Direct hardware sale is pending Indonesian import and distribution licensing. Today the unit is available deployed within a Zentara engagement — or request a demonstration and we'll notify you when direct purchase opens.
Complete detection capability
Three vectors. One sweep.
A bug can transmit over the air, ride a cable, or watch through a lens. M7 covers all three in a single kit.
Wireless threat detection
- Covers 50 kHz – 12 GHz
- Detects GSM, 2G, 3G, 4G, 5G
- Wi-Fi, spread-spectrum & frequency-hopping
- Audio & video transmitters
Covers both legacy and modern surveillance technologies.
Wired threat detection
- Smart cable analyzer — LAN, RJ45, RJ11, spare cables
- Mains carrier probe — live-earth, live-neutral scanning
- Automatic scanning combinations
Faster sweeps. Reduced human error.
Hidden camera & optical detection
- Detects hidden camera lenses — even when powered off
- IR, laser & visible-beam transmitters
Complete physical inspection capability.
Precision intelligence control
Find the signal. Then find the source.
Detection is only half the job. M7's control unit turns a reading into a location — and a location into evidence — with live analysis on a high-resolution display.
Intelligent RF probe
Auto-adjusting detection across omni-directional and directional antennas — identify and localize wireless transmitters fast.
- Omni-directional antenna
- Directional antenna
- Ultrasonic activation for VOX transmitters
Distance measurement
Close on the source, not just the signal. Pinpoint a transmitter down to a centimetre.
- Live signal analysis
- Pinpoint accuracy up to 1 cm
- VOX-aware localization
Recording & evidence
Keep full documentation for operational review or legal evidence — recorded on the device.
- RF signal recording
- Audio demodulation files
- Micro SD storage

One family · protect, detect, deny
M7 finds it. The family protects and denies.
Detect the implant with M7, then protect the room with the GT series — or let our operators run the whole sweep.
Secure your environment with confidence.
