Countersurveillance Bug Detector - Spy Cam Detector
Product Description
|
Ultra-Sensitive Countersurveillance bug detector instrument that detects and displays electromagnetic radiation over a broad spectrum of frequencies. The ZC 185 is a quality instrument that detects and displays RF (Radio Frequency) signal levels with uniquely high sensitivity, similar to a broadband receiver. It provides Linear and Logarithmic measurements of RF signals over a broad span of frequencies. The ZC 185 allows the user to detect and measure signal strength and to distinguish between analog and digital transmissions. 1. Security personnel concerned with
detecting and installing surveillance equipment.
2. Wireless installers and RF
engineers - to optimize hub sites, detect hot & dead spots, plotting

levels of transmitted radiation for health and environment reasons.
5. Aircraft/Utilities flight crews
and maintenance personnel to detect radiating devices that could affect
flight safety and communications.
Uses for the detectot measures electromagnetic radiation from 3 MHz to 5 GHz. This includes a variety of household devices:

FEATURES1.)
Simultaneous detection of RF transmitted signals over a wide
spectrum of frequencies spanning from 3 MHz to over 5 GHz, including
cellular phones and wireless phones, FM, TV and short wave broadcasts,
computer wireless devices, wireless security systems, microwave ovens, ham
radio, police and service bands, and transmitting surveillance and spying
devices such as hidden cameras, transmitting bugs and covert video or data
transmissions. 2.)
Very high sensitivity with the ability to detect signals from
wireless devices, cellular phones and covert bugs at more than 50+ feet,
transmissions from sealed microwave ovens at 40+ feet, from
walkie-talkies at 100+ feet, and from amateur radio transceivers at
hundreds of feet. 3.)
Detection and differentiation between analog RF signals and digital
transmissions. Enhances
the detection of cell phones, wireless phones and computer wireless
signals. 4.)
Wide dynamic range display in the LOG (logarithmic) mode covering a
1000 to 1 input signal range, as well as a highly sensitive LINEAR mode
where only the weak signals are examined. A MID mode is used for detection
and measurement of intermediately strong RF signals 5)
Input signal strengths in the LOG mode, MID mode, and LINEAR mode
are adjustable by using a sensitivity controller. 6)
RF field strengths displayed on both an analog meter and colored
Light-Emitting Diode (LED) displays. The LED display produces better
readability from a distance and in dim light such as
nighttime. 7)
A silent vibrator mode allowing the instrument to be used to detect
radiated RF signals (as from a hidden camera or body bugs) without being
observed. The silent vibrator mode is independently switched ON or
OFF. 8) Fixed internal antennas which do not require any adjustments and give repeatable signal strength readings.

GETTING TO KNOW THE ZC
185
|
1. METER DISPLAYThe analog meter gives a reading of radio frequency signal strength. It provides a clearer visual display of rapid signal changes than other types of displays. 2. LEDs
Two Light Emitting Diodes (LEDs) are
used to give a signal strength indication for viewing at a distance or in
low light conditions. The LED display directly correlates with the analog
meter readings. The green LED illuminates brightly with little or no meter
reading and progressively dims as the meter reading becomes stronger. The
red LED begins to illuminate at moderate meter readings and progressively
gets brighter at stronger signal levels. 3. SILENT VIBRATOR
SWITCH The silent-vibrator switch turns the silent vibrator mode ON or OFF. 4. LOG-MID-LINEAR SWITCH
In the LOG (logarithmic) mode the detector senses a large dynamic range of signal strengths. It excels at pinpointing the location of signal sources without overloading the ZC 185 measurements. In the LINEAR mode the detector is at its most sensitive operating mode, allowing it to detect weak signals at a far distance. The MID (middle) mode is a combination of LOG and LINEAR modes allowing the instrument to detect moderate RF signals with an expanded dynamic range of signal strengths. 5. OFF-SENSITIVITY
CONTROL
The ON-OFF switch for the instrument is coupled with the SENSITIVITY control. The sensitivity control adjusts the amplification of the ZC 185 over a 10 to 1 signal range (20dB). 6. ANALOG DIGITAL SWITCH Continuous Radio Frequency signals are detected in the Analog mode. The Digital mode is used when the transmitting device is broadcasting digital or rapidly pulsed analog signals. Digital signals are distinguished from analog signals when measurements in the digital mode are noted to be stronger than in the analog mode. 7. The rear battery door allows access to the battery compartment that holds two (2) AA batteries. Alkaline batteries are recommended. (Rechargeable batteries do not work). 8. FREE STANDING DESIGN
The flattened bottom enables the instrument to be placed upright on its end allowing the meter display and LED displays to be visible from a distance. |

1. INITIAL
SETTINGS Initial conditions of the ZC 185 should be with the LOG-LINEAR switch in the LINEAR mode, the Vibrator switch turned OFF, and the Analog-Digital switch in the Digital position. Turn on the ZC
185 by rotating the OFF-SENSITIVITY control to the
right. 2. SETTING THE BASELINE, AMBIENT
SIGNAL LEVEL Initially switch
to the LINEAR mode for long distance detection of weak RF
signals. Rotate the
OFF-SENSITIVITY control from low to high to adjust the sensitivity of the
instrument so that the ambient, baseline RF Signal level reads between 10
to 40 on the meter scale. This is a measure of the baseline signal level
at that particular location. 3. USING THE DIFFERENT AMPLIFICATION
MODES A detected weak
signals will present as an increase above the ambient signal level reading
in the LINEAR mode. The far-away weakest signals are detected
here. The MID mode is
used for detection and measurement of moderate signal
levels. Switch to LOG mode
for localizing and pinpointing the signal source when the transmitted
signal reading is too high on the meter scale in the LINEAR and MID
modes. The signal source is
localized exactly in the LOG mode without overwhelming the meter
capabilities. 4.
LOCALIZATION Generally, to determine the location of a transmitting device, move in the direction which increases the signal strength on the ZC 185. As the signal strength increases and the meter reading becomes maximized, switch from LINEAR to MID mode and finally to LOG mode to get to a readable part of the meter scale. The highest reading in the LOG mode is just adjacent to the signal source. 5. SILENT VIBRATOR
MODE The silent vibrator is used when it is difficult to view the displays or when it is desirable not to be noticed when monitoring the RF signal strength. Once a threshold level is exceeded the vibrator turns on and operates in a pulsating manner. The strength of the vibrations increases with an increase in RF field strength, making it easier to locate the signal source without viewing the display. 6. ANALOG DIGITAL
MODES A continuously broadcasting signal can be measured in either the Analog or Digital modes. When the signal is digital (i.e., it is pulsed on and off at a rapid rate), it gives a relatively low reading in the Analog mode, but measures accurately higher in the Digital mode. This is due to the pulsing of the RF signal. If the signal is rapidly pulsed on and off, the meter display will register an average signal reading of the on and off pulse times in the Analog mode. In Digital mode the pulses are detected as peak-signals which register a higher reading than the average of on and off pulses measured in the Analog mode. |
