By Raymond Shadman Custom Video Security 310-370-9500 x1 1. Define objective. What do you want to see, in what level of detail, and how far away? How many megapixels and what focal lengths are required to achieve viewing objectives? Are objects moving? If so, what size are they with respect to the field of view, and how fast are they moving? How many cameras will be on the system? (Most recorders or VMSes support a maximum number of cameras.) Will more cameras be added in the future? Are there multiple locations, and if so does the corporate headquarters want administrative control of each location? If so, would there be a network admin who would want to apply modifications to each location’s server in bulk using Federated Architecture (Milestone XProtect Expert or Corporate)? Will the system be recording on a schedule, continuously, on motion detection, or both? 2. System design. How many clients will be viewing the cameras simultaneously, and from inside or outside the network? (If a lot of clients viewing multiple cameras at a time on a Milestone Expert or Corporate system, a separate Mobile Server should be used.) Are clients PCs or Macs? Are mobile clients Android, iOS, […]

It is my job to keep up with fast past of new video security technologies, and to educate low-voltage installers, IT professionals, and consumers on the various types of video surveillance which are currently on the market. Before reading this post, one should educate himself/herself with a little background on how resolution of cameras and DVRs is measured. Older camera technology is measured in TVL or “horizontal TV-Lines”, while newer HD camera technology is measured in pixels (horizontal multiplied by vertical). The greater the number of TVL or pixels, the better the resolution. One of the biggest flaws of current analog technology is that the highest analog recording resolution is 960H (960×480), or 960 horizontal lines, but 1000 TVL cameras typically have 1280×960 pixels, or 1280 horizontal lines. This results in forced recording at 960H, even if the camera has higher resolution. That is the same concept putting a governor on a sports car to maximize the speed at which it […]
