5. Home Security Basics
Home Security Systems are a great asset for homes
throughout the world.
Benefits provided include:
Preventing theft, vandalism, and destruction of property by
providing valuable video of any motion that has occurred.
Interior and Exterior CCTV Cameras can be used to
monitor
and record video of the nanny, babysitter, workers,
care givers, or children inside the home.
Let’s take a look at the basic components
6. Interior & Exterior CCTV Cameras
Give the ability to watch
your family property and
business from just
about anywhere.
Indoor Home CCTV Cameras provide coverage of the inside
the home.
Outdoor cameras are the same in terms of styles, sizes and
shapes.
Outdoor cameras are weather-proof while addressing low
light conditions
* CCTV stands for Closed Circuit Tele-Vision, and is a system of
security cameras all linked to one monitoring system.

CCTV Security
Cameras come in
several different
varieties.
How do they work?
Dome CCTV Cameras, Covert CCTV, and Security Spy
Cameras.
9. How Do CCTV Cameras Work?
CCTV Cameras come in varying types:
Indoor or Outdoor
Wired or Wireless
Analog or Digital
What are the basics?
10. How Do CCTV Cameras Work?
Basics are the same: A camera, a lens, a
monitor, and
the cables (for wired systems) to carry the signal
from
point A to point B
Some systems use video recorders to record the
images
The camera picks up the signal being
monitored via the lens which can sometimes
be purchased separately from the body (like a
DSLR)
Anything else I should know?
11. How Do CCTV Cameras Work?
In a wired system the camera sends the signal via
a
coaxial cable to the Monitor/DVR/Computer
System
Wireless Systems tend to use computers as
monitors so you can view images from anywhere
including the internet
What about the cameras sensors?
12. What is CCD and CMOS?
Instead of film, a digital camera has a sensor that
converts light
into electrical charges.
The image sensor is called a “Charged Coupled Device”
(CCD) or CMOS (Complementary Metal Oxide
Semiconductor).
CCD sensors create high-quality, low-noise images.

13. What is CCD and CMOS?
CMOS sensors provide high resolution but their high
light sensitivity are generally more susceptible to
noise.
CMOS sensors traditionally consume less power than
CCD
Many current CCTV security cameras with CMOS sensors
use
IR cut-filters to help reduce noise levels.
You can use both types depending on what you want to
achieve.

A CCD image sensor
14. What Do You Need?
For recording purposes your customer will
need:
1. DVR for the digital systems.
The DVR can receive, record, and store
information
for later viewing.
A VCR - video recorder for an analog system.
2. CTV cameras to capture the images and
information.
3. A quality monitor to view real time and recorded
images.

15. Dome Cameras
Typically domes are the best choice whenever
possible.
Domes cannot be easily reached, manipulated, or
vandalized.
Domes install easily in drop ceilings – usually 2
screws.
Since a dome has a covered lens the direction the
camera is pointing is hidden.
Domes can accommodate infra-red for Night Vision.
16. Box Cameras
Use when mounting to a wall or any vertical area.
When viewing long distances where a long lens is required,
which would not fit inside a dome or bullet camera.
When extreme low light conditions are not a consideration.
Place in a protective enclosure if the box camera is within someone’s
reach.
17. Covert or Spy Cameras
These are meant not to be seen and come in all shapes and sizes
from
a wall clock to a sprinkler head or smoke detector.
NOTE: It is important customers check with local laws in respect to
covert recordings. In some states certain types of covert cameras
are illegal.
Pin hole camera
18. Infrared Cameras
For low light situations total darkness then the only possibility is
an infra-red camera or otherwise known as night-vision.
The distances infra-red cameras can see are based upon its
illumination capacity.
Note:
Infrareds have a limited life since they are illuminating so they do burn out
over time
19. Bullet Cameras
Typically small while the type of internal boards and lens is limited.
Bullet cameras picture quality cannot compare with other more
traditional cameras, which can have double layer boards and
camera function controls.
Use when you want the camera to be inconspicuous but not covert.
When the camera is not within someone’s reach.
When extreme low light conditions are not a consideration.
For shorter to middle distances.
20. Pan Tilt Zoom (PTZ) Cameras
PTZ cameras are used when you want live control of the camera
and adjusting the manual pan, tilt, or zoom on a fixed cameras is
not practical.
When you want to set up a camera to tour the premises.
When you want to view several angles from a single camera.

