobile surveillance units and vehicles
• Cellular backup for primary network-dependent deployments
• Areas with poor fixed broadband availability
