This guide has been developed to assist customers with those decisions that are needed to successfully plan a video security system. The guide does not pretend to be comprehensive, but rather, the goal is to provide a tool that initiates a fruitful conversation between the customer and the professional.
Questions that are Relevant to Almost Every Application:
How many cameras will be needed?
What camera is the best for each application?
What type of video management system is appropriate?
How Many Cameras will be needed?
The number of cameras will directly affect the attributes of the video management system. The design of video security systems is usually based on monitoring key assets and choke points, for example, building entrances. You can get HD picture quality with the help of top quality cameras.
The number of cameras will directly affect the video management plan. For these purposes, it is better to "pad" the estimate, as it is normal for new needs to evolve.
What Type of Video Management System is Appropriate?
Video management systems are the logical center of the video surveillance system, receiving data from the cameras, storing the video, and interfacing with the rest of your information system. At installation, this system's importance will not be obvious, but as you utilize the system, this module will become very familiar.
All modern video management systems have at their core a computer. Some systems use a generic P.C. with video acquisition hardware added. This is usually the cheapest and most versatile option, but is also the most maintenance intensive, and least reliable.
The other option is a digital video recorder (DVR), which indeed includes a computer, but the computer is not a generic P.C., but is instead is an embedded computer with hardware and software designed specifically for the job of managing a video security system.
