1 Introduction
1-1Introduction
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, steel 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 an optional 1 GB SD memory card can be used to store
up to nearly 2000 images.

1-2Maintaining 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.
1-3Power requirements
The AR-STV is designed for operation from a nominal 6 V DC (4 AA size alkaline battery or Ni-MH cells). An
external 6V DC power supply (not included), which should be capable of supplying a minimum of 1 amp
continuous 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.]

4 DC 6V (External power input connector)
To charge the internal Ni-MH cells, connect a 6 V DC charger into this connector. Note
that the center pin of the jack is positive.
5 SD (SD memory card slot)
Insert a SD memory card (up to 4 GB) into this slot to save images.
Approx. 2,000 images may be saved on a 1GB SD card.
Before using a SD memory card, it must be formatted (FAT 32) by a PC.
6 ALM OUT (Alarm output connector)
Connect an external alarm device into this connector. (3.5 mm stereo)
Pin assignment of the connector:
Tip --- Beep output and alarm output
Ring --- Relay output (this pin will make a short circuit to the ground for 2
seconds after a video signal is detected)
(Relay specifications: 50 V DC, 150 mA max. )
Sleeve --- Ground

3 Connections
Connect the supplied flexible rubber antenna to the SMA antenna connector on the top of
the AR-STV.
If required, an external antenna may be connected with a SMA connector for the coaxial cable.
Insert the supplied 4 AA size Ni-MH cells into the battery compartment in the AR-STV.
If not fully charged, connect an external battery charge into the DC 6V connector.
4. Power switch
To switch on the AR-STV, slide the power switch on the right side of the AR-STV upward.
4-1 Start-up
After inserting the batteries, switch on the power switch. The LCD displays search screen
and a STA (Status) LED will blink indicating the AR-STV is in the search mode.
4-2 Powering down
To switch off the AR-STV, slide down the power switch.
4-3 Low Battery
When internal battery voltage becomes low, the Low Battery indicator will appear on the LCD screen. In the
meantime, a beep will sound.
When this message appears on the screen, all operations of the AR-STV will quit
automatically. Immediately switch off the AR-STV, and replace all internal battery cells with
new ones or charge batteries with an external charger.
5 Operations of the AR-STV
5-1 Display
6

This section explains what you can expect to see on the AR-STV LCD monitor screen.
Once the AR-STV is properly powered up, the 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 ~ 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 it has a 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 it has a 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
7

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, then it will automatically switch the screen to display the received
video signal.
To stop searching, press the FREQ switch inward. Then above screen will appear.
