Sirit has the largest install base of Title 21 compliant AVI systems in the world with installations in California (Orange County toll roads, San Francisco bridges, State Route 91, and I-15), Denver (E-470 toll road), South America and China. At the heart of Sirit’s AVI solution is the transponder or “tag”, a device that is placed on a motorist’s windshield to identify the vehicle. The tag communicates through Sirit’s antenna to a reader controller card which identifies the tag and transfers the information to the host management system. The IDentity T21 transponder can be read by the reader with an accuracy level in excess of 99.6% at vehicle speeds exceeding 100 miles per hour.From barrier-based to open highway application, IDentity T21 provides the highest performance, accuracy and reliability available.

In areas where toll transponders are used by even a small percentage of the traffic population, Sirit’s Traffic Management solution has proven to be an easily implemented and cost effective answer to monitoring commute time or traffic patterns. By deploying Sirit readers at multiple points along designated intervals of a toll highway or freeway, and by connecting those points by wire or wireless to a central host, travel time and traffic flow can be closely monitored in real time accumulating valuable data for traffic management or safety engineering.

Sirit’s IDentity Flex RFID reader is designed specifically for road segment monitoring across single or multiple lanes under all weather and traffic conditions. Using the latest generation radio frequency identification (RFID) technology and an embedded base of Caltrans Title 21 compatible toll transponders, accurate vehicle identification is reported to the host system using Sirit’s traffic probe protocol. This robust protocol was uniquely developed by Sirit to rapidly and accurately convey the tag identification, location of read point, time of read, and channel to the host controller. The protocol also includes an impressive array of diagnostic and monitoring features for testing or upgrading functionality.

Sirit’s IDentity Flex reader system uses Radio Frequency Identification (RFID) technology to read Sirit’s IDentity Flex and Title 21 vehicle mounted transponders. Mounted in a weather resistant NEMA enclosure, it is a self-contained versatile reader capable of stand-alone operation or interfacing with industry standard controllers.Sirit’s IDentity Flex reader’s unique ability to interface up to four antennas creates an economical solution for automatic vehicle access requirements. Quite simply, IDentity Flex offers the best price and performance of any system available today. No longer do you have to sacrifice convenience for security.

Sirit modules complement the core functionalities of these products by providing them with the ability to function as RFID readers / writers. The Company’s modules have been designed into and serve as the core RFID technology for a wide range of RFID offerings from tier-1 OEMs (including LXE, PSC, Psion-Teklogix, Handheld Products, AGFA, and Texas Instruments), as well as OEM channel partners / integrators.

Sirit offers a broad range of modules to support a myriad of RFID frequencies (UHF (902-928 MHz), HF (13.56 MHz), LF (125 / 134.2 kHz)), tag protocols (EPCglobal, ISO, proprietary flavors), data collection methods (RFID, barcode), and performance requirements, thereby enabling the Company to address a broad range of applications and market needs.
