L1-01D.17 – Pulse Count Detectors

Any signal that exceeds the threshold is considered a pulse. There is no qualification made as to the size and duration of the signal. A pulse count detector will indicate an alarm condition if a number of pulses (typically 2 or 3) are detected within a set time...

L1-01D.16 – Theshold Processing

Every PIR detector uses some sort of signal processing to determine if the pulses created by the PIR element indicate that motion is present. All PIR’s have a threshold to filter out background noise and signals created by minor temperature...

L1-01D.15 – Signal Processing Examples

DualCore: Signals are analyzed in multiple domains, including amplitude, time, frequency and duration C3: Correlates data from both channels simultaneously, instead of independently processing each MAP: Timing and sequence of signals are compared to settings for...

L1-01D.14 – Signal Processing

Signal processing is the mathematical analysis of the nature and characteristics of signals Goal is to block out “noise” that leads to false signals The difference between one detector and another is often the sophistication of the signal processing Check the...
