What is CCTV?
CCTV or Closed Circuit Television refers to a visible or
covert video system intended for only a limited number of viewers. In Closed
Circuit TV (CCTV), the picture is viewed or recorded, but not broadcast. It was
initially developed as a means of security for banks and casinos; however,
today it has been developed to the point where it is simple and inexpensive
enough to be used with Home Security Systems, and for everyday
surveillance. For security there is
really no better way than video surveillance to deter theft or property damage
at your home and/or business. Security
cameras provide you with a way to monitor and record activity on your property
and the surrounding areas as well as letting people know you’re serious about security.
Different Types of Surveillance Systems
The components that make a CCTV system are single or
multiple cameras, a monitor and a recording device. A CCTV system can be divided into two types- the
wired CCTV system and the wireless CCTV system. As is quite evident from the name,
the wired system joins the above mentioned components together with cables
whereas, the wireless one has no monitor or a recording device connected to it.
Each of these types has their own advantages and disadvantages with respect to
the technology involved in them. Get an insight on both types.
Wireless CCTV Systems
This system has gained popularity because it is an easy to
install system. Lack of cables increases its value in terms of mobility.
There
are some key advantages of this system
-
One obvious advantage is that, it is easy to
move the camera to the place that requires observation. It is difficult to move
a wired camera as per your requirement.
- One obvious advantage is that,
it is easy to move the camera to the place that requires
observation. It is difficult to move a wired camera as per your
requirement.
-
This system is a great option for the places that require temporary observation. They can also be installed at temporary sites.
- The Camera in this system can be hidden too. This would help check theft and other kinds of crimes.
-
In this system, the recording and the monitoring device need not be
in the same line of sight to provide an observation from another remote
location.
- This system is not very expensive and is advantageous because it can be moved and deployed as per choice.
With a number of advantages, this system has a number of disadvantages
too:
-
The wireless CCTVs require a high frequency for
recording to take place in the recording station. Disturbed frequency would
mean low quality footage.
-
These cameras are observed to have low picture
quality.
-
The camera in the wireless CCTV system may
require an electricity connection despite the video being connected wireless.
-
The breakdown with this system is not easily
detectable and requires only experts to do the job!
Wired CCTV Systems
In this system the three components, the camera, the recording device
and the monitor are connected with the help of a cable. This system is advantageous
because:
-
It offers good picture quality.
-
The cameras can be a located a few metres away
from the monitor.
-
A single power supply is enough to control all
the sensors.
The main disadvantages of this system are:
-
This system requires time and man power to be
installed.
-
It has a limited range of observation and
cannot be easily moved from its place.
Both the systems have their pros and cons. The wireless one
because of its viability is preferred by many but the wired one is a choice for
those who want clear pictures and have a limited budget.
