Practical Value of Video Surveillance
Video surveillance systems are popular due to their multifunctionality and practical benefits. They address the following tasks:
- Theft Prevention: Video surveillance acts as a deterrent for potential intruders and assists in investigating thefts that have already occurred.
- Improved Discipline: Video recording of employees’ working hours, monitoring compliance with work schedules, and overseeing production processes.
- Prevention of Abuse: Monitoring staff actions to prevent misuse of material assets and financial resources.
- Enhanced Overall Security: Video surveillance increases the security level of the facility, reducing the risk of unlawful activities.
Components and Types of Video Systems
A basic video surveillance system consists of the following components:
- Cameras: Devices for capturing and transmitting video information.
- Processing and Playback Equipment: Monitors, switches, and other devices for processing and displaying video signals.
- Recording Equipment: Video recorders, video servers, and other devices for storing video data.
- Connecting Elements: Cables, switches, routers, and other components for data transmission between system elements.
Depending on the objectives, a video surveillance system can be enhanced with additional devices such as motion sensors, alarms, routers, etc. Optional equipment expands the system’s functionality, for example, enabling scheduled recording, integrating video surveillance with access control systems, or security alarms.
Classification of Video Surveillance Systems
Video surveillance systems can be classified in several ways:
- By Coverage:
- Remote (Distant) Video Surveillance: Allows monitoring of a facility from a distance.
- Local Video Surveillance: Used for monitoring within a single area.
- By Interaction Method:
- Wired Video Surveillance: Data transmission occurs via cables.
- Wireless Video Surveillance: Data transmission occurs via wireless communication channels.
- By Video Data Processing Method:
- Digital (IP Video Surveillance): Uses the IP protocol for data transmission.
- Analog Video Surveillance: Data transmission occurs in analog format.
Additionally, there are other classification methods, such as by the type of recording device (video recorder or video server) or by the installation method of cameras (hidden or visible).
