1. Front-End Cameras: - Bullet cameras, when used in conjunction with lenses, may necessitate additional lightning protection, especially for outdoor cameras. Lightning protection for both signal and power sources is a must, even more so when dealing with light bulb cameras, wireless cameras, and security cameras.2. Transmission Cables: - This includes both network cables and power cables. If P...
Video surveillance lenses play a critical role in video surveillance systems, as they're responsible for capturing real-time outdoor scenes and projecting them onto a screen. The collaboration between surveillance cameras and lenses is fundamental to the effectiveness of video monitoring.I. What Are Video Surveillance Lenses?Video surveillance lenses are in charge of capturing real-time video s...
1. Logical Structure: - Network video surveillance systems are composed of a central management platform, front-end devices, support systems, transmission networks, and clients. The central management platform plays a pivotal role in controlling signals and commands, facilitating media exchange, managing users, overseeing business operations, network management, billing, and statistical analysi...
The development of network video surveillance technology has progressed through four key phases:(1) Close-Range SurveillanceDuring the early stages of video surveillance, the primary approach involved using video coaxial cables to transfer video images from the front-end surveillance points to the central monitoring center. These images were then displayed on monitoring devices. As the number o...
