CCTV: A VALUABLE ADDON FOR YOUr BUSINESS
With the public perception of crime increasing,
now is the time for locksmiths and other security
businesses to consider offering businesses and home
owners valuable add-on services such as CCTV. The
experts from Rhinoco offer this useful guidance.
Just what does installing
CCTV involve? Do you
need a qualification?
CCTV is run on 12 volts,
technically plug and play, so
there is no need to be a “Part
P” registered electrician.
As with many industries,
there are calls from public
bodies for regulation, but
at the moment and for
the foreseeable future
anyway, no registration or
qualifications are needed.
The cost of entry into the
install market is minimal –
drill, ladder and screwdrivers
being the only essential
tools, which makes it an ideal
bolt-on service with potential
income benefits.
There are three main types of
CCTV systems available at the
moment
Analogue Systems
These are the traditional
CCTV systems. Camera
resolution (picture quality)
is measured in television
lines (the number of lines the
picture is made up of ). The
higher the TVL, the higher the
picture resolution, the clearer
the picture. Analogue systems
are the cheapest on the market
and with technology ever
evolving – high TVL’s of 800
are achievable. The systems
can be wired using a variety of
cables – coaxial, shotgun and
Cat5.

Digital Video Recorders
(DVR’S) are the recording
units used with analogue
cameras. Special features on
the DVR allow you to record
on movement detection,
email you if an event happens,
trigger an output such as
an alarm as well as view
anywhere in the world via
interent or smart phone.
IP CCTV cameras use digital
technology with picture
resolution is measured in
megapixels. The more pixels
the higher the resolution, the
clearer the picture.

A 1.3 mega pixel camera is
1280 x 1024 pixels. A 520 TVL
analogue camera equates to
752 x 582 pixels. IP cameras
therefore clearly deliver much
greater image detail than
their analogue counterparts
allowing greater surveillance
coverage and providing greater
detail and accuracy.
Beacuse IP cameras capture
an image in a digital format,
the image can be dissected,
zoomed in, masked off and
analysed without distortion.
Network Video Recorders
(NVRs) are the recording
unit allowing you run these
analytics and allow much
greater data manipulation
than DVR’s as well as the
normal functions of a DVR.
IP systems use CAT5 cabling
and have the advantage of
being able to utilise current IP
network infractures that might
be in place but are expensive
in relation to analogue
systems.
CVI systems bridge the gap
between IP and analogue.
They offer HD quality –
megapixel images, over
coaxial, shotgun and CAT5
cable, just like analogue
system. Unlike IP systems
however, they do not act as a
network device.
CVI systems are ideal for
those wanting to upgrade
their existing analogue
systems without the need
for re-cabling. Camer
