The monitoring system comprises five main components: the camera, transmission, control, display, and recording & registration. The camera sends video footage to the control host via a coaxial video cable. The control host then distributes the video signal to various monitors and recording devices, while synchronizing any accompanying audio signals into the video recorder. Operators can use the control host to guide the pan-tilt mechanism and adjust the lens focus for up, down, left, and right movements. They can also switch between multiple cameras and gimbals using the control host. Advanced video processing features allow operators to input, playback, and refine images to optimize recording quality.
Monitoring system products include optical terminals, optical cable terminal boxes, gimbals, gimbal decoders, video matrices, DVRs, surveillance cameras, lenses, and brackets. The system’s structural elements consist of the front-end monitoring setup, management center, monitoring center, PC clients, and wireless bridges. Here's a breakdown of each component:
(1) Front-end Monitoring: Collects data from monitored areas and may include alarm systems.
- Standard Camera + Video Server: Analog or digital cameras transmit raw video signals to the video server, which encodes them before sending them over the network using TCP/IP protocols.
- Webcams: These integrated camera units combine camera functionality, video encoding, and web services, featuring an embedded TCP/IP stack for direct network connection.
(2) Management Center: Oversees the entire system, managing control, alarms, recordings, playback, and user permissions. Dedicated servers handle different tasks within this role.
(3) Monitoring Center: Centralizes surveillance across a specific region, including TV walls and monitoring client terminals. Multiple monitoring centers can exist within a single system.
(4) PC Clients: Beyond the monitoring center, PCs can connect remotely to the network for real-time monitoring.
(5) Wireless Bridges: Facilitate wireless data transmission and internet access. With these, monitoring data can reach wireless terminals or send control commands back to the video surveillance system on the IP network. Common networks used include CDMA.
In today’s world, surveillance systems have become indispensable tools for security and management. As technology evolves, these systems are increasingly incorporating smart features like AI-driven analytics, facial recognition, and predictive maintenance to enhance their effectiveness. For instance, some advanced systems now offer automated alerting based on predefined criteria, reducing human oversight and increasing efficiency. Additionally, cloud-based storage options provide scalability and flexibility, allowing users to access footage from anywhere with an internet connection. These developments underscore the growing importance of robust, adaptable surveillance solutions in both public and private sectors.
