CCTV with Video Analytics Video analytics is unable to perform its duty in changing environments. Its performance is hindered by shadows, reflections and glare. Bright light conditions, wet and dusty weather also affect its efficiency. Although video analytics work continuously all year round, they need constant maintenance as lenses have to be cleaned on average every 3 months.

Thermal Cameras with Video Analytics Outdoor conditions are not ideal for thermal cameras. During the day, darker objects can absorb the sun’s energy and heat up, an effect known as thermal loading. When objects in the scene become uniformly hot in any given area, many cameras have difficulty presenting the narrow range of temperature differences into a useful image.

Infrared Sensors Infrared sensors work on the principle of reflected light waves. Infrared light reflected from objects or sent from an infrared remote or beacon. Infrared sensors are used to measure distance or proximity. The reflected light is detected and then an estimate of distance is calculated between sensor and object.

Inductive Loops Loops are limited by certain conditions. As an example, if one vehicle passes over the loop but is being tailgated by another vehicle, the sensor may have a false reading and record a multi-axle vehicle in stead of two individual ones. Depending on the number of lanes on a motorway, more than one loop may be required, therefore making it more expensive to install.

Pneumatic Road Tubing The system works well for short duration counts on lower volume roads, however it is ineffective when it comes to high vehicle density roads and multi-lane highways. If two vehicles cross the tube at the same time, then the direction can’t be accurately determined. Also if two cars cross the tubes close together, the system may see them as one multi-axle vehicle and give a false reading.

Piezoelectric Sensor Although Piezoeletric sensors are more accurate at counting traffic than the Inductive Loops, their accuracy and reliability is still limited. A very crude classification is performed by accessing the pressure down on ground, which can be subject to environmental conditions. It is also affected by variance in speed which gives false readings.

Doppler Radar Microwave Commonly applied for measuring speed, Doppler Radar technology relies on emitting a microwave signal, which when reflected back to the sensor the speed is calculated. ClearWay uses a Frequency Modulated Continuous Wave (FMCW). Target speed is calculated from successive observations, within the software, as such there is no requirement for Doppler processing. This improves the processing performance, and provides more accurate data.
