BRIEF SUMMARY
DESCRIPTION
The present invention relates to a system for surveillance of premises. It also envisages a method employed in this system.
From now on premises are understood to mean any bounded space taking the form of a building, real estate, individual or multi-occupancy housing, and more generally any premises for industrial, commercial, social, administrative or private purposes.
In what follows, the action of badging means that a person submits his personal badge, in practice a card provided with personal identification means, to be read by a badge reader, either in order to obtain access or in response to a call from this reader.
Effective surveillance of premises covers two essential aspects: on the one hand, control of access to these premises, and on the other hand dealing with alarms in the event of intrusion or unauthorised presence in these premises.
Present-day access control systems employ equipment for reading badges or cards, a processing and control centre and access-control devices.
Present-day alarm systems employ intrusion detectors, a control and processing centre, alarm devices and remote transmission equipment. These alarm systems generally employ two levels of security: protecting the external accesses of the perimeter of the building, securing the interior of the premises. alarm system available. In the majority of cases, and in particular in small buildings, these systems are not coupled or even connected, and those responsible for these systems have to carry out parameter setting and programming of these two systems separately. This entails significant risks of malfunctioning between the two systems entailing, on the one hand, inconvenience for the users of the premises in question and, on the other hand, risks of jeopardising the surveillance of these premises. This inconvenience and these risks may occur principally in extreme situations such as at the start and end of a period of inhibition of the alarm, on non-working days and the day before a holiday period.
The document U.S. Pat. No. 4,689,610 discloses a system for security and access control for protecting a set of protection areas, comprising access-control equipment, equipment for detecting intrusion or unauthorised presence in the protected regions, and provided with a programming timetable defining working periods and surveillance periods corresponding to the intrusion-detection equipment being put into service. This system allows postponement of the activation of volume-detection equipment by a predetermined derogation period whenever the access-control equipment, during the surveillance periods, validates a presence of, or a request for access from, an authorised person provided with personal identification means.
The document U.S. Pat. No. 4,327,353 discloses a security system employed particularly for surveillance of vehicles or premises, using a coded electronic key, and a decoder configured to receive this electronic key. This system is de-activated with the key itself and activation postponements are provided to allow movements within a security-protected area.
The document U.S. Pat. No. 5,057,817 discloses a multi-area intrusion detection system comprising a supervision circuit configured to verify, on the basis of normal activity or traffic in each of the protection areas, although the system is disarmed, that each intrusion detector is actually in working order.
The object of the invention is to remedy the abovementioned drawbacks by proposing a system for surveillance of premises which guarantees perfect coherence and synergy between the two alarm and access-control functions, without in any way requiring expensive control and processing installations which should be reserved for surveillance of large buildings, for obvious reasons of economy.
This objective is achieved with a system for surveillance of premises, comprising: identification means, means for reading these personal identification means and means for processing and granting requests for access to the premises, premises, comprising perimeter dete
