Know Before
They Arrive
WaveGuard passively detects TETRA emergency vehicle transmissions as far as over 500 meters away, giving you time to react. Compact enough for a biker's backpack. Works in any car. No subscription. No cloud. No complicated installation.
How It Works
No installation. No tools. Works in any car, or just drop it in your backpack for the ride. WaveGuard is as simple as charging your phone.
Power Up & Go
In a car: plug into any USB port or 12V outlet. Done. On a bike: pair it with a small power bank and drop it in your backpack. No installation, no drilling, no permanent changes to anything.
Open the App
Download the free WaveGuard app on your iPhone or Android phone. It connects to the device over your car's hotspot in seconds, no account, no setup wizard, no pairing codes.
Drive or Ride with Confidence
WaveGuard monitors silently in the background. The moment an emergency vehicle is detected nearby, you hear an audio alert and see real-time proximity on screen.
Built to Detect. Designed to Drive.
Every feature is calibrated from real-world testing on European roads, not a lab. WaveGuard works where it matters.
Always-On Detection
CoreWaveGuard listens continuously, even when the vehicle is not yet transmitting voice. It picks up the steady background signal every emergency vehicle broadcasts at all times, so detection starts long before they're nearby.
Over 500 meters Early Warning
500+ metersWaveGuard picks up signals as far as over 500 meters away. That gives you time to calmly change lanes, ease off the throttle, and make space safely.
Multi-Vehicle Tracking
3 tracksTracks up to 3 emergency vehicles simultaneously, each with its own signal-strength display, proximity tier, and independent alert, so you're never caught off guard when a convoy is approaching.
13-Tier Proximity Display
From directly beside you to far away. As the vehicle approaches, your signal bars climb and the alert tone becomes more urgent, giving you a clear, intuitive sense of distance at a glance.
City Mode
Dense urban environments can produce background interference. City Mode automatically adjusts sensitivity so you only hear alerts for vehicles that are genuinely close, not noise from two streets away.
Smart Filtering
Near 0 false positivesWaveGuard's detection engine is purpose-built to distinguish genuine emergency vehicle signals from other radio traffic. The result: virtually zero false positives, even in busy city centres.
Adaptive Audio Alerts
Different beeps for different distances. Alert tone and repeat rate scale with proximity, a gentle notice at distance, an urgent warning when they're close.
Car, Bike, Anywhere
WaveGuard is compact enough to sit in a biker's backpack, just add a small power bank and ride. Or unplug it from one car and move it to another in seconds. One device, every trip.

View full coverage map →WaveGuard is a passive receiver. It transmits nothing, does not interfere with any network, and does not decode or record the content of any communication. It only detects the presence and signal strength of transmissions. Rules on the use of receiving equipment differ per country. Check what applies where you live before using it.
None at all. In a car, it plugs into any USB port or 12V socket like a phone charger, no cables to hide, no brackets, nothing permanent. On a motorcycle, just pair it with a small power bank and slip it into your backpack. Ready in under a minute either way.
Proximity tiers are calibrated from real-world testing on European roads. At close range the system is highly reliable. Range can vary depending on terrain and your local environment, open motorways tend to give longer range, while urban areas may be shorter. City Mode adjusts sensitivity automatically in dense environments.
