Best thing would be to sell them on Ebay and get better cams, but I admit I still have one and it is working with BI.
@TonyR is correct the IP cannot be made static, so the first order of business is to get into your router and reserve IPs for the cams. You need to make sure the IPs don't change at a power cycle.
Then you can configure BI.
Is you the POE cable running from the camera into the original Logitech power supply still? I don't seem to be able to see the cameras using the IP scanner tool. Thank you
