Network Bandwidth & Storage Consideration are very important when designing a video surveillance system. Common factors to consider are; quantity of cameras, image resolution used, compression type/ ratio, frame rate and viewing area complexity.
Bandwidth: When installing a small surveillance system involving 8 to 10 cameras, a basic 100Mb network can be used without considering bandwidth limitations. Most video surveillance systems of this size can be implemented on an existing 10/100Mb network.
Cameras that are configured to deliver high-quality images at high frame rates will use approx. 2-3Mb of network bandwidth. Once you install more than 12-15 cameras, you should plan to use a Gigabit (GB) network. Using VLANs, Quality of Service (QoS) & Event-Based Recordings will help manage the bandwidth consumption.
Storage Calculations: IP-Based Video Surveillance Storage is based on configuration, like the following;
♦ Quantity of cameras
♦ Will recording will be continuous or event-based
♦ Quantity of hours per day the camera will be recording
♦ Frames Rate (frames per second/FPS)
♦ Image resolution
♦ Video compression type (Motion JPEG, MPEG-4, H.264)
♦ Scenery: Image complexity, lighting conditions & amount of motion
♦ How long do you want data stored
Storage can be on a Network Video Recorder (NVR) on-site or at another location. Some IP-Cameras provide storage on an SD Card installed in the camera. Cameras can also stream to Cloud based storage.
