Hi Dmitry –
I think the network issue is actually with the power. You have a mix of cameras with different PoE needs, so I’m surprised that they’re powering up at all.
We do have solutions to power the cameras with the 24v60w power supply you have.
* Foscam FI8910E – needs 802.3af (48 volt) PoE. Use our 48v step up converter:
* Foscam FI8910W – needs a 5 volt PoE splitter: https://find-a-poe.com/product/POE-5v10w/
* iCamera 1000 – needs a 12 volt PoE splitter: https://find-a-poe.com/product/WS-POE-12v/
* 2x Midas-Link ML-203W – is PoE capable, but I’m unable to find a datasheet that specifies if it needs standard PoE. If so, you can use the 48v step up converter, or you can switch to our 48 volt 60 watt power supply and use our PoE splitters for higher voltages:
