Power Over Ethernet (PoE)

Dear sir/madam,

we have used the Persee camera with a PoE splitter. More specific, we have used this splitter https://www.aerial.net/shop/product/2180/ezynet-8023afat-to-5v24a-out.html
But, after 4-5 days of continuous running, the switch stops providing power and ethernet to the device.
Is it a problem that the splitter provides 5V and 2.4A?

If we use this splitter (Active PoE Splitter Power Over Ethernet 48V to 5V 2.5A IEEE802.3af | eBay), will we face similar problems?

In general, do you have tested with PoE splitter? Can you suggested one?

Thank you in advance.
