Study Notes
ANPR Cameras in Surveillance Systems
- Primary function is automatic number plate recognition, enabling the identification of vehicles by reading their license plates.
- Commonly used for security, toll collection, parking management, and traffic monitoring.
Hikvision's SAN Solutions
- Essential feature is high availability, ensuring that storage is always accessible and reducing the risk of data loss.
Video Wall Solutions
- Critical aspect for synchronization of displays is the refresh rate, ensuring all screens update simultaneously for seamless viewing.
Distinction of IP Cameras
- IP cameras provide higher resolution images compared to traditional analog cameras, allowing for more detailed footage.
- Use digital signals transmitted over networks, enabling remote access and integration with other smart systems, unlike analog cameras that rely on coaxial cables.
Server Architecture for Video Surveillance
- Benefit of using dedicated servers is optimized performance, as these servers are specifically designed to handle high bandwidth requirements and multiple camera feeds without lag.
- Offers enhanced reliability, security, and scalability compared to general-purpose servers which may be overloaded by varied tasks.
