Experts in Human, Vehicle & Object Detection
IEE has been developing sensor solutions for over 30 years. These sensors have been utilised in the automotive, health and smart buildings sectors. Their experience has led them to build reliable and accurate devices that customers can rely on.
IEE’s Tailgate Detector TDflex™ offers a unique solution that ensures only authorised people can enter a restricted area of any building. By combining TDflex with a new or existing access control system, customers can be sure they’re maintaining safety for their visitors, employees and infrastructure.
Today’s access control systems are designed to help control and manage authorised access to secure areas. Ensuring that every individual has properly presented a valid ID, or successfully cleared biometric identification is a major challenge faced by security professionals. Preventing tailgating and piggybacking, in other words misleading or outsmarting the system, is a problem existing solutions do not sufficiently address. With IEE’s TDflex™, businesses can optimise the scheduling of their security staff. As the sensor is fully automated, security staff don’t need to physically monitor access points;they will be alerted if there is a security breach.
How does it work?
IEE has developed a 3D sensor that uses MLI (Modulated Light Intensity) technology. This technology is based on the optical time of flight (TOF) principle, where an active, non-scanning light source emits modulated near infra-red light.
The phase shift between the light emitted by the source, and the light reflected by the people and objects in the field of view, is measured to create a real-time topographic image of the monitored area. The 3D MLI Sensor™ calculates the exact number of people transiting the detection area, and triggers an alarm when it detects situations such as tailgating or piggybacking.
