Chances are, you’ve used some pretty shoddy wireless I/O in the past.

Our wireless I/O is a little bit different. We’ve designed our system to be wireless right from the get-go, which allowed us the time and experience to deal with all the common issues faced by other wireless systems.

FINALLY, WIRELESS THAT WORKS. It’s been a long time coming, and now it’s actually here. Our wireless sensors and I/O have three major benefits over other wireless products out there in the market.

Narrow-band Frequency

Our wireless devices use 434MHz wireless comms, providing a range of up-to 2km line-of-sight.

Frequency Amplification

We can boost the wireless range further using our 868MHz wireless backbone module.

Device Hopping

Signals from other sensors or devices can be ‘hopped’ through powered devices for greater range.
