Wireless Signal Detector Anti-Theft Travel Monitor with Pinhole Lens Detection ABS Plastic 85mm 350mAh Battery Alarm Security Device
Wireless Signal Detector for Travel Anti-Theft Security with 350mAh Battery

This wireless signal detector is designed to help you feel more secure when away from home, providing a practical solution for monitoring hotel rooms or any unfamiliar environment. The device uses vibration induction technology that triggers a powerful audible alarm instantly upon any sudden shock or movement, effectively deterring potential intruders. With a compact, lightweight ABS plastic construction, it fits easily into luggage or a handbag, making it a convenient companion for frequent travellers. The built-in 350 mAh rechargeable battery offers continuous operation for 8 to 10 hours, with a fast charging time of just 1 to 2 hours, ensuring it is ready when you need it. This detector combines simple functionality with reliable performance in a portable form factor.
Features and Construction

The detector is built around a straightforward yet effective alarm system that prioritises ease of use and portability. Its durable ABS plastic housing protects the internal components while keeping the overall weight low, ideal for on-the-go use. The device measures 85 by 40 by 10 mm, making it small enough to leave on a bedside table or attach to a door handle without being obtrusive.
Vibration Induction Alarm
The core feature is the vibration induction sensor, which activates a loud alarm when the device experiences a sudden shock or knock. This immediate response is intended to scare off thieves and alert you to any tampering, providing a simple but effective layer of security. The alarm sound is powerful enough to be heard in a typical room, giving you confidence that you will be notified of any disturbance.
Rechargeable Battery and Power
Powered by a 350 mAh lithium battery, the unit can run continuously for 8 to 10 hours on a full charge. The operating current is only 30 mA, contributing to efficient energy use. Recharging takes between 1 and 2 hours via the included charging cable, minimising downtime and allowing you to use the detector repeatedly over multiple trips.
Compact and Lightweight Design
The ABS plastic body and small footprint make this detector easy to slip into a pocket, backpack, or travel case. Its modest dimensions mean it does not take up valuable space, and the simple design means no complicated setup – just place it where needed and switch it on. The colour is a single, neutral style that blends into most environments.
Uses and Placement

This security device is versatile enough for various settings where basic motion or vibration detection is desired. It is especially practical for travel but can also be used in other scenarios where a simple alarm is helpful. The lack of complex controls makes it accessible for anyone, regardless of technical experience.
Hotel and Accommodation Security
When staying in hotels or rented rooms, place the detector on a door or window handle. Any attempt to open the door from outside will cause a shock that triggers the alarm, giving you an early warning. It can also be placed on a desk or shelf to detect if items are moved while you are out.
Everyday Home Use
At home, the device can be temporarily used on drawers, cupboards, or doors where you want an extra alert. It is not a permanent security system but provides an affordable, movable option for short-term needs. Its small size means it can be stored away easily when not in use.
Benefits and Buying Value

This detector offers straightforward security with minimal maintenance requirements. The rechargeable battery eliminates the need for disposable batteries, saving cost over time. The ABS plastic construction is simple to wipe clean, and the device requires no specialist installation, making it a practical choice for anyone wanting basic protection while travelling.
Reuse and Low Maintenance
The battery can be recharged hundreds of times, and the charging cycle is quick, meaning the device is ready to go again soon after use. No ongoing costs for batteries or complex upkeep are needed; occasional cleaning of the exterior with a damp cloth is sufficient. The built-in alarm is self-contained and does not require replacement parts.
Why Choose This Product
If you need a simple, no-fuss alarm that can protect your belongings or alert you to movement while away from home, this detector provides a focused solution. Its emphasis on portability and ease of use makes it suitable for travellers, students living in shared accommodation, or anyone wanting an extra layer of security in a small package. The combination of vibration induction, long battery life, and compact form factor addresses a common need without unnecessary complexity.
