Signal Detecting
Description:
VS123 is a video scanner and wireless camera for 900 MHz - 3.0 GHz,
5.0 - 6.0 GHz. It is a small device with built-in battery and
automatic scanning function. The detection range is 900MHz-6GHz,
and there are two rows of LED lights under the LCD screen. Mainly
for 1.2GHz 2.4Ghz5.8GHz image, VS-123 is a reduced version of
VS-125, using dry battery, the test distance is about 50 meters,
battery charging time can be used for about 1.5 hours in 6 hours.
Featured Function:
1. Install Battery
Battery compartment is located in the rear side. Remove the battery
cover, install AAA / UM-4 battery x 4 according to the + – indication, then put on the battery cover. This device is

2. Switch On
The power switch is located in the center of right side. Set at 1
to switch on, set at 0 to switch off.
3. Auto Scan
After switch on, this device will scan wireless video signal from
900 MHz to 6.0 GHz automatically. There are 2 rows LED displays
under the LCD screen.
1) The upper row is scanning band indication and battery low indication. Three blue LEDs indicate 1.2GHz - 2.4GHz - 5.8GHz
three frequency bands individually for user to know the scanning
status clearly. The LED at very right side is low battery warning
(Bat Low), it will go red when battery power runs down.
2) The lower row is indication of scanning and image lock. During scanning, the green LEDs will shuttle to-and-fro. When
receive video signal, user can lock the image, then green LED will
still.
4. Image Display
When detects wireless video signal, the image will display on
screen and the frequency of the image will appear in the left
bottom side of screen. The duration of image display on screen is
depended on the video signal strength, the stronger the longer.
This device keeps scanning, the image will fade away when scan to
other frequency and the screen will shut down to save power. When
detects next video signal, the screen will light up again to
display the image.
5. Lock Image
When detects significant image, press and hold the (+) button in left side over 1.5 seconds to lock the image. When hear

hear the audio, press and hold the (–) button in left side over 1.5
seconds to shift the audio frequency.
When hear beep once, the bottom of screen will appear L, it means
the frequency of audio demodulation is 6.5 MHz. Press and hold the
(–) button in left side over 1.5 seconds again, the audio
demodulation will shift to R, it means the frequency of audio
demodulation is 6.0 MHz.
Most of the audio of wireless video cameras are 6.0 and 6.5 MHz. If
you can not hear the audio both setting of L and R, the scanned
wireless camera might not have audio demodulation. Press and hold
the (–) button in left side, the audio demodulation will be
shifting between L and R (6.5 and 6.0 MHz) over every 1.5 seconds.
8.Unlock Image
After knowing the content of image clearly, press and hold the (+) button in left side over 1.5 seconds to unlock the image. When
hear beep once, the image is unlocked. The scan will continue and
