TAU S.r.l. Two-channel transmitter, rolling-code technology, 433,92 MHz frequency, Green LED.
Range: up to 200 m in open air (the effective range depends on terrain and possible radio frequency interference)
281,000 billion code combinations
Virtually impossible to duplicate
Rolling code technology: every time the transmitter sends a code, it generates a new code using an encoder. An algorithm identifies and validates only the signal of the transmitter encoded by the radio receiver.
