CSI visualizer
Explore live Wi-Fi Channel State Information through amplitude, phase, and I/Q views. This advanced view pauses normal motion sensing while the signal stream is running.
Inspect the signal behind detection
The CSI visualizer shows amplitude, change, phase, and I/Q views of a live stream from your device. It also shows the packet rate, dropped packets, RSSI, SNR, and capture timing.
While the stream runs, motion sensing is paused. The data goes straight from the device to this browser; the website does not upload or store it.
This device cannot open the CSI visualizer
The installed firmware does not support the CSI visualizer.
Subcarrier amplitudes
LIVEEach line tracks one subcarrier across the rolling time window. Colors distinguish lower, middle, and higher frequencies.
Connected. Start the temporary signal stream when ready. Nothing is uploaded or stored.
This device is waiting for an external Wi-Fi traffic source. If the view stays empty, change the traffic source.
