Surveye installs access control systems to secure and protect your property, equipment, archives and vital data, the violation of which could cause significant damage in enterprises, public offices, banks, hospitals, parking area or warehouses.

The access control system protects the property and the people present in a reserved area.

Before choosing and installing an access control system, Surveye performs an accurate analysis in order to:

  • identify the number and type of entrances and exits to be monitored
  • estimate any damage that an unauthorised access could cause
  • define the security level required
  • identify the maximum number of persons passing through by day, zone and type of activity

Thanks to dedicated software, the access control system facilitates the flow of people. It is an excellent deterrent against unlawful acts and attempted theft. It makes use of identification devices, such as a PIN, RFID badges, cards and biometric recognition systems.

Access control is an important source of information regarding the state of occupancy of a building. The access control system can be used to optimize energy consumption or automatically activate the security system, as it can switch on the lighting system and regulate the ambient temperature in the areas actually used. In the event of a crisis, such as fire ignition, it guarantees complete control of the situation, in compliance with the company’s safety policy and, last but not least, checks the complete evacuation of people and customers from the area involved.

In any setting, be it a private company, a government organisation or a household, the access control system allows to:

  • know who enters and who leaves, when and through what point of access
  • know the identity of the person who enters a specific area
  • define restricted areas
  • determine a route and time for visitors and external operators

An access control system consists of the biometric and not individual recognition system, automated closing and connection to the system.


A recognition system generally consists of:

  • alphanumeric keyboard digital selectors
  • card and badge readers
  • proximity systems for smartcards and RFID badges
  • proximity systems with personal identification code (PIN)
  • biometric systems

The conventional recognition of an individual is by means of an object in his/her possession, which can be a badge, an ID card, a smartcard or a key, or data (PIN or password) known to the individual.

The biometric recognition system, instead, consists of the automatic identification, via a biometric reader, of the individual on the basis of any measurable unique physiological characteristics, e.g. hand or face geometry, fingerprint or retinal/eye. Biometric systems are the most advanced and secure personal recognition methods. Biometric traits cannot be stolen, passed to other individuals, nor can they be forgotten or lost.

Unlike in conventional systems, biometric information cannot be extorted (if not forcing the individual) nor used fraudulently. Access is enabled only after having verified, via the recognition system, the identity of the person who wants to enter a protected area.

Access can be opened using a simple local device, such as a door-opener, not connected to the control unit or a more sophisticated online access control system. In the latter case, the data detected by the biometric reader, a card reader or a keypad are sent to a server that processes the information and enables the control point.

Online access control systems also offer advanced features, such as:

  • the possibility to create profiles with different ratings
  • the recording of all access attempts and reason for refusal to transit
  • detailed access reports of the passage of each person or by time bracket, the tracking of passage times or break-in attempts.


There are several automated closing devices that can be connected to a people recognition system.

Tripod or full-height turnstiles
Surveye provides an installation service for tripod or full-height turnstiles, which are ideal for regulating the flow of pedestrians in areas with a lot of people on the move (offices, industrial complexes, stores, wellbeing facilities, gyms, airports, subway stations). These two-way turnstiles can also be configured for one-way direction. The access control terminal enables rotation in one direction only. The tripod is rotated via the force exerted by people passing through the turnstile. The mechanism operates with an RFID badge, card or centralised system. Surveye can also install full-height turnstiles suited to protecting outdoor areas, such as stadia where a high level of security is required. These turnstiles cannot be scaled or circumvented, can rotate in just one direction to permit entry or exit only, or can be controlled via an access control system that only permits the transit of authorised personnel. If equipped with biometric readers or other card-reading devices these turnstiles can permit access without checks by security personnel.

Motorized doors
Motorized doors are ideal for controlling heavy flow areas, such as undergrounds, airports, railway stations, stadiums and large companies. The operating mechanism is simple: the access control system verifies the identity of the subject and enables the system; the motorized gate doors then retract into the side slots to allow the individual to pass. Thanks to the integration with devices that detect the correct flow and count the people present, the motorized gates guarantee an efficient management of the traffic flow, avoiding disorders and chaos. The protected area can also be protected by alarm indicators, which activate when the door is forced. They are an effective deterrent to the passage of unauthorized people.

Revolving doors
Security revolving doors are used in high-risk settings (such as credit institutions and the stores of precious goods). They provide the ideal protection against intrusion, theft, break-in attempts and sabotage. They allow a preventive visual control and the possible blocking of any suspected person.
