FAQ Operation ​
Counting is not as expected. What can I do?
Distance to object
LS-Devices: The sensor must be placed at least 50cm away from the target.
HS-Devices: The sensor must be placed at least 3m away from the target.
Avoid obstacles in FOV
Make sure there are no obstacles such as walls, street signs, shrubberies, trees in the field of view. When placed beside water the device might detect the waves.
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, crossings, driveways.
for more help, please check the Installation Instructions
Why are some detected objects missing from the data?
- Check the Installation Instructions to see if the device is installed correctly (parallel to the movement, no obstacles etc.).
- Check if Confirmed Uplinks are enabled to avoid data loss.
- Review LoRaWAN network conditions (high sensor density can cause interference).
How can I verify detection accuracy manually?
Use the PMX Setup Tool to compare real-time detection with physical observations. A manual count can help verify accuracy.
Unexplained counts during the night?
This can happen when there is a thunderstorm or even animals that only appear at night.
DC power is not reported correctly
Voltage measurement is limited to 0-6.6V when using the external DC input, even if you apply 12V DC. This is a known issue on all hardware revisions (00, 01, 02, 03, 04, 05) and will be fixed in the next release.
This limitation does not affect solar powered units as the voltage measurement is managed by the charger chip.
