1 Introduction
Thank you for purchasing the AR-STV Wireless Camera Detector.
The AR-STV is a wireless camera receiver with a 2.5 inch color LCD display, still picture recorder
and sensor that captures analog video signals in real-time. It is mainly designed for use in
surveillance applications.
Its built-in clock allows images to be time-stamped and a (non-supplied) SD memory card can be
used to store images.

1-1 Maintaining the unit
There are no internal operator adjustments. In the unlikely event of service being required, please
contact your dealer for technical assistance.
Level of risk:
As the AR-STV operates with a 6 V DC power source, there is little chance of serious injury as long
as common sense is applied.
Observe the polarity of connections if using an external battery charger. DC input is a nominal 6V
DC, with the connector wired center conductor positive. Reverse polarity connection will damage the
AR-STV and could lead to the risk of fire or explosion under severe circumstances.
NEVER connect the AR-STV directly to the AC outlet.
Handling the AR-STV:
Use a soft, dry cloth to gently wipe the AR-STV clean. Never use abrasive cleaners or organic
solvents which may damage certain parts. Treat the unit with care, avoid spillage or leakage of
liquids into the cabinet and power supply. Special care should be taken to avoid liquid entering
around the keys, main dial or via the connectors.
[Note: Never push or knock the LCD screen – it is very fragile and sensitive to shock.]
Special remarks:
Do not use or leave the AR-STV in direct sunlight (especially the TFT display). It is best to avoid
locations where excessive heat, humidity, dust and vibration are expected. Always keep the AR-STV
free from dust and moisture.
1-2 Power requirements
The AR-STV is designed for operation from a nominal 6 V DC (4 AA size alkaline battery or Ni-MH
cells). The external 6V DC power supply may be used to charge the internal Ni-MH cells.
Do not use an external power supply when alkaline battery cells are in the unit.
[ Notice: Always disconnect the external power supply when in use.]

5 Operations of the AR-STV
To set or remove the key lock, press the blue button and FREQ.DOWN switch simultaneously.
5-1 Display
This section explains what you can expect to see on the AR-STV
LCD monitor screen.
Once the AR-STV is properly powered up, this display will
appear on the screen:
(1) 1G 2G 3G (Hz)
The horizontal axis displays the receive frequency. The AR-STV can receive between 900 MHz and
2800 MHz.
(1G indicates 1 GHz in frequency, 2 G for 2 GHz, and 3 G for 3 GHz accordingly.)
(2) V (Video level) N (Noise level)
Video Level
The V (Video) line on the vertical axis displays the video quality threshold level.
Note that video level is NOT related to the signal strength.
Setting the video threshold level higher will display the video signal only with the better quality.
Setting the video threshold level lower will display the video signal even if it is of poor quality.
Noise Level
The N (Noise) line on the vertical axis displays the signal strength.
Setting the Noise threshold level higher can detect only strong signals.
Setting the Noise threshold level lower can detect any weak signals even of poor quality.
Video Level and Noise level can be adjusted on the Search Bank Setting Menu.
5-2 Operation Mode
There are three (3) operation modes with the AR-STV.
Search Mode
Memory Mode
Setting Mode
5-2-1 Search Mode
This is a default operation mode of the AR-STV. On this mode, the AR-STV will search frequencies
between 900 MHz ~ 2.8 GHz (2800 MHz) continuously until signal is detected.
Once the AR-STV detects the signal, it will automatically
switch the screen to display the received video signal.
To stop searching, press the FREQ switch inward. Then
the screen on the right will appear.
