SENTRA-One

Fundamental Signal Awareness for Basic Field Needs

Product Overview

SENTRA-One is an ultra lightweight, entry-level mobile signal scanner designed for organizations that require IMSI presence detection.

This device prioritizes simplicity, durability, and affordability, offering foundational signal awareness without any form of tracking, band selection automation, or mobile app functionality.

Primary Features

  • IMSI Detection: Detects IMSI numbers—not continuous scanning.
  • Single Narrow-Band Receiver: Supports only one narrow LTE frequency range, not full-band scanning.
  • Fixed Internal Antenna: A non-replaceable, low-gain antenna (no omnidirectional capability).
  • Battery Life 15-20 Minutes: Offers a 15-20 minute runtime on a full charge.
  • Rugged Basic Housing: Durable casing for rough handling in field training or basic patrol use.
