Questar Installer vs SmarTruckHD

Questar Installer App is the official mobile application designed for easy, fast, and reliable installation of Questar telematics devices in vehicles. The app enables validation of cellular communication, ignition, GPS, and CAN connections, and supports adding installer comments, selecting accessories, attaching photo documentation of the installation, and navigating to the vehicle by VIN or license plate (some features may not be available in earlier versions). With seamless integration into Questar’s cloud services, the installation process becomes transparent, automated, and fully ready for large-scale deployment by partners and customers worldwide.

SmarTruckHD is the companion app for SmarTruckHD radar sensors. Connect over Bluetooth to set up, fine-tune, and maintain your radar directly from your phone — no laptop or special cables required. KEY FEATURES • Scan & Connect — Find nearby SmarTruckHD radar sensors over Bluetooth Low Energy and connect in seconds. • Detection Zones — Configure the ignore area, warning area, and left/right detection width to match your vehicle. • Alarm Zones — Set the red, orange, yellow, and yellow-green distance zones for graded proximity alerts. • System Parameters — Adjust speaker volume, radar sensitivity, install height, trigger distance, trigger delay and interval, alarm-off delay, and working speed range. • Speed Limits — Define the minimum and maximum speed window in which the radar stays active. • Radar Self-Learning — Start the built-in learning routine to calibrate the sensor to its installed surroundings. • Factory Defaults — Restore the recommended configuration with one tap. • Device Info — Check the sensor's software and hardware version at a glance. • Metric & Imperial — Work in meters and km/h, or feet and mph. • Multilingual — Available in English, Chinese (Simplified), Spanish, and Italian. BUILT FOR INSTALLERS AND FLEETS Visual top-view and side-view diagrams show exactly which distance you are editing, so installers can configure a vehicle correctly on the first visit. All settings are read from and written to the sensor itself — nothing to sync, nothing to lose. NOTE This app requires SmarTruckHD radar hardware. It is a configuration tool and does not display live radar alerts. Bluetooth must be enabled on your phone.
