Systems System equipment and programs Sensors for transport
Transport identification/registration
For transport registration we offer – UHF RFID stickers for windshield, active and passive RFID cards and license plate visual recognition. The system we offer ensures 92-98% quality. Contactless readers and identifiers can be used with over 1m radius. Distance between reader and identifier significantly increases registration process.

For people and vehicle real time locating system (RTLS) we offer low power transmitters (Active UHF) placed on vehicles. These can be used, for example, for a timetable and transport registration and control system. Compared to GPS systems, this system also works indoors and in bad weather.

Video cameras with image processing software (VideoAnalytics) make it possible to identify cars, people and objects, which sometimes prove to be a very effective solution.

Transport sensors
There are various vehicle sensors with different technologies. These sensors can be used in parking lots or on the roads.

The equipment we offer uses the following technologies:
  • Infrared barriers (people and vehicles);
  • Inductive loops under the road surface (vehicles);
  • Laser, infrared, microwave and ultrasonic sensors (vehicles);
  • Camcorders with image processing software (people and vehicles);
  • Geomagnetic sensors (only for vacant parking spots).
The offered sensors may be integrated with any system, particularly with FidPark. Reports are available as digits or graphs. You can find more information here.

Electronic car signs are affixed to the car or placed behind the windshield and are automatically read before the checkpoint, barrier, or boundary of the designated area. The driver can identify while both inside and outside the vehicle.

Automatic plate number recognition (APNR) technology is integrated into the access control system, supplementing or completely replacing the car electronic tags.

RTLS
We offer low power real-time locating system (
RTLS). RTLS works great for a timetable and transport registration and control system. Compared to GPS systems, this system also may work indoor and in bad weather conditions.

Infrared barriers
 Infrared barriers commonly consist of two components - the light source and the detector. These may both be in the same place, or placed across from each other.
  • Across - the detector is activated whenever something obstructs the illumination from the light source;
  • In the same place - the detector is activated when light from the light source is reflected from a target.

Inductive loops under the road surface
An inductive loop system consists of loop detectors and inductive loops that are embedded in a road pavement and connected to a control box. The loop may be excited by a signal ranging in frequency from 10 kHz to 200 kHz. When a vehicle passes over or rests on the loop, the inductance of the loop is reduced and this change is detected by the loop detector and is signaled to the control box.

Laser, infrared, microwave and ultrasonic sensors
Laser sensors send an intense light impulse to a defined location and measures the time until the signal returns, thus determining the distance to the object. By analyzing this information, sensors can determine the exact location, speed, and location of an object in a short period of time.
Products: Opening & safety sensor for barriers

Radar or microwave sensors emit microwaves with certain frequency in a defined area. These microwaves are reflected back to the sensor by all objects in its environment. Sensors are able to detect whether an object is moving and what direction it is moving.

Infrared sensors emit infrared light in a well-defined area and analyzes the reflections that come back. There are two types of infrared sensors:
  • With background analysis: analyzes background and is triggered if there is any significant difference when compared to the original picture.
  • With background suppression: analyzes the distance between sensor and object. It is mostly used when the background is likely to change (e.g. sensor is fixed on a moving door panel).
Ultrasonic detectors operate by transmitting ultrasonic energy and measuring the energy reflected by the target. These measurements are processed to obtain the object presence and speed. Ultrasonic detectors work perfectly well in any weather conditions.
