Introduction
Thank you for selecting the Guardian Angel. This highly configurable
wireless audio/visual monitoring system allows you to set up a monitor-
ing network quickly and easily without the need to install wires and
cables.
Included in this wireless system are a full-color CMOS camera/transmit-
ter and a portable hand-held receiver with a color TFT LCD display.
Both units can be powered by the built-in rechargeable lithium-ion
batteries or by the included power adapters, which also serve as battery
rechargers.
Standard RF transmission protocols, built-in rechargeable batteries,
selectable operating channels and standard A/V input and output ports
provide a wide range of applications.
In addition to video and audio monitoring capabilities, the Guardian
Angel can also function as a wireless audio/visual or home theatre hub,
linking VCRs, DVD players, televisions and stereos. Users can watch
TV or DVD movies on the handheld receiver or on a television screen in
a different room or area of the building.
The Guardian Angel supports up to four separate transmitters operating
on separate channels that you can switch between using a single hand-
held receiver.
Features
• Wireless audio and video monitoring for office security
• Connects to standard audio/video input and output ports of devices
including VCRs, DVD players, televisions and personal computers
• Lightweight receiver is equipped with a 2.5-inch color TFT LCD
screen and built-in speaker
• 2.4 GHz signal avoids interference from 900 MHz cordless phones
• Adjustable antenna transmits up to 300 feet (FCC - USA)
• Four-channel capability allows a single receiver to receive signals
from up to four different transmitters

Setting Up the Guardian Angel
Setting Up the Camera/Transmitter
This chapter takes you through the steps required to set up the Guardian
Angel. Depending on the model you purchased, your Guardian Angel
will come equipped with either a fixed mounting bracket or a tripod. For
instructions on setting up the tripod, see the next section, “Attaching the
Camera to the Tripod” on page 6. For instructions on setting up the fixed
mounting bracket, see “Assembling the Fixed Mounting Bracket” on
page 8.

Setting Up the Tripod
Attaching the Camera to the Tripod
1. Hold the camera firmly to avoid dropping it.
2. Screw the threaded top of the assembled angle bracket clockwise
into the hole on the underside of the camera body.
Positioning the Tripod
The camera tripod is equipped with adjustable legs to allow positioning
of the camera at a range of heights. Each of the three legs is individually
adjustable to allow compensation for uneven surfaces. The camera
mount angle bracket at the top of the tripod can be adjusted to a suitable
angle by loosening the angle bracket screw, setting the angle, and then
tightening the screw.

Take the following points into consideration when planning a location
for your camera:
• The camera should be positioned so that the view of the area to be
monitored is unobstructed.
• The line of sight between the camera and the video monitor should
be as clear as possible. Reducing the number of doors, walls and
windows between the camera and the video monitor improves recep-
tion quality.
• Decide if you want to power the camera using the included power
adapter, or using the built-in rechargeable battery. If you operate the
camera with the power adapter you must ensure that there is a power
outlet nearby.
When positioning the camera:
1. Make sure the camera is securely attached to the tripod.
2. Position the tripod in the desired location, adjusting the legs and
angle as necessary.
3. Test the reception of the video monitor/receiver in locations where
you plan to use the receiver. See the section “Adjusting Reception
Quality” on page 25 for information on improving wireless trans-
mission quality.

Setting Up the Fixed Mounting Bracket
Assembling the Fixed Mounting Bracket
The fixed mounting bracket included consists of three parts:
• Angle bracket
•Stem
• Base mount
Follow these steps to assemble the fixed mounting bracket:
1. Screw the threaded end of the stem clockwise into the base mount.
2. Screw the threaded end of the angle bracket clockwise into the top
of the stem.

Attaching the Camera to the Angle Bracket
1. Hold the camera firmly to avoid dropping it.
2. Screw the threaded top of the assembled angle bracket clockwise
into the hole on the underside of the camera body.
Attaching the Mounting Bracket to a Fixed Surface
You may choose to attach the camera mount to a fixed surface such as a
wall or ceiling; however, the following points should be taken into
consideration when planning a location.
• The camera should be positioned so that the view of the area to be
monitored is unobstructed.
• The line of sight between the camera and the video monitor should
be as clear as possible. Reducing the number of doors, walls and
windows between the camera and the video monitor improves recep-
tion quality.
• Decide if you want to power the camera using the included power
adapter, or using the built-in rechargeable battery. If you operate the
camera with the power adapter you must ensure that there is a power
outlet nearby.

To mount the camera to a fixed surface:
1. Make sure the mounting assembly components are screwed
together firmly.
2. Hold the base of the mount against the fixed surface and point the
camera at the area to be monitored.
3. Have another person test reception of the video monitor/receiver in
locations where you plan to use the receiver. See the section
“Adjusting Reception Quality” on page 25 for information on
improving wireless transmission quality. Determine the optimum
camera placement before proceeding to the next step.
4. Using a sharpened pencil, mark the location of the three mounting
bracket holes on the fixed surface (e.g. wall).
5. Drill three holes at the locations you marked.
6. Push the wall plugs into the holes.
7. Use a Phillips screwdriver to screw the base mount to the fixed
surface.
8. Attach the camera to the angle bracket and make final adjustments
to the camera angle. Tighten the angle bracket thumb screw as
shown below.

Using the Rechargeable Batteries
The rechargeable batteries included with the Guardian Angel provide
convenient, cable-free power to both the transmitter and receiver.
Normal operating times are as follows:
Operating time is maximized when the receiver is set to receive audio
only. The receiver can also be plugged into an electrical outlet using the
power adapter as explained in the following section.
When the batteries no longer contain enough charge to power the
receiver or transmitter they will automatically shut down. There is no
audible or visual warning prior to shutdown.
Caution:
• Incorrectly replacing the batteries may result in explosion.
• Replace batteries with the same or equivalent type of battery.
Never force the pins of a power adapter into an electric outlet. Purchase
a plug adapter if necessary.
