Video surveillance systems are designed for real-time monitoring, registration and storage of video materials about events for further viewing and analysis. Modern video surveillance systems are implemented on the basis of digital processing of video information and IP data transmission systems. This makes it possible to analyze the video image based on intelligent modules. As a result, the need for human participation in viewing video recordings from multiple cameras is reduced by several times. In online mode, triggering on a specific event (for example, the passage of a car, the appearance of a person) allows you to raise an alarm and attract the attention of the guards.
A modern video system today can perform the following intelligent functions:
Face detection, face recognition with their identification;
Detection of objects, human figures, cars;
Detection and recognition of license plates;
Smoke and flame detection;
Control of abandoned items and Control of the disappearance of items of special importance (works of art, safes, documents);
A complex of intelligent modules for service industries (electronic queues, active zone control, cash register analytics modules).
Access control and management system, is a set of software and hardware technical means of control and management tools aimed at limiting and registering the entry and exit of objects (people, vehicles) in a given territory through "passage points": doors, gates, Checkpoint.
The main task is to manage access to a given territory (whom to let in, at what time and to what territory), including also:
restriction of access to a given territory;
identification of a person having access to a given territory.
Additional tasks:
accounting of working time;
payroll calculation (when integrated with accounting systems);
maintaining a database of personnel / visitors;
integration with a security system, for example:
with a video surveillance system;
with a security alarm system;
with fire alarm system.
A fire alarm is a set of technical means designed to detect a fire, process, transmit a fire notice in a given form, special information and (or) issue commands to turn on automatic fire extinguishing installations and turn on the actuators of smoke protection systems, technological and engineering equipment, and as well as other fire protection devices.
The main tasks of the functioning of the fire alarm system in conjunction with organizational measures are to save people's lives and preserve material values.
Modern fire alarm systems are divided into the following types:
- Conventional systems - in these systems, control panels determine the state of the alarm zone with detectors installed in it, without accurately determining the location of the alarm source.
- Addressable systems - significantly increase the efficiency of response to a fire by accurately determining the location (address) of the source of fire alarms in the building; in addition, these systems collect and process data on the state of the object and system.
A burglar alarm does not guarantee against intrusion, but significantly reduces it due to light and sound effects. The main task is to quickly notify property owners about the occurrence of an emergency.
There are many types of security systems.
A typical premises security alarm employs the following components:
- Alarm control panel: The "brain" of the system; reads sensor inputs, tracks arm/disarm status, and signals intrusions.
- Sensors: Devices that detect intrusions. Sensors can monitor doors and windows for openings or monitor unoccupied interiors for motions, sound, vibration, or other disturbances
- Alerting devices: these are bells, sirens and or flashing lights.
- Keypads
Security alarm systems differ in the method of signal transmission: wired and wireless.
In wired security systems, the sensors and the control unit are connected to each other by a cable. The advantage of such systems is the low cost of equipment.
In wireless security systems, the control unit and the sensor are connected to each other by radio signals. This simplifies installation where there are difficulties with the wiring. However, the cost of wireless equipment is higher compared to a wired system.
It is possible to connect a GSM module with the ability to control alarm functions from a cell phone.
The purpose of this equipment is to restrict, regulate the access of vehicles or people to the protected area. Bollards protect against vehicles entering the territory, sidewalks, etc. Bollards are divided according to the method of control into fixed, semi-automatic and automatic. By appointment - for conventional and anti-terrorist anti-ram. Barriers are used to restrict access to the territory of enterprises, car parks, etc. Turnstiles regulate the access of personnel, visitors or customers to the territory, stadiums, offices, etc. There are a large number of types of turnstiles that differ in purpose and design. Typically, these devices operate under the control of an access control system.
Paid / unpaid parking systems are designed to manage the entry / exit and parking of vehicles in the territory of Hotels, hospitals, shopping centers, airports, exhibitions, etc. The structure, construction and composition of the car park depends on the location, layout and parking requirements.
