TCR-SLI GEN2 Datasheet


TCR-SLI is a solar powered radar object counter with integrated LoRaWAN® connectivity.

The system shared_content powerful radar signal processing that enables bi-directional counting of moving objects in distances up to 10m. Objects can be categorized into up to 4 groups with speed and object size filters. Counter values are transmitted in regular intervals to the LNS (LoRaWAN® Network Server).

TCR GEN2 is a very versatile radar counting system. It enables various applications such as people counting, traffic statistics, use of sports facilities or even security applications.

TCR-Sxx types come with an integrated solar charging unit including tempered battery. The battery is used to backup up to 4 foggy days. The system can be installed very flexible on different locations including remote areas without any electricity.

Technical Specification

Note: This technical specs relates to Firmware 2.2

Side Mounting

When mounted sidewise, TCR can detect objects passing by in both directions

IMPORTANT: Minimum distance to street or path should be more than 50cm

IMPORTANT: If a bigger object hides a smaller object behind it, it will be counted as one.

Wall mounting


The device can be mounted at a pole at around 3m facing towards the street. Our pole mount MT80-15 (accessory) can be used for that. This is useful in public places to prevent damage from vandalism.

Power Sources

It is possible to operate the unit either with a solar cell or an external 12V power source such as a 12V battery or DC Power Supply. Mixed operation is also possible, with automatic switching.


Please select a small solar module that does not exceed the following power rating. Higher voltages can destroy the internal solar charger. We offer solar modules with 9W or 17W power, which have been tested with the device. (Ask for SOL9-KIT or SOL_17-KIT)
