The Beltronics STiR Plus Radar-Laser-Safety-Detector is an Installed High Performance Stealth Defense System. The STiR Plus is an updated version of the STiR Concealed Radar Detector and adds some new features while retaining those of the original STiR system.

The Beltronics STi-R-PLUS is designed to be invisible inside and out. A powerful radar/laser antenna mounts under the hood of your vehicle. Small control and display modules and an amplified speaker can be mounted anywhere inside the vehicle. By installing these components in discreet locations, you can achieve an invisible installation.

The STiR Plus also utilizes the new TotalShield™ Technology, allowing it to be completely invisible to any type of radar detector detector (RDD). Police use RDDs to locate vehicles that are using radar detectors. The STiR Plus produces no signal leakage, meaning it cannot be detected by any current or future RDDs.

The STiR Plus uses multiple laser sensors to constantly search for laser gun signals. The AutoScan™ feature of the STiR Plus eliminates the need to shift between city and highway modes, and virtually eliminates false alarms. It also supports the detection of "POP" mode radar.

The Beltronics STiR Plus also provides a sophisticated high definition text display and clear digital voice messages for easy recognition of alerts. Four brightness levels are supported on the display, including Full Dark Mode, and an “auto” mode which automatically adjusts the brightness of the display depending on the amount of ambient light in the vehicle. The display offers three meter display modes and can be easily viewed from almost any angle.

Other features include a Pre-Loaded Safety Camera DEFENDER™ Database with information to warn you on thousands of red light and fixed position speed camera locations across The US. (includes three years of downloadable updates). The STiR Plus is also Web Ready. You can connect it to your Windows XP, Vista or Windows 7 computer for easy updates from Beltronics' web site.

These are just a few of the many features of the powerful Beltronics STiR Plus stealth installed radar detector. If you are a professional driver looking for serious performance and a truly invisible radar detector, this is the model for you!


Professional installation required.

Display and Control Modules

The only parts of the Bel STiR Plus stealth installed radar detector that need to remain within reach of the driver are the small display and control modules, along with the external speaker. Each of these modules is 2 inches wide by 5/8 inch tall, and the speaker is 2 1/4 inches square. Any of these components can be mounted anywhere - allowing you to have a clean, discreet installation.
