This detection system is much more precise, avoiding the incessant switching on and off that passive infrared (PIR) detectors do.
This system is ideal for environments where people sit for long periods, such as on your garden terrace in the evening. What's more, HF detectors are insensitive to pollutants, unlike passive infrared detectors which lose sensitivity if the lens gets dirty.
The twilight switch-on setting is preset at the factory to an appropriate outdoor light threshold, and the timer is set for 30 seconds, so there's no need for the user to make any adjustments.
Microwaves or hyper-frequencies are electromagnetic waves of intermediate frequency between infrared and radio waves.
They are called SHF (Super High Frequency between 3 and 30 GHz) and UHF (Ultra High Frequency from 300 MHz to 3 GHz).
as in mobile phones and wireless networks (Bluetooth, Wi-Fi, DECT, Wi-Max, local wireless video transmitters for baby monitoring, antenna-free TV, microwave ovens, etc.).
The ultra-precise sensor only detects movement and is influenced by four factors:
- the size of the object (intruder)
- its distance from the detector
- its speed of movement
- its angle of approach.
The searchlight will only switch off if there is no movement in its search field.
Conclusion:
- Greater detection stability
- Greater adaptability to difficult environments
- Greater accuracy of detection field
