Your Safety, Our Priority
DETECTION SYSTEMS
Detection Systems are designed to warn the driver of impending 'danger', whether it's an obstacle that may damage the vehicle, or a Vulnerable Road User (VRU) that may have strayed into the vehicles path (or blind spot).
​
There are currently several types of sensor / detection technologies employed on vehicles, including:
​
-
Ultrasonic
-
Optical (electro-optical / video processing)
-
RADAR
-
LiDAR
Ultrasonic Sensors
Ultrasonic sensors work by emitting sound waves at a high frequency (i.e. 58kHz & above 18kHz), which is not audible. The sensors receive the reflected sound waves back, calculating distance based on the time taken. Due to the relatively small detection area, multiple sensors are utilised on vehicles (i.e. 4 sensors per side).
​
-
Short range (<2.5m)
-
Do not differentiate between moving and static objects (e.g. roadside furniture)
-
Susceptible to high levels of false detection / alarms by wind sheer, rain and dirt; also static object false alarms when utilised for side-scan/VRU detection (ADAC Test Report here)
-
Installation can be time consuming as multiple sensors are utilised and different sensor mounts may be required
-
'Low' cost
​
LiDAR (Light Imaging Detection and Ranging)
LiDAR sensors work by emitting light (laser) waves at a high frequency (not visible), they receive the reflected light waves back, calculating distance based on the time taken.
-
Long Range
-
Can be utilised to 'map' an area (for autonomous vehicles etc)
-
Can differentiate between moving and static objects
-
Reliable detection
-
'High' cost
RADAR (Radio Detection and Ranging)
RADAR sensors work by emitting radio waves at a high frequency (i.e. 24GHz & above 2GHz), they receive the reflected radio waves back, calculating distance based on the time taken.
​
​
-
Long Range
-
Can differentiate between moving and static objects (different types of RADAR)
-
Reliable detection
-
Can be a single unit, depending on application & beam pattern etc
-
'High' cost

** With additional equipment.
Cycle-Safe™ Optical Dection
Next generation optical detection technology combine detection and vision in single 'smart camera'.
​
The intelligent system provides drivers/operators with audible alerts and visual warnings, either via a monitor and/or a separate LED/buzzer.
​
Operators can choose whether the monitor is always on, or switched off above 20MPH. Audible warnings are enabled only when turning turning (indicating).
Unlike ultrasonic sensors, optical detection systems differentiates between moving (VRUs) and static objects, reducing driver workload/false alarms.
Optical detection systems can also be integrated with other cameras (including additional 'smart cameras'), sensors, alarms and DVRs.
Installation and Calibration
Installation is quick and easy, compared to multiple sensor systems. This is because the camera is also the detector. Additionally, no calibration is required.

How Ultrasonic Detection Works
Ultra-sonic sensors are designe to detect/static objects and are usually utilised at the front/front corners, or at the rear of the vehicle.
​
They are also used at the side of the vehicle, although this can mean that static objects create false alarms.
