We are now using
and can supply and install various security devices, specially
designed to work on computers. These systems can either use an
existing computer or network, or be used on a dedicated unit specially
designed for them. Due to the reduction in
cost of PCs and the availability of specialised security software and hardware,
they can now be considered as an affordable alternative to traditional monitoring
and recording devices, e.g. time lapse VCRs, monitors multiplexers etc. Digital
systems can offer many advantages over traditional systems, some of which are
- Speed of Operation
- Digital Image
- Less Labour
- Less Maintenance
- Can use Existing
- Remote Monitoring
- Easy Future
Speed of Operation
When an alarm condition is detected, by PIR
detector, door contact, panic button, motion detector
or any other type of input, the computer can trap the
desired length of action within 1/10th of a second. The
speed of this reaction means that "activation only
recording" is now an economical proposition, in
many circumstances this can be a much more efficient
method, especially where multiple camera systems exist.
There are many benefits from "activation only recording" that
can be beneficial to any business.
- No need to
review hours and hours of tape, resulting in great savings in
both labour costs and staff satisfaction.
- Can be used
to monitor staff movements throughout your establishment, e.g.,
stock room doors, fire doors, cars or people entering and leaving
car parks etc.
- It's ideal
for monitoring little visited areas and remote sites, as there
is no need for staff to visit the sites to change the video tapes,
that have been recording nothing.
- By using a
modem and alarm can be triggered and the reason for the alarm
confirmed over a normal telephone line by viewing both the live
and the recorded video, so reducing false alarms.
Digital image Storage
Because the images are stored as digital information inside the computer there
is no need to keep replacing worn out video tapes in order to keep up the quality
of the image.
- There is no
degradation in picture quality when copied, unlike
videotape which degrades each time.
- The images
generated can be enhanced, using the software package included,
allowing you to digitally zoom in, alter the brightness and contrast,
sharpen the image and many other useful features. This can be
useful for blowing up a number plate, for example.
- Being digital,
the image can be saved to floppy disc, sent down telephone lines,
transferred to video or printed out on paper.
Longer Life and Less Maintenance
Because of its digital design and the extra
design features that we have built in, the computer should
prove far more reliable in the
- There is no
requirement for the routine maintenance, of the type associated
with VCRs, e.g. head cleaning and replacement etc.
- The computer
system is also less likely to become obsolete as time goes by,
being easily updated with new software.
- There is less
need for staff to visit sites just to change tapes when maybe
there has been no activity.
Can Use Existing Equipment
Where there is a suitable computer already installed, the hardware and software
can be simply added to it, allowing the computer to be used for its normal
tasks, while the security software runs in the background.
- Reduces cost
of buying VCRs, monitors etc.
- Allows for
colour cameras to be used at reasonable prices.
- Easily expanded
by using inexpensive hard disc memory.
- Very useful
for schools & colleges, where computers are idle
in the holidays & changing tapes means visiting the premises.
