- Q:
What sort of technology is used in CCTV systems?
Answer:
The modern CCTV system involves a linked system of cameras
with full pan, tilt, and zoom able to be operated remotely
from a control room.
These systems may involve sophisticated technology. Features
can include night vision, computer assisted operation, and
motion detection facilities which allows the operator to instruct
the system to go on red alert when anything moves in view of
the cameras. Camera systems increasingly employ bullet-proof
casing, and automated self defense mechanisms which ensure
that cameras under attack are covered by neighboring cameras
These can be legitimately described as military style systems.

- Q: Can CCTV reduce
crime?
Answer:
Glowing reports of the effectiveness of CCTV are
announced regularly. CCTV deters 'opportunistic' crime, where
people take advantage of a situation on the spur of the moment.
The government is using CCTV as part of a long term plan
to reduce overall crime. "Today's opportunist is tomorrow's
professional criminal. If we decrease the number of opportunities
for easy crime, we can reduce the number of people becoming
professional criminals".
The cameras are also creating a vastly increased rate of
conviction after crimes are detected. Virtually everyone
caught committing an offense on camera pleads guilty nowadays.
Once people know they have been videotaped, they admit the
offense immediately. Police are delighted at the time and
money they are saving from long and expensive trials. Indeed
in some cases, people are surrendering after the mere mention
in news reports that their alleged activities had been captured
on CCTV.

- Q: What
is DVR ?
Answer:
Digital Video Recorder (DVR) is the next big thing
in CCTV surveillance technology. While analogue VCR recording
is still the most common method of recording, the benefits
of changing to digital recording will soon alter this situation.
Instead of using tapes to archive video, DVR system use
hard disk drives. This means that operator do not have
to constantly change tapes. Being digital data, there is
no degradation in the video quality.
Another benefit of
using a hard disk drive is random access. Just select the
date and time and footage of any part of
the video can be accessed within seconds. Operator can
skip ahead or go backwards to any date and time with ease.
The video can be paused and replayed while the DVR continue
to record the current live video in the background; an
impossibility with the VCR tape recorder.

- Q: Why
choose Digital Technology over Tradition CCTV ?
Answer:
Typical CCTV security system usually comprises of less than
16 cameras with a 20' foot field of view, a switcher, or a
multiplexer that records to a VCR. In the event of an investigation,
the authorities will ask for the VHS tape for evidence. Due
to degradation of video quality, the VHS tape
is one their weakest links. Today, digital solutions are a
vital effective security solution that meets the needs of the
federal authorities.
