Designing a video surveillance solution requires decisions on 7 fundamental questions. This blog series takes the customer through each issue explaining the basic options and reasons for selecting different available Video Surveillance System options. This is a blog series to help those new to purchasing a video surveillance or CCTV system. Its goal is to quickly identify the key aspects of video surveillance system design, not to examine the tiny specifics of different available technologies.
1. Security Camera Selection
Security cameras are literally the eyes of a video surveillance system. Cameras should be installed & deployed in critical areas to capture relevant necessary video. The two basic principles of camera deployment are (1) utilize choke-points and (2) cover valuable assets (3) Monitor Employees (4) Manage Business Processes to increase productivity.
In professional video surveillance, cameras are connected to video management systems (DVR / NVR / Software) for the purpose of Recording, Viewing and Archiving (managing access to video).
3. Video Management System
Video management systems are the core of video surveillance solutions. recording video from cameras, storing the video and managing distribution of video to viewers on the web or smartphone via VSIP. (Video Security over Internet Protocol)
Surveillance video is always stored for later retrieval, viewing, and analysis. The average storage duration is between 30 and 90 days. However, a small percentage of organization store video for much shorter (days) or for much longer (years). The two most important drivers for determining storage duration is the cost of storage and the risk and size of security threats an organization faces.
5. Video Analytics
Video analytics scan incoming video feeds to optimize storage or to identify threatening or noteworthhy events.
6. Viewing Video
Surveillance video is ultimately viewed by human beings. Most surveillance video is never actually viewed. Of the video that is viewed, the most common use is for historical investigations. Some surveillance video is viewed by live feed, generally in retail and in public surveillance. Most video surveillance is done periodically via archives in response to a ‘called-in’ threat or to check up on the status of a remote facility.
7. Integrating Video with Other Systems
Many organizations use surveillance video by itself, simply pulling up the video management systems’ client application to watch applications. However, for larger organizations and those with more significant security concerns, there is a more effective and efficient manner to perform security operations. Instead, these organizations prefer an approach where numerous security systems all display on a singular interface.
