Introduction
TCR are solar powered radar object counters with integrated LoRaWAN®
connectivity.
The system includes 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.
Installation
To achieve the most accurate measurement possible, planning the installation is
essential. This chapter therefore contains information on the correct choice of
location for the TCR traffic counter.

Horizontal or Top Down?
The devices can be operated both directly next to the road or elevated and looking
down from above. We recommend using a laser measuring tool or a laser pointer to
align the device correctly.

Page 2: Important Rules
Important Rules The device works best when the following rules are observed. Lateral to movement__ TCR are side radars that detect motion from both directions simultaneously. The movement should be linear. Therefore place the sensor parallel to the movements direction and keep away from curves,... - Page 3 LTR vs RTL The TCR traffic counters distinguish between 2 directions. RTL = objects which come from the right and disappear to the left. The left LED will pulse once in this case. LTR = objects which come from the left and disappear to the right. The right LED will pulse once in this case.

If the uplinks fail, the counter will be reset to zero after this time. Default: 120min Totalizer This setting defines how to increment the counter values.

Page 14: Device Profile
Usually device profiles are saved once during the production of the devices. E.g. TCR-DLI/LS/EU868 However starting with TCR GEN2 and Firmware V2.1, both the Speed Class as well as the LoRaWAN® Region may be changed by the user too. This allows to stock standard types (TCR-DLI, TCR-DLE, TCR-SLI, TCR-SLE) and configure it later according to customers need. - Page 15 This should return the device's SKU, TCR-xxx/LS/xxxxx or TCR-xxx/HS/xxxxx Changing LoRaWAN® Region The integrated LoRaWAN® modem in TCR GEN2 devices can be adapted to LoRaWAN® frequency plans used in different regions. A complete list of countries can be found in the LoRaWAN® 1.0.3 Regional Parameters Document.
