AK400 Portable Infrared Detector: 10MHz-5GHz Anti-Positioning and Anti-Camera Security Device
In environments where privacy is a concern, the AK400 portable infrared detector offers a practical solution for identifying unauthorised monitoring devices. This compact unit scans for signals across a broad 10MHz to 5GHz frequency range, covering many common camera, tracking, and positioning transmission bands. Weighing just 36 grams and measuring 91mm by 37mm by 13mm, it is designed for portability and discreet use in various settings, from professional spaces to personal environments. Powered through a standard 5V USB connection, it provides either audible or vibration alarm modes to alert users to potential surveillance threats within its 0.1 to 6 metre operational scope.
Features and Construction
The AK400 detector combines specific technical specifications with a user-oriented design to address modern surveillance concerns. Its construction centres on infrared detection technology tailored to identify electronic monitoring devices without complex setup.
Material and Build
Housing electronic components for signal processing, the detector is built to be lightweight and portable at 36 grams. The external casing accommodates the infrared sensors and alarm systems within its 91mm length, 37mm width, and 13mm depth profile. This material choice supports the device's primary function of being carried easily while maintaining the necessary internal circuitry for frequency analysis across the 10MHz to 5GHz band.
Size and Practical Fit
With overall dimensions of 91mm by 37mm by 13mm, the detector fits comfortably in a pocket or bag for transport. The 36g weight ensures it adds minimal bulk, making it suitable for regular use in different locations. The compact size does not compromise its detection range, which remains effective from 0.1 metres up to 6 metres from a potential signal source, allowing for thorough sweeps of rooms or personal spaces.
Uses and Placement
This detector is intended for scenarios where unauthorised recording, tracking, or video monitoring is a concern. Its specified purposes include anti-recording, anti-stealing, anti-video, anti-positioning, and anti-theft applications.
Event or Professional Use
For professional settings or sensitive meetings, the detector can be used to sweep conference rooms, private offices, or negotiation spaces for hidden cameras or positioning beacons. The 0.1 to 6 metre range allows methodical checking of walls, furniture, and fixtures, while the choice between audible and vibration alarm modes provides flexibility—audible for immediate group alerts or vibration for discreet personal notification during inspections.
Everyday Home Use
In residential environments, the portable design makes it straightforward to check guest rooms, rented accommodations, or personal studies for unwanted monitoring devices. The USB power option means it can be charged from common phone adapters, power banks, or laptop ports, facilitating use while travelling. Home users benefit from the broad 10MHz-5GHz frequency coverage, which includes many consumer-grade camera and tracking transmitter frequencies.
Benefits and Buying Value
The AK400 detector provides a focused tool for privacy protection without requiring specialised technical knowledge. Its value lies in its specific functionality and practical design parameters.
Reuse and Low Maintenance
As a reusable electronic device, it offers ongoing value through multiple checks over time. Maintenance is minimal due to the USB power system, which avoids proprietary batteries and allows charging from widely available sources. The simple two-alarm-mode operation (sound or vibration) reduces complexity, supporting repeated use in different situations without reconfiguration.
Why Choose This Product
This detector is suited for users seeking a dedicated device for anti-positioning, anti-monitoring, and anti-camera detection with clear, source-supported specifications. Its 10MHz-5GHz frequency band, 0.1-6m range, 36g weight, and 91x37x13mm dimensions provide concrete metrics for comparison. The inclusion of both audible and vibration alarms, plus USB power, addresses practical needs for flexibility and convenience in a portable security tool.
