Learn more about Speed Displays

BT-Comm is used to connect to any Sierzega device in order to configure it and download traffic data.

GRS is used to process, analyse and display traffic data for Speed Displays.

This detailed manual includes information about setting up the device, connecting and configuring the device and analysing traffic data.

The GR33L is a dot-matrix display that is able to show speeds driven as well as individual bitmaps in either yellow or red, yellow and green. Its lightweight casing makes it perfect for mobile use.

It is a fact that radar-driven speed displays slow down traffic permanently.

This positive effect can be attributed to the display's ability to alert drivers with responsive messages wherever the device is deployed (school zones, Kindergarten, zebra crossings or on busy roads in residential areas).

The GR33L is a dot matrix display that is able to show speeds driven as well as individual bitmaps which is an additional benefit to common speed displays.

Additionally, the GR33L offers speed and time triggered bitmaps (such as smileys) and short text messages. For example, the device is able to show different pictures during school time and the rest of the day.

All these features are put into a compact and resilient enclosure.
