The Evolution of Video Surveillance Technology
The development of video surveillance technology has undergone significant transformations over the years. Let's explore the different eras that shaped the landscape of video monitoring: First Era: Analog Video Surveillance This era began in the 1970s with analog video surveillance equipment. The transmission was primarily achieved using coaxial cables, and the video signals were analog in nature. The recordings were stored on VCRs (Video Cassette Recorders). However, the limited storage capacity of VCR tapes led to frequent tape replacements to enable long-term storage. The analog video surveillance era faced challenges such as low automation efficiency... -
Monitoring Transmission Bandwidth and Storage Capacity Calculation
In surveillance systems, calculating the required bandwidth and storage capacity is essential to ensure smooth and efficient operations. At WEILAILIFE, we offer solutions to help you determine the optimal bandwidth and storage needs for your surveillance setup. Here's a step-by-step guide to calculate both: Bandwidth Calculation: Network Bandwidth Size = Bitrate Size × Number of Cameras Note: Some professional sources may refer to "bitrate" as "bit rate." For our understanding, "bitrate" represents network speed, while "bit rate" refers to the size of monitoring video produced per second. Bandwidth at Camera End: Refers... -
Monitoring Project: Various Power Supply Options for Surveillance Camera Installation
In the field of surveillance engineering, selecting the appropriate power supply method for surveillance cameras is crucial for optimal performance. At WEILAILIFE, we offer a range of power supply solutions to meet diverse installation requirements. Here are three main power supply options: Independent Power Supply Mode In the independent power supply mode, each camera is equipped with a dedicated security monitoring power source, providing power supply exclusively for one camera. This setup ensures individual power stability for each camera, enhancing reliability and minimizing the risk of power-related issues. Centralized Power Supply Mode ...
