The 8504D Digital Shock, Tilt, and Temperature Sensor is an add-on security sensor designed for DS4 and DS4+ systems. It adds an extra layer of protection by detecting impact and vibration, sensing vehicle tilt (such as jacking or tow attempts), and monitoring temperature to support automatic remote start when conditions are too hot or too cold. It connects via D2D 2.0 for a clean, integrated install and can be tuned to match the vehicle and customer sensitivity preferences.

D2D 2.0 Compatibility

The 8504D connects through D2D 2.0 for clean integration with compatible DS4 and DS4+ systems.

Digital Shock and Tilt Detection

The fully adjustable digital shock and tilt combo sensor helps detect impact, vibration, lift, and tow activity.

Warn Away and Full Trigger Responses

Two-stage response helps separate light impacts from confirmed events, with Warn Away and Full Trigger alarm responses.

Adjustable Tilt Sensitivity

Tilt angle sensitivity can be adjusted from 1 to 3 degrees to help detect jacking, lifting, or towing attempts.

15-Level Shock Adjustment

Shock sensitivity can be adjusted across 15 levels to help dial in performance for the vehicle and installation.

Built-In Temperature Sensor

The integrated temperature sensor supports automatic remote start when outside temperatures are too hot or too cold.