21. What Is a DVR and Why Do I Need It?
A DVR (digital video recorder) records and plays back motion
video in a digital format to a hard disk.
DVR technology is the basis of video surveillance systems.
Video from a DVR can be easily stored and reproduced.
A PC configured as a DVR, like a surveillance system, commonly
uses one
or more cameras for a video source.
22. Multiplexers
Multiplexers take multiple camera signals and combines them
onto one.
Now you can record them on a recording system of your choice making it
easier
to manage being it works with the DVR to put all recordings in one place.
Choose a multiplexer based on the number of camera inputs you
need.
Possible features and benefits can include:
23. Multiplexers
An alarm output, should suspicious activity take place.
Time and date stamp, so you know when any recorded activity
took place.
Motion detection, so you get the most out of your recording.
Some can be used with computer software.
With computer setup, multiplexers allow for remote access.
Can be used with either color or black and white cameras.
Simultaneous playback and recording when connecting two
DVRs.
24. Wireless Camera Systems
When connection to the
digital video recorder is not
practical
Wireless is just for the video
signal, you still need a
method to power the
camera.
Wireless cameras can be
found in most styles.
For the most part wireless
cameras require a line-of-
sight to function properly.
Distances will vary depending
upon the strength of the
transmitter and receiver
25. Stand Alone Systems
Standalone Systems are a great choice for
easy installation of a Home CCTV Camera
System.
The Standalone DVR plugs directly into
any standard television over a standard
RCA Cable, and allows you to view live or
pre-recorded video right to the TV.
An option for plugging into your DSL
or Cable internet connection to view your
cameras over the internet using a web
browser.
26. Home Security On-Line
What is the Benefit of CCTV ONLINE:
By using CCTV consumers can monitor, record, and store all
forms of activity using smart phones, tablets, laptop, or PC in real
time from anywhere.
The online setup can also function as an alarm, a siren sound will
blast on your computer or Auto Dialing your phone number.
Note:
The DVR must be connected to a router in order to monitor remotely of from a
smart phone.
27. PC Based Home Security Systems
This is a great choice for Home CCTV Cameras where
high-quality recording and remote viewing is necessary.
Watch your Home/Business via CCTV Cameras and
record them right to your PC.
View your Home CCTV Cameras right over the internet
from a PC, Laptop, tablet, or cell phone.
Simply insert the PCI card and connect cameras while using the
PC hard drive (or external) for storing data.
28. Bundled Kit Systems
DVR and Camera Security System features up to 16 total
channels(and more) to accommodate large scale surveillance
applications.
Kits include color cameras and sometimes decoy cameras to
deter theft.
The also have pre installed hard drives to archive footage
for instant access at a later date.
The DVR and Camera Security System supports mobile phone
remote surveillance for monitoring property
H.264 compression maximizes available space for maximum
footage possible.

33. Quick Glossary of Terms
A.L.C. (Automatic level Control) – Allows the auto iris circuitry to either
take bright spots (peak light) into consideration so it can bring out the
detail in bright areas.
Attenuation – A decrease or loss in signal. Reduction of signal
magnitude(loss)
is normally measured in decibels

simultaneously displays them over one monitor
Notas do Editor
NOTE: While dome cameras are the installation choice there are limitations. As the domes themselves are typically small you are limited in the size lens available. If you need to focus on long distances which requires a lens of 50mm focal length or greater it will not fit inside a standard dome camera. Dome cameras can be simple plastic ones or metal vandal-proof for public places.
NOTE: If the box camera is within someone’s reach the camera is usually inserted in a protective enclosure. If the lighting is extremely low box cameras can be inserted inside enclosures that have built-in infra-red illuminators but the camera must be infra-red sensitive. Meaning it is able to utilize the infra-red illuminators from an external source.
Note: For example, in New York State you are not allowed to install smoke detector cameras. With respect to recording audio, there are very specific laws, which vary from state to state. Some states require all parties consent to recording, while others only require a single individual.
NOTE: The distances infra-red cameras can see are based upon its illumination capacity. Infra-red cameras have LED’s, which cast out into the darkness. Realistically, a good rule of thumb (but not an absolute) is figure 1 foot for each LED. Therefore, if a camera has 30 LED’s then it probably can see about 30 feet. There are some newer LED’s called Cat’s Eyes, which have more power, but they are not very common. You would notice a Cat’s Eye by the extra large size of the LED’s. With respect to infrared quality it has more to do with the intensity of the LED's and the distance they cover. One thing to note is that infrared LED's do have a limited life since they are illuminating so they do burn out over time. Just because one camera has more LED's than another does not mean it can cast a longer distance, there are different strengths in the LED's. Unfortunately, again for the consumer it is hard to properly compare.
