VISIOPHONES: FRENCH HIGH TECH SECURITY
|
||
|
||
By
|
||
|
||
Pierre Marie Bourniquel
|
||
Commissaire Principal, Chief of Police
|
||
Biarritz, France
|
||
|
||
|
||
High-tech security techniques, which may become commonplace
|
||
in the next century, are being tested in the French resort city
|
||
of Biarritz. The visiophone, a device that transmits both audio
|
||
and visual images across fiber optic lines, is being used by the
|
||
Biarritz Police Department to augment traditional policing
|
||
techniques. The device provides personnel in the police station
|
||
the opportunity to access visually the interiors of offices,
|
||
stores, nursing homes, and some residences in the city. While
|
||
this pilot program began small, it has grown to include over
|
||
1,500 units and has changed policing methods and public
|
||
perception about police effectiveness.
|
||
|
||
BIARRITZ AND THE VISIOPHONE
|
||
|
||
Biarritz, once a renowned resort destination for American
|
||
and European vacationers, had fallen on hard economic times
|
||
after its popularity was eclipsed by other resort areas on the
|
||
Atlantic and Mediterranean coasts. However, when French
|
||
Telecom, the French telephone company, began to search for a
|
||
suitable site for its visiophone pilot program, Biarritz met the
|
||
requirements and was chosen due to several important factors:
|
||
|
||
* The experiment was to take place in a medium-sized city;
|
||
the population of Biarritz, though it swells to 100,000
|
||
in the summer, remains at about 30,000 during the
|
||
remainder of the year.
|
||
|
||
* The city's old telephone network needed refurbishing.
|
||
|
||
* The city's geographical location and population, largely
|
||
made up of retirees, was well-suited for the visiophone
|
||
experiment.
|
||
|
||
The visiophone itself is a compact device, measuring 47cm
|
||
(18") wide, 42cm (16") deep, and 30cm (11") high. It includes a
|
||
17cm (3") square screen, a detachable camera on the right side,
|
||
a telephonic module, a full keyboard (with numbers and letters),
|
||
and a voice amplifier. The instrument, which has the ability to
|
||
access Minitel (the Telecom computer), produces either
|
||
black-and-white or color images, depending on the type of camera
|
||
used.
|
||
|
||
For this program, installation of the visiophone is free,
|
||
with monthly costs averaging $14.50. Visiophonic calls are
|
||
billed at the same rate as regular telephone communications.
|
||
|
||
The initial network of 50 subscribers in 1985 has steadily
|
||
grown. While security was not the motivation for the
|
||
development of this pilot program, it quickly became obvious to
|
||
the local police that the system offered potentially valuable
|
||
applications in the realm of enhanced security, especially for
|
||
the large population of elderly citizens in Biarritz.
|
||
|
||
POLICE USE OF THE VISIOPHONE
|
||
|
||
Telesurveillance
|
||
|
||
A number of banks and businesses throughout the city have
|
||
alarm systems that are connected to police headquarters. These
|
||
alarms are activated accidentally several times a day, resulting
|
||
in wasted time and effort by the police. But now, when an alarm
|
||
sounds, it is possible to conduct an initial investigation of
|
||
the establishment using the visiophone.
|
||
|
||
In a usual case, the watch officer contacts the business by
|
||
visiophone once an alarm sounds, and requests that a visual scan
|
||
of the interior be conducted using the detachable camera. All
|
||
doubt can be resolved without an officer leaving the precinct.
|
||
However, if doubt remains--no answer to the visiophone, poor
|
||
vision through the camera, or suspicious activity observed in
|
||
the premises--a patrol is dispatched immediately. The patrol
|
||
then knows that this may not be a routine call and will
|
||
naturally exercise more caution.
|
||
|
||
Visiophonic Patrolling
|
||
|
||
As mentioned earlier, the population of Biarritz includes a
|
||
significant number of elderly persons. The majority of these
|
||
retirees have worked elsewhere and now find themselves isolated
|
||
from their families. Many have developed a sense of insecurity
|
||
fueled by accounts of rising crime rates.
|
||
|
||
It is the responsibility of the police, to some degree, to
|
||
ease their feelings of insecurity. To this end, a plan was
|
||
developed, in late 1988, to integrate the visiophone with the
|
||
traditional patrol function.
|
||
|
||
This plan involves 500 subscribers and impacts
|
||
approximately 1,000 residents of the community. The initial
|
||
effort required beat officers to contact residents over the age
|
||
of 65 personally and provide them with a written explanation
|
||
describing the program. These residents were then informed that
|
||
if they desired, the police would contact them about twice a
|
||
month by visiophone.
|
||
|
||
Visiophonic patrolling is not intended to replace the
|
||
traditional patrol function. Instead, it is meant to supplement
|
||
it. The visiophone allows the police, in a sense, to enter the
|
||
door of the elderly and reassure them concerning their security.
|
||
Because many of the elderly reside in high-rise apartment
|
||
buildings, the opportunity for door-to-door personal contact by
|
||
the police is significantly reduced. The visiophone provides a
|
||
more-intimate level of contact than ever before possible in
|
||
these situations.
|
||
|
||
Answering the Call
|
||
|
||
The visiophone is, of course, a two-way system, allowing a
|
||
citizen with the device to call the police and be greeted by the
|
||
reassuring image of an officer on the screen. When an emergency
|
||
call is placed, the watch officer can view the interior of the
|
||
premises and maintain audiovisual contact with the caller while
|
||
the patrol is making its way to the scene. This has proven
|
||
particularly reassuring, especially to elderly residents who
|
||
become very anxious when facing a potentially dangerous
|
||
situation feeling isolated and alone.
|
||
|
||
RESULTS
|
||
|
||
Early reaction to the police use of the visiophone has been
|
||
very positive. Residents and businesses have expressed
|
||
appreciation and a new level of regard for the police since
|
||
visiophonic patrolling and telesurveillance have been
|
||
instituted. Factors contributing to the success of the
|
||
visiophone program were studied by the National Center of
|
||
Telecommunication Studies (France). The NCTS drew these
|
||
conclusions:
|
||
|
||
* 90% of the elderly persons surveyed are very satisfied
|
||
with the type of police contact made available by the
|
||
visiophone.
|
||
|
||
* The visiophone provides a much more efficient means of
|
||
communication than the telephone, since during a typical
|
||
conversation, as much as 40% of the message is
|
||
communicated by gestures and countenance. The
|
||
visiophone permits the communication of the visual
|
||
signals that the telephone misses.
|
||
|
||
* Because communication via the visiophone is interactive,
|
||
rather than passive, more information is retained by the
|
||
citizen during a conversation.
|
||
|
||
In addition, the visiophone is rapidly becoming a valuable
|
||
investigative tool, allowing a large number of contacts in a
|
||
relatively short time. Officers can attain visual contact of a
|
||
victim, witness, or potential suspect before ever leaving the
|
||
precinct.
|
||
|
||
CONCLUSION
|
||
|
||
The technology of the 21st century is augmenting, not
|
||
replacing, traditional police functions in Biarritz, France.
|
||
Personal contact with victims and witnesses is still an
|
||
important responsibility of the police department, as is sound
|
||
investigative work and code enforcement. However, advances in
|
||
technology, such as the visiophone, are providing law
|
||
enforcement with unprecedented opportunities in the realm of
|
||
security and surveillance that can be realized today. In this
|
||
pilot program, both the police and the residents of the
|
||
community are discovering that modern technology can be used
|
||
effectively and responsibly to enhance security and to expand
|
||
the protection and services offered by law enforcement.
