VoltRadar™ · Tripod-mounted voltage sentryGuard the whole work zone, not just one worker.
VoltRadar stands on a tripod at the edge of the job, up to 3.1 m high, and sounds a 90 dB alarm when live AC voltage is in range. Detection distances are set from a mobile app, so one unit can watch a crew, a crane or a section of line for up to 100 hours.
A fixed sentry for live electrical hazards

When the hazard is the site, not the task
Wearable detectors protect the person wearing them. VoltRadar protects everyone in the zone it watches. Set it beside an excavation near buried cables, a crane working under overhead lines, or a bay that must stay dead while work goes on.
- Detects live AC from 220 V to 66 kV, without contact
- Telescopic FRP pole on a steel tripod, adjustable up to 3.1 m
- 90 dB alarm with red LED alert
- Detection distances and thresholds configured from a mobile app
- 100 hours per charge; 11.1 V 5000 mAh Li-ion, USB Type-C, 4 h charge
- IP65 enclosure
Set it up in minutes
Power on
Press the on/off switch. The green LEDs light and a 1-second alarm confirms it is working.
Test
Check it near a live 220 V socket before deployment.
Position
Mount on the tripod, lock the legs and raise the pole to the height you need, up to 3.1 m.
Set and watch
Set detection distances in the mobile app. The green LED blinks every 5 seconds; a live field triggers a beep and red LED.
Built for the field
Remote configuration
Adjust detection distances, sensitivity and thresholds for different voltage levels from a safe distance, through the companion mobile app.
Mobile appHeight where it matters
FRP extension pole on a mild-steel tripod, adjustable up to 3.1 m to see over equipment and toward overhead lines.
Up to 3.1 mLoud enough for a site
A 90 dB buzzer with a red LED alert, so the whole crew hears it, not just one person.
90 dBSmartPause™
Silence the alarm while deliberately working in a known live zone; it re-arms automatically on exit, or by hand.
Auto re-armLong runtime
Internal 11.1 V, 5000 mAh Li-ion battery runs up to 100 hours and recharges over USB Type-C in 4 hours.
100 h · 4 h chargeWeatherproof
ABS enclosure rated IP65: dust-tight and protected against water jets from any direction.
IP65Detection distance by voltage
Default detection distances
| AC voltage | Distance (m) |
|---|---|
| 220 V | 0.15 |
| 11 kV | 1.9 |
| 33 kV | 2.2 |
| 66 kV | 2.5 |
Values from the VoltRadar TDS. Distances can be adjusted in the mobile app.
Tuned to your site
Out of the box VoltRadar warns at about 1.9 m from 11 kV and 2.5 m from 66 kV. From the app, a supervisor can set the threshold for each voltage level to match the site's safe working distances.
An early warning, not a permit to work. Non-contact detection tells a worker that a live field is near. It does not prove a conductor is dead. Keep isolating, testing with an approved contact tester and earthing before any work on a line, exactly as your safety rules require.

Safe deployment
Setting up
- Position the tripod securely and lock it to prevent tipping
- Confirm the green LEDs and the 1-second start-up alarm
- Test near a live 220 V socket before deployment
- Set detection distances in the app before work starts
During and after
- Use SmartPause™ with care, and make sure it has re-armed after leaving a live zone
- Check battery level and recharge over USB Type-C as needed
- Do not expose to rain or submersion beyond its IP65 rating
