How to Use Different DIY Security Systems
Wired Security Systems
A
basic wired security system consists of cables or
wires, usually covered in PVC sheath, that run
through the walls and floors, a power source
connected to the main control panel, and a door
chime. Additional components include door and window
sensors, security and closed circuit television
cameras, flood sensors, and smoke detectors. Follow
these steps to install a basic wired system.
-
To install a wired system, mount
the sounder where you can hear it but where it
cannot be easily muffled or disabled by an
intruder. The sounder may be installed indoors
or outside in a protective metal box fitted with
a switch that will set off the sounder if
someone tampers with the box or sounder.
-
Mount the sounder’s backplate
first, but do not yet connect the sounder.
-
Mount door and window switches on
the doors and windows you wish to protect. Mount
the magnet to the door or window and the switch
on the frame so that they are close together
when the door or window is closed.
-
The system is connected with a
thin cord made of two wires. Loop an inch of
each exposed wire around a separate screw on the
switch or door cord.
-
Run the cord to the next switch
and repeat the process with the copper wire
only, connecting it to the window or door
switch’s screws.
-
Run the cord through the walls,
or along a baseboard, from the point farthest
from the sounder to the sounder’s backplate.
-
If the system calls for a
battery, decide on a location for them, such as
a cabinet or closet.
-
Connect the battery to the
sounder with the red and black bell wire
according to the system instructions.
-
Join the black battery wire to
the black sounder wire and the red battery wire
to the red sounder wire, going through the key
switch first if your system includes one.
-
Fasten the sounder to the
backplate and attach the wire between the
battery cells.
-
Test the system by turning on the
key switch and opening a door or window to make
sure the alarm sounds.
Wireless Security System
Wireless security systems consist of a control
panel, a keypad, a sound component, and a device for
alerting the authorities to a security breach.
Wireless systems may also include additional
components, such as motion sensors and window
sensors. Follow these steps to install a basic
wireless system.
-
To install a wireless system,
pick a location for the control panel near an
electrical outlet or near the main fuse box. If
your system will be monitored, choose a location
with access to a phone line.
-
Choose locations for the alarm
sounder and security sensors.
-
Drill a hole behind the control
panel location and below the electrical outlet
to connect the two and to avoid tampering.
-
Use the keypad to program the
features of your system according to the
manufacturer’s directions.
-
Install the alarm sounder near
another electrical outlet or in another location
if it is battery-operated.
-
Install the door and window
sensors by attaching a transmitter to the window
frame or doorjamb and a magnet to the window or
door.
-
Test the system by opening a door
or window and making sure the alarm sounds.
Budget DIY Security System
Homeowners may choose to create and install their
own
home security system or to customize an existing
wired or wireless system. Many homeowners find the
most cost-effective method is to purchase a security
system kit and add on additional components as
needed instead of purchasing each component
separately. The following components can be included
in a customized home security system. Follow the
basic instructions for wired or wireless systems to
integrate the components.
-
Door Sensors:
Door sensors sound when a door is opened. Alarms
may be set for 15 to 30 second delays to allow
the homeowner to enter the proper alarm code on
the keypad to disarm the system.
-
Motion Sensors:
Motion sensors are infrared sensors that detect
motion or the body heat given off by an
intruder. Motion sensors can be mounted indoors
or out and can be adjusted so they do not sound
when the motion or heat of animals under 85 to
100 pounds is detected. Many motion sensors are
battery operated and have their own chimes and
keypad, so they can be mounted anywhere and do
not have to be included in the initial system
installation.
-
Glass Break Sensors:
These may detect either the sound that glass
makes as it breaks or vibration sensors. Sensors
may be wired or wireless and are mounted to the
wall or ceiling near windows. One sensor per
room will detect the sound or vibration made
when glass is broken.
-
Window Sensors:
these are mounted to the window, frame, and
detect if a window is opened. The sensor may
operate by a magnetic connection between the two
parts or through passive infrared technology.
