Planning Your Camera Location; Testing The System - Radio Shack 49-2513 Owner's Manual

PLANNING YOUR
CAMERA LOCATION
When you choose a location and posi-
tion for the camera, take into account
how the motion sensor operates. A
passive infrared system operates by
sensing body heat or the difference
between a person's body heat and a
nearby building or a wall.
When the temperature of the moving
body and its surrounding area are
close in value, detection is more diffi-
cult. The motion detector's infrared
beams radiate outward like the slats of
a wooden fence.
Motion that crosses these "slats" acti-
vates the detection circuit. Motion
which parallels the slats might not. For
the best results, position the camera
so expected motion cuts across the
slats.

Also, if sound is important to you,
choose a location so sound near the
camera is picked up by the built-in mi-
crophone. (for example, located at
your front door). For a better viewing
angle, position the camera above eye-
level and pointing down. Avoid view-
ing areas where half the area is in
bright sunlight and the other half is
dark.
Important Sound Note: Do not install
the camera or the distribution box so
either of their built-in microphones are
near or point directly toward the
speaker of your TV or monitor. Other-
wise, you might get audio feedback (a
squealing sound) which will interfere
with the sound source when you use
the button on either the distribu-
TALK
tion box or camera.

Testing the System

Before you permanently mount all the
components (monitor, camera, distri-
bution box, and remote motion alarm)
in their proposed locations, we recom-
mend you test them as a system.
