Guard-Dog Detector – Automatically detects cell phones, Wi-Fi & Bluetooth
Guard-Dog – The intelligent guardian for wireless security
Maximum control. Instant detection. Absolute security.
In a world where mobile phones, smartwatches, and Bluetooth devices are ubiquitous, controlling wireless activity in sensitive areas becomes a critical security task. Whether it's a correctional facility, military installation, research laboratory, or corporate area with confidentiality obligations – the Guard-Dog is the professional complete solution for detecting prohibited or undesirable wireless devices in real-time.
What does Guard-Dog detect?
Guard-Dog monitors all common wireless protocols simultaneously:
- Mobile phones (2G, 3G, 4G LTE, 5G)
- Smartwatches & Wearables
- Tablets & Laptops (WLAN 2.4 GHz & 5 GHz)
- Bluetooth & BLE devices
- All RF and modulated voice, text, and data transmissions
As soon as a device actively transmits, Guard-Dog immediately raises an alarm – with a timestamp, device signature, and MAC address.
Self-sufficient, tamper-proof & ready to use immediately
Guard-Dog does not require a PC, network connection, or external software. It operates completely autonomously:
- Password- and key-protected touchscreen interface – no unauthorized access possible
- Fully configurable thresholds & alarm intensity
- Integrated backup battery with up to 4 hours of runtime
- Whitelist function for authorized devices – no false alarms from your own equipment
- Optional DF directional antennas for increased range
Range & detection performance
Guard-Dog detects active devices within a radius of approx. 40 meters. With optional DF directional antennas, the range increases to up to 75 meters – ideal for large halls, prison wings, or industrial areas.
Data protection & anonymity
Guard-Dog identifies devices, not people. No phone numbers, conversation content, or personal data are collected – only the time, device signature, and MAC address. This means the system can be used in compliance with GDPR.
