One-Way Remote Control Car Alarm with 3000-Metre Range and Mobile Phone Control

This one-way anti-theft alarm system is designed to provide reliable security for all types of automobiles, from standard cars to off-road modified vehicles. Its core function is to detect unauthorised access via vibration or sound and trigger a high-volume 115dB siren and light alarm within 0.1 seconds, alerting you from a distance. The system operates on a 12V DC power supply and comes with two remote controls, offering a substantial 3000-metre monitoring range for peace of mind. It incorporates FSK technology for stable signal transmission and includes features like anti-hijacking protection and a programmable automatic defence mode, making it a practical choice for enhancing vehicle security.

Features and Construction

This car alarm is built around a one-way communication system, meaning the remote sends signals to the vehicle unit but does not receive status updates back. Its construction and feature set are geared towards delivering a robust and responsive security alert.

Material and Build

The main alarm unit utilises a housing made from ABS plastic, a material chosen for its impact resistance and durability, which helps protect the internal electronics. Metal components are integrated for critical electrical connections and structural elements within the unit, ensuring reliable operation. The system is engineered to work in a wide range of environmental conditions, with the host unit rated for temperatures from -40°C to 80°C and the remote controls from -20°C to 60°C.

Size and Practical Fit

While specific physical dimensions for the unit are not detailed, its functional specifications define its practical application. The system draws a low static current (≤20mA for the host with a vibration sensor), minimising drain on the vehicle's 12V battery. The 3000-metre operational range provides extensive coverage, allowing the alarm to be effective in large car parks or from a significant distance. The inclusion of two remote controls adds convenience for multiple users.

Uses and Placement

This alarm is suited for anyone seeking an added layer of security for their vehicle, with specific functionalities that cater to different usage scenarios.

Event or Professional Use

For owners of off-road or modified vehicles often used in remote locations or at events, the long 3000-metre range and vibration sensing are particularly valuable. The optional GPS tracking function, if equipped, can provide location data, which is useful for recovery. The system’s robust temperature tolerance ensures it remains operational in harsh environments, from freezing cold to extreme heat.

Everyday Home Use

For daily commuter vehicles, the alarm offers a straightforward security upgrade. The high 115dB siren acts as a potent theft deterrent in residential areas or public car parks. Features like automatic window closing (where supported by the vehicle), central door lock automation, and the one-button start function via remote add everyday convenience alongside security.

Benefits and Buying Value

The value of this car alarm lies in its combination of long-range monitoring, rapid response, and a suite of practical, optional vehicle integration features.

Reuse and Low Maintenance

Once professionally installed, the system requires minimal ongoing maintenance. Its low power consumption in standby mode helps preserve your vehicle's battery. The durable ABS and metal construction is designed for long-term use inside a vehicle's cabin or engine bay. The provided remote controls are the primary interface, keeping daily operation simple.

Why Choose This Product

This alarm system stands out for its explicitly stated 3000-metre operational range and its 115dB alarm loudness, which are concrete, measurable security benefits. The support for optional features like GPS tracking, automatic window control, and anti-hijacking technology provides a path for customising security to your needs. It is presented as a compatible solution for "all automobiles," offering a broad application range without the need for model-specific variants.
