AK400 Portable Infrared Detector for Anti-Positioning and Anti-Monitoring Alerts

This AK400 model portable infrared detector serves as a practical electronic alert device designed to identify potential surveillance and tracking activities within a specified range. It is engineered to detect signals across a broad frequency spectrum, providing users with an indication of nearby monitoring attempts. The device is compact and operates on standard USB power, making it suitable for personal security applications where concerns about unauthorised recording, video capture, positioning, or data theft are present. Its dual notification system allows for flexible use in different environments.

Features and Construction

The AK400 detector's functionality is defined by its measurable specifications and detection capabilities. It is a self-contained unit built for portability and straightforward operation, focusing on providing an alert rather than detailed signal analysis.

Material and Build

Specific construction materials for the housing and internal components are not detailed in the source information. The device's physical profile is defined by its dimensions of 91mm in length, 37mm in width, and 13mm in thickness, resulting in a slim form factor. With a total weight of 36 grams, it is lightweight enough for easy carrying. It incorporates an infrared detection system as its primary sensing method.

Size and Practical Fit

The compact size of 91mm by 37mm by 13mm allows the detector to be discreetly placed in a bag, pocket, or on a desk. Its 36-gram weight adds minimal bulk. The operational scope is defined as between 0.1 metres and 6 metres, setting clear boundaries for its effective detection range. This makes it suitable for monitoring a room, personal space, or immediate vicinity.

Uses and Placement

The detector is intended for scenarios where there is a desire to be alerted to potential electronic monitoring. Its applications are centred on personal security and privacy protection in various settings.

Event or Professional Use

In professional or sensitive meeting environments, the device can be used as a basic check for unauthorised recording or transmission devices within its 6-metre range. The vibration alarm mode allows for silent, discreet notification to the user without alerting others in the room. It serves a purpose for anti-theft of information in contexts where confidential discussions occur.

Everyday Home Use

For personal use at home or in private accommodations, the detector can provide peace of mind regarding potential hidden cameras or tracking devices. Its coverage from 10MHz to 5GHz aims to encompass common frequencies used by such devices. The audible alarm provides an immediate alert, while the USB power operation means it can be easily powered from a laptop, power bank, or wall adapter.

Benefits and Buying Value

The value of this detector lies in its specific function as an alert tool with defined technical parameters. It offers a focused solution based on its stated specifications.

Reuse and Low Maintenance

The device is designed for repeated use, powered by a standard 5V USB connection commonly available from multiple sources. No consumable parts or complex maintenance routines are indicated. Its simple interface—likely involving mode selection between sound and vibration—supports straightforward reuse without specialised training.

Why Choose This Product

This detector provides a concrete set of specifications: a 10MHz-5GHz detection band, a 0.1-6 metre range, and a choice of alarm modes. For users seeking a device with these particular alert capabilities and the portability offered by its 91mm x 37mm x 13mm size, it represents a defined technical tool. It addresses the practical need for a basic alert mechanism against the types of monitoring listed in its purpose.
