DETECTOR
OF SHF - FIELD DP - 04, DP - 21
|
|
DP-
04 frequency range
25÷3200 MHz
|
The
detector allows finding out transmitting interceptors
as well as measuring the relative level of electromagnetic
radiation from household and industrial devices:
•
mobiles;
•
microwave stoves;
•
medical equipment;
•
radio modems of the ISM range;
•
other transmitting apparatus.
ADVANTAGES
•
High sensitivity (<1.5 mV);
•
Detection of radiation of any modulation and coding type
(noise-like signals, abrupt frequency switching, etc.);
•
The set includes methodical recommendations on searching
for interceptors (DP-4);
•
Microprocessor control (DP-21);
•
The detector has acoustic feedback;
•
Low cost, small overall size and simplicity of application.
|
|
DP-
21 frequency range
2÷100 GHz
|
Indication
of the signal level:
•
A light-emitting diode 10-segment logarithmic scale;
•
An interrupted sound signal of changing tonality.
Organs
of control:
•
A sensitivity control handle;
•
A power supple switch;
•
Volume control;
•
An operating conditions switch.
Power
supply:
•
Two cells or accumulators of the standard size "AA".
WATCHDOG "DRUZHOK" -
AN ELECTRONIC TOY WITH GUARD FUNCTIONS FOR ADULTS
According
to the data of the Ministry of Internal Affairs and independent
guard service, the dog is the most efficient and available
means of preventing crime against private property. A
poll of the "gentlemen of fortune" specializing
in flat burglary conducted in the places of confinement
has also supported the fact that, in most cases, barking
behind the door makes them abandon their criminal intentions.
An electronic
watchdog "Druzhok" is good at guarding.
It is a
soft toy with a movement detector inside which includes
a sound signal in the form of barking when an object moves
in front of its muzzle. "Druzhok" responds to
the movement of ob-jects outside the door, window or in
a neighbor room, if they are within the guard range of
its action, and produces a sound signal of regulated volume.
The detection
range of a moving object is no less than 3 meters, the
supply voltage is 12 V, the consumption current in the
guard condition does not exceed 0.2 A and in operation
- no more than 0.5 A.
