AI-Powered Detection

Advanced artificial intelligence analyzes WiFi signal patterns in real-time, distinguishing between normal household movement and potential intruders. The system learns your home's patterns and only alerts you to genuine threats.

Training Mode

Spend just 2 minutes walking around your home to teach the AI your normal movement patterns. The system learns your environment and becomes more accurate over time, reducing false alarms while maintaining maximum security.

How Training Works:

Walk through your ENTIRE home (all rooms, upstairs, downstairs)
App collects WiFi signal strength from every location
Calculates baseline that includes normal variations throughout the house
AI learns the "normal" signal pattern for your specific home

Works for All Home Sizes:

Training captures signal drops from walking between rooms
AI learns these are normal household movements
Only detects NEW patterns (intruder in different location)
Works for single story, double story, or mansions

Example: Small house: Baseline -60 dBm, variation ±5 dBm | Big house: Baseline -65 dBm, variation ±12 dBm

Smart Learning

When you receive an alert, you can mark it as a false alarm or confirm it as real. The AI learns from your feedback, continuously improving its accuracy and adapting to your specific home environment.

No Additional Hardware

Transform your existing WiFi network into a sophisticated motion detection system. No cameras to install, no sensors to mount, no monthly subscriptions. Your phone and router are all you need.

Privacy First

Unlike traditional cameras, Nagvalk never records video or images. It only monitors WiFi signal strength changes, ensuring complete privacy for you and your family while maintaining top-tier security.

Instant Alerts

Receive immediate phone calls when motion is detected. The voice alert repeats multiple times to ensure you hear it. You can then confirm if it's a real threat or mark it as a false alarm to help the AI learn.

Phone Call Alerts

Get instant phone calls when motion is detected. The system calls your number with an automated alert message that repeats until answered, ensuring you're notified immediately even if you're away from your phone screen.
