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 renders amplitude, change, phase, and I/Q views from a temporary stream produced by compatible firmware. It also reports delivery rate, dropped packets, RSSI, SNR, and capture timing.
Starting the stream pauses normal motion sensing until you stop it. Signal data travels directly from the selected device to this browser and is not uploaded or stored by the website.
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.
