The SIR sensor, the smart detection device
The SIR sensors automatically adjusts light intensity according to the presence or absence of people, cyclists or slow moving cars.
When there’s no activity, the lighting is lowered to a chosen dimmed level.
The slightest movement:
- Activates immediate restoration of lighting intensity by sending a priority command to the LED driver (adjustable level and duration).
- Sends detection information to light points equipped with SIR Wireless detectors, NOD receivers or VIA relays, ensuring instantaneous wireless communication via secure LoRa point to point protocol.
A key component in the SensyCIty ecosystem, the SensyCity ecosystem, this detection sensor maximizes energy savings and preserves safety and night-time environment.
The SensyCity application allows you to set up to 5 dimming levels per nightenlever.
The NOD receiver, the gateway between detection and remote management
The NOD receives radio detection information from a SIR detector or a VIA relay. It instantly restores lighting intensity on receipt of the information by sending a priority command to the LED driver (adjustable level and duration). This enables dynamic management of street lighting according to the activity detected in the area. Integrated into a Tegis ecosystem, it can also be transformed into a remote management node positioned directly on the street lighting pole.
The VIA relay, a gateway to the intelligent city
The VIA relay links various city functions with the SensyCity detection ecosystem in order to adjust and optimize street lighting based on various types of information. It recovers activation information from sensors such as vehicle radar, traffic or weather sensors, then uses a dry contact input to send it instantly by RF communication to light points equipped with NOD receivers or SIR Wireless detectors.
The VIA relay boosts communication securely and instantaneously. It acts as a signal repeater, enabling greater distances to be covered without loss of communication quality.
The version integrating a DALI output can also control the light point on which it is installed by sending a priority command to the LED driver (level and duration adjustable with the SensyCity application).
SRM radar detector, performance and precision
Available in light vehicle or pedestrian versions, the high-tech SRM radar uses the Fizeau Doppler principle at a frequency of 24.125 Ghz, combined with a high-performance microcontroller.
Thanks to this very high frequency and extreme miniaturization, the SRM radar achieves exceptional performance in a compact, waterproof housing.
Its mounting system, specially designed for public lighting masts, enables easy fixing and multiaxial orientation of the radar.
The SRM radar is to be used with the VIA relay to interface with the SensyCity ecosystem.
SIR accessories to customize your detection zone
The expertise developed from hundreds of SensyCity installations has enabled us to design a range of accessories to adapt the detection zone to all field configurations encountered.
Positioned directly on the SIR sensor, the accessories can be used to adjust the PIR sensor’s detection zone to best meet your detection needs.
They can be installed when the detection system is first commissioned, or following the emergence of a more restricted zoning requirement.
SensyCity modules add great value to modern infrastructures by enabling flexible, intelligent and eco-responsible local lighting management. Their ease of installation and maintenance simplifies deployment while guaranteeing lasting efficiency. They combine lower energy costs, improved user safety and reduced light pollution.
