OHD900 specifications

The Directed Electronics OHD900 is a sophisticated vehicle security system designed to provide comprehensive protection for automobiles. This system utilizes advanced technologies and features to enhance the security and convenience of vehicle owners.

One of the standout characteristics of the OHD900 is its two-way remote communication system which allows users to receive real-time alerts from the vehicle. This feature ensures that users can monitor their vehicle's security status from a distance, providing peace of mind in various situations. The remote also includes a range of up to a mile, facilitating easier communication even when the vehicle is parked far away.

The OHD900 is equipped with a range of security measures that include a Shock Sensor, which detects impacts and vibrations, triggering an alarm if necessary. This sensor is particularly valuable in deterring potential thieves, as it can sense unauthorized entries or break-ins. Additionally, the system features a built-in duress code capability that allows users to disable the alarm discreetly in case of a threatening situation, adding an extra layer of safety for users.

Another notable feature of the OHD900 is its ignition kill switch. This technology immobilizes the vehicle if an unauthorized access attempt is detected, thereby thwarting would-be thieves from driving away with the car. This feature works seamlessly with the vehicle’s existing ignition system to offer an effective form of protection.

Moreover, the OHD900 supports smartphone integration, enabling users to interact with their vehicle's security system via a dedicated mobile app. This functionality provides enhanced convenience, as it allows users to remotely lock or unlock their vehicle, track location, and monitor the security status, all from their smartphones.

The system is also designed with ease of installation in mind, featuring a straightforward wiring harness that simplifies the setup process. This feature makes it an attractive choice for both professional installers and do-it-yourself enthusiasts looking to enhance their vehicle's security.

In conclusion, the Directed Electronics OHD900 promises a robust security solution for vehicle owners through its innovative technology, convenience-driven features, and effective protective measures. Equip your vehicle with the OHD900 to enjoy peace of mind no matter where you park.
