Détection de présence
Nod Presence Sensor
A 24 GHz radar that knows when someone is there, without a camera.
Le défi
Motion sensors miss people who keep still, and cameras are not welcome everywhere.
Nod Presence Sensor
Ordinary PIR sensors only see movement, and cameras raise privacy questions. Nod uses a 24 GHz radar to sense a person present up to 16 m away, and the distance and speed of a moving person up to 25 m, without capturing any images.

Où l'utiliser
Keeper safety checks
Know whether a person is still in a service area or empty enclosure before it is locked.
After-hours intrusion
Presence alerts in restricted zones when nobody should be there.
Rooms & corridors
Occupancy for lights, fans and room use, with no camera.
Ce qu’il fait
Presence
Whether a person is there, up to 16 m, including someone standing or sitting still.
Distance & speed
In ranging mode, how far (1.2–25 m) and how fast (0.1–10 m/s) a person moves.
Wide view
A 100° × 40° beam that tilts ±30° on its hinge to aim it.
Your detection zone
Set the minimum and maximum range, trigger distance, sensitivity and hold time.
Behind covers
Works behind plastic or glass panels; metal blocks it.
Not a people counter
It reports presence and one target's distance and speed, not a headcount.
Comment ça marche
Place
Stand Nod on a shelf or fix it to a tripod or camera mount, and tilt it at the area to watch.
Set
Choose the detection range, trigger distance and sensitivity.
Use
It reports presence, or distance and speed, to your system.
Pourquoi les équipes le choisissent
Sees people who keep still
Radar presence, not just movement.
Private by design
No camera and no images.
Aim it where it matters
Tilts ±30° and works to the zone you set.
Simple to place
Desk, shelf or tripod thread, powered over USB-C.
