- 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.
