Fig. 3.8 SAFE-BAG plugin: appearance and (a) and the view with the cover removed (b, c)
stationary phone and switch it to the tapping mode. Integrated activated location
control function makes this plugin a perfect means of anti-theft and personal protection. It can also be used for simple management in the sphere of cargo transportation.
The range of the motion sensor is approximately 7 m with viewing angle of 160°.
The plugin is equipped with two sensors. The passive infrared motion detector
responds to movement of people entering the controlled area without authorization.
In addition, the microphone picks up noises in the relevant area, which means that
before taking further measures, you can listen to what is happening in the tapped
room. Before notifying the user about the events using an SMS message, the device
performs double assessment of the situation in order to prevent false alarms.
The range of the motion sensor is about 7 m. The aperture angle in the horizontal
plane is 160°, while the hemispherical Fresnel lens mounted on the module ensures
partial focusing of heat radiation. Infrared detectors respond to heat radiation of
human body, the intensity of which is about 1 W per 1 kg of body weight. Regardless
of the fact that human body is covered with clothes, these sensors are sensitive
enough to ensure reliable detection within the specified range. By the way, it will
bring no results if the intruder starts moving slowly in order to trick the electronics.
