    Dont take offense but I dont think the calculator is accurate.

     

    I have some SV3C IP Cameras (SV-B01POE-1080P) 1920 X 1080=2.1MP

     

    I used 3 bandwidth calculators to try and determine my bandwidth needs. On all calculators I entered 1920 X 1080p resolutions (or as close as the calculator would get)

    H.264 compression

    30 fps

    medium video quality

    1 camera

     

    Your calculator said I need 0.4mbps for local bandwidth (see attachment cctv calculator)

    Stardot said I need 8.2mbps (see attachment stardot calculator)

    Supercircuits said I need 6.27mbps (see attachment supercircuits calculator)

     

    How do you explain this?

    Hello,

     

    I have (3) 4MP cameras along with (5) 2MP cameras. These IP cameras use H.264 compression.

     

    I have all (8) cameras wired into a BV-Tech 8 port POE switch. https://www.amazon.com/BV-Tech-Port-Switch-Ports-Uplink/dp/B005GAATOG/ref=sr_1_3?ie=UTF8&qid=1517757535&sr=8-3&keywords=bv+tech+8+port+poe+switch

     

    I have the switch connected to a gigabit router. All cabling is cat5e.

     

    My PC based recorder has an AMD 8-core CPU @ 3.2GHZ and 16GB of RAM.

     

    When I add the cameras to ispy connect or blue iris software I get lagging video. The frame rate goes to 2-3fps on all cameras. My computer hardware seems to be suitable as the cpu doesnt go over 50% and 40% on ram.

     

    I thought the problem may be the POE switch because it is 10/100mbps and not 1000mbps but bandwidth calculators say the cameras stream at 8mbps per camera. That is 64mbps max.

     

    Why is my frame rate reduced?
