    Default Home network speed for ip cams drops overnight and comes back in the morning.

    I have 4 networked ip cameras on my home lan.
    Normally speeds of data transfer are on average about 2000kb/s on each camera.

    This drops to about 150 to 600kb/s for each later in the day.

    Not affected if I turn off the cable router.
    Not affected if I reset the 4 port switch they go into.
    Not affected if I reset the NVR they are managed by.
    etc.

    Always improves again by the morning?
    Any clues?

    What else is on the network? Are you streaming videos to you home theatre using the same network? Kids playing games? What time does it improve? Is it the same time every day?
    I'm out of my mind, but feel free to leave a message...

    No streaming.
    Internet sitting idle. Makes no diff if cable router to Optus turned off.
    An internal issue.
    Timeline is similar each day. No specifics recorded.
    No backups, No upgrades ..

    Ive been researching it for a week now.. Lost atm.

    How are you measuring the throughput? Do you have any devices on the network capable of SNMP, so you can actually measure the traffic? What sort of network is it? 100Mb? 1 Gb? What sort of network switch are you using?

    I find that my IP cameras generate significantly more traffic at night. I guess it's just noise in the image from the dark/infra-red illuminated scene.

    are the cameras hardwired or wirelessly connected? If wireless, 2.4 or 5 G?
    What brand are the cameras? do they maybe enter some sort of night mode?

    approx 8:30 pm. Speeds all halved .

    Nothing changed here.

    800kbs approx for each.

    Checked for night mode settings but cant see any.

    Assuming it is showing what the actual data throughput is, A brightly lit image will require a lot more bandwidth (and / or data) than a darker or black and white image. So depending what the camera sees might be affecting what it actually requires...

    Is there any affect on your network otherwise?

    Yup. Streaming drop right down when ALL cameras drop to night vision.
    BUT not as low as the figures I was getting a week ago, just 1/2 speed.
    All seems to be working ok so that must be the way it works.
