Rear Traffic Alert Warns Officer Rear Traffic Alert, a proprietary new feature of the 2X, is designed to warn the patrol officer of rapidly overtaking same-lane traffic. Rear Traffic Alert is active when the patrol vehicle is most vulnerable to rear-end collisions--pulling into traffic from a standing start. If the 2X senses a rapidly approaching vehicle within adjustable speed parameters, it prompts the officer with a distinctive alert tone and displays ALE rt in the strong and fast windows. Rear Traffic Alert is only available on the 2X and is a patent pending Stalker technology. 4 Target Zones in Stationary Mode; and 2 Target Zones in Moving Mode Conventional moving radar can only monitor traffic in one Target Zone. Now, with the introduction of the Stalker DSR 2X, two moving Target Zones or all four stationary Target Zones can be monitored simultaneously. Stalker DSR 2X is actually two independent radar units operating on a single display. In moving mode, two Target Zones can be simultaneously monitored - one front Target Zone and one rear Target Zone. In stationary mode, all four Target Zones can be simultaneously monitored. The direction arrows indicate target direction for both the front and the rear display windows. Or, if desired, only one front Target Zone and one rear Target Zone can be simultaneously monitored. Measure closing targets while automatically ignoring vehicles that are going away - even if a target moving away is closer than a distant closing target. Automatic Same Lane Operation Provides Voice Verification of the Location, Radar Mode, and Direction True Doppler Audio • Rear Traffic Alert Warning • Simultaneously Measures 2 to 4 Targets • VSS Patrol Speed Mode • Direction Sensing Technology • Automatic Same-Lane Tracking • Stationary Direction Control (Closing, Going Away, or Both) • Strongest & Faster Targets Are Simultaneously Displayed • Strongest & Faster Targets Can Be Individually Locked • Voice Verification of Locked Targets • Stop Watch Mode • RFI Immune Digital Antennas • Backlit, Cordless IR Remote • Detachable, Multi-Colored Display • True Waterproof Antennas • True Audio Doppler Tones • Digital Signal Processing • Microstrip Antenna Design • Software Controlled and Upgradeable View the Strongest and Fastest Targets Simultaneously By displaying both strongest and fastest targets simultaneously, the Stalker DSR can monitor faster vehicles passing larger vehicles and display the speed of both targets simultaneously. The Stalker DSR utilizes three colors (red, amber, and green) to differentiate between the strongest, fastest, and patrol speeds. Small Display / Counting Unit The compact display and counting unit is small enough to be mounted almost anywhere. If an even smaller unit is desired, the display / counting unit can be separated and then just the display can be mounted on the dash. Waterproof Ka Band Antennas The Stalker DSR 2X includes two O-ring sealed, ultra-high frequency, Ka band antennas. These compact, completely waterproof antennas utilize locking, waterproof connectors and can be exterior mounted with no reliability concerns.
