Product Description

SZ Vodasafe VS-JD101 Professional Jamming Signal Detector
Description:
The SZ Vodasafe VS-JD101 is a professional jamming signal detector designed to safeguard fleet management systems and GPS tracking devices. Leveraging advanced fuzzy scanning technology, it efficiently detects jammer signals across a wide frequency range of 50 MHz to 6.0 GHz. Notably, it operates without interfering with essential wireless devices such as cell phones, WiFi, WLAN, Bluetooth, and DECT phones, ensuring seamless coexistence with normal communication systems.

Features
Precise Signal Detection with Visual Feedback
10-LED Indicator System: Displays detected signal strength in a gradient from green (low) to yellow (medium) to red (high), enabling intuitive real-time monitoring.
Wideband Coverage: Targets cellphone and WiFi frequency bands, effectively identifying GPS, GSM, and other signal jammers.
Advanced Noise Reduction Technology
Environment Noise Verification Circuit: Minimizes false alarms by filtering background interference. Features an H/L switch (factory-set to L) for adjusting noise tolerance in high-interference environments.
Flexible Relay Output for Emergency Response
1.0A Relay with NO/NC Outputs: Supports two SOS trigger modes for different GPS tracker brands:
Type 1: Holds the SOS button for 3+ seconds to auto-dial.
Type 2: Presses and releases the SOS button after 3+ seconds to trigger dialing.
Wiring Options: Use NO (Normal Open) for standard connections or NC (Normal Close) for instant triggering without the 3-second delay.
Adjustable Sensitivity for Customized Use
Sensitivity Tuner: Fine-tunes detection range (factory-set to ~5-minute position on a clock dial). Turn "+" to increase sensitivity (longer range) or "−" to decrease it (shorter range) for environments with extreme noise.

Operation Guide
Power Connection
Connect the red wire to the vehicle's VCC (+) and the black wire to GND (−), ensuring correct polarity.
The leftmost green LED and the trigger indication LED (top right) will light up to confirm proper operation.
Signal Detection Process
When a jammer signal is detected, the 10 LEDs will illuminate in sequence (green → yellow → red) based on signal strength.
Upon confirming a jammer signal, the relay output triggers the GPS tracker's SOS button to send a help warning. The trigger LED will turn off during this action.
Relay Output Wiring
Type 1 GPS Trackers: Connect relay NO/COM to the emergency button circuit (e.g., brown/red wires).
Type 2 GPS Trackers: Connect relay NC/COM to the GPS power input (e.g., orange/red wires) for faster triggering.
Environmental Noise & Sensitivity Adjustment
Noise Verification Switch
Located in the battery compartment, marked "H" (high) and "L" (low).
Default setting: "L". Switch to "H" only if frequent false alarms occur in high-noise environments.
Sensitivity Tuning
Use the built-in tuner to adjust detection range:
"+": Increases sensitivity (detects signals from farther distances).
"−": Decreases sensitivity (reduces false alarms in noisy areas).
Applications
Fleet Management: Protects commercial vehicles from GPS jamming during transport.
GPS Tracking Systems: Ensures continuous monitoring by alerting to signal interference.
Security & Surveillance: Ideal for detecting unauthorized jammers in sensitive areas.
Warning & Safety Notes
Auxiliary Use Only: This device serves as a supplement to supervision, not a replacement.
Liability Disclaimer: The manufacturer disclaims responsibility for losses due to misuse or malfunction.
Maintenance Restrictions: Unauthorized repair or disassembly voids the warranty.
Environmental Precautions:
Avoid exposure to water, extreme heat, or physical impact.
Do not touch the antenna to metal surfaces or signal emission sources.
Static & Feedback Damage: Warranty does not cover damage from static electricity or feedback.
Compliance & Warranty
All specifications are subject to change without prior notice.