Sensors may be stand-alone detectors that have
their own sounder or may be part of your wired
or wireless system. Mount the window sensor six
to seven inches from the window’s bottom edge
and align it with the window frame component.
-
Indoor/Outdoor Sirens:
An indoor siren, or a sounder, is mounted on the
wall or ceiling where it can be heard easily.
The sounder will go off when one of the door or
window sensors is tripped and can be turned off
by entering the correct code in the control
panel keypad. An outdoor siren may be connected
to the indoor security system and is designed to
alert neighbors to an intruder. An outdoor siren
also may be wired to outdoor motion sensors.
-
Indoor/Outdoor Strobes:
These can include high-powered, motion-activated
colored lights that will turn on when an
intruder enters the protected area. They may be
stand-alone lights or tie into an indoor or
outdoor system. The lights may simply turn on or
may cause the siren to sound.
-
Surveillance Cameras:
Cameras may be wired or wireless and come in a
variety of sizes and shapes. Cameras may be
mounted indoors or out, usually near doors and
windows, and may be hidden or displayed. Bullet
cameras are compact, easily hidden, and can
record continuously or be triggered by motion.
Dome cameras are mounted on the ceiling, and
serve as deterrents. IP cameras are
closed-circuit television cameras with a
built-in web server that transmits images over
the internet. IP cameras can give live, wireless
surveillance access. Wireless cameras are
portable and easy to install and may function on
their own or as part of a larger system.
-
Flood Lights/Security Lights:
Security lights serve the dual purpose of
lighting the way into the house for the
homeowner and to deter intruders by illuminating
their entrance points. These lights can be
motion-activated or continuous. Security lights
are stand-alone features that can be added on to
the main security system.
-
Timed Lights: Flood or security
lights can be set to turn on and off at pre-set
times to illuminate the property at night.
-
Deadbolt:
Deadbolts may be single or double cylinder or a
keyless deadbolt. A single cylinder has a key
cylinder on one side of the lock and a knob at
the other. These are not suitable for mounting
near a window or decorative glass, which an
intruder may break to reach in and unlock the
inside knob. A double-cylinder deadbolt requires
keys on both sides and is more secure for doors
with breakable glass. Keyless deadbolts use
remote controls, keypads, or fingerprint
scanners instead of keys.
-
Window Track Locks:
These locks secure sliding windows and doors.
Install the lock on the window or door track and
mount a metal cup onto the sill. The bolt slides
between them and is secured by a key.
-
Peephole:
Install a peephole in front or backdoors to see
who or what is outside without opening the door.
Newer door viewers allow greater range of
vision, often to ground level. Drill a hole
through the door at eye-level, clean the hole
with a file or rasp, and screw in the peephole.
-
Dowels for Windows:
A cost-effective security solution for sliding
windows and doors. Simply cut a dowel to the
length of the track of a sliding window or door
and place it in the track.
-
Garage Door Controller:
These sensors close your garage door after a
specified amount of time to ensure it is not
accidentally left open. The sensor is mounted to
the wall inside the garage. Motion sensors may
be added to the garage for added security.
Pros and Cons
Wired security systems typically cost less than
wireless systems and are a good choice for those
building or remodeling their home or business,
because the system components must be included in
the building’s design. More complex wired systems
may need to be installed by a professional.
Wireless systems are more expensive than wired
systems, but do not require any invasive procedures
to install wires into existing walls. Wireless
systems are also easier for homeowners to install
themselves. Some wireless systems may experience
more false alarms, but this is debated among
security professionals. Customized and
self-installed systems offer the greatest
flexibility and can be added to or changed to suit
the homeowner’s changing needs.
DIY systems can be cheaper than comparable systems,
but additional add-on components can drive the price
upward. All systems should be installed carefully
according to the manufacturer’s instructions to
avoid false alarms and failure.
