LockCar Duo RH dual camera review, front and driver coverage with immobiliser
The LockCar Duo RH is the dual-camera local MCU system in the LockCar range. It provides simultaneous front-facing and driver-facing camera coverage, smart parking mode, local GPS tracking, and a hardwired relay immobiliser, all in one professionally installed system. This review explains who benefits most from the Duo RH and how it compares to the 4G Duo RH Plus.

The LockCar Duo RH is the dual-camera local MCU system in the LockCar range. It provides simultaneous front-facing and driver-facing camera coverage, smart parking mode, local GPS tracking, and a hardwired relay immobiliser, all in one professionally installed system. This review explains who benefits most from the Duo RH and how it compares to the 4G Duo RH Plus.
Duo RH specification and features
The LockCar Duo RH is a local MCU system, meaning it stores data and manages system functions onboard without requiring a 4G connection. It provides front-facing road coverage and driver-facing interior coverage simultaneously via two camera modules, recording both views continuously while in operation. Smart parking mode activates the cameras when the vehicle is stationary and the engine is off, recording incidents that occur while parked.
Local GPS tracking records route history and current position data, accessible when the vehicle is connected to the LockCar system. Unlike 4G GPS, local GPS does not transmit in real time to an external server. This means position data is available for review but does not trigger live push notifications to a remote smartphone. Power ON 24/7 ensures the system is always active regardless of whether the engine is running.
The relay immobiliser integrated into the Duo RH provides the same hardwired relay break as all LockCar dashcam systems. The immobiliser and dashcam share a power and control architecture, with the MCU managing both systems from a single unit. This simplifies installation and ensures both functions are always in the correct operating state.
Duo RH versus Duo RH Plus, which to choose
The decision between the Duo RH and Duo RH Plus comes down primarily to the requirement for real-time remote access. The Duo RH records and stores locally. The Duo RH Plus adds 4G connectivity for live camera streaming, real-time GPS push notifications, remote immobilisation via app, and cloud footage backup. If you need to monitor your vehicle from a remote location in real time, or want movement alerts to your phone, the Plus is required.
The Duo RH is the right choice for operators who primarily want dual-camera recording evidence and physical immobiliser protection without the ongoing costs of a 4G data connection. Fleet operators who review footage from a central location at the end of each working day, rather than monitoring in real time, will find the Duo RH meets their needs without the 4G connectivity overhead.
How LockCar stops this threat
LockCar installs a hardwired relay break in the vehicle start circuit. This break is positioned downstream of the factory immobiliser, the OBD port, and the CAN bus. Even after a successful relay attack or CAN bus injection, the engine will not start because the LockCar relay is open. Closing it requires a second, independent encrypted authentication that relay equipment cannot replicate. LockCar is designed and manufactured in the United Kingdom and installed by mobile engineers at your location.

How long does LockCar installation take?
Installation typically takes 60 to 90 minutes. Our mobile engineer brings all parts and equipment to your location. The system is fully tested before the engineer leaves and you receive documentation on the same day.
Will LockCar interfere with my vehicle factory electronics?
No. LockCar installation uses vehicle-specific wiring procedures and connects at the start circuit in a way that is invisible to the factory CAN bus, ECU, and all other electronic systems. All factory functions continue exactly as before.
Does LockCar cover my area?
LockCar mobile service covers the entire UK. Same-day and next-day appointments are available in most areas. WhatsApp or call Victor to confirm availability and book at your preferred location.
Can I get insurance documentation after fitting LockCar?
Yes. Every LockCar installation comes with a full certificate including device serial number, installation date, vehicle registration, and a technical description of the relay break mechanism. This is accepted by the majority of UK insurers for discount applications.
