The most important thing to a person committing a crime is not being caught.
CCTV is a major deterrent as it means that not only does the criminal have to
contend with the crime but they must now also disguise themselves. This often
makes them stand out before the crime has been attempted.
With the latest forms of detection we can detect and record criminals before
they have attempted a break-in or theft. When these systems are remotely
monitored we can then either call the police or guarding service, or use a
public address system to warn them off.
In recent years the quality of recordings has increased dramatically. This is
mainly due to the use of digital technology within the CCTV industry,
providing better pictures at a dramatically reduced cost which has made the
systems so affordable that they are fitted not just to high risk businesses
but to homes as well.
A small domestic system will allow you to view around your house from your
television as well as to review recordings of previous day's activity from your
computer. You can if you wish even access the system from any internet point in
the world or from your smart phone!
Cameras no longer need to look like traditional cameras and can be discretely
located where you need them most and with the minimum impact to the aesthetics
of your building.
The best format to record a picture in is colour because this is the medium we
see in.
The problem with colour cameras is that as the light level falls the
picture soon begins to break up and become meaningless.
At low light levels monochrome cameras are far more sensitive. The solution is
a camera that is colour during daylight hours that becomes monochrome at night.
Moreover as monochrome cameras can be sensitive to infrared light that is
beyond the
human light spectrum we can also then equip the camera with an
infrared light source
so in effect they can see in total darkness. |
