Stalker’s VMS trailers are powered by Precision Solar Controls and deliver pre-programmed and customizable messages in addition to monitoring vehicle speeds.
Full Matrix, Pulse Width Modulation
At the heartof the Stalker VMS is Precision Solar Control’s Full Matrix, Pulse Width Modulation LED Design. The Full Matrix LED Design treats all of the pixels in the display as a continuous image. This allows the pixels to be controlled individually to create various sizes of alphanumeric characters and display graphic images.
LED Pulse Width Modulation significantly increases the time between battery charges and powers the LEDs so that they remain at a consistent brightness despite the normal voltage drop during the batteries’ discharge cycle.
2-year warranty on trailer/sign and radar, 1-year warranty on the battery.
Message Library of 60 standard messages with a 350 message capacity on 365-day calendar controlled by a dedicated on-board computer. A full-size QWERTY keyboard expedites setup and message modification in the field.
On-board dedicated computer 
provides NTCIP compliant programming on 365-day calendar for ease of use and maximum customizability.
4’ x 8’ display
(44” x 84”viewing area) ensures legibility at up to 1000 feet for greater motorist compliance and safety while efficient, 10-year-average-operational-life LEDs reduce maintenance time and expense.
Graffiti-resistant paint keeps the trailer looking clean and neat for a professional department image, while its all steel construction provides a sturdy platform and reduces damage sustained in the field.
4D deep-cyc
le 12-volt batteries provide up to 24 days of continuous operation yielding longer operational time between battery charges.
Optional Equipment
Top-mounted solar panel recharges a day’s worth of battery use with only 4 hours of sunlight allowing for “infinite” field operation.
Stalker Traffic Speed Sensor Ka-Band Doppler Radar
The speed measurement component is pure Stalker - accurate and durable.
Stalker’s Ka-Band radar has greater range, sensitivity, and tracking compared to competitive signs’ K-Band radars.
Integrated statistical package gathers valuable traffic data for improved grant writing support and verification of the sign’s impact on traffic speeds.
