iProtect DD1240 Microwave & Millimeter Wave Detector

Most RF detectors stop at 6 or 8 GHz. Modern surveillance devices don't.

The iProtect DD1240 scans frequencies from 9 GHz all the way to 44 GHz — the ultra-high microwave and millimeter-wave bands where next-generation bugs, covert transmitters, and 5G-based surveillance devices operate. If your current sweep equipment tops out below 10 GHz, you have a blind spot. This closes it.

Why the DD1240 Matters

Eavesdropping technology has moved into frequency ranges that conventional bug detectors simply cannot reach. Millimeter-wave transmitters are smaller, harder to find, and increasingly common. The DD1240 was purpose-built to detect RF energy in these upper bands with approximately -40 dBm sensitivity — enough to locate low-power covert devices at close range.

Three Search Modes for Any Environment

• Silent Mode — Visual-only detection using the OLED display. Ideal for discreet sweeps in offices, boardrooms, or hotel rooms where audible alerts would draw attention.
• Alarm Mode — Audible alert triggers when RF energy is detected above threshold. Useful for rapid sweeps of larger spaces.
• Sound Mode — Demodulates detected signals so you can listen to the transmission content through the built-in speaker, helping you identify the source.

Dual-Level Detection Scale

The DD1240 displays both Modulation Level and RF Level simultaneously, giving you two independent data points to distinguish real threats from ambient interference. The 30-degree directional antenna pattern lets you pinpoint a device's location by narrowing the signal path as you sweep.

Built for Fieldwork

At just 172mm long and under an ounce, the DD1240 is roughly the size of a pen. The duralumin housing is lightweight and durable. A single AA battery delivers 10–20 hours of continuous scanning — enough for multiple full-room sweeps without recharging.
