ETECTORS
Camera EYE-02 integrates a wide range of detectors. This sophisticated solution combining various
types of detectors enables the user to protect the desired area from a wide range of points of view.
This chapter briefly describes individual detector’s principles necessary for correct setting of
detection.
PIR
MOTION DETECTOR
(PIR)
PIR detector or a Human Body Detector is the most common type of professional security systems
detectors. PIR can detect even very small changes of temperature differences in front of the camera.

ICTURE DETECTOR
(MIP)
The key principle of this detector is derived from a professional surveillance camera system – DSP
(digital signal processor).It permanently analyzes the scene and can detect any change in picture.
A sophisticated digital algorithm provides a very good resistance to false alarms caused by non-
essential changes in pictures (getting dark, switching on the street lamps, etc).
A user can simply mask a part of a picture not to detect changes in this part (mask of street traffic)
and set the sensitivity according to the size and velocity of change in picture.
As the DSP method is energy demanding, MIP is usually activated after some alert from SOUND or
PIR detector.
N
OISE DETECTOR
(SOUND)
Noise detector uses a microphone to check the surrounding for any sound above the preset level.
Sensitive electronic filtering can detect the air pressure changes – this principle allows detection of
door or window opening at a long distance.

BREAK DETECTOR
(GBS)
Glass-break detector uses digital analysis of sound from the microphone and is able to detect a
characteristic sound of breaking a window up to 9 meters away.
The Door-Opening-Detection is a special type of detection which use the acoustic signal filtering. It
allows to detect the infrasonic wave (pressure wave) caused by door or window opening.
GBS sensor might be used for indoor installation only.
T
ILT A VIBRATION DETECTOR
(TILT)
Built-in tilt and vibration detector can detect an unwanted manipulation with the camera, e.g.
stealing the camera body or changing camera position.
As a vibration detector is very sensitive it should not be use for outdoor installation to prevent the
false alarms caused by a blow of wind.
Note: The detectors are optimized to application in rooms with max dimension up-to 10meters.
