Calculating CCTV Bandwidth Needs, Computers, TVs and Cellphones. To calculate the minimum bandwidth requirement (mbps) for the CCTV devices, computers, TVs, and some of the cellphones mentioned, we need to calculate the total bandwidth requirements for all of these devices. 1. CCTV Camera: - CCTV cameras connected to WiFi networks usually require a bandwidth of around 1-2 mbps for standard quality video streaming (480p) and 2-4 mbps for high quality video streaming (720p-1080p). - If there are 21 CCTV cameras, then the minimum total bandwidth required for CCTV cameras is 21 x 2 mbps = 42 mbps for standard quality video streaming and 21 x 4 mbps = 84 mbps for high quality video streaming. 2. Computer: - Bandwidth requirements for the computer will depend on the activity being performed. For example, browsing the web requires around 1-2 mbps, streaming standard quality video requires around 3-4 mbps, and streaming high quality video requires around 5-8 mbps. - If there are 3 computers and all are used for web browsing and standard quality video streaming, then the minimum total bandwidth required for the computers is 3 x 2 mbps = 6 mbps. 3.TV: - The bandwidth requirement for the TV also depends on the quality of the video being played. Standard quality video streaming requires around 3-4 mbps, and high quality video streaming requires around 5-8 mbps. - If the TV is used for high-quality video streaming, the minimum total bandwidth required for the TV is 8 mbps. 4. HP: - Bandwidth requirements for HP also depend on the activities carried out. For example, browsing the web requires around 1-2 mbps, streaming standard quality video requires around 3-4 mbps, and streaming high quality video requires around 5-8 mbps. - If several cellphones are used for web browsing and standard quality video streaming, then the minimum total bandwidth required for cellphones is around 10-20 mbps. So, the total minimum bandwidth requirement for all devices is: - Standard quality video streaming: 42 mbps + 6 mbps + 8 mbps + 10 mbps = 66 mbps - High quality video streaming: 84 mbps + 8 mbps + 8 mbps + 20 mbps = 120 mbps Thus, the minimum bandwidth requirement for all devices is around 66 mbps when used for standard quality video streaming and around 120 mbps when used for high quality video streaming. However, this is only a minimum estimate and it is best to consider other factors such as available internet speed and actual user activity. #youshe #bandwidth #indihome
